Safety precautions

Caution

Install the system in full accordance with this installation

manual.

Incorrect installation can cause bursts, personal injury, water leaks,

refrigerant leaks, electric shocks and fire.

Observe the measurement values before working on the

cooling system, especially when installing in small rooms, so

that the limit for the refrigerant's density is not exceeded.

Consult an expert to interpret the measurement values. If the refri-

gerant density exceeds the limit, lack of oxygen can occur in the

event of any leak, which can cause serious accidents.

Use original accessories and the stated components for the

installation.

If parts other than those stated by us are used, water leaks, electric

shocks, fire and personal injury may occur as the unit may not work

properly.

Ventilate the working area well – refrigerant leakage may

occur during service work.

If the refrigerant comes into contact with naked flames, poisonous

gas is created.

Install the unit in a location with good support.

Unsuitable installation locations can cause the unit to fall and cause

material damage and personal injury. Installation without sufficient

support can also cause vibrations and noise.

Ensure that the unit is stable when installed, so that it can

withstand earthquakes and strong winds.

Unsuitable installation locations can cause the unit to fall and cause

material damage and personal injury.

The electrical installation must be carried out by a qualified

electrician and the system must be connected as a separate

circuit.

Power supply with insufficient capacity and incorrect function can

cause electric shocks and fire.

Use the stated cables for the electrical connection, tighten

the cables securely in the terminal blocks and relieve the

wiring correctly to prevent overloading the terminal blocks.

Loose connections or cable mountings can cause abnormal heat

production or fire.

Check, after completed installation or service, that no refriger-

ant leaks from the system in gas form.

If refrigerant gas leaks into the house and comes into contact with

an aerotemp, an oven or other hot surface, poisonous gases are

produced.

Use types of pipe and tools stated for this type of refrigerant.

Using existing parts for other refrigerants can cause breakdowns

and serious accidents due to process circuit bursts.

Switch off the compressor before opening/breaching the re-

frigerant circuit.

If the refrigerant circuit is breached /opened whilst the compressor

is running, air can enter the process circuit. This can cause unusually

high pressure in the process circuit, which can cause bursts and

personal injury.

Switch off the power supply in the event of a service or in-

spection.

If the power supply is not shut off, there is a risk of electric shocks

and damage due to the rotating fan.

Do not run the unit with removed panels or protection.

Touching rotating equipment, hot surfaces or high voltage parts

can cause personal injury due to entrapment, burns or electric

shocks.

Cut the power before starting electrical work.

Failure to cut the power can cause electric shocks, damage and in-

correct function of the equipment.

Care

Carry out the electrical installation with care.

Do not connect the ground lead to the gas line, water line, lightning

conductor or telephone line's ground lead. Incorrect grounding can

cause unit faults such as electric shocks due to short-circuiting.

NIBE™ F1345Chapter 1 | Important information2

1 Important information

Use main switch with sufficient breaking capacity.

If the switch does not have sufficient breaking capacity, malfunctions

and fire can occur.

Always use a fuse with the correct rating in the locations

where fuses are to be used.

Connecting the unit with copper wire or other metal thread can

cause unit breakdown and fire.

Cables must be routed so that they are not damaged by

metal edges or trapped by panels.

Incorrect installation can cause electric shocks, heat generation and

fire.

Do not install the unit in close proximity to locations where

leakage of combustible gases can occur.

If leaking gases collect around the unit, fire may occur.

Do not install the unit where corrosive gas (for example ni-

trous fumes) or combustible gas or steam (for example thinner

and petroleum gases) can build up or collect, or where

volatile combustible substances are handled.

Corrosive gas can cause corrosion to the heat exchanger, breaks in

plastic parts etc. and combustible gas or steam can cause fire.

Do not use the unit for specialist purposes such as for storing

food, cooling precision instruments, freeze-conservation of

animals, plants or art.

This can damage the items.

Do not install and use the system close to equipment that

generates electromagnetic fields or high frequency harmonics.

Equipment such as inverters, standby sets, medical high frequency

equipment and telecommunications equipment can affect the unit

and cause malfunctions and breakdowns. The unit can also affect

medical equipment and telecommunications equipment, so that it

functions incorrectly or not at all.

Take care when carrying the unit by hand.

If the unit weights more than 20 kg, it must be carried by two

people. Use gloves to minimize the risk of cuts.

Dispose of any packaging material correctly.

Any remaining packaging material can cause personal injury as it

may contain nails and wood.

Do not touch any buttons with wet hands.

This can cause electric shocks.

Do not touch any refrigerant pipes with your hands when

the system is in operation.

During operation the pipes become extremely hot or extremely cold,

depending on the method of operation. This can cause burn injuries

or frost injuries.

