1. Submittal
* For the items assigned to the Contractor(s) signing below, the checklist items are complete as marked and ready
for functional testing. The checklist items have been checked off only by parties having direct knowledge of the event.
*This checklist is submitted for approval for the TU list attached, subject to the attached list of outstanding items yet to be
completed. A Statement of Correction will be submitted upon deficiency correction. None of the outstanding items
preclude safe and reliable functional testing of other TU's.

3. Checkout Record
Prefunctional checklist items are to be completed on each TU as part of startup & initial checkout, preparatory to functional
testing. Further instructions and an explanation of each checklist item, by column number, are found below. See attached
sheets for actual checkout record. This checklist does not take the place of the manufacturer’s recommended checkout
and startup procedures or report. The installing contractor’s startup and checkout plan shall make reference to
incorporating this checklist or have it attached when submitting the plan to the commissioning agent for approval, prior to
execution.
Col. # CHECKOUT PROCEDURES AND KEY: (refers to column number of TU record)
1 Application and installation in conformance with mf'rs recommendations and job specs. Specified sound wrapping and joint
sealant installed.
2 Any high pressure ducting upstream has been leak and pressure tested, cleaned and approved prior to setting TU.
3 Model and tag checked against plans and equipment list. Tag or mark affixed.
4 Unit secured per manufacturer's recommendations, contract documents and seizmic requirements.
5 Unit has sufficient clearance to be serviced.
6 Inlet conditions OK: Smooth, round, straight duct for at least 3 duct diameters when possible and 2 diameters minimum for velocity
pressure sensor for flow readings and 3 to 5 diameters for single point electronic sensors, else airflow straighteners, OR per
manufacturer's recommendation.
7 All balancing devices have been provided in compliance with the contract documents.
8 Any hot or chilled water piping installation complete with valves tagged. Auto-flow control valves checked to ensure proper model.
9 Controls Hardware Check: a) Wiring checked to each point. b) Software pt. address input into box and checked for all points (zone temp.,
pressures for flow calcs, damper position, fan status, supply air temp., valve position, etc.). c) Release actuator clutch and verify free damper.
10 Controls Software Load. Power up unit and download approved software program.

11 Operational Check. a) Start air handler fans. b) Override space temp. to be 55F to simulate full heating. Verify that BAS flow sensors read
the maximum heating flow and minimum cooling flow for that box per box schedule. Verify proper opening of heating coil valve, if
applicable. c) Override space temp. to be 80F to simulate full cooling. Verify that BAS flow sensors read the maximum cooling flow and
minimum heating flow for that box per box schedule. Verify by observation, the proper closing of heating coil valve, if applicable. During the
above sequencing, if box is fan powered, verify no unusual sound or vibration and verify proper fan staging.
12 Sensor Calibrations. All Sensors: a) Verify that all sensor locations are appropriate and away from causes of erratic operation. Verify that
sensors with shielded cable, are grounded only at one end. b) For sensor pairs that are used to determine temperature or pressure
differences, make sure they are reading within 0.2F of each other for temperature and within a tolerance equal to 2% of the reading, of each
other, for pressure. Critical applications may be tighter. Sensor Without Transmitters: Make a reading with a calibrated test instrument
within 6 inches of the site sensor. Verify that the sensor reading (via the permanent thermostat, gage or BAS is within 0.5F for temps and
within 3% of design for pressures of the instrument- measured value. If not, install an offset in the BAS, calibrate or replace sensor.
** Fully document procedures 9-12 on a separate form for each terminal unit. The form should have a cell to record each check and
calibration for each sensor and BAS point, including initial and final values and max and min cfms. Other data may also be included (inlet
size, k factor, etc.). The above procedures are not a substitute for the manufacturer's recommended start-up and checkout procedures, but
are to be combined with them , as applicable.
13 All A/E punch list items related to this TU have been corrected.
14 The system has been balanced in accordance with required proceduresand the TAB has been approved for the AHU of this TU.
15 Required pipe cleaning to this unit, pipe flushing and pressure testing has been completed successfully.
16 Construction filter has been removed and final filter installed, if applicable.

3. Checkout Record
Prefunctional checklist items are to be completed as part of startup & initial checkout, preparatory to functional testing. Further
instructions and an explanation of each checklist item, by column number, are attached to the checklist. In each cell, enter the date the
check was completed. Footnote explanations as needed. Items that do not apply shall be noted with the reasons on this form (N/A = not
applicable, BO = by others). · If this form is not used for documenting, one of similar rigor shall be used. · Contractors assigned
responsibility for sections of the checklist shall be responsible to see that checklist items by their subcontractors are completed and
checked off. · “Contr.” column or abbreviations in brackets to the right of an item refer to the contractor responsible to verify completion
of this item. MC = mechanial contractor, SM = sheet metal, All = all contractors, CA = commissioning agent, CC = controls contractor,
