Frigo
z Lay all hose lines and electrical cables ensuring they are free of any mechanical loads.
z Attach the cable set with cable binders and/or hose clips.
z Join the compact plug connections so that snap-in points are fixed.
z Make sure that the rubber seals for the cables and plug housing are present when
assembling the watertight plug housing.
z Protect the plug connections that are not watertight in those areas where there is a
strong risk of splashing (engine compartment, underbody) with additional protective
wax spray, insulating tape or similar. Corrosion on the plug connections can lead to the
failure of the cooling system.
z Ensure that retrofit fuse housings are installed outside of the area exposed to splashing
water. Observe a minimum distance of 30 mm to the liquid circuits. A distance of 300
mm must be observed between the fuse housings and flammable liquids (petrol filter,
tank, etc.).
z Install the fuse housings as close as possible to the battery.
z Do not connect any additional power consuming devices to the fuses used.
z Do not connect any additional cables (e.g. insulation displacement terminations) to the
existing cable lines.

Instructions following installation
z Carry out leak detection using a UV leak detection lamp so that leaks in the Frigo cooling
system can be avoided.
z Check the efficient functioning of all cooling system components.
z Make sure that the cooling system components do not create a risk of injury for vehicle
occupants (e.g. due to sharp edges) and do not impair the function of safety features.
z Always carry out a function test after the installation of the cooling system.
z Never change the parameter values in the control unit that are used for the basic and
backup functions of the cooling system.
z Ensure that the finishing work for the heat insulated interior in the vehicle is in perfect
condition. If this is not the case, contact the person responsible for the insulation finish-
ing work.
