The information described below are useful for the service staff.
The faults that require the intervention of a refrigeration
engineer must be carried out only by specialized staff. Follow all electrical legislation when working on the unit based on valid
laws of the countries were the unit is placed.
Chiller
Problem
Cause
Possible corrective Action
The unit does not start
up
No supply voltage
Check the supply main voltage line
Not working thermostat
Inspect the connection, check and correct the parameter settings and if there
is no fault, replace the thermostat,
The compressor protector (KLIXON)
has switched off
Important:
After the shut down of the compressor, the resetting time will
depending on the environment of the compressor: In a hot closed
environment it will be 2 hours, in ventilated 1 hour.
Note:
The compressors are protected against high temperatures and
currents, with of an internal or external device (Klixon). The internal/external
device protects the compressor against the following situations:
overheating due to an inadequate cooling of the compressor motor.
Blocked compressor due to a high temperature of the motor or a high
current.
Loose connections which may cause high currents
It works, but does not
cool
There is not enough gas in the
equipment
Service by a refrigeration engineer
Faulty thermostatic valve
Service by a refrigeration engineer
Too high heat load
Possible wrong application, to be checked with our staff
Refrigerant Cycle is not working
Problem
Cause
Possible corrective Action
Switching of low
pressure switch
The unit works for short periods, it
stops and starts again after a while.
The causes are:
Low gas level in the equipment
Outlet line of the compressor is
blocked and more in detail:
satured dehydrating filter,
blocked thermostatic valve.
Service by a refrigeration engineer
Switching of the high
pressure switch
The unit does not work.
The causes are:
Dirty condenser
Clean the condenser with compressed air if it is full of dust, or use proper
solvents suitable to remove sludges.
