Preparation for installation
!
CAUTION!
z Carefully read these installation instructions and the installation manuals
provided in each case (driving cooling, parking cooling, engine installa-
tion kit etc.).
z Protect your eyes! Eye protection must be worn at all times when filling and
evacuating refrigerant!
z Wear protective clothing! Refrigerant must not come into contact with skin.
➤ Check that the Frigo cooling system is complete using the parts lists.
➤ Only remove the sealing caps from the compressor, evaporator, condenser and refriger-
ant lines immediately prior to installation of the parts concerned, as only in this way can
you ensure the system is kept free of moisture and dust.
➤ Before connecting a refrigerant line, add a few drops of refrigerant oil to the O-ring seat
and the union nut.
3.3
Handling cables and hose lines
!
WARNING!
Improper changes or additions to and in the vehicle's electrical and electronic
systems can result in the impairment of individual functions. This can lead to
the failure of vehicle components or vehicle safety equipment and result in
accidents causing personal injury or damage to the vehicle!
z Use ductwork or cable ducts if it is necessary to lay cables through sharp-edged panels
or floors.
z Make sure that all retrofit drilling and/or ducting work performed has a watertight
assembly.
z Complete the electrical wiring so that damage from sharp-edged vehicle components is
avoided.
z Do not lay loose or bent cables next to electrically conductive materials (metal).
z Attach and lay the cables in such a manner that they cannot be damaged.
z Never lay power supply lines (battery leads) in the vicinity of signal or control wires.
z Prior to and during drilling, note the location of existing cable harnesses, cables and
other components.
z Treat the parts with a corrosion inhibitor immediately after performing drilling or cutting
work.
z Cover the plastic piping and brake hoses before drilling; remove them if necessary.
z Lay the electrical cables so that they are a distance of at least 15 mm away from rotating
parts and at least 150 mm away from parts of the vehicle which become very hot.
z Do not attach any cables, electrical cables or hose lines onto the braking system hoses.
