indoor unit No.1 system and condenser No.1 system, connect the gas and liquid pipe of same indoor
unit No.2 system and condenser No.2 system.
• If indoor unit is a single-system unit, it is required to number the condenser and indoor unit respec-
tively. This will avoid gas and liquid pipe connection error. Such as No.1 indoor unit connected with
No.1 condenser No.1 system, No.2 indoor unit connected with No.1 condenser No.2 system.
