Problem
Cause / Solution
1. The ON/OFF power switch is set to
I (ON), and the POWER ON (GREEN)
lamp is not illuminated.
1.1 The power cord is not plugged into the power
receptacle.
Plug the power cord into the receptacle.
1.2 The disconnect power switch is not set to ON
or there is no power available to the disconnect
power switch box.
Turn on the power at the main power panel or at
the disconnect power switch box.
2. The POWER ON (GREEN), LOW GAS
PRESSURE RANGE (YELLOW) is
flashing and FAULT (RED) lamps are
illuminated.
2.1 The gas supply is turned OFF or not connected
to the power supply.
Check that the gas is turned on and is connected
to the power supply.
2.2 The incoming gas pressure is too low.
Set incoming gas pressure to 90-120 psig / 6.2-8.3
bar. Check that there are no leaks in the gas
supply line.
2.3 Output gas pressure is set too low for selected
mode.
Adjust gas pressure. See page 4-6 (item 3) for
pressure settings.
3. The POWER ON, LINE VOLTAGE
RANGE (YELLOW) and FAULT (RED)
lamps are illuminated.
3.1 Line voltage is too low, too high, or a phase
(CE system only) is missing.
Have a qualified technician check incoming power.
4. The POWER ON (GREEN),
TEMPERATURE (YELLOW) and
FAULT (RED) lamps are illuminated.
4.1 One of the internal thermostat switches has
opened due to overheating or extremely low
temperature.
Leave the power supply on to allow the fan to cool
the power supply (overheating). Move the power
supply to a warm location (extreme cold).
Note: Fan on/off is automatic. Fan may not
be in operation when power is ON.
