8.2.1
Maintenance of the refrigeration unit
The refrigeration unit operates largely without maintenance. Depending on the ambient dust
conditions and the operating time, any dust on the heat exchanger (condenser) must be removed at
intervals on 2 weeks or longer. This is done after taking off the front grille. Brush off the condenser
and if necessary blow through with compressed air.
8.2.2
Note on repair and disposal
The refrigeration circuit is filled with a CFC-free refrigerant. Type and charging quantity are
indicated on the unit. Repair and disposal by a qualified refrigeration engineer only!
If the equipment does have to be returned to the factory, it may only be necessary to dismantle the
thermostat unit and return it.
☞
−
If the equipment has to be returned to the factory, please ensure that it is carefully
and properly packed. LAUDA accepts no responsibility for damage due to
unsatisfactory packing.
8.3 Ordering
spares
When ordering spares please quote instrument type and serial number from the rating label. This avoids
queries and supply of incorrect items.
We shall always be happy to deal with queries and to receive suggestions and criticism.
