2.1. Choosing the outdoor unit installation location
○
R290 is heavier than air—as well as other refrigerants—so tends to accumulate
at the base (in the vicinity of the floor). If R290 accumulates around base, it may
reach a flammable concentration in case room is small. To avoid ignition, main-
taining a safe work environment is required by ensuring appropriate ventilation. If
a refrigerant leak is confirmed in a room or an area where there is insufficient ven-
tilation, refrain from using of flames until the work environment can be improved
by ensuring appropriate ventilation.
• Avoid locations exposed to direct sunlight or other sources of heat.
• Select a location from which noise emitted by the unit will not inconvenience
neighbors.
• Select a location permitting easy wiring and pipe access to the power source and
indoor unit.
• Avoid locations where combustible gases may leak, be produced, flow, or ac-
cumulate.
• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation loca-
tion or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the airflow
and a malfunction may result.
• Avoid locations exposed to oil, steam, or sulfuric gas.
• Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or fingers may be pinched.
• Refrigerant pipes connection shall be accessible for maintenance purposes.
○
Install outdoor units in a place where at least one of the four sides is open, and in
a sufficiently large space without depressions. (Fig. 2-1)
• Define a protective zone close around the unit according to section "3. Protective
zone".
CAUTION:
• Perform grounding.
Do not connect the ground wire to a gas pipe, water
pipe arrester or telephone ground wire. Defective
grounding could cause an electric shock.
• Do not install the unit in a place where an inflam-
mable gas leaks.
F
If gas leaks and accumulates in the area surround-
ing the unit, it could cause an explosion.
• Install a ground leakage breaker depending on the
installation place (where it is humid).
If a ground leakage breaker is not installed, it could
cause an electric shock.
• Perform the drainage/piping work securely accord-
ing to the Installation Manual.
If there is a defect in the drainage/piping work, wa-
ter could drop from the unit and household goods
could be wet and damaged.
