Error Codes On The Display; Defrost Water - Gram SF 930 Bedienungsanleitung

Error codes on the display

F1 If code F1 is displayed it means that the cabinet temperature sensor is defective
and service assistance should be requested. In the meantime the cabinet itself
will maintain the set temperature by the memory of the controller.
F2 If the display alternates between temperature and error code F2 there are
problems with the temperature sensor on the evaporator. This has no effect on
the operation of the cabinet, but the sensor should be replaced as soon as
possible. Request service assistance.
F3/F4 If the display alternates between temperature and error code F3/F4 there are
problems with the temperature sensor on the condenser. This has no effect on
the operation of the cabinet, but the sensor should be replaced as soon as
possible. Request service assistance.
NOTE! Applies only to cabinets with built-in compressor.
F7 Indicates that the condenser temperature is too high. Switch off the cabinet at
the mains and see whether the condenser has been covered. If this is not the
case, the high temperature might be the result of dirt on the condenser. The
condenser can be cleaned with a brush or vacuum cleaner. Switch on the
cabinet again. After an hour, the cabinet should run normally. If the dots begins
flashing again, request service assistance.
NOTE! Applies only to cabinets with built-in compressor.
- o - The door is open.

Defrost water

The cabinet expels defrost water during defrosting, which is led into a tray on the backside
of the cabinet (see Fig. 8).
A re-evaporation pipe from the refrigeration system, and an electrical heating element,
placed in the tray, re-evaporates the water.
Some models are equipped with a condensate pump, which pumps the water up into a
tray in the compressor compartment, where it is re-evaporated..
It is recommended to clean the tray at least once a year. Remember to disconnect
the cabinet before cleaning.
Be careful not to damage the re-evaporation pipe and heating element during
cleaning.
