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.
Pay attention to the measurement values before working on
the cooling system, especially when servicing in small rooms,
so that the limit for the refrigerant’s concentration is not ex-
ceeded.
Consult an expert to interpret the measurement values. If the refri-
gerant concentration exceeds the limit, there may be a shortage
of oxygen in the event of any leak, which can cause serious injury.
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.
Switch off the compressor before opening/breaching the refri-
gerant 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 inspec-
tion.
AMS 10Chapter 1 | Important information4
1 Important information

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.
Use main switch with sufficient breaking capacity.
If the switch does not have sufficient breaking capacity, malfunc-
tions 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 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.
Do not use the unit where water splashes may occur, for ex-
ample in laundries.
The indoor section is not waterproof and electric shocks and fire
can therefore occur.
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.
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.
- Locations where substances that can affect the 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 harmon-
ics 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.
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.
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 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.
Insulate the 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.
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 equip-
ment clean.
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
- Do not use other refrigerants than R410A. R410A means that the
pressure is about 1.6 times as high as conventional refrigerants.
- 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.

7Chapter 1 | Important informationAMS 10

Transport and storage
AMS 10 must be transported and stored vertically.
NOTE
Ensure that the heat pump cannot fall over
during transport.
Assembly
■Place AMS 10 outdoors on a solid level base that can
take the weight, preferably a concrete foundation. If
concrete slabs are used they must rest on asphalt or
shingle.
■The concrete foundation or slabs 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 300 mm. See our stands and brackets on page 36.
■AMS 10 should not be positioned next to noise sensit-
ive walls, for example, next to a bedroom.
■Also ensure that the placement does not inconveni-
ence the neighbours.
■AMS 10 must not be placed so that recirculation of the
outdoor air can occur. This causes lower output and
impaired efficiency.
■The evaporator should be sheltered from direct wind,
which negatively affects the defrosting function. Place
AMS 10 protected from wind against the evaporator.
■Large amounts of condensation water, as well as melt
water from defrosting, can be produced. Condensation
water must be led off to a drain or similar (see page9).
■Care must be exercised so that the heat pump is not
scratched during installation.
LEK

300 mm
Do not place AMS 10 directly on the lawn or other non
solid surface.
If there is a risk of snow slip from roof, a protective roof
or cover must be erected to protect the heat pump, pipes
and wiring.
AMS 10Chapter 2 | Delivery and handling8
2 Delivery and handling

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 AMS 10 to the set up location.
NOTE
The centre of gravity is offset to one side (see
print on the packaging).
If AMS 10 needs to be transported across soft ground,
such as a lawn, we recommend that a crane truck is used
that can lift the unit to the installation location. When
AMS 10 is lifted with a crane, the packaging must be
undamaged and the load distributed with a boom, see
the illustration above.
If a crane cannot be used AMS 10 can be transported
using an extended sack truck. AMS 10 must be used on
the side marked "heavy side" and two people are re-
quired to get the AMS 10 up.
Lift from the pallet to final positioning
Before lifting remove the packaging and the securing
strap to the pallet.
Place lifting straps around each machine foot. Lifting
from the pallet to the base requires four persons, one
for each lifting strap.
It is not permitted to lift anything other than the machine
feet.
Scrapping
When scrapping, the product is removed in reverse order.
Lift by the bottom panel instead of a pallet!
Condensation run off
Condensation runs out on to the ground below AMS 10.
To avoid damage to the house and heat pump, the
condensation must be gathered and drained away.
NOTE
It is important to the heat pump function that
condensation water is led away and that the
drain for the condensation water run off is not
positioned so that it can cause damage to the
house.
NOTE
To ensure this function, the accessory KVR 10
should be used. (Not included)
NOTE
The electrical installation and wiring must be
carried out under the supervision of an author-
ised electrician.
NOTE
Self regulating heating cables must not be
connected.
■The condensation water (up to 50 litres / 24 hrs) must
be routed away by a pipe to an appropriate drain, it is
recommended that the shortest outdoor length pos-
sible is used.
■The section of the pipe that can be affected by frost
must be heated by the heating cable to prevent
freezing.
■Route the pipe downward from AMS 10.
■The outlet of the condensation water pipe must be at
a depth that is frost free or alternatively indoors (with
reservation for local ordinances and regulations).
■Use a water trap for installations where air circulation
may occur in the condensation water pipe.
■The insulation must be tight against the bottom of the
condensation water trough.
Drain pan heater, control
The drain pan heater is supplied with power when one
of the following conditions is met:
1. The compressor has been in operation for at least
30 minutes after last start.
2. The ambient temperature is lower than 1 °C.
