Ventilation unit with heat recuperation ® DUOVENT COMPACT RV CAUTION! For units with a direct evaporator (marked DX and DXr in the unit code), the design air flow through the unit must be observed when operating the direct evaporator/condenser. It is acceptable to reduce the flow in cooling and heating mode by a maximum of 20 % of the design air flow.
Ventilation unit with heat recuperation ® DUOVENT COMPACT RV 5. INSTALLATION The unit can only be installed by a professional installation company authorized in accordance with the Trade Licensing Act. 5.1 PLACE OF INSTALLATION The unit can only be installed in accordance with the "Environmental Protocol", in which the characteristics of all devices that can be placed in this space are clearly defined, and it is not possible to place devices that would affect these conditions in any way.
Ventilation unit with heat recuperation ® DUOVENT COMPACT RV 5.1.2 HOW TO STORE THE UNIT AT THE DESTINATION The unit is designed for floor mounting in a vertical position. The unit must be placed on a solid base with a maximum limit deviation of 3 mm per 2 m of length.

Ventilation unit with heat recuperation ® DUOVENT COMPACT RV If the electric heater emergency thermostat of the unit trips again, it is necessary to immediately look for the cause of the fault. Repeated manual reset of the heater overheating error by a button on the heater is inadmissible and is not a solution to the fault. The reason for this type of failure may be insufficient air flow through the electric heater of the unit, which will cause the heating rods to overheat and the intervention of the emergency thermostat.
