1.1. Scope of the manual
This manual provides information for the user and for installation personnel.
1.2. Manufacturer and machine identification
Refer to the machine dataplate for manufacturer and technical specifications.
1.3. Machine description
This machine is designed and built to be installed on vehicles (motor homes, caravans, special vehicles, etc.) to improve the internal temperature. It supplies cool and dehumidified air in hot weather, and hot air in cold weather, without replacing the vehicle's original heating system. The air temperature is adjustable.
Cool air - Description of operation
The system comprises a compressor, condenser, evaporator, a 4-way valve, and pressurized refrigerant. The refrigerant, by changing physical state from liquid to gas, heats or cools the components through which it passes. The evaporator, cooled by the internal air blown by the fan blower, cools and dehumidifies the air. This action, over time, reduces the temperature inside the vehicle.
Hot air - Description of operation
The refrigerating cycle is reversed by the 4-way valve. The internal coil changes from evaporator to condenser, heating the air passing through it. A heating element increases the efficiency of the heat pump at low temperatures.
1.4. User tips
- Improve vehicle heat insulation by eliminating openings and covering glass surfaces with reflecting curtains.
- Avoid frequently opening doors and windows.
- Select the appropriate temperature and fan speed. Direct air vents suitably.
- Precautions for safe operation:
- Do not obstruct the ventilation air inlet and outlet.
- Do not put hands or other items into the openings.
- Do not spray water inside the machine.
- Keep flammable substances away from the machine.
- Clean the air filter periodically.

Active Carbon filter (2) (optional): It is recommended to change the active carbon filters every year.
Information on installation
Installation can be performed by persons with specific technical knowledge. Installers must have adequate working conditions to ensure their own safety and that of others.
2.1. Packing, unpacking and handling
- Observe the instructions given on the packing.
- Lift the machine, checking it is sound. Lift using the handles or belts on the base.
- Transfer the machine to the place of installation in conditions of safety.
2.2. Choice of the place of installation
Install the machine as near the middle as possible in a housing or similar device for uniform climate control. Position for easy servicing and disassembly. Place the assembly template and check space for floor openings. Maintain a minimum clearance of 30 mm from walls and fittings to minimize noise and vibration. Install on the floor. Keep a distance of 200 mm from the front of the machine to walls for easier filter replacement. If fitting in external compartments, draw air from the passenger compartment; drawing in outside air can reduce system power.
2.3. Preparing the opening and fixing
Create openings in the floor, ensuring they are accessible and not covered by chassis parts. Protect from wheel splashes if necessary. Leave at least 30 mm gap between the machine and adjacent walls. Secure the machine to the floor using the provided kit. Install preferably level, with a maximum angle of 10° to prevent condensation leakage. Before making holes, check for hidden cables, pipes, or chassis parts. Seal machined surfaces with water-repellent products.
2.3.1. Fixing systems
The manual details three fixing modes using screws, brackets, and belts. Diagrams illustrate the parts supplied and how to assemble them for each mode.
2.4. Fitting the infrared wall pad
A pocket for the wall pad, remote control, and extension cable is located on top of the machine. To fix the wall pad, make a 20mm diameter hole in the wall for the cable. Use two wooden screws to fix the support to the wall, connect the extension cable to the wall pad, and place the wall pad into its support.
2.5. Compartment opening and electrical hook-up
Make a hole in the compartment for internal air recirculation, ensuring at least 300cm² of air passage. Close with a grille (not supplied). Install provided condensation drain pipes. Connect the receiver extension to the machine. Power up by inserting the Schuko plug into a 220V 60Hz socket outlet. Before switching on, verify that the campsite column and extension can withstand the machine's power input.
2.6. Air ducting
Use trade parts for air ducting. Recommended: cardboard pipe with aluminum core and PVC covering, 60mm inside diameter, 65mm outside diameter. Join pipes by pressing them into the tapered hole on the air outlet. Pipes can connect to the coil side outlet or, by removing the guard and closing front holes, to the side outlet.
For best efficiency:
- Lay air pipes as short and straight as possible.
- Do not use pipes longer than 5m.
- Do not place pipes near heat sources.
Recirculation air is drawn through a grille or openings with at least 300cm² total cross-section, located near the machine. Ensure air flow is not obstructed. Create an air duct if necessary. Recirculation air must be taken from the passenger compartment; drawing outside air reduces efficiency.
