◆Install Outdoor Unit
Power Cable Connection
1. Remove the handle at the right side plate of the outdoor unit
(one screw).
2. Remove the cable clamp, connect the power connection cable
with the terminal at the row of connection and make the
connection. The fitting line distributing must be consistent
with the indoor unit.
3. Use cable clamp to make the cable connection cable.
4. Confirm the fitting lines are properly installed.
5. Install the handle (fixed by one screw).
Notes:
• Improper line connection may cause failure of some electrical
components and parts
• When fixing the cable, a certain degree of play shall be
maintained for the cable between the connection point and the
fixing point.
Vacuum – Pumping and Leakage Inspection
1. Remove the nut cover at the shutoff valve.
2. Align with the center of the fitting pipe and manually
tighten the conical nut sufficiently.
3. Use spanner to tighten the conical nut.
4. Remove the liquid valve cap, the gas valve cap and the
nut of refrigerant charging mouth.
5. Use inner hexagon spanner to twist off the liquid valve
body and at the same time use screwdriver to open the valve
core of the liquid valve. Now gas shall flow out.
6. After gas continues flowing out for about 15 second and
refrigerant gas begins to flow out, close the valve core and
tighten the nut of refrigerant charge mouth.
7. Completely open the valve body of the liquid valve and the
gas valve. （See Fig 12）
8. Turn and tighten the valve cap, then use soap water or a leak
detector to check if there is gas leakage at the outdoor and
indoor units and the pipeline connections.
9. If conditions permit, use a vacuum pump to exhaust air in
the unit from the valve core. （See Fig 13）
Draining of Condensate Water of Outdoor Unit
When the air-conditioning unit is in the heating mode, the
condensate water generated at the outdoor unit and the water
generated by defrosting shall be drained through the drainage
pipe to proper place.
Installation methods: As shown in Figure, insert the drainage
joint of the outdoor unit into the Φ25 hole on the base plate.
Connect the drainage pipe to the drainage mouth so as to drain
the condensate water and water generated by defrosting to
proper place.
