Transport
The supply air module must be transported and stored
dry.
Assembly
SAM 40 is mounted free-standing on brackets, alternat-
ively above a VPB 200 (for VPB 300/VPBS 300 installation
is carried out using brackets). Noise from the fan can be
transferred to the brackets.
■Install the brackets to 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 supply air
module. All service on SAM 40 can be carried out from
the front.
800
NOTE
Ensure that there is sufficient space (300 mm)
above the supply air module for installing
ventilation hoses.

Dimensioning the system
1. Work from the water temperature at DOT (DVOT).
2. Work from the current supply air flow.
3. Work from the desired supply air temperature, then
calculate the output that SAM 40 must give at DOT.
4. Determine the water flow across SAM 40 from the
correct output diagram.
NOTE
For supply temperatures that do not ap-
pear in any of the diagrams, an estimate
(linear interpolation) can be made.
5. Work from the projected pressure drop (at the pro-
jected flow) in the waterborne system that is parallel
with SAM 40.
6. Check in the pressure drop diagram that the working
point is inside the grey working range.
7. Check that the pump capacity from the heat pump
is sufficient for both the heating system and SAM
40.

Pressure drop across the
climate system
Water flow
The diagram shows the climate system’s required pres-
sure drop. The pressure drop across SAM 40 is the same
as that across the climate system that is parallel with
SAM 40.
Check that the working point is inside the grey area. If
the working point is inside the dark grey area, to the left
in the diagram, it can give rise to an oscillating supply
air temperature. If there is too low a pressure drop across
the climate system that is parallel with SAM 40, there is
a risk of ending up in the white area. In this area, there
is a risk of too low a water flow through the supply air
module and there is then a risk of freezing.
SAM 40Chapter 4 | Pipe and ventilation connections12

Installation alternative
SAM 40 can be installed in several different ways, some
of which are shown below.
More information about the options is available at
nibe.eu.

LEK
5. Secure SAM 40 with the 2 screws supplied.
LEK
6. Connect heating medium and ventilation pipes.
7. Reinstall the service cover on VPB 200.
AHPS
Caution
For connection of AHPS to F750, docking kit
SCA 42 is used.
In order to locate SAM 40 above AHPS, some conversion
of AHPS is required. See the Installer Manual for SCA 42
for more information.
13Chapter 4 | Pipe and ventilation connectionsSAM 40

Volume vessel
During hot water production and when F750 is defrost-
ing, no energy is supplied to the climate system. For this
reason, to achieve satisfactory function of the supply air
module, stored energy must be available in the climate
system during these operating cases. If there are closed
thermostat valves blocking the flow through the radiat-
ors/underfloor heating coils, the volume in these cannot
be included in the system volume.
If the total volume in the climate system (excluding the
heat pump volume) is less than 40 litres, extra system
volume, e.g. volume vessel UKV, has to be connected to
the supply line after the heat pump.
UKV
-AZ2
SAM 40
Extra climate system
In buildings with several climate systems that require
different supply temperatures, the accessory
ECS 40/ECS 41 can be connected. A shunt valve then
lowers the temperature to the underfloor heating sys-
tem, for example.
SAM 40 is connected in parallel with the extra climate
system.

SAM 40Chapter 4 | Pipe and ventilation connections14

General ventilation connection
■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 tightness
class B.
■To prevent fan noise being transferred to the ventila-
tion devices, install silencers in the ducts.
■The outdoor air duct is insulated using diffusion-proof
material (at least PE30 or equivalent) along its entire
length.
■Ensure that the condensation insulation is fully sealed
at any joints and/or at lead-in nipples, silencers, roof
cowls or similar.
■The air must be routed to the outdoor air duct through
an outer wall grille in the facade. The outer wall grille
must be installed so that it is protected from the
weather and must be designed so that no rainwater
and/or snow can penetrate the facade or follow the
air into the duct.
■When positioning the outdoor air and extract air
hood/grille, bear in mind that the two air flows must
not short circuit to prevent the extract air from being
drawn into SAM 40 again.
■When external devices that affect the ventilation are
used, for example kitchen fans and stoves, the heat
pump must be in operation. There is a risk of freezing
at low outdoor temperatures.
Ventilation flow
The supply air flow must be lower than the exhaust air
flow to prevent over pressure in the house.
Set the ventilation capacity in the heat pump’s menu
system (menu 5.1.6).
Adjusting ventilation
To obtain the necessary air exchange in every room of
the house, the exhaust air device and the supply air
device must be correctly positioned and adjusted and
the fans in the heat pump and supply air module adjus-
ted.
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

2. Set the heat pump's switch (SF1) to "".
3. Follow the instructions in the start guide in the heat
pump display. If the start guide does not start when
you start the heat pump, start it manually in menu
5.7.
Commissioning with a compatible heat pump
The first time the installation is started a start guide is
started. The start guide instructions state what needs to
carried out at the first start together with a run through
of the installation’s basic settings.
The start guide ensures that start-up is carried out cor-
rectly and cannot be bypassed.The start guide can be
started later in menu 5.7.
Caution
As long as the start guide is active, no function
in the installation will start automatically.
The guide will appear at each installation re-
start until it is deselected on the last page.
Setting the ventilation
Ventilation must be set according to applicable stand-
ards. The supply air flow is adjusted to approx. 80% of
the exhaust air flow. The setting is made in menu 5.1.6.
Even if ventilation is roughly set at installation it is import-
ant that a ventilation adjustment is ordered and permit-
ted.

In most cases, the heat pump notes operational interfer-
ence (operational interference can lead to disturbance
in comfort) and indicates this with alarms and shows
action instructions in the display.
Info-menu
All the heat pump measurement values are gathered
under menu 3.1 in the heat pump menu system. Looking
through the values in this menu can often simplify find-
ing the source of the fault. See help menu or user
manual for more information about menu 3.1.

Low pressure alarm
alarm
In the event of an alarm, some kind of malfunction has
occurred, which is indicated by the status lamp changing
from green continuously to red continuously. In addition,
an alarm bell appears in the information window.
Alarm
In the event of an alarm with a red status lamp a malfunc-
tion has occurred that the heat pump cannot remedy
itself. In the display, by turning the control knob and
pressing the OK button, you can see the type of alarm it
is and reset it. You can also choose to set the heat pump
to aid mode.
info / action Here you can read what the alarm means
and receive tips on what you can do to correct the
problem that caused the alarm.
reset alarm In most cases it is sufficient to select "reset
alarm" to correct the problem that caused the alarm. If
a green light comes on after selecting "reset alarm", the
alarm has been remedied. If a red light is still visible and
a menu called "alarm" is visible in the display, the prob-
lem causing the alarm remains. If the alarm disappears
and then returns, see the troubleshooting section (page
Troubleshooting).
aid mode ”aid mode” is a type of emergency mode. This
means that the heat pump produces heat and/or hot
water despite there being some kind of problem. This
can mean that the heat pump's compressor is not run-
ning. In this case the immersion heater produces heat
and/or hot water.
NOTE
To select aid mode an alarm action must be
selected in the menu 5.1.4.
Caution
Selecting "aid mode” is not the same as correct-
ing the problem that caused the alarm. The
status lamp will therefore continue to be red.
Troubleshooting
If the operational interference is not shown in the display
the following tips can be used:
