to the Engineering Data Book.

ELECTION OF LOCATION
This unit, both indoor and outdoor, is suitable for installation in a
commercial and light industrial environment. If installed as a
household appliance it could cause electromagnetic interference.
The inverter units should be installed in a location that meets the
following requirements:
1. The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
2. The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available. (refer to
figure 1 and choose one of both possibilities)
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. (see "Example of
connection")
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.
Caution
1. An inverter air conditioner may cause electronic noise
generated from AM broadcasting. Examine where to install the
main air conditioner and electric wires, keeping proper distances
away from stereo equipment, personal computers, etc. (refer to
figure 2).

5 cool/heat selector
6 indoor unit
If the electric wave of AM broadcasting is particularly weak,
keep distances of 3m or more and use conduit tubes for power
and transmission lines.
2. In heavy snowfall areas, select an installation site where snow
will not affect operation of the unit.
3. The refrigerant R407C 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 "Caution for refrigerant leaks".

NSPECTING AND HANDLING THE UNIT
The units are packed in a wooden crate and attached on a wooden
pallet.
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.
3
2. Lift the unit preferably with a crane
and 2 belts(1) of at least 8m long.
3. When lifting the unit with a crane,
always use protectors(2) to
prevent belt damage and pay
attention to the position of the
unit's centre of gravity.
4. Bring the unit as close to its final
installation position in its original
package to prevent damage
during transport.
U
NPACKING AND PLACING THE UNIT
1. Remove the wooden crate from the unit.
2. Remove the four screws fixing the unit to the pallet.
3. The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in figure 4.
Note Maximum height of the foundation is 150mm.
4. Lift the unit from the pallet and place it on its installation position.
5. Fasten the unit in place using four anchor bolts M12.
6. Remove the upper and lower service plate.
7. When closing the service panels take care that the tightening
torque does not exceed 4.1 Nm.
8. Remove the yellow shipping
stays from the compressor
support as shown in the figure
(2 stays per single
compressor).
Tighten the installation bolts
firmly again afterwards.
Caution
1. Prepare a water drainage channel around the foundation to
drain waste water from around the unit.
2. If the unit is to be installed on a roof, check the strength of the
roof and its drainage facilities first.
3. If the unit is to be installed on a frame, install the waterproofing
board within a distance of 150mm under the unit in order to
prevent infiltration of water coming from under the unit.
R
EFRIGERANT PIPING
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and national
regulations.
Note
- Use R407C only when adding refrigerant.
- Installation tools:
Make sure to use installation tools (gauge manifold charge
hose, etc.) that are exclusively used for R407C installations to
withstand the pressure and to prevent foreign materials (e.g.
mineral oils such as SUNISO and moisture) from mixing into the
system.
Vacuum pump (use a 2-stage vacuum pump with a non-return
valve):
1. Make sure the pump oil does not flow oppositely into the system
while the pump is not working.
2. Use a vacuum pump which can evacuate to -100.7 kPa (5Torr,
-755mmHg).
