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

Ensure the unit is protected against dirt, mould

and other deposits.

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.

Clean the fins on the unit prior to long shut-

down periods.

Maintenance

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!

NOTICE!

Statutory regulations require a leak test for the

cooling cycle dependent on the refrigerant

capacity. Inspection and documentation of the

work performed is to be carried out by specialist

technicians.
