3
There is no danger of fire due to leakage of inflammable gas.
4
Ensure that water cannot cause any damage to the location in
case it drips out the unit (e.g. in case of a blocked drain pipe).
5
The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length. (Refer to
"6.3. Example of connection" on page 7
)
6
Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
anyone.
7
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.
8
Do not install or operate the unit on locations where air contains
high levels of salt, like e.g. in the vicinity of oceans. (Refer for
further information to the engineering databook).

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
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 extended more than
765 mm behind the unit.
■
The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in
figure 4
.
■
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 2)
.
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 R-410A 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 the chapter
"10. Caution for
refrigerant leaks" on page 20
.
■
Do not install in the following locations.
•
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 equipment that produces electro-
magnetic 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.

Do not use stands to support the corners.
(See figure 6)
■
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.
