SAM 41Chapter 1 | Important information6

TransportThe supply air module must be transported and storeddry.

AssemblySAM 41 is mounted free-standing on brackets Noisefrom the fan can be transferred to the brackets.■ Install the brackets to anoutsidewall, ideally in a roomwhere noise does not matter, in order to eliminatenoise problems. If this is not possible, avoid placing itagainst awall behindabedroomorother roomwherenoise may be a problem.

■ Wherever the unit is located, walls to sound sensitiverooms should be fitted with sound insulation.

■ Route pipes so they are not fixed to an internal wallthat backs on to a bedroom or living room.

Installation areaLeave a free space of 800 mm in front of the supply airmodule. All service on SAM 41 can be carried out fromthe front.

Heating medium sideDuring hot water production andwhen F750 is defrost-ing, no energy is transferred to the climate system.Therefore, for full function of the supply air module, thestored energy must be available in the climate systemduring these operating cases. Energy is stored in the cli-mate system'swater volume. For full functionof SAM41the waterborne climate system (including the internalvolume in F750) must have a total water volume of atleast 95 litres. If this volume requirement is not met, thesystem volume is increased with volume vessel (NIBEUKV).

Dimensioning the system1. 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 41must give at DUT.4. Determine the water flow across SAM 41 from the

correct output diagram.NOTE! For supply temperat-ures that are not in oneof thediagrams, an estimate(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 thepressuredropdiagram that theworkingpoint is inside the grey working range.

7. Check that thepumpcapacity fromF750 is sufficientfor both the heating system and SAM 41.

NOTE

If information regarding the present flow ismissing in the diagram there is a risk of frostdamage to the supply air coil.

Required system pressure drop

The diagram shows the climate system's required pres-sure drop. Note that the pressure drop across SAM 41 isthe same as that across the climate system 1.

Check that the working point is inside the grey range. Ifthe working point is inside the darker grey range to theleft in the diagram, it can give an oscillating supply airtemperature. At too lowpressuredropacross the climatesystem 1, one risks falling within the white area. In thisrange, there is a risk of too low water flow through thesupply air module and there is a risk of freezing.

NOTE

Venting may be necessary on installation andafter a period of use. Vent through vent valve(QM20).

General ventilation connectionVentilation installationmust be carriedout in accordancewith current norms and directives.

To prevent fan noise being transferred to the supply airdevices, install a silencer in the duct. This is especiallyimportant if there are supply air inlets in bedrooms.

Connectionsmustbemadevia flexiblehoses,whichmustbe installed so that they are easy to replace. The airshould be routed to the outdoor air duct through anoutside wall grille in the facade. The outer wall grillemust be installed protected from theweather andmustbe designed so that no rain water can penetrate thefacade or follow the air into the duct. The outdoor airduct must be provided with diffusion-tight insulationover its entire length. Ensure that the condensation insu-lation is sealed at any joints and/or at lead-in nipples,silencers, roof cowls or similar.

Provision must be made for inspection and cleaning oftheduct.Make sure that there are no reductions in cross-sectional area in the form of creases etc., since this willreduce the ventilation capacity. The air duct systemmustbe a minimum of air tightness class B.

When external devices that affect the ventilation areused, for example kitchen fans and stoves, ensure thatthe heat pump is operating. A heat pump that isswitched off does not heat the supply air module andthere is risk of freezing at low outdoor temperatures.

The frost protectionmust bedimensioned to seal againsttheunderpressure that canbe created in thehousewhena fire is lit in the stove when the supply air fan and heatpump are switched off. An external supply air duct forthe stove is recommended.

Outdoor air

NOTE

External frost protectionmust be installed in theoutdoor air duct.

Ventilation flowThe supply air flow must be lower than the exhaust airflow to prevent over pressure in the house.

Ensure that the ventilation openings are not blocked.Set the ventilation capacity in the heat pump's menusystem (menu 5.1.6).

Adjusting ventilationTo obtain the necessary air exchange in every room ofthe house, the exhaust air device and the supply airdevice must be correctly positioned and adjusted andthe fans in the heat pump and supply air module adjus-ted.

Immediately after installation adjust the ventilation sothat it is set according to the projected value of thehouse.

A defective ventilation installation may lead to reducedinstallation efficiency and thus poorer operating eco-nomy, andmay result inmoisture damage to the house.


GeneralAll electrical equipment is connected at the factory.■ Disconnect SAM41before insulation testing thehousewiring.

■ For the supply air module wiring diagram, see page24.

■ Signal cables to external connectionsmust not be laidclose to high current cables.

■ If the supply cable is damaged, only NIBE, its servicerepresentativeor similar authorisedpersonmay replaceit to prevent any danger and damage.

