If the unit is not to be installed immediately, it should be stored in a clean, dry area. If stored exter-
nally, it should be adequately protected from the weather.
2. BRIEF DESCRIPTION OF THE UNIT
• Casings of air handling units are made of galvanized steel sheets, which are powder painted. Mineral
wool is used for thermal insulation and sound attenuation. Unit cover panels are 45 mm thick.
• The air handling units are intended for ventilation of medium-sized spaces (eg. single family houses,
offices, etc.), having operating ambient temperature and relative humidity. As standard, the unit is
designed for indoor placement. The operating temperature range for the unit is -30 °C ... 40 °C, out-
door air temperature. Heat pump operation limits are from -20 °C to +40 °C. For reliable air handling
unit operation is recommended to use air handling unit in the room with temperature between
18-28 ˚C.
• The air handling unit is not to be used to transport solid particles, even not in areas where there is a
risk of explosive gases.
• RHP units is equipped with a rotary heat exchanger, air filters, an electric or water heater, fans and
automation control system, to ensure safe and efficient operation of the unit.
• Before you open the door, the unit must be switched off and the fans must have been given time to
stop (up to 3 minutes).
• The unit contains heating elements that must not be touched when they are hot.
• We recommend to leave air handling unit in working mode (minimum 20 percent of power) during
the first operation year. Due to moisture in building constructions, condensation may occur inside
and outside the air handling unit. Continuous operation of the equipment will significantly reduce
the risk of condensation.
• To maintain a good indoor climate, comply with regulations and, to avoid condensation damage,
the unit must never be stopped apart from during service/maintenance or in connection with an
accident.
• If the unit is placed in spaces with high humidity, condensation might occur on the surface of the
unit when outdoor temperatures are very low.
• Under conditions, when the outdoor air temperature is low and humidity is high, risk of heat ex-
changer frosting may appear. For this reason anti-frost protection function is foreseen in the
controller of the Komfovent air handling units. Depending on the type of the recovery, different
methods of anti-frost protection are available: cold air by-passing, or / and supply air fan speed
reducing. For extremely low outdoor air temperature the duct mounted preheater is recommended.
The lowest risk and the highest resistance to cold outside air is a competitive feature of the rotary
heat exchanger, as it is not freezing even at the temperatures of -30 °C if the humidity level of the
air is appropriate.
• If one or both air flow(s) are lower than meaning in table 1, heat pump will be switch off and informa-
tion icon will be displayed on control panel.
• When device controlling mode is set by supply air temperature, at that moment when supply air
temperature is same as setpoint or exceed it, heat pump may be turned off (heat pump kept turned
off for minimum 6 minutes). Maximum stopping number is five times per hour. Therefore it is recom-
mended, set the device controlling mode under the indoor temperature (duct or room) for stable
operation of the device.
• In heating mode supply air temperature can range due to frozen evaporator. Therefore, this unit is
not recommended for use as a basic unit for heating. Unit has integrated supply air second electric
heater.
• When heating mode is changed to cooling mode (or contrary) heat pump is turned off. After stop-
ping heat pump cooling/heating function will start after 6 min.
