1. Installing the ball valve
(1) If the ball valve is to be installed for indoor unit
extension, or near an indoor unit, install it so that
the service port faces the indoor unit side.
(This facilitates indoor unit leak testing and vacu-
um procedures.)
Install the ball valve as close as possible to the
distribution joint.
This ball valve is for use
CAUTION
only in systems that utilize
refrigerant R410A. The ser-
vice port connection size is
ø7.94. The face-to-face dis-
tance between the ø12.7 or
ø15.88 flare nuts is 26 mm
or 29 mm, respectively.
Be sure to use only the
supplied flare nuts. Be
careful to use the correct
tools and materials.
2. Flare nut tightening
The flare nut on the service port side is fully tight-
ened. Recommended tightening torque is
(8~10 N·m).
If the valve is used for extension, it can be used
as-is. In all other cases, use 2 monkey wrenches
in combination to loosen the flare nut.
