9 DRAIN PIPING
9.1 DRAIN DISCHARGING BOSS
When the base of the outdoor unit is temporarily utilized as a
drain receiver and the drain water in it is discharged, this drain
boss is utilized to connect the drain piping.

10.1 GENERAL CHECK
1 Ensure that the eld-supplied electrical components (mains
power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the
electrical data indicated. Make sure that they comply with
national and regional electrical codes.

10% of the rated voltage.
5 Check to ensure that power supply has an impedance low
enough to warranty not reduce the starting voltage more
than 85% of the rated voltage.
6 Check to ensure that the ground wire is connected.
7 Connect a fuse of specied capacity.