Do not shut off the power supply immediately after operation

has start.

Wait at least 5 minutes, otherwise there is a risk of water leakage

or breakdown.

Do not control the system with the main switch.

This can cause fire or water leakage. In addition, the fan can start

unexpectedly, which can cause personal injury.

Especially for units intended for R410A

- Only use R410A refrigerant. R410A means that the pressure is

about 1.6 times as high as conventional refrigerants.

- The filling connections on units with R410A are different sizes, to

prevent the system being filled with the incorrect refrigerant by

mistake.

- Do not use charging bottles. These types of bottles change the

composition of the refrigerant, which makes the performance of

the system worse.

- When filling refrigerant, the refrigerant must always leave the

bottle in liquid form.

Serial number

The serial number can be found at the bottom right of

the front cover and in the info menu (menu 3.1).

Caution

Always give the product's serial number (14 di-

gits) when reporting a fault.

Transport

F1345 should be transported and stored vertically in a

dry place. When being moved into a building, the heat

pump may be tilted back 45 °. NOTE! The heat pump is

top heavy.

If the cooling modules are pulled out and transported

upright, F1345 can be transported on its back.

NOTE

Ensure that the heat pump cannot fall over

during transport.

TIP

The side panels can be removed for easier install-

ation in the building.

Lift from the street to the set up location

If the base allows, the simplest thing is to use a pallet

truck to move the F1345 to the set up location.

NOTE

The centre of gravity is offset to one side (see

print on the packaging).

LEK

If F1345 needs to be transported across soft ground, such

as a lawn, we recommend that a crane is used that can

lift the unit to the installation location. When F1345 is

raised using a crane, distribute the load according to the

instructions on the packaging.

If a crane cannot be used F1345 can be transported on

a sack truck. F1345 must be taken from its heaviest side

(see printed material on packaging for where the centre

of gravity is) and two people are required to lift F1345.

Lift from the pallet to final positioning

Before lifting, remove the packaging and the load anchor

to the pallet as well as front and side panels.

Before lifting, the heat pump must be separated by

pulling the cooling modules out from the cabinet. See

the service chapter in the operating manual for instruc-

tions about the separation.

Carry the heat pump by the upper cooling module's slide

rails, use gloves.

NOTE

The heat pump must not be moved when only

the lower cooling module has been pulled out.

If the heat pump is not secured in position the

upper cooling module must always be removed

before the lower one can be pulled out.

Scrapping

For scrapping, remove the product in reverse order.

NIBE™ F1345Chapter 2 | Delivery and handling6

2 Delivery and handling

Assembly

႑Position F1345 on a firm base that can take the weight,

preferably on a concrete floor or foundation. Use the

product's adjustable feet to obtain a horizontal and

stable set-up.

30 - 50 mm

႑The area where F1345 is located must be equipped

with floor drainage.

႑Install with its back 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.

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 800 mm in front of the product. Approx

50 mm free space is required in order to open the side

hatches. The hatches do not need to be opened during

service, all service on F1345 can be carried out from the

front. Leave space between the heat pump and wall be-

hind (and any routing of supply cables and pipes) to re-

duce the risk reproduction of any vibration.

General

Pipe installation must be carried out in accordance with

current norms and directives. F1345 can operate with a

return temperature of up to 58 °C and an outgoing

temperature from the heat pump of 65 °C.

F1345 is not equipped with internal shut off valves; these

must be installed to facilitate any future servicing.

NOTE

The pipe system needs to be flushed out before

the heat pump is connected so that debris can-

not damage component parts.

NOTE

Do not solder directly on the heat pump pipes,

because of internal sensors.

Compression ring coupling alternatively pressure

connection should be used.

System diagram

F1345 consists of two heat pump modules, circulation

pumps and control system with possibility of additional

heat. F1345 is connected to the brine and heating medi-

um circuits.

In the heat pump evaporator, the brine (water mixed with

anti-freeze, glycol or ethanol) releases its energy to the

refrigerant, which is vaporised in order to be compressed

in the compressor. The refrigerant, of which the temper-

ature has now been raised, is passed to the condenser

where it gives off its energy to the heating medium circuit

and, if necessary, to any docked water heater. If there is

a greater need for heating/hot water than the com-

pressors can provide it is possible is to connect an external

immersion heater.

Applies to PEM hose 40x2.4 PN 6.3.

These are rough example values. At installation the correct

calculations must be made according to local conditions.

Caution

The length of the collector hose varies depend-

ing on the rock/soil conditions, climate zone and

on the climate system (radiators or underfloor

heating).

Max length per coil for the collector should not exceed

500 m.

The collectors must always be connected in parallel with

the possibility of adjusting the flow for the relevant coil.

