Open the air inlet panel. Remove the lid. Remove the wiring clamp. Connect the connecting wire securely to the termin
al block.
1)
Connect the connection wire securely to the ter
minal
block. If the wire is not affixed completely, conta
ct will be
poor, and it is dangerous as the terminal block
may heat
up and catch fire

2)
Take care not to confuse the terminal numbers
for indoor
and outdoor connections.
Fix the connecting wire by wiring clamp. Attach the lid. Close the air inlet panel.

Use a flare tool designed for R410A or a conventional flare tool. Please note that measurement B (protrusion from the flaring block) will vary depending on the type of a flare tool in use
.
If a conventional flare tool is used, please use a copper pipe gauge or a similar instrument to check protrusion so that you can keep measurement B to a correct value.

INSTALLATION TEST CHECK POINT
S
After installation
The power supply voltage is correct as the rating. No gas leaks from the joints of the operation valve
.
Power cables and crossover wires are securely fixed to the terminal board
.
Operation valve is fully open. The pipe joints for indoor and outdoor pipes have been insulated. Air conditioning operation is normal
.
No abnormal noise
.
Water drains smoothly. Protective functions are not working. The remote control is normal.
Operation of the unit has been explained to the customer. (Three-minutes restart preventive timer
)
When the air conditioner is restarted or when changing the operation, the uni
t
will not start operating for approximately 3 minutes
.
This is to protect the unit and it is not a malfunction.
Test ru
n
Check the following points again after completion of the installation, and before turning on the power. Conduct a test run agai
n and ensure that the unit operates properly
.
At the same time, explain to the customer how to use the unit and how to take care of the unit following the user
’s manual.

• Cover the indoor unit s flare-connected joints, after they are checked for a gas leak,
with an indoor unit heat insulating material and then wrap them with a tape with an attached insulation pad placed over the heat insulating material
’s slit area
.
Cover the coupling with insulator and then cover it with tapes.
