For Home Owners
General
General
SPLIT is a system for heating, cooling and producing hot water for small houses. The system consists of an outdoor module
(L8 SPLIT/L12 SPLIT), which utilises the energy in the outdoor air and sends it to the indoor module (HM 8-12 SPLIT), which
takes care of the regulation and heat distribution in the house.
In order to gain the greatest benefit from the SPLIT system, please refer to the 'For Home Owners' chapter within this Installation and Maintenance Manual.
SPLIT is a quality system offering a long service life and reliable operation.

Product information
System heating (cooling) and hot water
SPLIT is a complete modern heat pump system that offers
effective energy saving and reduced carbon dioxide
emissions.
Klimatsystem
Climate
system
The heat is retrieved from the outdoor air by an outdoor
module (L8 SPLIT/L12 SPLIT), where the refrigerant, which
circulates in a closed system, transfers the heat from the
heat source (outdoor air) to the indoor module (HM 8-12
SPLIT). This eliminates the need for boreholes and coils in
the ground.

Prepared for control of two climate systems.
Integrated active cooling function.
Possible to connect external heat sources.
Function
SPLIT is a system that can produce heating, hot water and
cooling.
The principle during heating can be simplified as follows:
1. The refrigerant in L8 SPLIT/L12 SPLIT retrieves heat
from the outdoor air then compresses it, which increases the temperature further.
2. The hot refrigerant (now in gas state) is routed into
HM 8-12 SPLIT.
3. The refrigerant releases the heat for further distribution in the system.
4. The refrigerant (now in liquid state) is routed back to
L8 SPLIT/L12 SPLIT and the process is repeated.
Principle of operation SPLIT
System without hot water, only heating (cooling)
Climate
system
Klimatsystem
By reversing the process, thereby allowing the refrigerant
in L8 SPLIT/L12 SPLIT to retrieve the heat from the water
and release it into the outdoor air, the heat pump can, if
necessary, cool instead.

as well as control computer instructions such as comfort
etc. that you require the heat pump system to fulfil.
In order for the installation to be used optimally, certain
basic settings must have been made (see page 9). In addition the installation in general must be carried out according to the instructions and manufacturer's recommendations.
Menu 1.0 (temperature in the water heater) is normally
shown on the display.
The plus and minus buttons and the enter button
are used to scroll through the menu system as well
as to change the set value in some menus.
Menu types
Control is divided into different menu types depending
on how ”deep” into the controls you need to go.

