Subject to Technical Modifications of GV-HR110
Duct connection
All duct connections have yellow markings that
indicate which ventilation ducts are connected to the
different connections.
Incoming air connection:
The duct system from the aggregate to the residence.
Outgoing air connection:
The duct system from the residence to the aggregate.
Outside air connection:
The duct system from the outside air hood/outside air grid
or from the ground heat exchanger to the aggregate.
Exhaust air connection:
The duct systems from the aggregate to the exhaust
air hood/exhaust air grid outdoors.
Optimal operation of the GV-HR110 is achieved by
mounting a connector piece Ø160 mm in each of the
four outlets as the first stepp of the duct system. The
connectors are tightened with the supplied collar bands.
Condensation drain
The aggregate produces up to 6 litres condensation
per day. It is therefore important that the condensation
drain is set up correctly and that the aggregate declines
toward the condensation drain side.
The waterseal must be airtight e.g. by bending a 15 mm
copper pipe as a waterseal (see the drawing on the left).
A reinforced water hose is attached between the drain
connection and the waterseal using a hose clip on both
connections.
A necessary decline of 1 % is installed from the waterseal
to the inside drain. If the aggregate is mounted in a
cold air room then the condensation drain pipe must be
insulated so that the condensation inside the pipe does
not freeze. We also recommend that the waterseal is
mounted in an underlying warm room to guarantee that
the water in the waterseal does not freeze.
If protection of the condensation drain pipe against frost
cannot be guaranteed when installing then a thermostat-
controlled heating strip must be assembled around the
condensation drain pipe. When hanging on wood walls
we recommend using a vibration-dampener to avoid
transferring vibrations.
No water in the waterseal = water damages
During operation there is negative pressure in the
aggregate, which makes it necessary to guarantee
a height difference of at least 50 mm down to the
water in the waterseal.
