Transport
Transport
F135 should be transported and stored vertically in a
dry place.
Assembly
■F135 is installed freestanding on brackets or a suit-
able flat surface. Noise from the circulation pump,
fan and compressor can be transferred to the brack-
ets or the surface that F135 is placed on. Use the
product's adjustable feet to obtain a horizontal and
stable set-up.
30 - 50 mm
30 - 50 mm
15 - 40 mm
■F135 must be positioned with the back towards a
wall. Install the brackets or position F135 against an
outside wall, ideally in a room where noise does not
matter, in order to eliminate noise problems. If this
is not possible, avoid placing it against a wall behind
a bedroom or other room where noise may be a
problem.
■Wherever the unit is located, walls to sound sensitive
rooms should be fitted with sound insulation.
■Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
Installation area
Leave a free space of 800 mm in front of the exhaust
air module. Approx. 50 mm free space is required on
each side, to remove the side panels. The panels do not
need to be removed during service, all service can be
carried out from the front. Leave space between the
exhaust air module and the wall behind (and any
routing of supply cables and pipes) to reduce the risk
of any vibration being propagated.

General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
F135 is only designed for upright installation. All con-
nections are equipped with smooth pipe for compres-
sion ring couplings.
Overflow water from the evaporator's
collecting trough is routed via the sup-
plied plastic hose to a drain. Shape the
hose into a water seal (see image).
The entire length of the overflow water
pipe must be inclined to prevent water
pockets and must also be frost-proof.
To make the installation economical, NIBE recommends
that all pipes between F135 and the water heater are
insulated. The insulation should be at least 12 mm thick.
NOTE
The pipe systems need to be flushed out be-
fore F135 is connected so that any debris can-
not damage component parts.

System diagram
F135 is an exhaust air module.
When the air passes through the evaporator, the refri-
gerant evaporates because of its low boiling point. In
this way the energy in the air is transferred to the refri-
gerant.
The refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is led to the condenser. Here the
refrigerant gives off its energy to the hot water,
whereupon the refrigerant changes state from gas to
liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.

NIBE™ F135Chapter 4 | Pipe and air connections12

Connecting to indoor module
and air-water heat pump
XL8 and XL9 are connected to the return line between
the indoor module and the air-water heat pump. The
particle filter must be installed before F135 to prevent
dirt being deposited in F135. Install the shut-off valves
outside F135 to facilitate any future servicing.
Installation alternative
F135 must be connected according to the instructions
in this manual.
More information about the options is available at
www.nibe.eu.
Installation must be carried out in accordance with
current standards and directives.
Exhaust air
Connecting the exhaust air
When an exhaust air heat pump is connected, the heat
that is in the building's ventilation air is used to heat
up the building at the same time that the house is
ventilated.
The hot air is transferred from the rooms to the heat
pump via the exhaust air module.
NOTE
An air filter (HQ12) (enclosed), minimum clas-
sification G2, is required on the exhaust air
duct of this connection. The filter must be
cleaned regularly.
Caution
Noise from the fan can be transferred via the
ventilation ducts.
13Chapter 4 | Pipe and air connectionsNIBE™ F135

Docking NIBE air-water heat pump
The demand on F135 is controlled by the indoor mod-
ule in the system. The pump and fan speed are also
controlled from the menu in the indoor module.
NIBE™ F135Chapter 4 | Pipe and air connections14

Docking NIBE F135, VVM, outdoor air, pool,
cooling
F135 connected in air/water system with 4-pipe cool-
ing. 4-pipe cooling must, in this instance, be connected
between the outdoor air heat pump and F135. When
there is also a pool, the F135 must be connected
between 4-pipe cooling and the pool. The demand on
F135 is controlled by the indoor module in the system.
The pump and fan speed are also controlled from the
menu in the indoor module.
POOL
15Chapter 4 | Pipe and air connectionsNIBE™ F135

General air connections
Air installation must be carried out in accordance with
applicable directives.
To prevent fan noise being transferred to the ventila-
tion devices, it may be a good idea to install a silencer
in the duct, alternatively mount the enclosed silencer
in F135.
Connections must be made via flexible hoses, which
must be installed so that they are easy to replace. Ducts
that may become cold must be insulated with diffusion-
proof material (PE30) along their entire lengths. Ensure
that the condensation insulation is sealed at any joints
and/or at lead-in nipples, silencers, roof cowls or similar.
Provision must be made for inspection and cleaning of
the duct. Make sure that there are no reductions in the
cross-sectional area in the form of kinks, tight bends
etc., since this will reduce the capacity. The air duct
system must be a minimum of air tightness class B.
If there is a high hot water demand and incoming air
to F135 contains a lot of particles, the heat pump
module must be equipped with an air filter (HQ12)
(enclosed).

Install the filter cartridge
The filter cartridge has two sizes of connector, 125 mm
or 160 mm.
1. Check the diameter of the air channel for inlet air.
2. When the air duct has a large diameter (Ø 160 mm)
the inner ring must be cut out of the upper section
of the filter cartridge.
3. Cut just inside the inner edge of the outer ring us-
ing a sharp knife. The plastic is prepared for easy
cutting.
4. Press the filter cartridge into place in the connec-
tion for incoming air (XL43).

(XL43).
Install the silencer
1. Remove the plugs from the silencer enclosed.
2. Install the silencer in the connector for outgoing
air (XL44).
NIBE™ F135Chapter 4 | Pipe and air connections16

Exhaust air duct /kitchen fan
Exhaust air duct (kitchen fan) must not be connected
to F135.
To prevent food vapour being transferred to F135 the
distance between the kitchen fan and the exhaust air
device must be considered. The distance should not be
less than 1.5 m, but this can vary between different
installations.
Always use a kitchen fan when cooking.
NOTE
A duct in a masonry chimney stack must not
be used for extract air.
Ventilation flow (exhaust air)
Connect F135 so that all exhaust air except exhaust air
duct air (kitchen fan) passes the heat exchanger (EP1)
in the exhaust air module. Lowest ventilation flow must
comply with applicable standards. For optimum exhaust
air module performance the ventilation flow should
not be less than 25 l/s (90 m³/h). On occasions when
the exhaust air temperatures are lower than 20 °C (for
example on start-up and when there is no one at home)
the minimum value is 31 l/s (110 m³/h).
Ensure that the ventilation openings are not blocked.
If the exhaust air module is connected to the indoor
module, set the ventilation capacity in the menu system
(menu 5.1.5). Otherwise the ventilation capacity is set
via potentiometer (AA5-SF3).
Adjusting ventilation (exhaust
air)
To obtain the necessary air exchange in every room of
the house, the exhaust air devices must be correctly
positioned and adjusted and the fan in the exhaust air
module adjusted.
Immediately after installation adjust the ventilation so
that it is set according to the projected value of the
house.
A defective ventilation installation may lead to reduced
installation efficiency and thus poorer operating eco-
nomy, and may result in moisture damage to the house.
