SERVICE PROCEDURES
220DS 4 pipe Control Unit
The following section outlines the steps and
procedures to follow if there is a suspected fault in
the Control Unit.
Malfunction of the Control Unit may be due to the failure of one
of the replaceable electrical components of the Control Unit,
including the compressor, print circuit board and timing motor
rotary valve.
Any fault or damage to the product that is not
discussed in these Service Procedures is deemed
a non serviceable issue. The faulty product must
be returned to the Manufacturer for repair or
replacement.
Alternatively, a lack or loss of system pressure can be attributed
to a variety of causes, including an incorrectly attached CPR Tag;
a loosely connected or leaking Air Cell; leaking Air Pipe; or faulty
fuse. Insufficient system pressure is identified when the Alarm
LED flashes, and the corresponding Pressure Setting alarm
signals display.
If a repair seems unmanageable or the issue falls
outside the scope of serviceable repairs,
please return the Control Unit to the Manufacturer.
Should the Control Unit fail to operate, or system pressure fail to
reach normal operating status, please follow the steps below to
isolate the cause of the problem and make the relevant repair.
Please note that this is a generic service manual
which is applicable for several different models. Thus
the products used in the pictures may differ from the
product shown below.