For Home Owners
Comfort setting heating
Comfort setting heating
■ HM 8-12 SPLIT selects operating mode automatic
General
The indoor temperature depends on several factors.
■ Sunlight and heat emissions from people and household
machines are normally sufficient to keep the house warm
during the warmer parts of the year.
■ When it gets colder outside, the climate system must be
started. The colder it is outside, the warmer radiators
and under floor heating systems must be.
3.
Controlling heat production
Normally, the heat pump heats the water (heating medium) to the temperature required at a certain outdoor
temperature. This occurs automatically on the basis of the
collected temperature values from the outdoor temperature sensor and sensors on the lines to the climate system
(flow line sensors). Extra accessories such as room temperature sensors, can influence the temperature.
4.
However, the correct default settings must be made on
the heat pump first, see the section “Default settings”.
The temperature information that the outdoor sensor
(mounted on an exterior wall of the house) sends to the
heat pump’s control computer senses variations in the
outdoor temperature early on. It does not have to be cold
inside the house before the control system is activated, as
soon as the average outdoor temperature drops outside,
the temperature of the water to the climate system (supply
temp.) inside the house is increased automatically.
5.
The heat pump's supply temperature (menu 2.0) will hover
around the theoretical required value, which is in brackets
on the display.
7.
6.
* To use the cooling functions, the system must be constructed to withstand low temperatures and "Cooling"
must be activated in menu 9.3.3.
Temperature of the climate system
The temperature of the climate system in relation to the
outdoor temperature can be modified by using the "Offset
heating curve” knob on the heat pump’s front panel.
Changing the room temperature manually
If you want to temporarily or permanently increase or
lower the indoor temperature turn the ”Offset heating
curve” knob clockwise or anticlockwise. One line approximately represents a 1 degree change in room temperature.
Operating status
The “Operating mode” button is used to set the required operating mode with regard to permitting/blocking the circulation pump and additional energy.
NOTE
The change does not need to be confirmed with the
enter button.
An increase in the room temperature may be inhibited by the radiator or underfloor heating thermostats, if so these must be turned up.
The current operating mode is shown on the front panel
display when the button is pressed and the mode changes
when you continue to press the button.
The display returns to the normal display mode once the
enter button is pressed.
The addition is only used for anti-freeze mode, if it is deactivated in the menu system. This applies to all operating
modes.
The different operating modes are:
1. ”Auto”
■ HM 8-12 SPLIT automatically selects the operating
mode by taking the outdoor temperature into account. This means that the operating mode switches
between "Heating" and "Hot water". Current operating mode is shown within brackets.
■ The circulation pump is permitted to operate when
there is a need.
”AutoK”*
2.
8
(cooling can also be selected now) with regard to
the outdoor temperature. This means that the operating mode switches between "Heating", "Cooling"
and "Hot water".
■ The circulation pump is permitted to operate when
there is a need.
"Heat" / "Heat addition"
■ Only heating and cooling produced.
■ The circulation pump is in operation the entire time.
■ If "Heat addition" is shown the addition is permitted
to operate if necessary.
"Cooling"* / "Super cooling"
■ If addition is permitted, "Super cooling" is displayed.
The compressor then only runs in cooling mode.
Otherwise, the mode switches to cooling or producing hot water.
■ The circulation pump is in operation the entire time.
■ Hot water is only produced by the immersion heater.
"Hot water"
■ Only hot water is produced.
■ Only the compressor is operational.
”Add. heat only”
■ Compressor blocked. The function is activated by
pressing in the ”operating mode button” for 7
seconds.
Deactivate the function by pressing the "Operating
mode" button for 7 seconds once again.

Comfort setting cooling
General
Controlling cooling mode using the room
sensor
The condition in order for cooling to be activated is that
"On" is selected in menu 9.3.3 Cooling system.
The climate system must manage cooling operation.
Settings must be made by the installer when commissioning the system.
If RFV SPLIT is present, the condition for cooling is that the
room temperature has exceeded the set room temperature
(menu 6.3) by the set value in menu 8.2.5 and that the
outdoor temperature is equal to or exceeds the set outdoor
temperature value (menu 8.2.4).
If a room sensor is connected, it starts and stops cooling
together with the outdoor temperature. The lowest current
supply temperature is set in menu 2.2.4.
When the room temperature has dropped below the set
room temperature in menu 6.3 by the set value in menu
8.2.5 or the outdoor temperature falls below the set value
in menu 8.2.4 by the set value in menu 8.2.5, cooling
switches off.
NOTE
Cooling operated from the outdoor sensor in
operating mode AutoK
If the cooling system is set to "On" in menu 9.3.3 and the
outdoor temperature is greater or equivalent to the set
start temperature for cooling in menu 8.2.4, cooling starts.
Cooling stops when the outdoor temperature drops below
the set value minus the set value in menu 8.2.5.
The current supply line temperature is determined from
the selected cooling curve in menu 2.2.2 and the offset
for cooling curve, menu 2.2.1. Limitations, which are not
in the diagram, are included in the control system's permitted min temperature.

BP5
The climate system's safety valve (FL2) is close to EHZK 90
SPLIT or by the hot water tank. See illustration.
The climate system's safety valve (FL2) must be completely
sealed. Checks must be carried out regularly as follows:
■ Open the valve.
■ Check that water flows through the valve. If this does
not happen, replace the safety valve.
■ Close the valve again.
■ The climate system may need to be refilled after checking
the safety valve, see the section “Filling the climate system”. Contact your installer for refilling the climate system.
Safety valve domestic water
The safety valve for domestic water sometimes releases a
little water after hot water has been tapped. This is because the cold water, which enters the heater to replace
the hot water, expands when heated causing the pressure
to rise and the safety valve to open.
Also check the safety valve for domestic water regularly.
The appearance and location of the safety valve differs
between different installations. Follow the cold water pipe
to locate the safety valve. Contact your installer for information.

