DESIGNATION KEY

TECHNICAL DATA

The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing. In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above the dew point temperature of the transported air. The unit should be operated continuously, and in cases where ventilation is not necessary, reduce the air flow of the fans to a minimum (20%). This will ensure a favorable indoor climate and reduce the amount of condensation inside the unit, which can damage electronic components. Never use the unit for dehumidification, for example, of new buildings. The unit is rated as a Class I electrical appliance.

Hazardous parts access and water ingress protection rating:

• IP22 for the unit connected to the air ducts
• IP44 for the unit motors
• The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

DESIGN AND OPERATING PRINCIPLE

The unit has the following operating principle: stale extract air from the room flows to the unit, where it is filtered. Then the air is moved through the rotary heat exchanger and is exhausted outside with the exhaust fan. Clean air from outside is moved to the supply filter. Then filtered air flows through the rotary heat exchanger and is moved to the room with the supply fan. Heat exchange between extract air and intake air takes place in the rotary heat exchanger. Heat recovery minimizes heat losses and space heating expenses in cold seasons and cooling expanses in warm seasons. The KOMFORT Roto EC S6EK 200 unit is equipped with an electric heater for preheating the supply air. The unit is equipped with an additional extract spigot for connecting a kitchen hood. The air handling unit is equipped with quick- detachable service panels for scheduled repair and maintenance operations .
