                              Important Installation Points
The unit must be installed to comply with national regulations and/or codes of practice. A qualified
electrician must carry this out.

Ensure at least 39” (1000 mm) clear front access to the electrical and steam sections of the
cabinet.

Do not locate the cabinet where the ambient temperature around the unit could exceed 95ºF (35ºC)
or fall below 40ºF (5ºC) e.g., an unventilated roof mounted enclosure – see minimum space /
ventilation requirements page 5.

Do not locate the cabinet where a ladder is required for service access as this could make
servicing and cylinder service or exchange hazardous.

Make sure steam line(s) have adequate slope (min 12%) for condensate drainage and use
condensate separators if the pipe is lower than the unit.

Provide adequate support to prevent sags developing in flexible steam lines, which can fill with
water and create a "trap".

Do not locate vented drain directly under the cabinet.

It is important to select the correct water type, see table on page 7, your water supply company
should be able to provide the required information free of charge.

                           Important Electrical Connection Items
Before commissioning the unit, check that all electrical (power) connections - including those at
the terminals and contactor are tight.

Check that the transformer primary winding connection is correct for the supply voltage at Vapac
terminals A1 & A2.

The Vapac transformer must not be used to power other equipment.

To comply with EMC aspects see recommendations on page 9.

Use a high-limit humidistat to ensure positive interruption of unit operation when over-
humidification is detected (see p14).

It is important that the control signal connected to terminals 5 & 6 must be referenced to ground at
the control PCB – this can be done by linking either terminal 5 or 6 to terminal 7.
       NB if the controller output is referenced to ground, it is important that the “leg” which is
   connected to ground at the controller is also connected to ground at the Vapac unit. Grounding
        the opposite “leg” will cause damage to the controller and/or the Vapac control PCB.

                                Important Maintenance Items
Only a qualified electrician should carry out maintenance.

The boiler contains hot water, and must be drained before any maintenance is carried out on the
steam section. This should be done prior to isolating the power, and removing the front access
panel

ESD SENSITIVE DEVICES USED ON PCB. ENSURE ANTI-STATIC PRECAUTIONS ARE TAKEN
WHEN REMOVING OR REPLACING PCB’S.

   conduit where practicable. The earth must be made                     Cables to control terminals
   by "metal-to-metal" contact and should be a good RF
   (Radio Frequency) earth.

   The control and security circuit connections should be
   run in screened cable with the screen grounded at the
   VAPANET end (onto the electrical section back panel).                                 Screen left intact
   The screen should be maintained as close as possible
   to the cable ends and any tail between the screen and
   the earth point must be kept short (50 mm maximum).

1.4.2     Power Supply Connection
The unit requires the following connections as shown in the
diagram below




1.4.2.1 Volt free alarm outputs
The unit has connections for volt free alarm outputs these are
on the three double terminals next to the main power input
terminals.
The top terminals are for unit volt free fault alarm as follows:
           542      common for fault alarm
           543      Normally closed when no fault
           544      Normally open when no fault

The bottom terminals are for unit volt free run signal as
follows:
         545     Common for run signal
         546     Normally closed when unit is in standby
                 or fault (not running)
         547     Normally open when unit is in standby or
                 fault (not running)
         548
If the unit is part of a master slave system or network,
the run & fault outputs can be selected (via keypad &
display) as either network (system) or unit only. This is
selectable at Service Engineers Level, in the
Engineering Menu, in the window “Fault/Run Scope”.
The default is “network”. It is possible to get both
alarm & Run indication in all units: Single cylinder units
will give this indication if the service interval has
expired; Twin Cylinder & Networked units will give this
indication if the service interval has expired or if the
master cylinder is operating and any slave cylinder (or
cylinders) are in fault.

inhibit the operation of either the unit or in the case of
twin cylinder units unit or just the 2nd cylinder. This will
limit the power used during peak supply periods. If
this option is selected, the fan interlock, airflow switch
and/or high limit hygrostat should be wired into
terminals 9 & 10 with the EPO switch if fitted (as per
the drawing on the far right). It should be noted that
selection of this option will mean that frost protection
cannot be utilized.

Please note that if a display is connected to the
unit “DI1 Control Option” must be set to the
following:
Single cylinder units: “Load shed”.
Twin cylinder units: either “Load Shed Cyl 2” or
“Load Shed Both”.

