D. Installation of Condensate Pipe
1. The condensate pipe shall be installed with an
inclining angel of 5〜10°, so as to facilitate the
drainage of condensate. The joints of the
condensate pipe must be covered by thermal
insulation materials to avoid generation of
exterior condensate.
2. A condensate outlet is located at both the left
and right sides of the indoor unit. After
selecting one condensate outlet, the other
outlet shall be blocked by rubber plug. Bundle
the blocked outlet with string to avoid
leakage, and also use thermal insulation
materials to wrap the blocked outlet.
3. When shipped out from factory, both the
condensate outlets are blocked by rubber
plugs.
E. Air purging and leakage test
1. Take out the nut cover of the inlet for
refrigerant.
2. Connect the tube of the vacuum watch with
the vacuum pump, having the low-pressure
end linking to the inlet for refrigerant.
3. Starting the vacuum pump, when the
indicator turns to-1 bar, closing the low
pressure handle and stopping vacuumize.
Keep for 15 minutes, ensuring the pressure of
the vacuum watch remains.
4. Take out the valve cover of the gas valve
together with the liquid valve.
5. Loosing the cord of liquid valve until the
pressure rise to 0 bar.
6. Dismantle the tube from the cover of the inlet for refrigerant then, tighten the cover.
7. Loose the valve cord of the gas valve as well as the liquid valve entirely.
8. Tighten the valve cover of the gas valve and liquid valve so as to check whether leakage occurred.
F. Installation of Protective Layer of Connecting Pipe
1. To avoid generation of condensate on the
connecting pipe and avoid leakage, the big
pipe and the small pipe of the connecting pipe
must be covered by thermal insulation
materials, be bundled by adhesive tape, and
be isolated from air.
2. The joint connecting to the indoor unit must
be wrapped by thermal insulation material.
There shall be no gap between the
connecting pipe joint and the wall of the
indoor unit. Refer to Figure 4.
Caution:
After the pipes are wrapped by protective materials, never bend the pipes to form very small angle, and
otherwise the pipes may crack or break.
