Nibe F110 - Installation Alternative

Installation alternative
F110 must be connected according to the instructions in
this manual.
EXHAUST AIR
Connecting the exhaust air
With an exhaust air connection the heat in the building's
ventilation air is used to heat the hot water while the house
is ventilated.
The hot air is transferred from the rooms to the heat pump
via the house ventilation system.
NOTE
Install the enclosed air filter (HQ12) on the exhaust
air duct. The filter must be cleaned regularly.
Caution
Noise from the fan can be transferred via the
ventilation ducts.
OUTDOOR AIR
Connecting the outdoor air
With outdoor air connection the heat in the outdoor air is
used to heat up the hot water.
• The pressure drop in the system must not exceed 60 Pa.
Factors affecting the pressure drop include the dimen-
sions of the air ducts, the number of bends and the length
of the ducts. Example: In a system with 160 mm air ducts
and 7 bends, the ducts may be a maximum of 8 m in
length.
• Attempt to find a location for F110 on the side of the house
that faces the least sound sensitive neighbouring area.
Caution
Noise from the fan can be transferred via the air
ducts.
