counted. E.g. 16ports=SV8A+SV4A+SV4A.
d At least one indoor unit must be connected to a SV unit
(SV6A and SV8A: always start from one of the first four
ports).
e Combine two ports when indoor unit capacity is over 140
except when SV1A is used. Refer to the table below.
f Direct connection to the outdoor unit. For more

15.2 Connecting the refrigerant piping
15.2.1 Using the stop valve and service port
To handle the stop valve
Take the following guidelines into account:
▪ The gas and liquid stop valves are factory closed.
▪ Make sure to keep all stop valves open during operation.
▪ Do NOT apply excessive force to the stop valve. Doing so may
break the valve body.
To open the stop valve
1 Remove the dust cap.
2 Insert a hexagon wrench into the stop valve.
3 FULLY turn the stop valve counterclockwise and tighten until
the correct tightening torque value is achieved (see "Tightening
torques"[432]).
NOTICE
Stop valves need to be opened on torque specified in this
manual. It is not allowed to turn valve "a quarter turn" back
when opening it.
4 Install the dust cap.
Result: The valve is now open.
NOTICE
Reinstall dust cap to prevent aging of O-ring and risk of
leakage.
To close the stop valve
1 Remove the stop valve cover.
2 Insert a hexagon wrench into the stop valve and turn the stop
valve clockwise.
3 When the stop valve cannot be turned any further, stop turning.
4 Install the stop valve cover.
Result: The valve is now closed.
To handle the service port
▪ Always use a charge hose equipped with a valve depressor pin,
since the service port is a Schrader type valve.
▪ After handling the service port, make sure to tighten the service
port cover securely. For the tightening torque, refer to the table
below.
▪ Check for refrigerant leaks after tightening the service port cover.
