Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind will
disturb the operation of the unit. If necessary, use a windscreen
to block the wind.
9
Do not install or operate the unit on locations where air contains
high levels of salt, like e.g. in the vicinity of oceans.
10
During installation, avoid the possibility that children can mount
on the unit or place any object on the unit.
Falling or tumble may result in injury.
11
The equipment is not intended for use in a potentially explosive
atmosphere.

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 in advance the path along which the unit is to be
brought in.
3
Bring the unit as close as possible to its final installation position
in its original package to prevent damage during transport.
(See
figure 4)
4
Lift the unit preferably with a crane and 2 belts of at least 8 m
long.
(See figure 4)
Always use protectors to prevent belt damage and pay attention
to the position of the unit's centre of gravity.
5
If a forklift is to be used, preferably
transport the unit with pallet first,
then pass the forklift arms through
the large rectangular openings on
the bottom of the unit.
5.1
From the moment you use a forklift to
move the unit to its final position, lift
the unit under the pallet.
5.2
Once at final position, unpack the unit and pass the forklift arms
through the large rectangular openings on the bottom of the unit.

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
figure 5
.
■
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...
(See
figure 3)
.
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.

NOTE
Use a belt sling of

bears the weight of the unit.
NOTE
Use filler cloth on the forklift arms to prevent
damaging the unit. If the paint on the bottom
frame peels off, the anti corrosion effect may
decrease.
