5. OPERATION
5.1. Installation
The refrigerator should not be installed in the vicinity of radiators or other sources of heat.
Optimum cooling performance is generally obtained at ambient temperatures of +16 °C to
+32 °C (+60 °F to 90 °F).
Fixed bolts on the rear of the unit insure that sufficient distance will be maintained to adjacent
walls for proper air circulation.
Make sure that no objects obstruct circulation behind the refrigerator.
Before operating the unit after transport, wait about one hour after setting it up. This will allow
any oil that has accumulated laterally during transport to flow back down thus ensuring
maximum cooling performance of the compressor.
Stable mounting is attained by turning one or more of the height-adjusting feet underneath
the appliance.
The place of installation should be large enough and provide sufficient air ventilation to
ensure the room does not warm up excessively because of the heat the instrument rejects to
the environment.
The standard EN 378 prescribes a certain room space to be available for each kg of
refrigerant.
Please see type label for amount of refrigerant.
> For 0.0011 kg of refrigerant R600a, 1 m
3
of space is required.
The door handle and the locking mechanism with key are enclosed with the KRC 180 unit.
Change the door opening side (part 6.) if the right side is not convenient, and mount the door
handle.

Power connection / Switching On
Caution :
Only connect the unit to a power socket with earthing contact (PE – protective
earth)!
The power supply plug serves as safe disconnecting device from the line and
must be always easily accessible.
Never operate equipment with damaged mains power cables.
Regularly check the mains power cables for material defects (e.g. for cracks).
We disclaim all liability for damage caused by incorrect line voltages!
Compare the intended mains voltage with the voltage specification on the identification plate.
Deviations of +10 % / -10 % are permissible.
Switching on: connect the unit to a power socket
