This section describes the components in HCV500.
Please see the illustration on page 6 for references.
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 40°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 acces-
sory. 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 ex-
changer, where it releases its heat into the fresh outdoor air.
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 6 in
this service manual.
