function and the unit may be damaged.
• Do not use the R22 manifold gauge.
- Always use the high-pressure R410A manifold gauge for a stable charging.
• Do not use the R22 pipes and installation materials for the R410A installation. (do not mix
them up)
- Mixing the R22 refrigerant oil with the R410A oil will cause a hydrolysis, and may lead to fire
or failure of the air conditioner.
• Install the air conditioner onto a sturdy place where it can sustain the weight.
- Improper location may cause the air conditioner to fall and get damaged.
• Do not reconstruct to change the settings of the protection devices.
- If the protection device is shorted and modified, and operated forcibly, fire or explosion may
result.
• Always use a vacuum pump or Inert (nitrogen)gas when doing leakage test or air purge.
- Use of oxygen, compressed air and flammable gases may cause fire and explosion.
There is risk of death, property damage, or explosion.
• Check what kind of fuel gas is used.
- Using an incorrect type of gas may cause the operation failure of the engine and the mal-
function of the engine combustion, and result a carbon monoxide poisoning and the break-
down of the engine.
• Do not combine the exhaust drain hose of the indoor unit and the outdoor unit.
- Combining the exhaust drain hose will make the exhaust flow backward in and increase the
risk of carbon monoxide poisoning.
• Install the outdoor unit properly to prevent a reversed flow of the exhaust gas.
- Exhaust gas flowing backward into a building may cause carbon dioxide poisoning.
• If the air conditioner is installed in a small room, measures must be taken to prevent to refrig-
erant concentration from exceeding the safety limit when the refrigerant leaks.
- If the refrigerant leaks and exceeds the safety limit, hazards due to lack of oxygen in the
room could result.
• Ventilate before operating air conditioner when refrigerant gas leaks.
- If the refrigerant contacts inflammables such as welding flame, hazardous gas may result.
• The power of indoor and outdoor units must be separated when installing.

14 SELECTION OF INSTALLATION SITE
ENGLISH
SELECTION OF INSTALLATION SITE
Considerations when selecting an outdoor unit installation site
• You need to select adequate installation location considering the following conditions, and
make sure to acquire the consent of the user.
• A place where exhaust gas does not flow back into a building or does not remain
• Beware that exhaust gas and air flowing out of the outdoor unit fan may cause harm to the ani-
mals and plants.
• A place without direct thermal radiation from other heat sources
• A place where the noise from the outdoor unit will not disturb the neighbors
• A place not exposed to a strong wind
• Place that can sufficiently endure the weight and vibration of the outdoor unit and where even
installation is possible.
• A place where the drain flows out of the unit well
• A place with space for air passage and service work. Avoid the unit installation in a place where
generation, inflow, stagnation, and leakage of exhaust gas is expected in order to prevent fire.
• Avoid the unit installation in a place where corrosive gas such as acidic and alkaline gas is exist-
ed.
• In order to operate the unit more stable below the outdoor temperature 10°C, avoid a place
exposed to snow or rain directly. Otherwise, install a duct for air suction/discharge.
• Do not use the unit under any special environment where oil, steam and sulfuric gas exist.
• When the outdoor temperature is below -5°C, installing the outdoor unit for air conditioning is
restricted.
• It is recommended to fence round the outdoor unit in order to prevent any person or animal
from accessing the outdoor unit.
• If necessary, install a warning signs indicating a danger.
• If installation site is an area of high humidity in winter (seaside, lakeside), make sure to install
the outdoor unit in a place where it has good ventilation with a plenty of sunshine (e.g: rooftop).
• If it is installed at a place with a lot of snowfall, install with the frame and base height higher
than the most extreme snowfall amount standard, and mount the snowfall hood (separately
sold).
• The noise from the unit may cause disturb the other devices. Electrical wiring should be done
at least more than 5 m from computer, radio, TV, phone, other cables, antenna, and so on.
• Do not install the inlet/outlet of the outdoor unit facing a seasonal wind.
• If the outdoor unit for winter is installed in such places as below,
it may delay the preheat time of the indoor unit and
cause a poor heating operation.

- If the outdoor unit should be installed facing
the sea wind, build a windbreak around the
unit to protect it from the wind.
• Sufficient measures are required for a nor-
mal operation in the areas where a heavy
snow and harsh weather conditions are
expected.
• Install the unit considering seasonal wind or
snow in winter for other areas as well.
• Attach a hood to the inlet/outlet to prevent
snow or rain from entering the unit directly
when the unit is operated at the outdoor
temperature below 10.
• Install the outdoor unit not to come in con-
tact with snow directly. If snow piles up and
freezes on the inlet, the system may mal-
function.
• Make sure to clear away the snow before
operating when snow piles up more than
100mm on top of the outdoor unit.
• Install the outdoor unit where it can be pro-
tected from heavy snow.
• Do not install the outdoor unit on weak
ground such as a dilapidated part of building
or an area prone to snow accumulation.
• Do not install the outdoor unit under any
eaves or any area where an icicle or snow
may fall, because this may cause damage.

decrepit part of the building or with a lot of
snow accumulation.
The materials of windbreak, such as concrete,
should be strong enough to protect the out-
door unit from the sea wind. The height and
width should be more than 150% of the size
of outdoor unit.
The distance between the windbreak and the
outdoor unit should be more than 700mm for
easy air flow.
• Place with fluent water draining
- Install at a place with fluent water draining
to prevent damage from localized heavy
rain and avoid frequent flooded area.
Coastal wind
Wall
CAUTION
• Do not install the air conditioner where it
could be exposed to sea wind directly.
• If the outdoor unit is installed close to
the seaside, it needs additional anticor-
rosion treatment on the heat exchanger.
!
* Periodic (more than once a year) clean-
ing of the dust or salt particles stuck on
the heat exchanger by using water.
* Selecting the site (outdoor unit)
- Install the outdoor unit where the sea wind
can be avoided.

