NSPECTING
AND
HANDLING
THE
UNIT
At delivery, the package should be checked and any damage should
be reported immediately to the carrier claims agent.
When handling the unit, take into account the following:
1
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2
Choose on beforehand the path along which the unit is to be
brought in.
3
Lift the unit preferably with a crane and 2 belts of at least 8 m
long.
4
When lifting the unit with a crane, always use protectors to
prevent belt damage and pay attention to the position of the
unit's centre of gravity.
5
Bring the unit as close to its final installation position in its
original package to prevent damage during transport.

NPACKING
AND
PLACING
THE
UNIT
■
Remove the four screws fixing the unit to the pallet.
■
Make sure the unit is installed level on a sufficiently strong base
to prevent vibration and noise.
■
Fasten the unit in place using four anchor bolts M12.
■
Make sure the base under the unit is more than 765 mm.
■
The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in
.
■
Support the unit with a foundation of 66 mm width or more. (The
support leg of the unit is 66 mm width).
■
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...
In extreme circumstances you should keep distances of
3 m or more and use conduit tubes for power and
transmission lines.
■
In heavy snowfall areas, select an installation site
where snow will not affect operation of the unit.
■
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.
■
Do not install in the following locations.
•
Locations where acidic or alkaline vapour is
present.
•
Locations where sulfurous acids and other corrosive
gases may be present in the atmosphere.
Copper piping and soldered joints may corrode,
causing refrigerant to leak.
•
Locations where there is mist of mineral oil, oil spray or
vapor for example a kitchen.
Plastic parts may deteriorate, and cause them to
fall out or water to leak.
•
Locations where the air contains high levels of salt
such as that near the ocean.
•
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.
•
Locations where equipment that produces electro-
magnetic waves is found.
The electromagnetic waves may cause the control
system to malfunction, preventing normal operation.
•
Locations where voltage fluctuates a lot, such as
that in factories.
•
In vehicles or vessels.
■
During installation, take strong winds, typhoons or
earthquakes into account.
Improper installation may result in fall over of the unit.

Do not use stands to support the corners.
■
Prepare a water drainage channel around the
foundation to drain waste water from around the unit.
■
If the unit is to be installed on a roof, check the
strength of the roof and its drainage facilities first.
■
If the unit is to be installed on a frame, install the
waterproofing board within a distance of 150 mm
under the unit in order to prevent infiltration of water
coming from under the unit.
■
When installed in a corrosive
environment, use a nut with a
resin clip plate (1) to protect the
nut tightening part from rust.