NOTE

Electrical installation and servicemust be carriedout under the supervision of a qualified electri-cian. Electrical installation and wiring must becarried out in accordance with the stipulationsin force.

Connections

Connecting to F750This section describes the electrical connection for con-trolling SAM 41 from NIBE F750.

The heat pump switch must be moved to position " "and the switch (SF1) on SAM41 toposition0, before anywork can be started.1. Ensure that the products are completely disconnec-

ted from the power source. Remove the front hatchand protective cover to the input card on the heatpump according to the instructions in its Installer'smanual.

2. Connect cable W102 to position X4 on the inputboard (AA3) in the heat pump according to thewir-ing diagramonpage 24. Use the cable lead-in in theheat pump when routing cables.

If several accessories are to be connected or arealready installed, the adjacent wiring diagrammustbe followed.

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.

Preparations1. Check that the switch (SF1) for F750 is in position

"2. Check that the filling valves (QM10) and (QM11) in

the heat pump are fully closed.

Connecting toheatingmediumsystem1. Connect SAM 41 according to the outline diagram

on page 10.2. Fill with water using the filler valve (QM11) in F750.3. Vent the heating medium system with the vent

valves (QM20) above SAM 41, and the vent valvesin F750 and fill if necessary using the filler valve(QM11) in F750.

Start-up and inspectionCaution

Check theminiature circuit-breaker (FA1) in theheatpump. Itmayhave trippedduring transport-ation.

Setting the ventilationVentilation must be set according to applicable stand-ards. The supply air flow is adjusted so that it is 80% ofthe 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.

NOTE

Order a ventilation adjustment to complete thesetting.

In most cases, the heat pump F750 notes operationalinterference (operational interference can lead to dis-turbance in comfort) and indicates this with alarms andshows action instructions in the display.

Info menuAll the heat pump measurement values are gatheredundermenu3.1 in theheat pumpmenu system. Lookingthrough the values in this menu can often simplify find-ing the source of the fault. See help menu or usermanual for more information about menu 3.1.

alarm

In the event of an alarm, some kind of malfunction hasoccurred,which is indicatedby the status lamp changingfromgreen continuously to red continuously. In addition,an alarm bell appears in the information window.

AlarmIn theeventof analarmwith a red status lampamalfunc-tion has occurred that the heat pump cannot remedyitself. In the display, by turning the control knob andpressing the OK button, you can see the type of alarm itis and reset it. You can also choose to set the heat pumpto aid mode.

info / action Here you can read what the alarm meansand receive tips on what you can do to correct theproblem that caused the alarm.

reset alarm In most cases it is enough to select "resetalarm" to correct the problem that caused the alarm. Ifa green light illuminates after selecting "reset alarm" thealarm has been remedied. If a red light is still visible anda menu called ”alarm” is visible in the display, the prob-lem that caused the alarm remains. If the alarm disap-pears and then returns, see the troubleshooting section(page 18).

aidmode ”aidmode” is a type of emergencymode. Thismeans that the heat pump produces heat and/or hotwater despite there being some kind of problem. Thiscan mean that the heat pump's compressor is not run-ning. In this case the immersion heater produces heatand/or hot water.

NOTE

To select aid mode an alarm action must be se-lected in the menu 5.1.4.

Caution

Selecting "aidmode” is not the same as correct-ing the problem that caused the alarm. Thestatus lamp will therefore continue to be red.

TroubleshootingIf theoperational interference is not shown in thedisplaythe following tips can be used:

Basic actionsStart by checking the following possible fault sources:■ That theheat pump is runningor that the supply cableto SAM 41 is connected.

■ Group and main fuses of the accommodation.

■ The property's earth circuit breaker.

■ The heat pump's miniature circuit breaker (FA1).

■ The heat pump's temperature limiter (FD1).

■ Correctly set load monitor (if installed).

Low hot water temperature or a lack of hotwater■ The heat pump has temporarily prioritised supply airventilation to prevent too low temperatures in thesupply air coil.

Low room temperature■ Air in the heating medium system.– Vent SAM 41 using vent valve (QM20).

■ Incorrect value set in supply air automatic control sys-tem.– Enter menu 5.3.9 (ext sup air md) and adjust thesetting for the supply air temperature.

High room temperature■ Incorrect value set in supply air automatic control sys-tem.– Enter menu 5.3.9 (ext sup air md) and adjust thesetting for the supply air temperature.

Low or a lack of ventilation■ Filter (HQ11) blocked.– Clean or replace the filter.

■ The ventilation is not adjusted.– Order/implement ventilation adjustment.

■ Supply air device closed, blocked or throttled downtoo much.– Check and clean the supply air device.

■ Check external frost protection.
