1.9.4 Installation of outdoor unit
(1) Models SRC40-60ZSX-S
• This installation manual deals with an outdoor unit installation only. For an indoor unit installation, refer to page 48.
• Before installation, read the "SAFETY PRECAUTIONS" carefully and strictly follow it during the installa-
tion work in order to protect yourself.
• The precautionary items mentioned below are distinguished into two levels,
WARNING Indicates a potentially hazardous situation which, if not avoided, can result in serious con-
sequences such as death or severe injury.
CAUTION Indicates a potentially hazardous situation which, if not avoided, can result in personal in-
jury or property damage.
Both mention the important items to protect your health and safety. Therefore, strictly follow them by any means.
• Be sure to use only for residential purpose.

does not exceed the limit (Reference: ISO5149) in the event of leakage.

entrapment, burn or electric shock.
• This unit is designed specifi cally for R410A.
Using any other refrigerant can cause unit failure and personal injury.
• Do not vent R410A into atmosphere.
R410A is a uorinated greenhouse gas with a Global Warming Potential(GWP)=2088.
• Make sure that no air enters the refrigerant circuit when the unit is installed
and removed.
If air enters the refrigerant circuit, the pressure in the refrigerant circuit will become too high, which
can cause burst and personal injury.
• Be sure to use the prescribed pipes, fl are nuts and tools for R410A.
Using existing parts (for R22 or R407C) can cause refrigerant circuit burst resulting in unit failure and
personal injury.
• Be sure to connect both liquid and gas connecting pipes properly before op-
erating the compressor.
Do not open the liquid and gas service valves before completing piping work,
and evacuation.
If the compressor is operated when connecting pipes are not connected and service valves are open,
air can be sucked into the refrigerant circuit which can cause anomalous high pressure resulting in
burst or personal injury.
• Be sure to tighten the fl are nuts to specifi ed torque using the torque wrench.
i T
h g
e t
i n
g n
are nuts with excess torque can cause burst and refrigerant leakage after a long period.
• Take care when carrying the unit by hand.
