Notes on Installation
Be sure to secure the valve body by using its structure with the suspension bolt, etc.
Install the valve body within a distance of 98 ft. from the indoor unit.
Some refrigerant noise will be produced. Therefore in hospitals, libraries, hotel guest rooms, and other quiet locations, it is
recommended that the solenoid valve kit be installed on the ceiling reverse side of a hallway or another location separated
from the room.
When installing the valve body, install with the top surface facing up. Secure 7-7/8" or more of space to the front so that the
front service panel can be removed.
If the supplied suspension hook will not be used, and other fastening devices will be attached in the fi eld, use the 4 screw
holes on the top surface. DO NOT use any long screws other than the supplied screws. Use of other screws may puncture
the internal tubing, resulting in refrigerant leakage.
Do not block the air holes.