Maintenance
Emptying the coil in the water heater
The water heater is of the coil type and the pressure in the
domestic coil can be released by closing off the incoming
water and opening the hot water tap. However, some
water may remain in the domestic coil. Drain by removing
the cold water connection XL3 on the water heater.
Emptying the vessel
Contact your installer if the vessel in EHZK 90 SPLIT, WWS
300 SPLIT, WWS 500 SPLIT needs emptying.
Maintenance of L8 SPLIT/L12 SPLIT
L8 SPLIT/L12 SPLIT is equipped with control and monitoring equipment, however some exterior maintenance is
still necessary.
Make regular checks throughout the year that the inlet
grille is not clogged by leaves, snow or anything else.
During the cold months of the year, check to make sure
that there isn't a build up of ice or frost under L8 SPLIT/L12
SPLIT. Strong wind combined with heavy snowfall can
block the intake and exhaust air grilles. Make sure that
there is no snow on the grilles.
Also check that the condensation water drain under L8
SPLIT/L12 SPLIT is not blocked.
If necessary the outer casing can be cleaned using a damp
cloth. Care must be exercised so that the heat pump is not
scratched when cleaning. Avoid spraying water into the
grilles or the sides so that water penetrates into L8
SPLIT/L12 SPLIT. Prevent L8 SPLIT/L12 SPLIT coming into
contact with alkaline cleaning agents.
!
WARNING!
Rotating fan in L8 SPLIT/L12 SPLIT.
Saving tips
Your SPLIT installation produces heat and hot water according to your needs. It also attempts to carry out all requirements with all available ”aids” from the control settings made.
The indoor temperature is naturally affected by the energy
consumption. Therefore, take care not to set a temperature
higher than necessary.
Other known factors that affect the energy consumption
are, for example, hot water consumption and the insulation level of the house, as well as the level of comfort you
require.
Also remember:
■ Open the thermostat valves completely (except in the
rooms that are to be kept cooler for various reasons, e.g.
bedrooms).
Thermostat valves in the radiators and floor loops can
negatively affect the energy consumption. They slow the
flow in the climate system, which the heat pump wants to
compensate with increased temperatures. It then works
harder and consumes more electrical energy.

EHZK 90 SPLIT
■ It is recommended that tank EHZK 90 SPLIT is installed
in a room with existing floor drainage, most suitably in
a utility room or boiler room.
■ Hang the tank with its back to an outside wall, ideally
in a room where noise does not matter. If this is not
possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem.
■ Secure the wall bracket (enclosed) to a wall of a suitable
material. Hook the tank onto the wall bracket. Install the
enclosed screw in the upper hole on the wall bracket to
hold the tank in place.
■ Route pipes so they are not fixed to an internal wall that
backs on to a bedroom or living room.
■ Ensure that there is approx. 500 mm free space in front
of, 600 mm to the right and 220 mm above the product
for pipework and any future service. Ensure that there
is sufficient space for the drain valve under the tank.
■ EHZK 90 SPLIT is provided with a manometer, a drainage
valve and a safety valve. The safety valve (FL2) should be
installed as close to the tank as possible. The drainage
valve should be positioned at the lowest point. The location of the manometer (BP5) is less sensitive.
Assembly
Outdoor module L8 SPLIT/L12 SPLIT
Position L8 SPLIT/L12 SPLIT outdoors secured to a firm
surface, preferably a concrete foundation on a ground
stand near walls, or on a wall mounting.
It must be positioned so that the lower edge of the evaporator is at the level of the average local snow depth,
however a minimum of 200 mm. L8 SPLIT/L12 SPLIT should
not be positioned next to noise-sensitive walls, for example, next to a bedroom. Also ensure that the location
does not inconvenience the neighbours. Care must be exercised so that the heat pump is not scratched during installation.
Large amounts of condensation water as well as melt
water from defrosting can be produced. Provide good
drainage at the installation area and make sure water
cannot run out onto paths or the like during periods that
ice can form.
The distance between L8 SPLIT/L12 SPLIT and the house
wall must be at least 150 mm. Ensure that there is at least
one metre of free space above L8 SPLIT/L12 SPLIT. L8
SPLIT/L12 SPLIT must not be placed so that recirculation of the outdoor air is possible. L8 SPLIT/L12 SPLIT
must not be placed in a windy location where it is exposed to direct strong winds. This reduces output and
impairs efficiency and also has a negative effect on the
defrosting function.

