• Do not finish strand wire with solder.

8-5 Procedure for Wiring Inside Units

• Referring to the following figure, secure and wire the power and 

transmission wiring using clamps.

• Lay the ground wire so that it will not come in contact with the lead 

wires of the compressor. Other equipment will be adversely 
affected if the ground wire comes in contact with the lead wires of 
the compressor.

• Make sure all wiring do not contact to the pipes (hatching parts in 

the figure).

• The transmission wiring must be at least 50 mm away from the 

power wiring.

• After wiring work is completed, check to make sure there are no 

loose connections among the electrical parts in the control box.

11 When routing remote operating switch wiring through a wiring 

opening

12 Separate by at least 50 mm
13 Stay
14 Perform wiring carefully so that the sound insulation of the com-

pressor will not come off

15 Support

17 Fixed to the rear side of the support with a clamp (field supply)

CAUTION

On completion of electrical work, check that there are no disconnected 
connectors or terminals of any electrical parts in the control box.

INSPECTION AND PIPE INSULATION

For piping work contractor, electrical work contractor, 
and trial run workers

• Never open the shutoff valve until the insulation measurement of 

the main power supply circuit is finished. The measured insulation 
value will become lower if the measurement is made with the shut-
off valve opened.

• On completion of inspection and refrigerant charging, open the 

shutoff valve. The compressor will malfunction if the CONVENI-
PACK is operated with the shutoff valve closed.

9-1 Air Tight Test/Vacuum Drying

Refrigerant is enclosed in the unit.
Be sure to keep both liquid and gas shutoff valves 
closed at the time of an airtight test or vacuum drying of 
the local piping.

[For piping work contractor]
On completion of piping work, make the following inspection precisely.

• To ensure that the CONVENI-PACK withstand pressure properly 

and prevent the penetration of foreign substances, be sure to use 
R410A-dedicated tools.

• Air tight

Pressurize the high-pressure section of the system (liquid piping) 
to 4.0 MPa (40 bar) and the low-pressure section of the system 
(gas piping) to the design pressure (*1) of the indoor unit (field sup-
ply) from the service port (*2) (do not exceed the design pressure). 
The system is considered to have passed if there is no decrease in 
the pressure over a period of 24 hours.
If there is a decrease in the pressure, check for and repair leaks.

• Vacuum drying

Connect a vacuum pump to the service ports (*) of both the liquid 
and gas pipes for at least 2 hours and vacuum the unit down to 
–100.7 kPa or below. Then leave the unit for at least 1 hour at a 
pressure of –100.7 kPa or below and check that the vacuum gage 
reading will not rise. If the pressure rises, there is residual water in 
the system or the system has leakage.

*1 Contact the manufacturer in advance for more information about 

the design pressure of the indoor unit (field supply).

Gauge manifold
Charge hose

• To ensure that the CONVENI-PACK with-

stand pressure properly and prevent the 
penetration of foreign substances (water, 
dirt, and dust), use an R410A-dedicated 
gage manifold and charge hose. R410A-
dedicated tools and R407C-dedicated tools 
are different in screw specification.

Vacuum pump

• Pay the utmost attention so that the pump 

oil will not flow backward into the system 
while the pump is not in operation.

• Use a vacuum pump that can vacuum 

down to –100.7kPa (5 Torr or –755mmHg).

Gas for airtight 
test use

• Nitrogen gas