• Lift the unit by using a crane rope to the carrying hole in the bottom base of the outdoor unit.
• Avoid scratches or distortion on the external panel with protective support when suspending.
• There is a risk of dropping when the unit is hoisted by a forklift. Do not hoist the unit forcibly
when it is off balance.
• Make sure to use a rope long enough so that the distance between the top of the outdoor unit
and the hook can be more than 1 m.
• Make sure to use the proper ropes strong enough to support the weight of the outdoor unit.
• The use of improper ropes may result in dropping.
• Always transport the outdoor unit upright (vertically). It is dangerous to transport the outdoor
unit flat (horizontally) and it may also cause a malfunction.
• When carrying, place the forks of the forklift into the carrying hole for forklift.

CAUTION
Pay special attention when carrying the unit.
• The PP bands (PET bands) are used for packing. It is dangerous to use the PP bands to
transport the unit.
• Do not touch the heat exchanger fins with your bare hands. You can get a cut in your
hands.
• Tear apart and throw away plastic packaging bags so that children will not play with them.
Children playing with plastic bags face the danger of suffocation.
• When carrying the outdoor unit, be sure to support it at four points. Carrying it with 3-point
support may make the outdoor unit unstable and fall.
• Hoist the unit making sure it is being lifted at its center of gravity.

Foundation Installation
CAUTION
• Make sure to level a concrete foundation and to have good drainage.
• When installing the outdoor unit, always use a dedicated anchor bolts.
• Make sure to use anti-vibration materials (cushion pad) so that the bottom surface of the
outdoor unit can get the evenly distributed weight.
• When installing the outdoor unit at the rooftop of a building, use an anti-vibration stand.
• For ground-level installation, install an anti-vibration stand if the area is sensitive to vibra-
tion or noise.
• Insert the rubber pad of over 10 t between the concrete foundation and the anti-vibration
pad.

• The nuts #3 and #4 are fixed onto the side of the anti-vibration stand.
• There is an appropriate distance (10 mm) from the bolt #1 and nut #2 to the ODU, as seen in
the picture on the left.
• The bolt should not be touching a concrete floor.
• Non-compliance with the above may cause the outdoor unit to vibrate.
• When using an anti-vibration stand, keep the outdoor unit at least more than 1,500mm from the
first anchor point of the refrigerant pipe.

CAUTION
• Be sure to remove the pallet (wooden support) of the bottom of the outdoor unit bas pan
before using an anchor bolt. It can make the foundation of the outdoor unit unstable, and
may cause freezing of the heat exchanger resulting in abnormal operations.
• Be sure to remove the pallet (wooden support) of the bottom of the outdoor unit before
welding. Not removing the pallet causes hazard of fire during welding.
!
• Install where it can sufficiently support the weight of the outdoor unit. If the support
strength is not enough, the outdoor unit may drop and hurt people.
• Install where the outdoor unit may not fall in strong wind or earthquake. If there is a fault
in the supporting conditions, the outdoor unit may fall and hurt people.
• Please take extra cautions on the supporting strength of the ground, water outlet treat-
ment (treatment of the water flowing out of the outdoor unit in operation), and the pas-
sages of the pipe and wiring, when making the ground support.

CAUTION
• Extend the drain pipes to a gutter(water outlet) for drainage. A direct drainage to the sur-
face of waterproof sheets or concrete causes contamination or damage.
• Take preventive measures to protect the drain pipes from freezing in winter.
!
• When connecting the rubber drain hose of the outdoor unit to the pipe for drainage, make
sure to lay pipes exposed(released) to the air. If the exhaust gas flows backward inside a
building, it causes a carbon dioxide poisoning.
• Do not use the indoor unit drain pipes mixed with the outdoor unit drain pipes.
If the exhaust gas flows backward inside a building through the indoor unit drain pipes, it
causes a carbon dioxide poisoning.
WARNING
!
• The drain piping work should be done with a falling gradient of more than 1/50 for better
drainage. Do not add any shaft tubes to the drain pipes. Do not add any traps to the drain pipes.
If the multiple indoor units share the same drain pipe, keep the each rubber hose open to the
air. Otherwise, the exhaust gas from the outdoor unit in operation could flow backward into the
indoor unit (not in operation) and cause an engine malfunction.
• Use the corrosion-free hardened Polyvinyl Chloride (PVC) or stainless tubes for the drain piping.
