ATTENTION:

1. As for cooling water, make sure to use the soft water or pure water,

     and the temperature of the cooling water should be lower than

     40℃(104○F).

2.   The induction coil is very important for satisfactory heating, so please

     consult us if you have any problem in design of your induction coil.




一、 INTRODUCTION

LED:
POWER LED---This red LED will be on to indicate the control power is OK.
OPERATING LED---This green LED will flash accompanying with pulsed buzzing
when the machine is working.
LACK OF WATER LED---This red LED will turn on accompanying with continuous
buzzing when enough water is not supplied or the temperature of cooling water is too
high.
OVER VOLTAGE LED---This red LED will turn on accompanying with continuous
buzzing if the input voltage is higher than 245V AC.

    indicate the heating time, there are not retaining and cooling period.
(2) When switching to “AUTO”, the three period of heating retaining and cooling will
    be processed automatically according to the time adjusted.

HEATING POWER ADJ KNOB---Either “MAN” or “AUTO”, the output oscillating
current during heating period can be adjusted by this knob.
RETAIN POWEE ADJ KNOB---Only at “AUTO” status, the output oscillating
current during retaining period can be adjusted by this knob.

TIME DISPLAY---To indicats the heating or retaining or cooling time.

CURRENT DISPLAY METER---To indicate the output oscillation current during
both the heating period and the retaining period, current range is from 200Ato 600A.

HEAT TIME ADJUST---To adjust the heating time period at “AUTO” atatus.
RETAIN TIME ADJUST---To adjust the retaining time period at “AUTO” atatus.
COOL TIME ADJUST---To adjust the cooling time period at “AUTO” atatus.

REMOTE CONTROL SOCKET---This tour pin socket can be connected with a

                                         5
remote control box , so the start and stop button function can be easily completed

四、 INSTALLATION
CONNECTING OF COOLING WATER SYSTEM
        City water or circulating water system can be used, but be sure the water is
clean and with a pressure of 0.05-0.3MPa and a flow of 3-8L/Min.
ELETRICAL CONNECTION
        GP-15 machine operates on a single phase AC 220V input, allowing voltage
change from 180Vto 245V AC, 6mm2 copper core wire should be used, and the input
power cables whould be connected to the power supply through fused disconnect
switch.
GROUNDING
        The frame of this machine should be grounded with 4mm2 copper core wire
for personnel safety.
