4. SELECTING INSTALLATION SITE
(1) Select an installation site where the following conditions are
satisfied and that meets with your customer’s approval.
• Places which are well-ventilated.
• Places where the unit does not bother next-door neighbors.
• A locations where small animals will not make nests in the unit.
• Safe places which can withstand the unit’s weight and vibration and
where the unit can be installed level.
• Locations not exposed to rain.
• A locations where there is enough space to install the unit.
• Places where the indoor and outdoor unit’s piping and wiring
lengths come within the allowable ranges.
• A location where there is no risk of flammable gas leaking.
(2) If the unit is installed in a location where it might be exposed to
strong wind, install as per figure 3.
• 16.4ft./sec or more strong wind blown against the outdoor unit’s air
outlet causes the outdoor unit to deteriorate in air capacity and
suck in the air blown out of its air outlet (short circuit), and the fol-
lowing effects may result.
• Drop in performance.
• Increased frost formation in heating mode.
• Shutting down due to increase in pressure.
• If very strong wind blows continuously on the side of the outdoor
unit with the outlet vent, the fan may turn in reverse at high speed
and break, so install as per figure 3.
(Refer to figure 3)
1. Turn the air outlet side toward the building’s wall, fence or
windbreak screen.
2. Air inlet grille
3. Ensuring there is enough space for installing the unit.
4. Set the outlet side at a right angle to the direction of the
wind.
5. Strong wind
6. Blown air
(3) In installing the unit in a place frequently exposed to snow, pay
special attention to the following:
• Elevate the foundation as high as possible.
• Attach the snow hood (field supply).
• Remove the rear inlet grille to prevent snow from accumulating on
the rear fins.
(4) The outdoor unit may short circuit depending on its environment, so
use the louvers (field supply).
(5) The refrigerant gas (R410A) is a safe, non-toxic and non-flammable
gas, but if it leaks into the room, the concentration may exceed tol-
erance levels, especially in small rooms, so steps need to be taken
to prevent refrigerant leakage. See the equipment design reference
for details.
(6) Inverter-type air conditioners sometimes cause static in other elec-
trical appliances.
When selecting an installation location, make sure the air condi-
tioner and all wiring are sufficiently far away from radios, computers,
stereos, and other appliances, as shown in figure 4.
Particularly for locations with weak reception, ensure there is a dis-
tance of at least 9.8ft. for indoor remote controllers, place power
supply wiring and transmission wiring in conduits, and ground the
conduits. Use shielded wire for transmission wiring.
(Refer to figure 4)
1. Indoor unit
2. Branch switch (ground fault circuit interrupter)
3. Remote controller
4. Personal computer or radio
(7) Space needed for installation
<Precautions when installing units in series>
• The direction for interunit piping is either forward or down when
installing units in series, as shown in the figure.
• If the piping is brought out from the back, the outdoor unit will
require at least 10in. from its right side.
(All figures represent millimeters.)
(7)-1 IN CASE OBSTACLES EXIST ONLY IN FRONT OF THE AIR
INLET
When nothing is obstructing the top
1.
Installation of single unit
• In case obstacles exist only in front of the air inlet
(Refer to figure 5-[1])
• In case obstacles exist in front of the air inlet and on both sides of
the unit (Refer to figure 5-[2])
2.
In case of installing multiple units (2 units or more) in lateral connec-
tion per row
• In case obstacles exist in front of the air inlet and on both sides of
the unit (Refer to figure 5-[3])
When something is obstructing the top
1.
Installation of single unit
• In case obstacles exist only in front of the air inlet
(Refer to figure 6-[1])
• In case obstacles exist in front of the air inlet and on both sides of
the unit (Refer to figure 6-[2])
2.
In case of installing multiple units (2 units or more) in lateral connec-
tion per row
• In case obstacles exist in front of the air inlet and on both sides of
the unit (Refer to figure 6-[3])
(7)-2 IN CASE OBSTACLES EXIST IN FRONT OF THE OUTLET
SIDE
When nothing is obstructing the top
1.
Installation of single unit (Refer to figure 7-[1])
2.
In case of installing multiple units (2 units or more) in lateral connec-
tion per row (Refer to figure 7-[2])
When something is obstructing the top
1.
Installation of single unit (Refer to figure 7-[3])
2.
In case of installing multiple units (2 units or more) in lateral connec-
tion per row (Refer to figure 7-[4])
(7)-3 IN CASE OBSTACLES EXIST IN FRONT OF BOTH THE AIR
INLET AND OUTLET SIDES
Pattern 1: Where obstacle in front of the air outlet is higher than the
unit.
(There is no height limit for obstructions on the intake side.)
When nothing is obstructing the top
1.
Installation of single unit (Refer to figure 8-[1])
2.
In case of installing multiple units (2 units or more) in lateral connec-
tion per row (Refer to figure 8-[2])
When something is obstructing the top
1.
Installation of single unit (Refer to figure 8-[3])
