9.2 power wire connection
The indoor unit and outdoor unit should use separate power
supplies, independent leakage protectors and an all-pole
disconnection device.
Indoor units connecting to the same outdoor unit should use
a uniform power supply, leakage protection devices and
all-pole disconnection device.
POWER IN
The power supply specifications are as follows. See table 9-1&9-2.
If the capacity of the wire is too low, the wire may overheat and the
machine my burn out.

Check the drainage pump for draining water immediately
when the alarm sounds for a high water level. If the water level
cannot come back to below the limit, the air conditioner will stop.
Restart it until turn off the power and drain all the water.
Stop the air conditioner for three minutes and check that
everything is normal. If the drainage hose is poorly located,
water overflow will cause the alarm indicator lamp to flash (for
both cooling and heating or cooling only) and water may leak
from the water pan.
Turn on the power. Then, run the air conditioner in "COOLING"
mode. Listen to the sound of the drainage pump. Check whether
the water discharges well (a lag of 1 min is allowed before
discharging, according to the length of the drainage pipe), and
check whether water leaks from the joints.
8.2 Drainage Test
Check that the drainage pipe is unhindered
Newly built house should be tested before decorating the
ceiling.
1. Remove the test cover, and stow 2000 ml of water to the
water pan through the stow tube.
2.
CAUTIONS: If there is a fault, resolve it immediately.
3.
4.
5. Turn off the power and drain the water away.
The drainage plug is used to empty the water pan for maintenance
of the air conditioner. Fix it in position at all times when running to
avoid leaks.
The power wire type designation is H05RN-R / H07RN-F or above.
9. ElECTRICAL CONNECTION
CAUTION
9.1 Electrical wiring
The power supply of indoor unit must within normal voltage range.
External wiring of the indoor unit must be grounded, so the power
wire of the outdoor unit must be reliably connected to the external
grounding wire.
Before completing the wiring, an all-pole disconnection device
must be installed.
Electrical wiring must be performed by an electrician according
to the wiring label.
Install the electrical leakage device according to national
regulations.
Arrange power wires and communication wires so they do not
interfere with each other. Connection pipes and valves should
not come into contact.
When all electrical wiring is completed, power on the unit after
confirming that all wires are connected correctly and fixed tightly.
Select an appropriate connection wire according to specification
requirements. Do not parallel connect two wires, unless the
welding joint is well welded and wrapped with insulating tape.
Every pole of the all-pole disconnection device should have at
least 3 mm separation distance. Install a leakage protector with
a rating above 10 mA when completing the wiring.
Before connecting the wire, switch off the power. Otherwise it
may cause electric shocks.
