1 Assembly information
1.1 Connecting the appliance to an
external unit or to a central cooling
system
Note
You can only connect specially prepared version appli‐"r"
ances, such as FRTSrg, FFTRrg, to an external unit.
CAUTION
Health hazard due to escaping refrigerant/nitrogen!
Respiratory problems.
uMake sure that only trained refrigeration engineers
connect the appliance to an external unit or a central
cooling system.
CAUTION
Health hazard due to live parts!
Electric shock.
uBefore starting assembly work: Disconnect the power
plug.
1.2 Components
The following thermostatic expansion valves are installed:
-Cooler: Danfoss Thermostatic Expansion Valve TN2
068Z3384.
-Freezer: Danfoss Thermostatic Expansion Valve TN2
068Z3384.

1.4 Assembly procedure
CAUTION
Health hazard due to escaping refrigerant/nitrogen!
Respiratory problems.
uOpen the refrigerant line carefully.
CAUTION
Damage to the appliance due to condensate!
Corrosion of components.
uDo not shorten the refrigerant line in the insulation.
uInstall the extended refrigerant line in an insulating tube.
Note
Reduction in cooling capacity.
uIf you extend the refrigerant line: do not reduce the inner
diameter of the pipe.
uInstall the refrigerant lines that are supplied on the rear
side of the appliance toward the cooling unit or the
building refrigerant lines according to the structural
conditions.
- ø Intake line 10 x 0.7 mm
- ø Pressure line 6 x 0.7 mm
The appliances are equipped with a refrigerant valve (stop
valve) that is already connected with the electronics. The
temperature is regulated by opening and closing the valve.
The thermostatic expansion valve is located in the motor
compartment.
uSet overheating on the valve if required. The works
setting is 4K. 1 clockwise revolution corresponds to 2K
higher overheating.
Assembly information
2 * Depending on model and options
uA connection must be installed in order to evacuate the
system. Evacuation is only possible on the pressure side
as the passage through the valve is in this direction. It is
not permissible to evacuate only on the intake side, as in
this case the line from the stop valve to the building
connection point would not be evacuated.
uIf you have released the solenoid valve coil, then you can
open the valve with a suitable ring magnet. This can be
noticed by a clicking sound.
uIn order to avoid vibration noise and breaks in the refrig‐
erant lines, they must be installed accordingly.
The system was already tested for leaks in the factory.
Leaks can result from bending the pipes and adjusting the
overheating.
uSolder joints must be checked for leaks.
uMake sure there are no leaks near the pipe lead-through.
1.5 Electrical connection
uConnect the appliance to the mains.
Note
The coolant unit cannot be controlled using the appliance
user interface as it does not have an interface for this.
1.6 Tests and checks
uLeak check: Check all solder joints and screw connec‐
tions for leaks.
uFunctional test: Check of all operating conditions
(cooling, defrosting) in consideration of the description of
the operating and control elements according to the user
instructions.
wMalfunctions are signaled by various alarms. A failure of
the central cooling system is signaled by a temperature
alarm.
