REFITTING THE PAD FRAMES
Refit the pad frames by locating the bottom edge in the tank
groove, then push the top into the lid.
TESTING THE PUMP
Test the pump by turning the cooler on at the MagIQtouch
Controller, in “COOL” mode. Check that water is evenly
distributed to all pads.
Note!
If the cooler has not been on before it will run a “Pre-Wet”
routine where the pump will operate to saturate the pads.
This cycle takes 2 minutes, then the fan will start automatically.
TESTING THE DRAIN VALVE (WHERE FITTED)
Select the “SETTINGS” mode on the MagIQtouch Controller
and select the “COOLER” sub-heading.
Select the “MANUAL DRAIN” option to operate and test the
drain valve.
COMMISSIONING THE COOLER
TEST OPERATION
Check that the green light on the electronics module is on and
double flashing every 2 seconds. This indicates that power is
connected to the electronics module.
Important!
Ensure the flexible splash protection cover is put
back in place.
FAULT CODES INDICATED BY LED’s ON
THE ELECTRONICS MODULE
Fault Code 01 (1 Red Flash) = Communication Failure.
•
Ensure the wall control cable is fitted correctly.
• Check that 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 tank
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 5mm / 3/16” below the float valve base.
• Ensure probe plug is properly connected.
• Plug connections at electronic module 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 (where drain valve fitted).
• Check the drain valve opens and water drains from the tank,
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 tank.
• 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.
Fault Code 07 (7 Red Flashes) = Incorrect supply frequency
(Hz).
This fault will only be seen when the mains power supply
frequency deviates from normal frequency by more than 8%.
Mains power supply frequency should be 50 or 60Hz. See
nameplate for exact data for this air cooler. Petrol/gasoline
generators are the most likely cause of this type of fault. This
typically will not occur on mains power supplies.