        1.5.8        Master/Slave System

For larger duties, VAPANET “Resistive heater” units can be interconnected and arranged to operate from one proportional signal as a
Master/Slave system. The system allows up to 10 cylinders to be linked in this way. The slave units will all be “on / off” units. The master
unit, to which the proportional signal is connected, can be “on / off” but will preferably be a “proportional” unit.
To “configure” a system, ensure that the control signal is zero [disconnect the control signal, or switch the units off at the front panel switch].
Press and hold the service pin on the master control PCB, until the user LED’s flash amber, release and check that the LEDs flash
red/amber/green, if not repeat the procedure. Then press the service pin on each of the slave control PCB’s in the order that they are
required to operate, the slave user LED1 will flash Green/amber until it is configured, once the light goes out [or flashes red/off], proceed to
the next slave. If units of different capacity are used, ensure that the master is equal to or greater than the capacity of the slaves, and that
the largest capacity slaves come on before the smaller capacity units]. Once this process is complete, confirm the fact by pressing the
service pin on the master PCB until user LED2 goes green [this step is not necessary if all nine slave cylinders are configured].

        f)       The maximum output & kW rating of the unit
                 is determined by the number and electrical
                 rating of the heater elements fitted in the
                 cylinder. It is not possible to “de-rate” the
                 unit.
        g)       Unit Configuration Plug (U.C.P.). Provides
                 the Vapanet control PCB with information
                 regarding the “system hardware” i.e. the size
                 of the cylinder and whether the unit is an
                 “On/Off” (“LR”) or “Proportional” (“LRP”)
                 model. It is fitted directly onto the control
                 P.C.B. If a display is fitted only one resistor
                 is fitted to the UCP, but if no display is
                 present additional resistors need to be
                 present to provide sufficient information for
                 the unit to operate. If insufficient information
                 is available the unit will remain in the
                 “not_config” state until the information is
                 supplied. This additional information is
                 provided via the keypad – when the display
                 is fitted.

b)       That the security circuit is closed for unit                 If no security circuit is fitted (i.e. no airflow switch or
         operation.                                                   high humidity override hygrostat is required)
                                                                      terminals 9 & 10 must be linked.
Replace the electrical access panel.
Turn on the water supply to the unit.
Close disconnect/circuit breaker feeding supply to the unit.
Close the On/Off switch.
The display (if fitted) will now show the Set-Up procedure.
Follow the procedure by:
-     selecting: the preferred language,
-     Attaching the control PCB to the Display.
-     nominating: the type/quality of the supply water.               If no display is fitted, the selections are made by
-     nominating: the control signal (or Vapac sensor when            fitting jumper plugs to the “Configuration PCB” (Part
      being used).                                                    number 1150634). See page 13.
When the control signal has been nominated, the Set-Up will be
entered into the memory. The Set-Up can then be checked by
reading the information menu. If an error has been made, it will
be necessary to go back to the Set-up menu. If no display is
fitted the information is set using the jumpers on the small
resistor PCB 1150634, fitted to CR4 of the control PCB.
2.0.3    Commissioning/Start-Up
Once the Set-Up procedure has been completed, the unit is
available to operate according to the requirements of the control
signal.
When starting with an empty cylinder, the VAPANET
programme feeds water in until the water reaches the bottom
float switch, when the contactor(s) switch on powering the
elements. Thereafter the VAPANET system will continuously
monitor and control the conductivity by adjusting the amount of
water drained and fed into the cylinder.
2.0.4     Features of VAPANET Resistance Heater Unit
The VAPANET system of control is designed to adjust the
function to keep the unit operating in the face of changing water
quality in the cylinder and changing electrode condition even if,
in an adverse operational circumstance, this results in some
reduction in output while the situation exists.
Overtemperature protection.
Should the water supply and the float switch fail, an over
temperature cut-out is fitted to the top of the cylinder. If this
operates, the contactor will open, removing the power to the
elements. This cut out must be manually re-set, by pressing the
small button between the electrical connections. THIS SHOULD
ONLY BE DONE ONCE THE CYLINDER HAS BEEN INSPECTED AND
THE FAULT(S) RECTIFIED.
Foaming protection *
In particular, the VAPANET is designed to prevent the onset of
foaming and to introduce corrective drainage to keep the unit
working.
*Not applicable to units fed with de-ionised/de-mineralised water.

2.1      Service Advice
After a pre-determined time an alarm warning –
together with an alpha-numeric message – will be
displayed, warning that the cylinder should be                           Fig 1
inspected an cleaned as necessary.
Once this signal has occurred, the following service
routine should be undertaken as soon as possible. On
completion of the service, the service interval timer
will be reset, and there will be an opportunity to adjust
the service interval, if the service reveals that the
interval was inappropriate for the operating
conditions.
Service Advice Routine

