Tightening torque
The sizes of the shutoff valves on each model and the tightening torque
for each size are listed in the table below.
<Size of Shutoff Valve>
(Refer to figure 28)
1. Service port
2. Cap
3. Hex holes
4. Shaft (valve body)
5. Seal section
To open
1.
Remove the cap and turn the shaft counterclockwise with the hexa-
gon wrench.
2.
Turn it until the shaft stops.
3.
Make sure to tighten the cap securely.
(For the tightening torque, refer to the item <Tightening Torque>.)
To close
1.
Remove the cap and turn the shaft clockwise with the hexagon wrench.
2.
Securely tighten the valve until the shaft contacts the main body seal.
3.
Make sure to tighten the cap securely.
(For the tightening torque, refer to the item <Tightening Torque>.)

[How to Check How Many Units are Connected]
It is possible to find out how many indoor or outside unit in the system are turned on by operating the push button on the PC-board (A1P) of outside
unit (In case of multi system master unit).
Follow the procedure below to check how many indoor or outside units are turned on.
NOTE
Press the “MODE button” (BS1) if you get confused while operating.
This returns to Setting Mode 1 (H1P : OFF, default).
11-2 Procedure of Adding Refrigerant charging and
check operation
WARNING Electric Shock Warning
• Make sure to close the EL. COMPO. BOX lid before turning on the
power.
• Perform the setting on the PC-board (A1P) of the outside unit and
check the LED display after the power is on via the inspection door
which is in the EL. COMPO. BOX lid.
(Refer to figure 29)
1. EL. COMPO. BOX (1)
2. Inspection door
3. EL. COMPO. BOX (1) lid
4. LED (H1~8P)
5. Push button(BS1~5)
6. Lift the protruding part to open the inspection door.

(1) Press the MODE button (BS1) once at Setting Mode 1 (H1P : off), and set the MON-
ITOR MODE (H1P : Blinking).
jhhhhhh
(2) Press the SET button (BS2) the number of times until the
LED display matches that at right.
For checking the number of
outside units : eight times
jhhihhh
For checking the number
of indoor units : five times
jhhhihi
(3) Press the RETURN button (BS3) and read the number of units from the display of
H2P through H7P.
[Reading Method]
The display of H2P through H7P should be read as a binary number, with j standing
for “1” and
h standing for “0”.
j ∗∗∗∗∗∗
jhjhjjh
(4)
Press the MODE button (BS1) once. This returns to Setting Mode 1 (H1P : OFF, default).
hhihhhh
Ex: For the LED display at right, this would be “010110”,
which would mean 22 units are connected.
Note: “000000” indicates 64 units.
32 × 0 + 16 × 1 + 8 × 0 + 4 × 1 + 2 × 1 + 1 × 0 = 22 units
