NOTICE!
The air conditioning roof unit may only be installed by qualified personnel from a specialist company. The following information is intended for technicians who are familiar with the guidelines and safety precautions to be applied.
6.1 Notes on installation
These installation instructions must be read completely prior to the installation of the air conditioning roof unit.
The following tips and instructions must be observed while installing the air conditioning roof unit:

WARNING!
Ensure that all electrical components are electrically discharged before carrying out work on them.
- Always check whether any vehicle components could be damaged or their operation impaired by the unit before installing the air conditioning roof unit. You can use fig. 1, page 3 to check the dimensions of the installed unit.
● The supplied assembly parts must not be modified during installation. - The ventilation slots (grill) may not be covered (minimum distance from other attachment parts: 10 cm).
- For installation and repair work, adhere to the corresponding rules of technology.
- When installing the system and making the electrical connections, observe the guidelines from the body manufacturer.
- Use appropriate tools for each step of the installation.
- Prior to and during drilling, note the location of existing cable harnesses, cables and other components.

WARNING!
Before installing the air conditioning roof unit, the power supply at the battery of the vehicle must be disconnected. Non-observance of this regulation can result in danger of electrocution.

CAUTION!
Improper installation of the air conditioning roof unit can result in irreparable damage to the device and put the safety of the user at risk. The manufacturer will not be held liable for claims if the air conditioning roof unit is not installed according to this installation manual. That applies to malfunctions and the safety of the air conditioning roof unit, in particular to injuries and damage to property.
6.2 Steps for installation

NOTICE!
- 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.
- Check whether the roof of the vehicle is able to support the weight of a person before climbing onto it. Ask the vehicle manufacturer about the permitted roof loads.
- Before installing the air conditioning system on the roof, protect the upper part of the cabin with a cloth or a blanket to prevent any scratches or damages.
6.2.1 Checking installation conditions
Before installation, check (by consulting the manufacturer of the vehicle) whether the construction is designed for the static weight and the loads of the air conditioning roof unit when the vehicle is in motion. The manufacturer of the roof air conditioner assumes no liability whatsoever.
Cabins with a sunroof generally have a robust structure in order to bear the weight of the air conditioner.
Where this is not the case, and the structure is not rigid enough to bear the weight of the air conditioner (e.g. fibreglass roofs or for roofs with pre-existing cut-out sections), you must check whether the cabin roof needs to be strengthened.
▶ Check the minimum requirements for the installation of an air conditioning roof unit
- Vehicle voltage
– Power consumption - Generator power
– Size and load bearing capacity of the cabin
▶ Check the output voltage of the three phase generator (14 – 15 V).
▶ Check the efficient functioning of all electrically operated vehicle components.
▶ If deviations are identified, please inform workshop management or the vehicle owner.
6.2.2 Preparing the unit fastening
Place the unit on the roof and make sure that the roof area of the cabin is level (fig. 2, page 3).
▶ Check whether the cut-out sections for the air inlet and outlet and the installation of the cover can be completed inside the cabin.
▶ Remove the cover of the air conditioning roof unit.
▶ Mark the six fastening holes ∅ 10 mm (fig. 3 1, page 4).
▶ Mark the rectangular opening for the air inlet (fig. 3 2, page 4).
▶ Mark the rectangular opening for the air outlet (fig. 3 3, page 4).

NOTICE!
Check that under the roof plate there are no electric wires, lining or vehicle facilities near the holes.
▶ Perform the holes and the openings (fig. 4, page 4).
▶Protect the holes and the openings with antioxidant.
6.2.3 Attaching the seal

NOTICE!
Ensure that the adhesive surface for the seal between the unit and the cab roof is clean (free of dust, oil, etc.).
▶ Apply sealing or something similar to prevent any water from getting between the holes and the air vents (fig. 5, page 5).
6.2.4 Installing the unit on the cab
▶ Place the unit on the roof so that the holes match (fig. 6, page 5).
▶ Attach the unit with six M8 screws (fig. 6 1, page 5), with twelve washers (fig. 6 2, page 5) and six self-tapping M8 nuts (fig. 6 3, page 5).

NOTICE!
Do not exceed the specified torque under any circumstances. This is the only way to ensure that the thread inserts are not torn out.
▶Tighten the screws with a torque of 8 Nm.
▶ Fasten the condensate drain hose (fig. 7 1, page 6) to the system.
▶ Align the condensate drain hose by turning so that the condensation can drain.
6.2.5 Connecting electrically

WARNING!
- The electrical power supply may only be performed by qualified personnel with specialist knowledge.
- Ensure there is no voltage present on electrically operated components before carrying out work on them.

NOTICE!
● Fit a fuse of 60 A to the connection to the vehicle's power supply.
- The battery must be able to supply the required current and voltage (chapter "Technical data" on page 35).
Connecting inside the air conditioning roof unit (fig. 8, page 6)
▶Select the minimum gauge for the connection cables according to the following table:
| Cable length | Minimum gaugeFor 12 V systems | Minimum gaugeFor systems with24 V, 48 V, 80 V |
| 1 m 16 mm ^2 10 mm ^2 | ||
| 2 m 25 mm ^2 10 mm ^2 | ||
| 3 m 35 mm ^2 16 mm ^2 |
▶ Connect the positive power cable to the red cable of the block (1).
▶ Connect the negative cable to the black cable of the block (2).
Connecting outside the air conditioning roof unit (fig. 9, page 6)
▶Connect the two-pin Metri-Pack sealed 280 plug to:
– Position A (1): positive terminal (red), protected by a 20 A fuse
– Position B (2): negative terminal (black)
Connecting the control panel (fig. 10, page 7)
▶ Connect the 5-pin black plug to the ventilation switch (1).
▶ Connect the 3-pin black plug to the temperature switch (2).
▶ Connect the green wire to the On/Off switch (3).
▶ Connect the red-black wire to On/Off switch (3).
6.2.6 Attaching ventilation panel

NOTICE!
Check prior to installation that there are no electrical cables or hoses between roof and ventilation panel.
▶ Place the ventilation panel in the cabin under the roof (fig. 11, page 7).
Position the ventilation panel so that:
- the air inlet grill is under the air inlet opening (fig. 12 1, page 7) of the air conditioning roof unit
- the three air outlet nozzles are under the air outlet opening (fig. 12 2, page 7) of the air conditioning roof unit

NOTE
The length of the fastening bolts for the ventilation panel depends on the thickness of the lining of the roof interior.
Make sure, before screwing the ventilation plate in place, that the length of the bolts do not interfere with the air conditioning roof unit.
▶ Select fastening bolts (not included in scope of delivery) which are appropriate for the roof thickness and the strength of the bodywork.
▶ Attach the ventilation plate (fig. 12, page 7).
7 Operating

NOTE
The air conditioning roof unit runs in circulation mode. For this reason, the cabin door and other existing openings must be closed during operation.
Do not run the air conditioning roof unit if the vehicle must be used for work which needs the cabin door open.
The air conditioning roof unit can be set at the control panel (fig. 13, page 8):
