ACR Fault
Finding Guide
First check if the condensate water level probe in the ACR tank is dirty and
needs cleaning (a dirty probe may either fail to detect water, or give a false
indication of water) clean if required.
Check the Finder Level Control unit sensitivity range adjustment is set to 75k
.
If the sensitivity is set too low, the Finder Level Control unit may not detect the
condensate water and wo
n’t switch on the ACR element. If the sensitivity is set
too high, the Finder Level Control unit may get a false indication of the
condensate water and switch on the ACR element without water present.
Fault:
ACR element is on continuously when no condensate water is present.
Test:
Check if the Finder Level Control unit is faulty by disconnecting the probe
wire from terminal B1 on the Finder Level Control unit. With the cabinet power
turned on and after waiting 10 seconds, check for 230V across terminals 11 and
14. If 230v is not present across terminals 11 & 14, replace the Finder Level
Control unit.
Fault:
ACR element does not heat even though condensate water is present
and touching the water level probe.
Test:
First check the ACR unit has a 230V power supply.
Next, check the Finder Level Control unit water sensing circuit by short-
circuiting the level sensor terminals B1 & B3. Turn the cabinet power on and
wait 10 seconds and then check if the ACR element heats. If the element heats,
check for an open circuit in the water sensing probe circuit and clean the probe.
If the element does not heat, turn the cabinet power off and take the element
wire out of terminal 11 and wire into terminal 14 on the Finder Level Control
unit. Turn the cabinet power on and wait 10 seconds and then check if the ACR
element heats. If the element heats, replace the Finder Level Control Unit. If the
element does not heat replace the element and Therm-O-Disc assembly.
Note:
The element and Therm-O-Disc are supplied as a complete assembly.
Access to
Condenser
Radiator and
Control Gear
To access the condenser
radiator and control gear,
simply pull the louver panel
forward, to disengage the
magnetic catches.
It is vital that the radiator is
kept clean. If air flow is
restricted, refrigeration
efficiency will be poor.
The radiator fins must be
regularly cleaned, using
compressed air. Do this at least every six months, or more often if
needed.
