•S135 is installed freestanding on brackets or a suitable
flat surface indoors. Noise from the circulation pump,
fan and compressor can be transferred to the bracket
or the surface on which S135 is placed. Use the
product’s adjustable feet to obtain a horizontal and
stable set-up.
30 - 50 mm
30 - 50 mm
15 - 40 mm
20-55 mm
•S135 must be positioned with the back towards a wall.
Install the brackets or position S135 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 bed-
room 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 product.
Leave free space between S135 and wall/other ma-
chinery/fittings/cables/pipes etc. It is recommended that
a space of at least 10 mm is left to reduce the risk of
noise and of any vibrations being propagated.
* Depending on whether the panels can be removed or
not.
NOTE
Ensure that there is sufficient space (300 mm)
above S135 for installing ventilation hoses.

General pipe
connections
Pipe installation must be carried out in accordance with
current norms and directives.
S135 is only designed for upright installation. All connec-
tions are equipped with smooth pipe for compression
ring couplings.
A safety valve must be installed in the system where
S135 is present.
Overflow water from the evaporator's collect-
ing trough is routed via the supplied 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 energy efficient, NIBE recom-
mends that all pipes between S135 and the indoor
module are insulated. The insulation should be at least
12 mm thick.
NOTE
The pipe systems need to be flushed out be-
fore S135 is connected so that any debris
cannot damage component parts.

SYSTEM DIAGRAM
S135 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.

Installation exhaust air
S135 must be connected according to the instructions
in this manual.
Installation must be carried out in accordance with cur-
rent standards and directives.
EXHAUST AIR
Connecting the exhaust air
The heat pump uses the heat that is in the building's
ventilation air to heat the building and the hot water 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 classi-
fication G2, is required on the exhaust air duct
for this connection. The filter must be cleaned
regularly.
Caution
Noise from the fan can be transferred via the
ventilation ducts.

DOCKING NIBE AIR/WATER HEAT PUMP
The demand on S135 is controlled by the indoor module
in the system. The pump and fan speed are also con-
trolled from the menu in the indoor module.

HEAT PUMP, POOL, COOLING
S135 connected in air/water system with 4-pipe cooling.
In these cases, 4-pipe cooling must be connected
between the air/water heat pump and S135. Where
there is also a pool, S135 must be connected between
4-pipe cooling and pool. S135 can produce hot water at
the same time as the air/water heat pump is producing
cooling. A shut-off valve (QN44) is required for this. The
demand on S135 is controlled by the indoor module in
the system. The pump and fan speed are also controlled
from the menu in the indoor module.

General ventilation
connections
• Ventilation installation must be carried out in accord-
ance with current norms and directives.
• Connections must be made via flexible hoses, which
should be installed so that they are easy to replace.
• Provision must be made for inspection and cleaning
of the duct.
• Make sure that there are no reductions of cross-sec-
tional area in the form of creases, tight bends, etc.,
since this will reduce the ventilation capacity.
• The air duct system must be a minimum of air tight-
ness class B.
• To prevent fan noise being transferred to the ventila-
tion devices, silencers should be installed in the duct
system. In the event of ventilation devices in noise-
sensitive rooms, silencers must be installed.
• Ducts that may become cold must be insulated with
diffusion-proof material (at least PE30 or equivalent)
along their entire length.
• Ensure that the condensation insulation is fully sealed
at any joints and/or at lead-in nipples, silencers, roof
cowls or similar.
• A duct in a masonry chimney stack must not be used
for extract air.
• The exhaust air module must be provided with the
enclosed air filter.
EXHAUST AIR DUCT /KITCHEN FAN
Exhaust air duct (kitchen fan) must not be connected to
S135.
To prevent food vapour being transferred to S135 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 in-
stallations.
Always use a kitchen fan when cooking.
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 using
a sharp knife. The plastic is prepared for easy cut-
ting.
4. Press the filter cartridge into place in the connection
for incoming air (XL43).

INSTALL THE CONNECTOR
If a filter solution other than that enclosed is used, the
enclosed coupling must instead be mounted in the
connection for incoming air (XL43).
INSTALL THE SILENCER
1. Remove the plugs from the silencer enclosed.
2. Install the silencer in the connector for outgoing air
(XL44).

Ventilation flow
(exhaust air)
Connect S135 so that all the exhaust air, except kitchen
duct air (kitchen fan), passes through the evaporator
(EP1) in the exhaust air module.
The ventilation flow must comply with the applicable
national standards.
For the optimum exhaust air module performance, the
ventilation flow should not be less than 20 l/s (72 m³/h)
at normal exhaust air temperature. At lower exhaust air
temperatures, a higher flow is required.
The ventilation capacity is set in the indoor module’s
menu system (menu 7.1.4.1).
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.
Incorrect adjustment of the ventilation may lead to re-
duced installation efficiency and thus poorer operating
economy, and may cause moisture damage in the
building