For surface soil heat, the hose should be buried at a depth

determined by local conditions and the distance between

the hoses should be at least 1 metre.

For several bore holes, the distance between the holes

must be determined according to local conditions.

Ensure the collector hose rises constantly towards the

heat pump to avoid air pockets. If this is not possible,

airvents should be used.

As the temperature of brine system can fall below 0 °C

it must be protected against freezing down to -15 °C. 1

litre of ready mixed brine per meter of collector hose

(applies when using PEM-hose 40x 2.4 PN 6.3) is used as

a guide value when making the volume calculation.

Caution

Because the temperature of the brine system

varies depending on the heat source, the menu

5.1.7 "br pmp al set." must be set to the suit-

able value.

Connecting the brine side

႑The pipe connections are on the rear of the heat pump.

႑Insulate all indoor brine pipes against condensation.

NOTE

Condensation may drip from the expansion

vessel. Position the vessel so that this does not

harm other equipment.

Caution

When necessary you should install venting valves

in the brine system.

႑Mark the brine system with the antifreeze that is used.

႑Install the supplied safety valve at the expansion vessel

as illustrated in the outline diagram. The entire length

of the overflow water pipe from the safety valves must

be inclined to prevent water pockets and must also be

frost-free.

႑Install shut off valves as close to the heat pump as

possible so that the flow to individual cooling modules

can be shut off. Extra safety valves between the particle

filter and shut off valves (according the outline diagram)

are required.

႑Fit the supplied particle filter on the incoming pipe.

႑Fit the supplied non-return valves on the outgoing pipe.

In the case of connection to an open groundwater system,

an intermediate frost-protected circuit must be provided,

because of the risk of dirt and freezing in the evaporator.

This requires an extra heat exchanger.

Connecting external brine pump (40 and

60kW only)

Install the brine pump (GP16) according to the circulation

pump manual for connection of incoming brine (EP14-

XL6) and (EP15-XL6) between the heat pump and shut

off valve (see image).

In some countries the brine pump is not supplied, see list

of supplied items.

NOTE

Insulate the brine pump against condensation

(do not cover the drainage hole).

Expansion vessel

The brine circuit must be supplied with a pressure expan-

sion vessel.

The brine side must be pressurised to at least 0.05 MPa

(0.5 bar).

The pressure expansion vessel should be dimensioned as

set out in the following diagram, to prevent operating

disturbances. The diagrams cover the temperature range

from 10 °C to +20 °C at a pre-pressure of 0.05 MPa (0.5

bar) and the safety valve's opening pressure of 0.3 MPa

(3.0 bar).

Ethanol 28% (volume percent)

In installations with ethanol (28% volume percent) as the

brine the pressure expansion vessel must be dimensioned

according to the following diagram.

Heating medium side

Connecting the climate system

A climate system is a system that regulates indoor comfort

with the help of the control system in F1345 and for ex-

ample radiators, underfloor heating/cooling, fan con-

vectors etc.

႑The pipe connections are on the rear of the heat pump.

႑Install the necessary safety equipment and shut off

valves (installed as close to the heat pump as possible

so that the flow to individual cooling modules can be

shut off).

႑Fit the supplied particle filter on the incoming pipe.

႑The safety valve must have a maximum 0.6 MPa (6.0

bar) opening pressure and be installed on the heating

medium return. The entire length of the overflow water

pipe from the safety valves must be inclined to prevent

water pockets and must also be frost-free.

႑When connecting to a system with thermostats on all

radiators, a relief valve must be fitted, or some of the

thermostats must be removed to ensure sufficient flow.

႑Fit the supplied non-return valves on the outgoing pipe.

Caution

When necessary you should install venting valves

in the climate system.

Caution

The heat pump is designed so that heating pro-

duction can occur with one or two cooling

modules. This however entails different pipe or

electrical installations.

Hot water heater

Connecting the hot water heater

႑Any docked hot water heater must be fitted with ne-

cessary set of valves.

႑The mixing valve must be installed if the setting is

changed so that the temperature can exceed 60 °C.

႑The setting for hot water is made in menu 5.1.1.

႑The safety valve must have a maximum opening pres-

sure in accordance with the water heater manual and

be installed on the incoming domestic water line. The

entire length of the overflow water pipe from the safety

valves must be inclined to prevent water pockets and

must also be frost-free.

Caution

Hot water production is activated in menu 5.2

or in the start guide.

Caution

The heat pump/system is designed so that hot

water production can occur with one or several

cooling modules. This however entails different

pipe or electrical installations.

Fixed condensing

If F1345 is to work with fixed condensing you must con-

nect an external flow sensor (BT25) according to the de-

scription on page 23. In addition, you must do the follow-

ing menu settings.