2.1.1    Cylinder Inspection.
(See figs 1 - 4)
1 ENSURE THAT THE UNIT IS ISOLATED FROM
  THE POWER SUPPLY. Then remove the power                                Fig 2
  supply plug from the fixed socket.
2 Lift cylinder until the bottom (ø 22 mm) spigot is
   clear of the feed/drain manifold.NB it may be
   necessary to remove the steam hose from the
   cylinder, (top) steam outlet spigot, to achieve this.
3 Bring the base of the cylinder forward then allow the
   cylinder to rest on the cylinder support ring, then
   remove the cylinder.
4 Undo the securing latches, remove the clamping
  ring and lower cylinder casing.
5 Empty any loose scale from the lower casing, and
   clean as necessary.                                                     Fig 3
6 Inspect the elements, for excessive scale build-up
   or damage, and clean/ replace as required -
   Should it be necessary to replace elements,
   ensure that they are replaced with the same type
   and power. Please also ensure that the integral
   cables are re-connected exactly as the original.
   When disconnecting an element, please note
   the points of disconnection.

7 With the lower cylinder casing removed, and access
   to the float chamber improved remove the float
   chamber by unclipping it from the back panel and
   open the housing by removing the two plastic clips
   (use a screwdriver to lever these off) & pulling it
   apart (see fig 4).
8 Inspect the float switches, and clean/de-scale as
   necessary. A build up of scale can prevent correct
   operation of the switches, which - in turn - will lead
   to operational problems with the unit.

9 Re-assemble cylinder by repeating the above steps
  in reverse. To ensure that the cylinder seals
  correctly, ensure that the first four clamps that are
  tightened, are those at the four quadrants. I.e.
  tighten one clamp then tighten the one
  diametrically opposite. Then tighten one at
                    o
  approximately 90 to them and then tighten the
  one diametrically opposite. Finally, tighten any               Fig 4
  remaining clamps.

General cleaning and maintenance of the component parts
of the Vapac are recommended at intervals of about one
year, but this is largely dependent upon the frequency of its
use and the quality of the water supply. Where the Vapac is
part of an air-conditioning system being serviced regularly,
the Vapac should be inspected at the same time.                              2) Remove the two screws

At the end of the initialisation process, the LEDs will flash Green, Red, Amber
  repeatedly for 10 seconds to check that the LEDs are operation correctly.
Remedy:

      1       Check that UCP1 is fitted to plug fitted to CR4 pins 7 & 8 for units with Alpha-numeric
              display or fitted to configuration PCB part number 1150634, which is fitted to CR4 if no
              display is fitted (see section 1.5.3 of manual for more details). Ensure that good electrical
              contact is made in each case.

      2       Check that the jumpers J1 & J2 on the configuration PCB are correctly fitted, to select the
              site water quality and site control signal (see section 1.5.3 of the manual).

      3       Enter “Set-up unit”, enter the “control signal” type and “site voltage”, see Alpha-numeric
              display module operating manual.

      4       Once the unit has been “set-up” press ok at the prompt “Apply changes are you sure *?*”
              when the unit will exit this state.

      5       Check that the jumper J2 (on the configuration PCB) is correctly fitted, selecting the
              correct site water type (see section 1.3.1 of the “Installation, Operation & Maintenance
              Manual”).

                1 second period


1& 3          Fault stop: Once the problem has been cleared the fault can be re-set by one of the
              following procedures.
              i) Units fitted with an Alpha-numeric display: Power the unit right off, using the local
              isolator (not the unit on/off switch), waiting ten seconds, then re-applying power. When the
              message “Cylinder x drain fault” is once again displayed press the o.k. button, and the unit
              will revert back to it’s operational state.
              ii) Units not fitted with a display: Power the unit right off, using the local isolator (not the
              unit on/off switch), waiting ten seconds, then re-applying power. When the constant amber
              “drain fault” indication is showing, press the unit “fault reset” button, which is located on the
              fascia above the “Vapac” Logo.

2             High Temperature Fault: When the cylinder has cooled down, investigate the reason for the
              “over temperature” condition, paying particular attention to the feed water supply. Manually
              drain the cylinder, and carry out a cylinder inspection (see section 2.1.1 of the “Installation,
              Operation & Maintenance manual”). When complete, reset the high temperature cut-out on
              top of the cylinder and re-start the unit.

4             Service Interval Expired: Will be seen if the unit has run for a period exceeding the service
              interval, which will depend on the quality of the site water supply (see table below).

                              Water Type                      Service Interval
                                                              Hours
                              De-min / De-ionised             5000
                              Softened                        2500
                              Pot. Low                        2500

                              Pot. High                       500


If this indication is seen the cylinder should be inspected as soon as possible

              If it not convenient to carry out this inspection immediately it is possible to postpone
              it for a short time.

To Postpone the Sevice:
          Press the reset button once: The appropriate cylinder LED will change to constant “amber”
          and the external alarm will be reset, allowing the unit to continue to run without an external
          alarm for 168 hours run time.
                                                     25



             When the alarm is repeated, it should be serviced immediately – and not postponed
             further.

