Precautions for outdoor unit combinations
Refer to [Fig. 9.2.2] for the positioning of twinning pipes.
[Fig. 9.2.2]
<A> Make sure the pipes from the twinning pipe to the outdoor unit are sloped downwards (high-pressure side only).

Make sure the slope of the twinning pipes are at an angle within ±15° to the ground.
If the slope exceeds the specifi ed angle, the unit may be damaged.

Caution:
Do not install traps to prevent oil backfl ow and compressor start-up failure.
•
Do not install solenoid valves to prevent oil backfl ow and compressor start-up failure.
•
Do not install a sight glass because it may show improper refrigerant fl ow.
•
If a sight glass is installed, inexperienced technicians that use the glass may overcharge the refrigerant.
