Caution
• Be sure to use crimp-style terminal with insulating sleeves for
connections. (See the figure below.)
• For wiring, use the designated power wire and connect firmly,
then secure to prevent outside pressure being exerted on the ter-
minal board.
• Use an appropriate screwdriver for tightening the terminal screws.
A screwdriver with a small head will strip the head and make
proper tightening impossible.
• Over-tightening the terminal screws may break them.
See the following table for the tightening torque of the terminal
screws.
• When pulling the ground wire out, wire it so that it comes through
the cut out section of the cup washer. (See the figure below.) An
improper ground connection may prevent a good ground from
being achieved.
• When two wires are connected to a single terminal, connect them
so that the rear sides of the crimp contacts face each other. Also,
make sure the thinner wire is on top, securing the two wires simul-
taneously to the resin hook using the included clamp (1).
7-6 Procedure for Wiring Inside Units
• Referring to figure 27, secure and wire the power and transmis-
sion wiring using the included clamp (1), (2), and (3).
(Refer to figure 27)
1. Retain with accessory clamp (3).
2. Electric conduit
3. When routing out the power/ground wires from the left
side.
4. When routing out the transmission wiring from the open-
ing for piping.
5. When routing out the power/ground wires from the front.
6. Clear over 50 mm.
7. When routing out the transmission wiring from the
knockout hole.
8. Retain to the back of the column support with the acces-
sory clamp (2).
9. When routing out the power/ground wires from the right
side.
10. Power wiring
11. Transmission wiring
12. Ground wire
13. Secure to the back side of the support beam using the
accessory clamp (1).
14. Retain to the back of the column support with the acces-
sory clamp (2).
15. When wiring, exercise sufficient caution not to detach the
acoustic insulators from the compressor.
Caution
• The transmission wiring must be at least 50 mm away from the
power wiring.
• Make sure all wiring do not contact to the pipes (hatching parts in
the figure 27).
• After wiring work is completed, check to make sure there are no
loose connections among the electrical parts in the
EL.COMPO.BOX.
8. AIR TIGHT TEST AND VACUUM DRY-
ING
Note
• Always use nitrogen gas for the airtightness test.
• Absolutely do not open the shutoff valve until the main power ciruit
insulation measurement has been completed. (measuring after
the shutoff valve is opened will cause the insulation value to drop.)
8-1 Preparations
<Needed tools>
<The system for air tight test and vacuum drying>
• Referring to figure 28, connect an nitrogen tank, refrigerant tank,
and a vacuum pump to the outdoor unit.
The refrigerant tank and the charge hose connection to refrigerant
charge port or the valve A, C in figure 28 are needed in “11. ADDI-
TIONAL REFRIGERANT CHARGE AND CHECK OPERATION”.
• The shutoff valve and valve A~C in figure 28 should be open or
closed as shown in the table below.
(Refer to figure 28)
1. Gauge manifold
2. Nitrogen
3. Measuring device
4. R410A tank (with siphon)
5. Vacuum pump
6. Charge hose
7. Liquid side shutoff valve
8. Gas side shutoff valve
9. Shutoff valve service port
10. Valve B
11. Valve C
12. Valve A
13. Outdoor unit
14. Refrigerant charge port

•
To prevent entry of any impurities and insure suffi-
cient pressure resistance, always use the special
tools dedicated for R410A.
•
Use charge hose that have pushing stick for con-
necting to service port of shutoff valves or refriger-
ant charge port.
Vacuum pump
•
The vacuum pump for vacuum drying should be
able to lower the pressure to –100.7kPa
(5 Torr –755mm Hg).
•
Take care the pump oil never flow backward into the
refrigerant pipe during the pump stops.