To Service the unit:
            Press the reset button:
            This will cause the appropriate LED to change to constant “amber”, the external alarm to be
            reset.
            Press the service button again: (this should be within ten seconds of the first push).
            This will cause a “service routine” to be implemented. Once this is complete,
            Isolate the electrical supply:
            Inspect the cylinder: As described in the maintenance section of the operating and
            maintenance manual.
            Clean the cylinder: As described in the maintenance section of the operating and
            maintenance manual.
            Power up the unit:
            Press the reset button:
            This will cause the appropriate cylinder LED will change to constant “amber” and the external
            alarm will be reset, allowing the unit to continue to run without an external alarm for a further
            168 run hours..
            Press the reset button again: (this should be within ten seconds of the first push).
             This will reset all the relevant timers including the hours run timer.

             NB if the button is not pressed a second time then the alarm will only be postponed,
             and will quickly return.

5            Event in Progress: This is a transitional state while the unit is actually performing a
             particular routine. The LED indication is for information only and requires no user
             intervention.

6            Event Completed: If one of the above conditions have been implemented, when it has been
             completed, the unit by default will continue to run, however it is possible to change this to
             “stop” (via a display either fitted or hand held) if this is the case this condition will be
             exhibited, and the unit will not run until the condition has been reset, by either:
             i) Units fitted with an Alpha-numeric display: Power the unit right off, using the local
                 isolator (not the unit on/off switch), waiting ten seconds, then re-applying power. When
                 the message “event complete” is once again displayed press the o.k. button, and the unit
                 will revert back to it’s operational state.
             ii) Units not fitted with a display: Power the unit right off, using the local isolator (not the
                 unit on/off switch), waiting ten seconds, then re-applying power. When the constant green
                 “event complete” indication is showing, press the unit “fault reset” button, which is located
                 on the fascia above the “Vapac” Logo.

7            Constant output:
             i) Units fitted with an Alpha-numeric display: This is another transitional state, and
                   once the “constant output period” has expired, the unit will revert to normal “controlled”
                   operation. The LED indication will automatically revert to the cylinder’s “current state”.
             ii) Units not fitted with a display: Once the testing of the unit is complete, the jumper J1
                 on the configuration PCB should be removed from the full output position and returned to
                 its normal operating position.

3.5      Other Options
All selectable via a display (either Hard Wired or Hand held)
Feed With Drain
Used to lower the temperature of the drain water.
Frost Protectiion
When this is activated the unit will operate, at a preset demand level, if the temperature surrounding the unit falls
below a preset level, to prevent the pipework from freezing.
It is enabled by setting “frost demand” (via keypad/display) to >0 (it I disabled by setting “frost demand” to 0).
However the unit will not operate unless “frost demand” is set above the unit minimum demand level. Minimum
demand level for LR units is 21% and for LRP units it is 10%.
Frost demand is fully adjustable between 0 & 50%.
Timed Drain down.
Used to drain all the water from the cylinder if the unit remains on standby for longer than a preset (but adjustable)
time period.
For information on setting these options please see the display manual.

                                   The following check should be carried out by a competent electrician
Equipment needed                   -   An AC Voltmeter, multi-meter set to full AC line voltage or suitable voltage test
                                       instrument.

Procedure                          -           Remove access panels from both the steam cylinder and electrical compartments
                                   -           Ensure that the humidifier has an operational level of water in the cylinder. Switch
                                               unit on and check that the display indicates “Vapac on line”.
                                   -           Apply the voltmeter, set to the ful line Voltage, across the output terminals of the
                                               SSR being tested (i.e. the two terminals carrying the cabling to the elements).

                                   Correct Voltmeter Response – oscillating between full and near zero Voltage.

                                   If Voltmeter reads a constant near zero Volts, Check:
                                   a) That the unit is not feeding water – if it is, wait until the feed valve closes and then
                                        re-check. (reason the SSR will hold closed while the feed valve is open).
                                   b) That the control PCB is giving the correct pulsed D.C. signal (approx 5V D.C.) to the
                                        SSR control input terminals.

SSR Replacement                    A faulty SSR should be replaced with an SSR of the same (or higher) Voltage and
                                   amperage rating. Disconnect the unit from the electrical supply. Disconnect the
                                   SSR and undo the mounting screws. The SSR is bedded in thermal compound
                                   to assist heat transfer – it is important that this is cleaned off, and a layer fresh
                                   compound placed under the replacement SSR. When it is secured in position.
                                   Reconnect the SSR, reconnect the electrical supply and check the SSR
                                   function as above before replacing the access panels.

                                   Note: Use proprietary thread locking compound on the line voltage
                                                                                                                                                                        28
