7.1 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 wile installing the air con- ditioning roof unit:

• 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 and fig. 2, page 3 to check the dimensions of the installed unit. The dotted line indicates the middle of the sunroof open- ing.

• 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 parking cooler when the vehicle is in motion. The manufacturer of the air conditioning roof unit assumes no liability whatsoever.

• The roof inclination of the mounting surface may not exceed 20° in the direction of travel.

• 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).

• You can connect the unit to the battery via the lorry's terminal block or directly. The terminal block is to be preferred for the connection. On some vehicles, larger consumers connected to the terminal block are switched off after a short while if the power requirement is too high. Ask your vehicle manufacturer for the specifications of the terminal block. 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.

• 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. WARNING! Make sure that all electrical components are electrically discharged before carrying out work on them! RT780-Iveco--I-16s.book Seite 13 Donnerstag, 6. Juli 2017 3:16 15EN Installation CoolAir RT780

• When installing the system and making the electrical connections, observe the guidelines from the body manufacturer.

• Pay attention to the connection plan for the device:

Before installing the air conditioning roof unit, all connections to 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 mal- functions and the safety of the air conditioning roof unit, in particular to injuries and damage to property. NOTE After installing the unit, the specified parameters of the unit software must be checked (chapter “Configuration of unit software” on page 18). RT780-Iveco--I-16s.book Seite 14 Donnerstag, 6. Juli 2017 3:16 1515

7.2 Removing the sunroof

➤ Remove all screws and fixtures of the existing sunroof. ➤ Take out the sunroof. ➤ Remove the sealant around the opening, so that the surface is clean and free of grease.

7.3 Preparing unit fastening (Iveco Stralis AS³ only)

➤ Enlarge the 12 existing ∅ 6.5 mm holes for fastening the sunroof to a diameter of 8.5 mm.

7.4 Preparing the unit

➤ Place the air conditioning roof unit on a work surface with the housing facing down.

➤ Screw in the 12 self-threading M8 thread inserts in the blind holes marked with “1” and “4” (fig. 3, page 4). Use the supplied 1/4" bit for this. NOTE Dispose of all waste material, glue, silicone and seals separately. Observe the local disposal guidelines. NOTICE! During preparatory work on the surfaces, secure the unit from falling down. Make sure that the work surface is clean and level to ensure that the unit is not damaged. NOTICE! Screw in the thread insert vertically. Do not exceed the screw torque of 10 Nm.

7.5 Attaching the seal for the cab roof

7.6 Installing the unit in the sunroof

➤ Set the unit down centrally aligned and in the direction of travel (fig. 1, page 3) on the sunroof opening.

➤ Tighten the screws with a torque of 8 Nm. NOTICE! Ensure that the adhesive surface for the seal between the unit and the cab roof is clean (free of dust, oil, etc.). NOTE Make sure the air conditioning roof unit is centred perfectly. The seal must be applied continuously around the air conditioning roof unit after being placed on the roof of the vehicle. This is the only way to ensure a tight seal. 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. RT780-Iveco--I-16s.book Seite 16 Donnerstag, 6. Juli 2017 3:16 1517

7.7 Installing the electrical supply lines

lveco Stralis AS/AT: You can connect the unit to the battery via the lorry's terminal block or directly. The terminal block is to be preferred for the connec- tion. Ask your vehicle manufacturer for the specifications of the terminal block. lveco Stralis AS³: You can connect the unit to the battery via the lorry's terminal block or directly. Here, the connection directly to the battery should be pre- ferred, as the consumer which is connected to the terminal block switches off after approx. 10 min if there is a high power requirement. ➤ Lay the supply line and connect it to the vehicle (red line to plus, black line to minus). ➤ Plug in the supply line plug into the socket of the air conditioning roof unit supply line. ➤ To relieve strain on the supply line, secure it with a cable tie, e.g. to the cab roof. WARNING!

• The electrical power supply may only be performed by qualified personnel with specialist knowledge.

• Make sure there is no voltage present on electrically operated components before carrying out work on them! NOTICE!

• Fit a fuse of 25 amps 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 23). NOTE The unit is equipped as standard with:

If longer cable lengths are required, then the cable cross-section must be increased by an authorised specialist workshop: In this case cut off the cable as closely as possible to the unit (max. 0.5 m) and then establish a suitable connection with a larger cable cross-section. The manufacturer recommends:

• Iveco Stralis AS/AT: when the cable is extended by 4 m to 6 m in length, use a cross-section of at least 8 mm

• Iveco Stralis AS/AT: when the cable is extended by 9 m to 11 m in length, use a cross-section of at least 10 mm

7.8 Fastening the cover frame

➤ Fasten the cover frame (fig. 5 5, page 5) the same way as for the original frame for the sliding roof. 8 Configuration of unit software Before you first start up the unit, the controls can be adapted to suit the installation conditions. This must be done by the person installing the unit. In configuration mode, the following unit software parameters must be set at the control panel (fig. 7, page 6).
