Dometic FJ 1700 Installation Manual page 10

Installation
• Make sure no combustible objects are stored or installed near the air outlet. A
distance of at least 50 cm should be kept.
• Make sure that there are no objects within the vehicle which could obstruct the
attachment of the air outlet unit or the cooled air from flowing through the
swivelling air distribution nozzles.
• For safety reasons, note the location of existing wiring harnesses, wires and other
components within the installation area, in particular those which are not visible,
when installing the roof air conditioner (when drilling or screwing etc.).
• The device shall be installed, operated and stored in a room with a floor larger
2
than 4 m .
Note on electrical system
• Only a qualified electrician should connect the roof air conditioner to the
electrical power.
• Check that the voltage specification on the type plate is the same as that of the
power supply.
• If the lighting should also be switched on without a 230 V voltage supply, make
sure that there is a 12 Vg power supply line from the battery to the roof air
conditioner.
• Do not lay the 230 V mains cable and the 12/24 Vg cable together in the same
cable duct.
• Do not lay cables which are loose or bent next to electrically conductive material
(metal).
• Install an all-pole switch with a contact opening width of at least 3 mm on the
installation side.
• If the appliance is powered by the mains, ensure that the 230 V voltage supply
has a residual current circuit breaker.
• Make sure that the grounding cable of the air conditioner is connected to the
vehicle's grounding system.
There are two ways of installing the roof air conditioner:
• Making a new opening (chapter "Making a new opening" on page 11). In this
case the opening must be reinforced by an appropriate frame.
• Using the existing roof hatch openings (ventilation hatch) in the vehicle (chapter
"Installing in a roof hatch opening already provided" on page 11).
