This section describes the individual components of the HCV 400, which are part of standard
delivery .
The external parts of the cabinet are manufactured from powder coated, AZ-coated steel
plating . The internal parts of the cabinet are manufactured from expanded polystyrene (EPS) .
Accessories are installed after removing the steel front and EPS doors . The cabinet is sound
and heat insulated with fire retardant polystyrene foam . The unit is designed for installation in
ambient temperatures from 12° to 50°C .
The unit is equipped with a class G4 cassette filter as standard . These filters protect the heat
exchanger and improve the indoor climate by filtering the air of dust and other particles . An
F7 filter (pollen filter) can be purchased as an accessory . The F7 filter is always placed on the
supply side - shown on the top of the unit .
The reverse flow heat exchanger absorbs the heat energy from the evacuated air and moves
it to the fresh air, thereby saving on energy needed for heating .
The supply fan adds fresh air from outside through the heat exchanger to the ventilated
indoor rooms .
The extractor fan sucks out stale and moist air from the home through the heat exchanger,
where it releases its heat into the fresh outdoor air .
The motorized bypass damper overrides the heat exchanger functionality . This is used in
warm summer conditions, where colder outside air can be used for reducing inside tempera-
ture, when inside temperature exceeds an upper temperature limit .
The unit is equipped with two drain valves . One of these must be connected to a drain hose
to direct the condensate to a drain .
Correct connection to the drain valves is shown at the top of the unit and on page 20 in
this service manual .
The humidity sensor will continuously monitor the quality of the extract air, and adjust the air
flow level accordingly . This operation is named demand mode . If a HRC remote control is con-
nected, the level will be shown in the display using 3 level icon .
Using demand mode will result in the correct level of ventilation with lowest possible electri-
cal power consumption .
