Installation location
• To install the device it is necessary to create openings in the floor. Ensure that the openings are accessible and
not covered by any parts of the vehicle.
• Before installing the underbench air conditioner, ensure that no vehicle parts can be damaged by the installa-
tion of the under-bench air conditioner (e. g., wirings, lamps, cabinets, doors).
• The inclination of the installation surface must not exceed 10 °.
• Install the under-bench air contitioner in a central location of the vehicle (e. g., in a compartment or similar
housing) to achieve optimal air conditioning of the vehicle.
• Choose a location that is easily accessible for maintenance, disassembly, and installation.
• The under-bench air conditioner must be installed on the floor.
• Before drilling holes place the mounting template in the selected compartment to check the available space
for the holes on the floor.
• Ensure that the under-bench air conditioner has a minimum distance of 30 mm from walls and furniture all
around to minimize the transmission of noise and vibrations during operation.
• Keep a distance of 20 cm between the front of the under-bench air conditioner and the walls of the compart-
ment to facilitate filter replacement.
• When installing the under-bench air conditioner in an external compartment (e. g., false floor), the air to be
treated must be drawn from the passenger compartment of the vehicle.
• Ensure that no outside air is drawn in. The intake of outside air can significantly reduce the efficiency of the un-
der-bench air conditioner.
