13.3 Maintenance generally
Disconnect the chiller from all electrical power supplies and secure
against inadvertent switching-on while carrying out maintenance.
There are hot components behind the covers.
When the covers are removed for maintenance or repair work, make
sure not to touch these components!
When working on the cooler, wear protective gloves, work clothing
and safety goggles.
Do not reach within the rnage of rotation of the fan blade. Danger of
injuries when the fan blade start to rotate. Before you open the front
cover, the plant must be switched off by means of the master switch
and must be secured against inadvertent switching on.
The level of the coolant is to be checked at regular intervals and if necessary the coolant (water-
glycol mixture, see “Use and function”) topped up. It is recommended that the bolt fixings of the
primary circuit be regularly checked for tightness. This applies in particular if the coolant is
frequently low.
13.4 Cleaning the metal air filter and condenser (optional)
The metal air filter is to be checked for dirt at regular intervals. Cleaning with compressed air is
sufficient for normal dirt contamination.
Dust is to be removed from the condenser fins from time to time. Careful brushing or cleaning
with compressed air is sufficient for normal dirt contamination. The maintenance interval depends
on the ambient conditions at the installation site.
Take care. The condenser fins are very delicate. Do not damage the
condenser fins while cleaning them.
When working on the condenser, wear protective gloves, work clothing
and safety goggles. Risk of injury on sharp ribs.
The filter mat may be replaced by instructed personnel only.
A soiled filter mat will cause the refrigerating capacity of the unit to
decrease. As a result of the additionally increasing power consumption
of the compressor, the efficiency of the plant / chiller will drop
considerably.
