SAM 40Chapter 1 | Important information4

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 with the help of brackets). Noise from the fan can be
transferred to the brackets.
႑Install the brackets to an outside wall, ideally in a
room where noise does not matter, in order to elim-
inate 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.
႑Wherever the unit is located, walls to sound sensitive
rooms should be fitted with sound insulation.
႑Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
Installation area
Leave a space of 500 mm in front of the supply air mod-
ule. All service on SAM 40 can be carried out from the
front.
500
NOTE
Ensure that there is sufficient space (300 mm)
above the supply air module for installing ventil-
ation hoses.
Removing the covers
Front cover
1. Remove the service cover by pulling it straight out.

If several climate systems (ECS 40/ECS 41) are
present, SAM 40 must be connected in parallel
with climate system 1.

SAM 40Chapter 4 | Pipe and ventilation connections10

Heating medium side
A water borne climate system with a volume of at least
20 litres must be present for installation of SAM 40 to
be possible. For correct function of SAM 40 the total
volume of the climate system (excluding the internal
volume in F750) must exceed 40 litres. This means that
if the volume of the climate system does not exceed 40
litres installation of buffer vessel (NIBE UKV) is necessary.
Dimensioning the system
1. Work from the water temperature at DUT (DVUT).
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 DUT.
4. Determine the water flow across SAM 40 from the
correct output diagram. NOTE! For flow line temper-
atures that are not in one of the diagrams, an estim-
ate (linear interpolation) can be carried out.
5. Work from the projected pressure drop (at the pro-
jected flow) in the water borne system, climate sys-
tem 1.
6. Check in the pressure drop diagram that the working
point is inside the grey working area.

The diagram shows pressure drop across SAM 40 during
different water flows. Note that the pressure drop is the
same as that which affects the climate system 1.
Check that the working point is inside the grey working
area. If the working point is inside the darker grey area
to the left of the diagram, it can give an oscillating supply
air temperature.
NOTE
Venting may be necessary on installation and
after a period of use. Vent through venting valve
(QM20).
13Chapter 4 | Pipe and ventilation connectionsSAM 40

General ventilation connection
Ventilation installation must be carried out in accordance
with current norms and directives.
To prevent fan noise being transferred to the supply air
devices, it may be a good idea to install a silencer in the
duct. This is especially important if there are supply air
devices in bedrooms.
Connections must be made via flexible hoses, which must
be installed so that they are easy to replace. The outdoor
air duct must be provided with diffusion-tight insulation
over its entire length. Provision must be made for inspec-
tion and cleaning of the duct. Make sure that there are
no reductions of cross-sectional area in the form of
creases, tight bends etc, since this will reduce the ventil-
ation capacity. The air duct system must be a minimum
of air tightness class B.

Ventilation flow
Ensure that the ventilation openings are not blocked. Set
the ventilation capacity in the heat pump's menu system
(menu 5.1.5).
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 adjusted.
The factory setting for the ventilation on the supply air
module is high and you should therefore adjust the
ventilation immediately after installation so that it is set
according to the projected value for the house.
A defective ventilation installation may lead to reduced
installation efficiency and thus poorer operating economy,
and may result in moisture damage to the house.

General
All electrical equipment is connected at the factory.
႑Disconnect SAM 40 before insulation testing the
house wiring.
႑For the supply air module wiring diagram, see page
24.
႑Signal cables to external connections must not be laid
close to high current cables.
႑If the supply cable is damaged, only NIBE, its service
representative or similar authorised person may re-
place it to prevent any danger and damage.
NOTE
Electrical installation and service must be carried
out under the supervision of a qualified electri-
cian. Electrical installation and wiring must be
carried out in accordance with the stipulations
in force.
Connections
Connecting to F750
This section describes the electrical connection for con-
trolling SAM 40 from NIBE F750.
The heat pump switch must be in the ” ” and SAM 40's
switch in 0position before commencing work.
1. Ensure that the products are completely disconnected
from the power source. Remove the front hatch and
protective cover to the input card on the heat pump
according to the instructions in its Installer's manual.
2. Connect cable W102 to position X4 on the input
card in the heat pump, according to the wiring dia-
gram on page 24. Use the cable lead-in in the heat
pump when cable routing.
If several accessories are to be connected or are
already installed, the adjacent wiring diagram must
be followed.
The first accessory card must be connected directly
to the heat pump's terminal block AA3-X4. The fol-
lowing cards must be connected in series with the
previous card.
3. Fix external cable routing.
4. Install the protective cover and the service cover ac-
cording to the heat pump Installation manual.
5. Connect plug W101.

Preparations
1. Check that the switch (SF1) in F750 is in position
"".
2. Check that the filling valves (QM10) and (QM11) in
the heat pump are fully closed and that the temper-
ature limiter (FD1) has not deployed.
Caution
Check the temperature limiter (FD1) and mini-
ature circuit-breaker (FA1) in the heat pump.
They may have tripped during transportation.
Connecting to heating medium
system
1. Connect SAM 40 according to the outline diagram
on page 9.
2. Fill with water using the filler valve (QM11) in F750.
3. Vent the heating medium system with the vent valves
(QM20) above SAM 40, and the vent valves in F750
and fill if necessary using the filler valve (QM11) in
F750.

Start-up and inspection
Start-up
NOTE
There must be water in the climate system be-
fore the switch in F750 is set to " ".
NOTE
In low outdoor temperatures there is a risk of
SAM 40 freezing.
1. Set switch (SF1) on SAM 40 in position "1".
2. Turn 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
The first time the heat pump 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 heat pump’s basic settings.
The start guide ensures that the start-up is carried out
correctly 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 heat pump will start automatically.
The guide will appear at each heat pump restart
until it is deselected on the last page.
