Test run
Carry out test run referring to the installation manual enclosed with indoor/outdoor unit.
1. After deciding the installation location, carry out flaring work of liquid pipe and apply thin layer of refrigerant oil (procure locally) to
the flared seat surface.
2. Connect the field refrigerant piping.
3. Wrap the enclosed pipe cover 3around the liquid pipe connection, pushing it on the outside of External LEV Box
1 .
4. Secure both ends of pipe cover 3with the enclosed bands 4to make sure it is insulated.
w When flare tools for R22, R407C are used for R410A flaring work, refer to the table above. The size adjustment gauge can be used to secure A measurements.
Apply thin layer of ester oil, ether oil or alkylbenzene oil to the entire flare seat surface.
wDo not apply it to the screws as it may cause loosening of the flare nut.
Make sure to use the flare nut attached to the unit
(Using commercial item may cause breaks).
2-2 Connecting pipes
At factory shipment, the cable for LEV in the indoor unit is connected to the connector CN60 on the indoor controller board.
Remove the cable for LEV in the indoor unit and connect cable No.1(100mm) for External LEV box 1to the connector

And certain models have connector CN60 which doesn’t fit cable No.1 as shown below, then replace cable No.1 (100mm)
with the provided cable No.2(100mm) 6.
Bind the removed cable for LEV with fastener 5and place it in the electrical box.
If you turn on the indoor unit before disconnecting the cable for LEV in the indoor unit, the LEV in the indoor unit will close.
(At factory shipment, the LEV is fully open.)
If the LEV in the indoor unit closes, you must use the maintenance tool to open the LEV fully.
Consult your dealer for service.
Remove the relay connector in electrical box. Connect the lead wire of the connector (CN60) to the connector of the cable
(Accessory:5300mm) of External LEV Box 1. Bind the removed lead wire of LEV with fastener 5 and place it in the electrical
box. Remove the cable No.1 (100mm) since it is unnecessary.
The replacement of the
