2.5. Replacing the Thermostat
Uprights
Dismount the phial tube and straighten out the phial. Draw off
the insulation, if any, around the phial. The phial can now be
drawn out of the lead-in pipe from the back of the unit.
After the plug has been removed from the socket, remove the
cover for the top panel and the panel box.
Remove the thermostat knob, nut and thermostat wiring.
Install the new thermostat in reverse order.
Chest freezers
The procedure for replacing the thermostat can readily be seen
on chest units. Ensure that the phial is inserted as far as
possible inside the phial tube.
Installing the Thermostat Phial
Positioning of the Thermostat Phial in NFG 307 till Serial
No. 501-----
In order to ensure the proper functioning of the thermostat 90
mm of the free end of the capillary tube is to serve as
thermostat phial.
In case of failing thermostat functioning and a possible re-
placement of the thermostat, be sure that the phial part is
placed sufficiently far into the cabinet. This can be done
visually by loosening the screws holding the evaporator box
against the top of the inner cabinet and lowering the
evaporator
box so that the phial can be seen at the back of the cabinet.
