Care and maintenance
Regular care and observation of some basic points
will ensure trouble-free operation and a long
service life.
DANGER!
Prior to performing any work, ensure the equip-
ment is disconnected from the voltage supply
and secured to prevent accidental switch-on!
Care
n
Ensure the unit is protected against dirt, mould
and other deposits.
n
Only clean the unit using a damp cloth. Do not
use any caustic, abrasive or solvent-based
cleaning products. Do not use a jet of water.
n
Clean the fins on the unit prior to long shut-
down periods.
Maintenance
n
It is recommended that you take out a mainte-
nance contract with an annual service from an
appropriate specialist firm.
This enables you to ensure the operational reli-
ability of the plant at all times!
n
For systems which operate year-round (e.g. in
server rooms), the maintenance intervals must
be reduced accordingly.
NOTICE!
Statutory regulations require an annual leak
test for the cooling cycle dependant on the
refrigerant quantity. Inspection and documenta-
tion of the work performed is to be carried out
by specialist technicians.
