Condensation Water Drain - Nibe GV-HR 130 Series Installer Manual

Condensation water
drain
GV-HR 130 can produce several litres of condensation
water per day. It is therefore important for the condens-
ation outlet to be correctly executed and for the ventila-
tion heat exchanger to be installed horizontally.
Check that the water seal is airtight and firmly in posi-
tion. The connection must be made so that the user can
check and top up the water seal, without opening GV-
HR 130.
Installation from the water seal through to the drain
must be carried out with an essential fall of 1 %. If the
ventilation heat exchanger is installed in a cold area, the
condensation water drain pipe must be insulated so that
the condensation water in the pipe does not freeze. It
is also recommended that the water seal is mounted in
a heated area to guarantee that the water in the water
seal does not freeze.
If it cannot be guaranteed that insulation will protect the
condensation water drain pipe against frost, a thermostat
controlled heating cable must be installed around the
condensation water drain pipe.
NOTE
During operation, negative pressure arises in
the ventilation heat exchanger, which means
that a water column of at least 100 mm must
be guaranteed in the water seal.
