1 General Informations
1.1. Scope of the Manual
This manual is an integral part of the air conditioner. It provides information for correct and efficient use. The manual is divided into parts for users and qualified technicians for installation. Special attention is drawn to text using the following symbols: ! This operation may result in dangers, ↑ Useful advice, ? Environment safety related information.
1.2. Manufacturer and Air Conditioner Data Plate
The data plate typically includes Manufacturer information, Conformity marking, Model/Serial number, Year of manufacture, and Technical data.
1.3. Description of the Air Conditioner
This air conditioner is designed for installation in vehicles like camping-cars, caravans, and motorhomes to improve temperature conditions. It supplies fresh, dehumidified air in summer and warm air in winter, but does not replace the vehicle's primary heating system. The user sets the temperature.
The system includes a compressor (a), condenser (b), evaporator (d), and refrigerant gas. The fan (c) circulates air. For cooling, air passes through the cooled evaporator, becoming cool and dehumidified. For heating, air is forced through an electrical heating resistance (e). Air is drawn in from outside and recirculated air is also used. Condensate drains from the unit.
1.4. How to Use the Air Conditioner
To enhance performance:
- Improve vehicle thermal insulation by closing openings and using reflecting curtains on glass surfaces.
- Avoid unnecessary opening of doors and windows.
- Select the most suitable temperature and speed.
- Direct air flaps appropriately.
Precautions to prevent issues and minimize risks:
- Do not obstruct air inlets/outlets with cloths or objects.
- Do not insert hands or objects into openings.
- Do not spray the unit with water.
- Keep flammable substances away from the air conditioner.
Adjusting the Air Direction: Use the air diffusing flaps to direct airflow. Rotate the center knob counter-clockwise to select the desired position, then clockwise to lock it.
Diagram shows hands adjusting air diffusing flaps on the unit, with arrows indicating different airflow directions.

B2200 Remote Control
The remote control allows operation of the air conditioner. Key buttons include:
- ON/OFF: Starts or stops the air conditioner. When off, only the clock is visible, and ROOM/LIGHT buttons may function.
- F°/C°: Selects temperature units (Fahrenheit or Celsius).
- LIGHT: Activates the air diffuser light (if equipped). Works even when the remote is off.
- ROOM: Displays the room temperature instead of the set point. Pressing again reverts to the set point display. Works when the remote is off.
- CLOCK: Used to set the time. Press and hold for over 2 seconds to enter time setting mode, using UP/DOWN buttons, then press SET to confirm. Settings are confirmed after 15 seconds.
- SET: Confirms time settings or resends the current operating setting.
- TIMER: Sets automatic startup and/or shutdown times.
- SLEEP: Activates SLEEP mode, automatically adjusting the set point for comfort during sleep (lowers by 1° after one hour, 2° after two hours).
- I FEEL: Adjusts operating temperature based on detected remote control temperature. Ensure the remote is not in extreme temperature conditions.
- RESET: Resets all configuration parameters to default.

2 Installation Instructions
The air conditioner must be installed by skilled technicians. Ensure working conditions are safe for all involved.
2.1. Packaging, Unpacking, and Handling
Follow instructions printed on the packaging. Remove the air conditioner carefully, ensuring it is not damaged. Never use the rear air openings to lift the unit from its packaging. Move the unit to the installation site under safe conditions.
Diagrams show: 1. Following instructions on the box. 2. Removing the unit from packaging, highlighting not to use rear openings for lifting. 3. Unit on a stand. 4. Moving the unit to the installation site.
2.2. Preparing the Roof Opening
The roof requires an opening of suitable size. An existing air inlet can be used, or a new one can be made. The unit should be installed in the center of the vehicle's width and length. Ensure the opening does not interfere with existing vehicle furnishings (lamps, wardrobes, doors, curtains, etc.) for easy mounting and proper airflow. Contact the vehicle manufacturer to confirm roof structure can support the unit's load and stresses. Some manufacturers may pre-prepare areas for installation. The air conditioner should be installed on a level plane, with a maximum allowed inclination of 10°.
Diagrams show: 1. A roof opening with dimensions (400x400mm). 2. A vehicle outline indicating central placement. 3. Cross-section views of the unit on the roof, showing seals and mounting.
Electrical Hazard Warning: Turn off all power sources before proceeding.
Using an Existing Opening: 1. Remove the skylight cover. 2. Clean the opening by removing adhesive residues. 3. Fill any screw holes or deformations with filler or silicone.
Diagrams show: 1. Removing a skylight cover. 2. Cleaning the opening edges. 3. Filling holes.
New Installation Opening: 1. Use the provided cardboard template to mark the opening position and dimensions. 2. Drill the four corners. 3. Cut by joining the drilled holes. 4. If necessary, install a reinforcing wooden frame.
Diagrams show: 1. Using a template to mark an opening. 2. Drilling corners. 3. Cutting the opening. 4. A finished opening with dimensions and a hole for supply cables.
2.3. Mounting the Air Conditioner
- Set the air conditioner onto the roof opening. Lift, do not slide. Ensure conical pins under the base enter the roof openings.
- Fix the air diffuser brackets to the base using the 4 provided screws.
- Tighten screws to the recommended torque setting (2.5 Nm / 0.25 kgm). Do not overtighten.
- Mount the air diffuser linking gaskets. Refer to the table on page 21 for correct thickness based on roof thickness.
- Perform the electrical connection as described in paragraph 2.4.
- Fix the cooling unit to the brackets using the 4 provided screws.
- Mount the filters in the specified order.
- Mount the filter covers.
Diagrams illustrate each step: placing the unit, attaching brackets, tightening screws, fitting gaskets, connecting wires, securing the cooling unit, and installing filters/covers.

| Thickness of the Roof | Thickness of the Gasket |
|---|---|
| from 30 to 35 mm | 10 mm |
| from 35 to 40 mm | 15 mm |
| from 40 to 45 mm | 20 mm |

| from 75 to 80 mm | 55 mm |
| from 75 to 80 mm | 60 mm |
2.4. Electric Connection
Follow national and local regulations for electrical connections. Arrange a specific electric system based on cable length and cross-section requirements (e.g., < 7.5m requires 1.5 mm², > 7.5m requires 2.5 mm²).
The unit connects via a 12-pole connector from the air conditioner base to a 12-pole connector on the electronic device inside the air diffuser. Connections include Red wire, Black wire (for 12V DC battery), and Cyan wire, Brown wire, Green-Yellow wire (for 230V 50Hz).
Connect the electric system to a circuit supplying the required power and fitted with a good ground system. This involves connecting to the supply mains, fuse box, change-over switch (mains/generator), electric power generator, and a thermomagnetic cutout (RCCB).
Diagrams show: 1. Cable length vs. cross-section. 2. Wiring connections for 12V DC and 230V AC, detailing wire colors and connector types. 3. A schematic of the electrical system connection to the vehicle's power sources.
