ILL1615-A
Turn on the mains water supply to the cooler.
Turn the cooler on at the controller, in “COOL” mode.
Adjust set temperature slider / fan speed buttons to be close to
current room temperature so that fan speed remains low.
Isolate power to the cooler electronics and disconnect the
pump, making sure the plug is kept away from any water. Turn
the power back on.

SETTING THE WATER LEVEL
ILL1370-B
Allow the pan (reservoir) to fill with water. The float valve will
eventually stop the water from entering the cooler. Wait for this
to happen and check the water level.
If the level is too high rotate the float clockwise. Drain some water
from the pan and allow it to refill to the new set point. If too low
rotate the float in an anti-clockwise direction.
For EXVQ models the correct water level is approximately 13/64”
(5mm) above the surface of the pan (reservoir) the float valve is
mounted on.
COMMISSIONING
Fault Code 01 (1 Red Flash) = Communication Failure
•
Ensure wall control cable is fitted correctly.
•
Check the wall control cable is in good condition.
Fault Code 02 (2 Red Flashes) = Failure to detect
water at probes within 8 minutes
•
Ensure water pressure is sufficient to fill and maintain the pan
(reservoir) to specified level within 8 minutes.
• In areas of hard or polluted water, blockage of the strainer/
filter in the water inlet solenoid valve may restrict water flow.
•
Water level set too low. For Breezair coolers the water level
should be set to 13/64” (5mm) above the float valve base.
•
Ensure probe plug is properly connected.
• Plug connections at electronic module are upside down or
misaligned.
•
Water too pure for the probes to sense water is present.
• Pressure build up in pipes can lock up the solenoid valve
when a non-return isolation valve is used in the water supply
line. It is recommended to use a ball valve, i.e. NOT a non-
return type of shut off valve.
• Check drain valve is closing and not cycling due to debris
being caught under drain valve washer.
Fault Code 04 (4 Red Flashes) = Failure to clear
probes during drain within 4 minutes
• Check the drain valve opens and water drains from the pan
(reservoir), with nothing obstructing the outflow of water. (e.g.
drain hose kinked)
•
Excessive drain hose lengths or bends cause air locking and
won’t allow water to drain.
• Build up of foreign material in drain hose not allowing water to
drain away correctly.
•
Screws used to fix drain hoses to drain adaptors restricting
water from draining from pan (reservoir).
•
Drain valve has failed to open when drain was initiated.
•
Inlet water solenoid not shutting off water when the drain is
open.
•
Water will only flow one way through the inlet water solenoid
valve. Therefore, it must be installed correctly. Directional
arrow must be pointing towards the float valve assembly. If
not, water will not shut off. (Directional arrow can be found on
the bottom of the solenoid valve body).
•
Debris interfering with water sensor probes.
•
Probes not clipped onto mounting brackets correctly.
•
Check cooler is level and water drains quickly.
