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 a wrench to tighten the conical nut.

4. Remove the liquid valve cap, the gas valve cap

and the nut of refrigerant inlet.

5. Use an Allen wrench 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

will flow out.

6. After the gas continues flowing for about 15

second and refrigerant gas begins to flow out,

close the valve core and tighten the nut of

refrigerant inlet.

7. Completely open the valve body of the liquid

valve and the gas valve.

8. Turn and tighten the valve cap, then use soapy

water or a leak detector to check for gas

leakage at the outdoor and indoor units and

pipeline connections.

9. If conditions permit, use a vacuum pump to

pump air in the unit from the valve core.

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 drains through the drainage pipe to the

outlet.

Installation methods: as shown in the figure, insert

the drainage joint of the outdoor unit into the Ø

25 hole on the base plate.

Connect the drainage pipe to the drainage outlet

so as to drain the condensed water and water

generated by defrosting to proper place.
