Before installation, find out (by consulting the manufacturer of the vehicle)
whether the construction is designed for the static weight and the loads of the air conditioner when the vehicle is in motion. The manufacturer of the roof air conditioner assumes no liability whatsoever.
The vehicle manufacturer may have already provided points where the opening for the installation of the roof air conditioner can be made without any risk of weakening the construction or cutting power cables.
Select a flat and sufficiently level area at the centre of the vehicle roof between two longitudinal sections for installation.
The roof inclination of the installation surface may not exceed 10°.
The roof air conditioner must be installed above 2 meters.
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 than 4 m2.

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. DometicFJ1700-FJ2000-FJ2200-FJ3200_INM_4445101815_EMEA16_202x-xx-xx.book Seite 10 Mittwoch, 13. Januar 2021 5:16 17 EN FreshJet Installation
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).

Making a new opening

See fig.3

➤ Select an area at the centre on the roof between two longitudinal supports.
➤ Mark the position and size of the opening using the template included in the packaging (A and B).

See fig.4

➤ Drill out the corners (A).
➤ Carefully cut out the opening on the roof using a keyhole saw or a similar tool (B). Make sure no electrical power cables are damaged.

See fig.5

➤ Before installation, check whether the roof hole needs reinforcing.
➤ Remove the foam according to the width of your reinforcing rails (not in scope of delivery) (A).
➤ Fit the reinforcing rails (B).

Installing in a roof hatch opening already provided

NOTE

Existing roof hatch openings in accordance with fig.3 are suitable for installing the roof air conditioner.
Dispose of all waste material, glue, silicone and seals separately. Observe the disposal guidelines.
The manufacturer only assumes liability for parts included in the scope of delivery. The validity of the warranty expires if the device is installed together with third-party parts.

See fig.6

➤ Remove all screws and fixtures of the existing roof hatch.
➤ Take out the roof hatch.

See fig.7

➤ Remove the sealant around the opening using a scraper or similar tool.

See fig.8
NOTICE! Damage hazard Observe the sealant manufacturer’s instructions.

➤ Seal the screw holes and recesses with a flexible non-hardening butyl sealing compound (e.g. SikaLastomer-710)

Laying the connecting cables

WARNING! Electrocution hazard Make sure there is no voltage at

electrically operated components before carrying out work on them.

The roof air conditioner must be connected to an electric circuit which is able to supply the required current (see Technical data in Operating Manual).

➤ Select the cross-section of the cable corresponding to the length:
– Length < 7.5 m: 1.5 mm²
– Length > 7.5 m: 2.5 mm²

See fig.9
➤ Make an opening on one side in order r to feed through the electrical power
supply cable.
➤ Feed the 230 Vw cable through the opening into the vehicle interior. If the lighting should be switched on without the use of a 230 Vw voltage supply:
➤ Connect the cable with the positive terminal and the negative terminal of the vehicle battery.
➤ Feed the 12 Vg cable through the opening into the vehicle interior.

Installing the roof air conditioner with Chillout ADB

NOTICE! Damage hazard

Observe the structural strength of the roof of the vehicle. The roof of the vehicle must be able to bear the weight of the roof air conditioner. The roof must not be indented or deformed by the weight of the unit, even over a longer period of time.

See fig.10

➤ Lift the roof air conditioner onto the roof of the vehicle.
➤ Position the roof air conditioner over the installation opening. Observe the direction of travel.
