Fill Check Fault
The dual fill valves have been active for an extended period of time without the water
level rising in the float chamber. The unit will not operate without an accurate water level
reading. Fix the problem before restarting the unit.
Water supply problems.
– Make sure that the water supply line is open, and there is adequate flow and pressure.
Loose wiring, or clogged strainer in dual fill valves.
– Check the wiring to the float board and the dual fill valves.
– Check the strainer in the dual fill valves is not clogged – refer to
Valves and Drain Pump" on page 54
Drain pump running, or manual drain valve open.
– Visually check that the manual drain valve is closed, and the drain pump is not
running.
Floats may be stuck.
– Visually check that the different LEDs on the float board light up as the water level in
the float chamber changes. If necessary, clean the float chamber – refer to
.
Fill valve relay on the driver board not seated properly, or defective.
CAUTION!
Electro-static discharge damage to board.
– Check that LED3 (corresponding to REL4 for the high volume fill valve) and LED4
(corresponding to REL5 for the low volume fill valve) on the driver board light up when
the fill valves are supposed to be energized. If not, check the relay(s) is seated prop
-
erly on the driver board.
– Swap the relay(s) with another relay on the board to verify that it is working. Replace if
necessary.
Defective dual fill valves.
– Check for 24 VAC on the pins of the dual fill valves. If necessary, replace the dual fill
valves. Reconnect the wires correctly.
Scale build-up in the drain fitting.
– Clean the drain fitting, as described in
"Cleaning the Tank" on page 51

Blower Not
Operating
The identified blower is not operating, or registered a value below 500 rpm while being
energized. The unit is unsafe to operate with this fault condition. Fix the problem before
restarting the unit.
Loose connections.
– Check the PWM (pulse width modulation) and power connection to the blower.
Blower relay on driver board may be defective.
CAUTION!
Electro-static discharge damage to board.
– Visually check that LED7 (corresponding to relay REL8 for the blower) on the driver
board lights up when the blower is supposed to be energized. If LED7 does not light
up, the relay is faulty.
– Replace the driver board. Refer to the GS Spare Parts List.
Blower feedback signal may be missing.
– Restart the unit, and check the blower rpm in
in the control software. If
the rpm is low, contact your Condair representative.
Restrictions at blower, or damaged blower.
– Visually inspect the blower and blower inlet for restrictions.
– Visually inspect the blower impeller for damage. Order a replacement blower, if
necessary.
Main power to blower relay damaged.
– Visually inspect the connections between the main power.
– Visually inspect the blower relay for damage and replace if necessary.
Worn out blower.
– The blower speed may decrease due to wear. The blower is safe to operate, but the
output may be reduced. Order a replacement blower.
