Step six: neaten the pipes
1. The pipes should be placed along the wall,
bent reasonably and hidden possibly. Min.
semidiameter of bending the pipe is 10cm.
2. If the outdoor unit is higher than the wall
hole, you must set a U-shaped curve in the
pipe before pipe goes into the room, in
order to prevent rain from getting into the
room.
● The through-wal height of drain hose
shouldn't be higher than the outlet
pipe hole of indoor unit.
● Slant the drain hose slightly dow-
nwards. The drain hose can't be
curved, raised and uctuant, etc.
● The water outlet can't be placed
in water in order to drain smoothly.

Vacuum pumping
Leakage detection
1. Remove the valve caps on
the liquid valve and gas
valve and the nut of refri gerant charging vent.
2. Connect the charging hose
of piezometer to the refri-
gerant charging vent of gas
valve and then connect the
other charging hose to the
vacuum pump.
3. Open the piezometer com-
pletely and operate for
10-15min to check if the
pressure of piezometer re-
mains in -0.1MPa.
4. Close the vacuum pump
and maintain this status for
1-2min to check if the pres-
sure of piezometer remains
in -0.1MPa. If the pressure decreases, there may be leakage.
5. Remove the piezometer, open the valve core of liquid valve and gas valve
completely with inner hexagon spanner.
6. Tighten the screw caps of valves and refrigerant charging vent.
7. Reinstall the handle.

2. With soap water:
If leakage detector is not available, please use soap water for leakage detection.
Apply soap water at the suspected position and keep the soap water for more
than 3min. If there are air bubbles coming out of this position, there's a leakage.

Check after installation
Test operation
● Check according to the following requirement after nishing installation.
Items to be checked Possible malfunction
Has the unit been installed rmly? The unit may drop, shake or emit noise.
Have you done the refrigerant leakage
test?
It may cause insufcient cooling
(heating) capacity.
Is heat insulation of pipeline sufcient?
It may cause condensation and water
dripping.
Is water drained well?
It may cause condensation and water
dripping.
Is the voltage of power supply according to the voltage marked on the
nameplate?
It may cause malfunction or damaging
the parts.
Is electric wiring and pipeline installed
correctly?
It may cause malfunction or damaging
the parts.
Is the unit grounded securely? It may cause electric leakage.
Does the power cord follow the speci-
cation?
It may cause malfunction or damaging
the parts.
Is there any obstruction in the air inlet
and outlet?
It may cause insufcient cooling
(heating) capacity.
The dust and sundries caused during
installation are removed?
It may cause malfunction or damaging
the parts.
The gas valve and liquid valve of
connection pipe are open completely?
It may cause insufcient cooling
(heating) capacity.
1. Preparation of test operation
● The client approves the air conditioner.
● Specify the important notes for air conditioner to the client.
2. Method of test operation
● Put through the power, press ON/OFF button on the remote controller to start
operation.
● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check
whether the operation is normal or not.
● If the ambient temperature is lower than 16℃, the air conditioner can’t
start cooling.
33
1. Standard length of connection pipe
● 5m, 7.5m, 8m.
4. The additional refrigerant oil and refrigerant charging required after prolonging
connection pipe
● After the length of connection pipe is prolonged for 10m at the basis of
standard length, you should add 5ml of refrigerant oil for each additional 5m
of connection pipe.
● The calculation method of additional refrigerant charging amount (on the basis
of liquid pipe):
● Basing on the length of standard pipe, add refrigerant according to the
requirement as shown in the table. The additional refrigerant charging amount
per meter is different according to the diameter of liquid pipe. See the
following sheet.
Additional refrigerant charging amount = prolonged length of liquid pipe ×
additional refrigerant charging amount per meter