General information for the installer
Initial pressure and max height difference
Emptying the vessel
The pre-pressure of the pressure expansion vessel must
be dimensioned according to the maximum height (H)
between the vessel and the highest positioned radiator,
see figure. A pre-pressure of 0.5 bar (5 mvp) means a
maximum permitted height difference of 5 m.
The vessel in EHZK 90 SPLIT, WWS 300 SPLIT, WWS 500
SPLIT is emptied by opening the valve (QM1) and safety
valve (FL2).
NOTE
If the standard initial pressure in the pressure vessel is not
high enough it can be increased by filling via the valve in
the expansion vessel. The expansion vessel's standard initial
pressure must be entered in the check list on page 42.
When WWS 300 SPLIT/WWS 500 SPLIT is emptied
via the valve (QM1), some water will remain in the
coil and in HM 8-12 SPLIT.
This means that there is a risk of the heat exchanger,
pipes and valves freezing at low temperatures as well
as a hygienic risk for the coil in the hot water section.
Any change in the initial pressure affects the ability of the
expansion vessel to handle the expansion of the water.

Sound pressure levels
L8 SPLIT/L12 SPLIT is usually placed next to a house wall,
which gives a directed sound distribution that should be
considered. Accordingly, you should always attempt to
find a placement on the side that faces the least sound
sensitive neighbouring area.
LEK
The sound pressure levels are further affected by walls,
bricks, differences in ground level, etc and should therefore
only be seen as guide values.

