Notes on installation
The following tips and guidance should be followed when installing the parking cooler:

WARNING! Electrical shock
Before carrying out any work on electrically operated components, make sure that they are disconnected from the power supply.
Before installing the parking cooler, disconnect all connections to the vehicle battery.

• Before installing the parking cooler, check whether any vehicle components could be damaged or have their function impaired as a result of the installation. Check the dimensions of the system to be installed (fig.2). The dotted line indicates the middle of the roof hatch opening.
• The top cowl of the parking cooler can be painted (fig.3). The manufacturer recommends that the painting is done by a specialist paint shop.
• Before installation, check with the vehicle manufacturer whether the vehicle body is designed for the static weight of the parking cooler and the dynamic loads created by it when the vehicle is in motion. The manufacturer of the parking cooler accepts no liability whatsoever in that regard.
• If a roof cutout is required (e.g. if there is no existing roof hatch opening or the roof hatch opening is not suitable and cannot be used), it is mandatory to check with the manufacturer of your vehicle whether this is permissible and what must be observed to ensure that the vehicle’s registration does not expire.
• The downward slope of the roof in forward direction in the area where the unit is installed must not be more than:
  • RTX1000: 8°
  • RTX2000: 20°
• The assembly parts supplied must not be modified during installation.
• The ventilation openings must not be covered over (minimum distance from other external attachments: 100 mm).
• Follow the vehicle manufacturer’s guidelines when installing the system and establishing the electrical connections.

NOTE
After installation of the system, the pre-set parameters on the system software must be checked (chapter “Configuring the system software” on page 13).

Creating the opening (if necessary)

NOTE
To simplify the task of creating the opening, there is a template integrated in the packaging of the installation kit.

• Create an opening measuring 500 mm x 400 mm with rounded corners with a radius of R25 (fig.6 and fig.7, arrow = forward direction).

NOTE
Dispose of all waste materials separately. When doing so, follow the waste disposal requirements applicable in your local area.

Preparing the unit

NOTICE! Damage hazard
When preparing the unit on the work surface, make sure it is secured against falling off.
Make sure that the work surface is clean and level to ensure that the unit is not damaged.

Proceed as follows (fig.8):

• Place the parking cooler on a work surface with the casing facing down.
• Screw the 4 self-tapping M6 threaded plugs into the blind holes marked “7”. Use a 5 mm hexagon bit to do so.
• Screw the 4 self-tapping M8 threaded plugs into the blind holes marked “6”. To do so, use the 1/4″ bit supplied.

Attaching the seal for the cab roof

NOTICE! Damage hazard
Ensure that the surface where the seal between the unit and the cab roof is to be glued is clean (free of dust, oil, etc.).

• Glue the sealing strip to the cab roof (fig.9A). Follow the contour of the roof hatch opening. The join between the ends of the seal should be at the back.
• Apply a flexible, non-hardening butyl sealant (e.g. SikaLastomer-710) to the join between the ends of the sealing strip and to the top edge of the sealing strip (fig.9B).

Fitting the unit in the roof hatch

CAUTION! Risk of injury
Only install the unit in support of e. g. second person, crane, working platform. The work safety must be guaranteed at all times.

• Place the parking cooler as shown and facing forwards in the roof hatch opening (fig.0).

NOTE
Once the unit is in position on the vehicle roof, the seal should make contact all the way round. Only then can a reliable seal be achieved.

• Position the fixing brackets underneath the cab roof (fig.a). When doing so, slide the fixing brackets between the cab roof (chassis) and the roof lining (if existing).

NOTICE! Damage hazard
Do not exceed the specified tightening torque under any circumstances. That is the only way to ensure that the threaded plugs are not pulled out.

• Fix the parking cooler in place as illustrated (fig.a).
• Establish the required length of the M8 hexagon-head screws as follows: Screw length = Distance between bottom edge of fixing bracket and bottom edge of unit plus 5 – 9 mm.
  If necessary, shorten the hex-head screws to the size determined.

Routing the electrical power supply leads

DANGER! Explosion hazard
For EX/III and FL vehicles (according to ADR guideline), a battery master switch must be installed.

WARNING! Risk of injury

• The electrical connections may only be made by competent technical staff with the appropriate specialist knowledge.
• Before carrying out any work on electrically operated components, make sure that they are disconnected from the power supply.

NOTICE! Damage hazard

• The connection to the vehicle’s electrical system should be protected by a 40 A(RTX 24 V)/80 A (RTX 12 V) fuse for the power supply and a 2 A fuse for the voltage monitor.
• The battery must be capable of supplying the required current and voltage (chapter “Technical data” on page 16).
• Route the power supply lead stressless and secure it with cable binders in appropriate intervals.

Route the power supply lead as illustrated (fig.b):

• The connector must be fixed to the support bracket (fig.b3.).
• Run the wiring loom to the main power distribution box along a route where it is protected.
• Connect the negative lead (black) for the power supply.
• Connect the negative lead (black) for the voltage monitor.
• Connect the positive lead (red) for the power supply via a fuse:
  • RTX 24 V: 40 A
  • RTX 12 V: 80 A
• Connect the positive lead (red) for the voltage monitor via a 2 A fuse.
• Connect the wiring loom to the unit and fix with a cable tie in a suitable position (fig.b2.).

Fixing the cover frame

NOTICE! Damage hazard
Tighten the screws carefully in order not to damage the cover frame

• Fix the cover frame in place as illustrated (fig.c).

The distance “x” has to be measured again. This measure is needed to determine the spacer and screw length for the fastening of the cover frame.

Example:

• Screw length = x + (23 to 27) mm:
  In case “x“ is 51 mm, the suitable screw length is 75 mm

• Spacer length = x + 9 mm:
  In case “x” is 51 mm, the suitable spacer length is 60 mm
