Turn on the cooling water supply and check for
leaks.
If any leaks appear, stop the test and fix the prob-
lem before continuing. The cooling water must be at least
25 PSI or the unit will not function. The LOW WATER
PRESSURE light will come on when power is applied.
The light goes off when the pressure is correct.
Apply power to the unit.
◆
Indicator lights on the control panel blink green, then
red, to test operation of the LEDs.
◆
Setpoint and actual windows will display for
three seconds, followed by the software version. The
windows then display the factory default setpoint of
100° F and the actual temperature.
Check the rotation of the pump.
Remove the top
access panel and the pump motor drip cover. Verify that
the pump rotation matches the direction indicated on the
rotation sticker on top of the pump.
NOTE:
If the rotation is incorrect, stop the test and
disconnect power to the unit. Open the electrical
enclosure and switch any two of the three power
source wires on the terminal block. Return to Step 2
and check rotation again.
Replace the drip cover and top access panel.
Press the RUN key to start the unit.
If everything is working correctly:
◆
The RUN/STOP light turns green.
◆
The unit initiates a 60-second venting sequence.
Cooling and venting valves are active for 60 seconds.
The pump is active for the final 30 seconds. Indicator
lights will energize when the device is active.
◆
Normal operation begins. The heater turns on if the
actual temperature is below setpoint. The cooling valve
is active if the actual temperature is above setpoint.
The test is over. Proceed to initial setup if the unit operated
normally; refer to the
T
ROUBLESHOOTING
section if it did not.
