INSTALLATION

 

LOCATION

General precautions on installation location

Select an installation site that meets the following requirements:

The foundation must be strong enough to support the weight of
the unit. The floor is flat to prevent vibrations and noise
generation and to have sufficient stability.

The space around the unit is adequate for maintenance and
servicing (refer to 

"7.2. Service space" on page 9

).

The space around the unit allows for sufficient air circulation.

There is no danger of fire due to leakage of inflammable gas.

The equipment is not intended for use in a potentially explosive
atmosphere.

Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location
is selected according the applicable legislation.

All piping lengths and distances have been taken into
consideration (refer to 

"9.4. 

System piping limitations" on

page 12

).

Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.

When installing the unit in a small room, take measures in order
to keep the refrigerant concentration from exceeding allowable
safety limits in the event of a refrigerant leak.

In places with weak reception, keep distances of
3 m or more to avoid electromagnetic disturbance
of other equipment and use conduit tubes for
power and transmission lines.

The refrigerant R410A itself is nontoxic,
nonflammable and is safe. If the refrigerant should
leak however, its concentration may exceed the
allowable limit depending on room size. Due to
this, it could be necessary to take measures
against leakage. Refer to 

"17. Caution  for

refrigerant leaks" on page 29

.

Do not install in the following locations.

Locations where sulphurous acids and other
corrosive gases may be present in the
atmosphere.
Copper piping and soldered joints may
corrode, causing refrigerant to leak.

Locations where a mineral oil mist, spray or
vapour may be present in the atmosphere.
Plastic parts may deteriorate and fall off or
cause water leakage.

Locations where equipment that produces
electromagnetic waves is found.
The electromagnetic waves may cause the
control system to malfunction, preventing
normal operation.

Locations where flammable gases may leak,
where thinner, gasoline and other volatile
substances are handled, or where carbon
dust and other incendiary substances are
found in the atmosphere.
Leaked gas may accumulate around the unit,
causing an explosion.

When installing, take strong winds, typhoons or
earthquakes into account.
Improper installation may result in the unit turning
over.

WARNING

Be sure to provide for adequate measures in order to
prevent that the unit is 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 and clear.

This is a class A product. In a domestic environment this
product may cause radio interference in which case the
user may be required to take adequate measures.

CAUTION

Appliance not accessible to the general public, install it in a
secured area, protected from easy access.

This unit, both indoor and outdoor, is suitable for
installation in a commercial and light industrial
environment.

Excessive refrigerant concentrations in a closed room
can lead to oxygen deficiency.

NOTE

The equipment described in this manual may
cause electronic noise generated from radio-
frequency energy. The equipment complies to
specifications that are designed to provide
reasonable protection against such interference.
However, there is no guarantee that interference
will not occur in a particular installation.
It is therefore recommended to install the
equipment and electric wires keeping proper
distances away from stereo equipment, personal
computers, etc....
