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 cover3 around the liquid pipe connection, pushing it on the outside of External LEV Box1.
4. Secure both ends of pipe cover3 with the enclosed bands4 to 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 ma
y 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 connector for LEV in the indoor unit is connected to the connector (CN60) on indoor controller
board. Replace the connector (CN60) with the white connector of the cable (accessory: 100mm) for External LEV Box1.
Bind the removed lead wire of LEV with fastener5 and place it in the electrical box.
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 Box1. Bind the removed lead wire of LEV with fastener5 and place it in the electrical
box. Remove the cable (accessory: 100mm) since it is unnecessary.