Safety precautions
Safety precautions
Caution
Switch off the compressor before disconnecting the pipe from
the pump.
If the pipe is disconnected whilst the compressor is running and the
service valve is open, air is mixed into the process circuit. This causes
unusually high pressure in the process circuit, which can cause bursts
and personal injury.
The installation must be carried out by a qualified installer.
If you install the system yourself, serious problems may occur, for example water leaks, refrigerant leaks, electric shocks, fire and personal
injury, as a result of a system malfunction.
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.
Only use original accessories. The installation must be carried
out by a qualified installer.
If you install the system yourself, water leaks, electric shock and fire
can occur.
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 refrigerant density exceeds the limit, lack of oxygen can occur in the event
of any leak, which can cause serious accidents.
Do not perform any repairs yourself. Consult the dealer if the
system requires repair.
Incorrectly performed repairs can cause water leakage, refrigerant
leakage, electric shocks or fire.
Consult the dealer or an expert regarding removal of the heat
pump.
Incorrect installation can cause water leakage, refrigerant leaks,
electric shocks or fire.
Observe the measurement values, 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 refrigerant density exceeds the limit, lack of oxygen can occur in the event
of any leak, which can cause serious accidents.
Switch off the power supply in the event of a service or inspection.
If the power supply is not shut off, there is a risk of electric shocks
and damage due to the rotating fan.
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.
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.
Ventilate the working area well – refrigerant leakage may occur
during installation work.
If the refrigerant comes into contact with naked flames, poisonous
gas is created.
Cut the power before starting electrical work.
Failure to cut the power can cause electric shocks, damage and incorrect function of the equipment.
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.
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.
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.
Use main switch with sufficient breaking capacity.
If the switch does not have sufficient breaking capacity, malfunctions
and fire can occur.
Ensure that no air enters the process circuit when the heat pump
is installed or removed.
If air enters the process circuit, the pressure becomes too high, which
can cause bursts and personal injury.
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.
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.
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.
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.
Do not install the indoor 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 nitrous
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.
Arrange the wiring in the control box so that it cannot be pushed
up further into the box by mistake. Install the service panel's
cover correctly.
Incorrect installation can result in overheating and fire.
Check, after completed installation, that no refrigerant 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.
Do not use the indoor section where water splashes may occur,
for example in laundries.
The indoor section is not waterproof and electric shocks and fire can
therefore occur.
Do not use the indoor section for storing food, cooling precision
instruments, freeze-conservation of animals, plants or art.
This can damage the items.
For R410A use the stated pipe type and cap nuts and for R410A
use the stated tool.
Using existing parts (for R22) can cause breakdowns and serious accidents due to process circuit bursts.
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 air
conditioning unit and cause malfunctions and breakdowns. The air
conditioning unit can also affect medical equipment and telecommunications equipment, so that it functions incorrectly or not at all.
Tighten the cap nut as stated using a torque wrench.
Tighten to the correct torque. Overtightening of the cap nut can lead
to breaks and refrigerant leaks.
Connect the cooling circuit pipe and complete the pipe installation before running the compressor.
If the compressor is run when the service valve is not open and the
pipe is not connected, the system may burst causing personal injury,
due to abnormally high pressure in the system.
98
Do not install the outdoor unit in the locations stated below.
- Locations where leakage of combustible gas can occur.
- Locations where carbon fibre, metal powder or other powder that
can enter the air.
SPLIT
Miscellaneous
Safety precautions
If the unit weights more than 20 kg, it must be carried by two people.
Do not carry by the plastic strap, always use the carry handle when
carrying the unit by hand. Use gloves to minimize the risk of cuts from
the aluminium flanges.
- Locations where substances that can affect the air conditioning unit,
for example, sulphide gas, chlorine, acid or alkaline substances can
occur.
- Locations with direct exposure to oil mist or steam.
- Vehicles and ships.
- Locations where machines that generate high frequency harmonics
are used.
- Locations where cosmetic or special sprays are often used.
- Locations that can be subjected to direct salty atmospheres. In this
case, the outdoor unit must be protected against direct intakes of
salty air.
- Locations where large amounts of snow occur.
- Locations where the system is exposed to chimney smoke.
Dispose of any packaging material correctly.
Any remaining packaging material can cause personal injury as it
contains 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.
If the bottom frame of the outdoor section is corroded, or in any
other way damaged, due to long periods of operation, it must
not be used.
Using an old and damaged frame can cause the unit to fall and cause
personal injury.
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.
If soldering near the unit, ensure that solder residue does not
damage the drip tray.
If solder residue enters the unit during soldering, small holes can appear in the tray resulting in water leakage. To prevent damage, keep
the indoor unit in its packing or cover it.
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.
Do not allow the drainage pipe to exit into channels where
poisonous gases, containing sulphides for example, can occur.
If the pipe exits into such a channel, any poisonous gases will flow
into the room and seriously affect the user's health and safety.
Especially for units intended for R410A
Insulate the cooler unit's connection pipes so that the ambient
air moisture does not condense on them.
Insufficient insulation can cause condensation, which can lead to
moisture damage on the roof, floor, furniture and valuable personal
property.
- The service valve's filling connection and control output on the indoor unit in the system for R410A are different sizes, to prevent the
system being filled with the incorrect refrigerant by mistake. The
machined dimension on the refrigerant pipe’s collared part as well
as the cap nut’s parallel side dimension has been changed to increase
the system's overpressure resistance.
- Do not use other refrigerants than R410A. R410A means that the
pressure is about 1.6 times as high as conventional refrigerants.
Do not install the outdoor unit in a location where insects and
small animals can inhabit.
Insects and small animals can enter the electronic parts and cause
damage and fire. Instruct the user to keep the surrounding equipment
clean.
- Therefore, installers and service technicians must ensure that only
tools approved for working with R410A are used.
- Do not use charging bottles. These types of bottles change the
composition of the refrigerant, which makes the performance of the
system worse.
Take care when carrying the unit by hand.
- When filling refrigerant, the refrigerant must always leave the bottle
in liquid form.
