If the maximum tubing length exceeds 90 m (equivalent length), increase the diameter of the main tubing to the size
in ( ) for both liquid and gas tubes. However, gas tube diameter should not exceed 31.75 mm. (Reducers are available
locally.)

● Gas Cut-off Valve Kit (for 2-WAY multi)
・ SGP-VK32K
The gas cut-off valve kit is installed in the refrigerant
gas tubes (largest tube) between the main tube and
outdoor units, as shown in Fig. 7.
* If a vibration-resistant frame is to be used, refer to
the chapter, using a Vibration-Resistant Frame.
●Solenoid Valve Kit (for 3-WAY multi)
・ ATK-RZP56BGB
・ ATK-RZP160BGB
① Install the solenoid valve kit at a point within 30 m
of the indoor unit.
② For places where quiet is an important
consideration, such as hospitals, libraries, hotels,
etc., we recommend installing the solenoid valve
kit away from rooms, such as in the ceilings of
hallways, to avoid annoyance due to refrigerant
noise.
③ Install an inspection port near the solenoid valve
kit so it can be serviced.
