NSTALLATION OF THE INDOOR UNIT

Selecting an installation location

Make sure to provide for adequate measures in
NOTE
order to prevent that the indoor unit should be
used as a shelter by small animals.
Small animals making contact with electrical parts
can cause malfunctions, smoke or fire. Please
instruct the customer to keep the area around the
unit clean.
The unit is to be placed in an indoor location that meets the following
requirements:
The installation location is frost-free.
The space around the unit is adequate for servicing. (See
figure 2).
The space around the unit allows for sufficient air circulation.
There is a provision for pressure relief valve blow-off.
There is no danger of fire due to leakage of inflammable gas.
The equipment is not intended for use in a potentially explosive
atmosphere.
All piping lengths and distances have been taken into
consideration.
Requirement
Maximum allowable refrigerant piping length between
outdoor unit and indoor unit
Minimum required refrigerant piping length between
outdoor unit and indoor unit
Maximum allowable height difference between
outdoor unit and indoor unit
Maximum allowable distance between the domestic
hot water tank and the indoor unit (only for
installations with domestic hot water tank).
NOTE If the installation is equipped with a domestic hot water
tank (optional), please refer to the domestic hot water
tank installation manual.
Do not install the unit in places often used as workplace.
In case of construction works (e.g. grinding works) where a lot of
dust is created, the unit must be covered.
Do not install the unit in places with high humidity (e.g.
bathroom) (maximum humidity (RH) = 85%).
If the sound is measured under actual installation conditions, the
measured value will be higher than the sound pressure level
mentioned in the "Unit specifications" on page 34 due to
environmental noise and sound reflections. Choose the
installation location carefully and do not install in a sound
sensitive environment (e.g. living room, bedroom, ...).
Take care that in the event of a water leak, water can not cause
any damage to the installation space and surroundings.
The foundation must be strong enough to support the weight of
the unit (or unit and optional domestic hot water tank completely
filled with water in case the optional domestic hot water tank is
mounted on top of the unit).
The floor is flat to prevent vibrations and noise generation and to
have sufficient stability especially when the optional domestic
hot water tank is mounted on top of the unit.
Do not place any objects or equipment on top of the unit (top
plate).
Do not climb, sit or stand on top of the unit.
Be sure that sufficient precautions are taken, in accordance with
relevant local and national regulations, in case of refrigerant
leakage.

Inspecting and handling the unit

At delivery, the unit must be checked and any damage must be
Value
reported immediately to the carrier claims agent.
Bring the unit as close as possible to its final installation position
50 m
in its original package in order to prevent damage during
3 m transport.
Unpack the indoor unit completely according to the instructions
30 m
mentioned on the unpacking instructions sheet.
Check if all indoor unit accessories (see "Accessories" on
10 m
page 6) are enclosed.

Installing the indoor unit

For installation of the outdoor unit, refer to the
NOTE
installation manual of the outdoor unit.
For connecting piping and electrical cables, knockout holes are
provided at the back of the unit.
To punch a knockout hole, hit on it with a hammer.
When passing electrical wiring or piping through the
knockout holes, remove any burrs from the knockout holes.

depending on your installation location.
Refrigerant piping and water piping must go
through different knockout holes.
The electrical wiring must always enter the unit
through the knockout holes at the left side of the
unit (see figure 4).
