Ball Valve Installation (for refrigerant R410A only)
Check the size of the ball valve set you separately purchased.
Model name
BV-RXP56AG
BV-RXP160AG
These valves are flare-nut type.
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.
CAUTION
2. Flare nut tightening
The flare nut on the service port side is fully
tightened. 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.
