　　　Maintenance

!

CAUTION

1. Cleaning of indoor unit
Wipe the indoor unit with a dry soft cloth damped

in 40℃　water.

2. Front cover cleaning

In terms of the operation shown as picture,
unload the front cover.

Cuts and abrasions may result from contact with the sharp components inside the appliance.

Clean the air filter once very two weeks.

3. Cleaning the air filter

Raise the front cover and take out the air filter.

After cleaning the dirt of the air filter, please
wash the air filter by water then dry it.

22

11

Wipe and dry the front cover with a sponge or
similar substance.
Mild detergent can be used for excessive dirt.

In terms of the operation shown as picture, load
the front cover.

Install the air filter and hold both sides of the
front cover as shown by the arrows.

14

　　　Maintenance

4. Cleaning and replacement of air fresh filter
Raise the front cover and take out the air filter.

Take out the dirty air fresh filter from the air filter.
There are two kinds of air fresh filter, the
photocatalyst health filter can be used again after
washed by water and dried; the electrocstatic air
cleaning filter should be replaced with a new one.

5. Long-term cessation
Warm and air the inside to dry the appliance.

Before unplug the appliance for cessation of

operation, press "ON/OFF" button to cease the
appliance, then pull out the power plug.

Install the air fresh filter onto the air filter and

close the front cover as shown by the arrows.

Cl ean the air filter and take out the air fresh filter.

Remove the batteries from the remote control
unit.

15

　　　Wise Operation

Blockage of the air inlet or outlet may reduce the
cooling capacity of the appliance.

Cooling capacity can be reduced by
accumulated dirt on the air filter. Clean the air
filter when noise is heard or water drops
accumulate at the outlet.

Excessively low temperature setting may be
harmful to health and will result in high power
consumption.

Make sure windows and doors are properly
closed. Draft strips are recommended for use in
summer .
Window blind reduces 15% of sunlight and
window strips reduce 50%.

Adjust the wind direction to level for cooling.
Please use the timer reasonably to save
consumption.

16

Properly set the temperature.
When setting for cooling, the most desirable
difference between inside and outside
temperature is 5 . 1 increase of the set
temperature will save 10% of power
consumption.

Before drilling, do not fix the back cover onto the wall.

2) According to direction of the tube ,drilling for tubes according

to the location of the appliance. It is recommended that the
rear right be used for wiring and drilling.

3) Drill a 65mm hole in the wall (Figure 6), make sure the hole is

inclining to the outside .

Indoor Outdoor

2) Unload the bottom cover of indoor unit with flat screw
driver, and according to direction of lining tube, leave the
cutting part of left bottom or right bottom cover with
saw.(figure 10)

Before drilling, make sure that
there is no electric cable or pipe

!

CAUTION

in the area of the wall where the
hole is to be drilled.

3.3 Installation of the back cover

1) check with a spirit level that the back cover is installed
horizontally. (Figure 7)

Figure 7

2) fix the back cover to the wall with the screws provided. (Figure

8). Make sure that the back cover is firmly fixed to he wall.

Figure 8

3.4 Install the indoor unit

1) Thread the cable through the hole in the wall, an additional
13cm of slack power cable should remain inside the room.
(Figure 9)

3) Bind the electrical cable drainage hose, refrigerant tube, air
exchange tube together tightly with white adhesive tape;
the electrical cable, refrigerant tube and the electrical cable
are fixed on the back of indoor unit with wedged slab, bend
the refrigeration tube and make the electrical cable and the
air exchange tube through hole of the wall smoothly(figure

11).

3.5 Wiring

(1)Before wiring, make sure the rated voltage indicated on the

nameplate conforms to the local power voltage.

(2)Wiring should be carried out in accordance with the

instructions on the electrical schematic diagram (Figure 14).

3.6 Wiring connection of the indoor unit

1) Hold pull and open the front cover.

2) Release the screws and open the wire distribution cover

(Figure 15).

3) Connecting cable should be placed along the back of the

indoor unit to the front for connection.

4)Connect the wire distribution terminals and corresponding

terminals .(Figure 16)

WARNING

!

Wiring for connection of the indoor unit and the outdoor unit

should be conducted in accordance with local regulations.
Wiring connections must be fitted firmly.
The electrical wires should not be in contact with any of the

refrigeration tubes, compressor or other moving parts or

components.
The appliance must be connected to a good earth.

4. INSTALLATION OF THE OUTDOOR UNIT

Properly locate the outdoor unit as described by the Section 2.
If the outdoor unit is to be mounted on the wall ,make sure that
the wall and the support are strong enough for the appliance.
Wiring Connection

1) Release the fixing screws and take off the side cover.

2) Connect the terminals on the heap pump as required in the
Figure 14 and the Figure 17:

3) Always save an extra 10cm length of the electrical cable:

4) Earth the appliance according to related regulations of
electrical engineering:

5) Fix the connected terminals with clips and replace the side
cover if the connection is assured according to the wiring
diagram:

Figure 16

5) Check the connections and then fasten the distribution
cover and replace the front cover finally.

5.REFRIGERANT TUBE

5.1 Flaring the tube

(1) Cut the tube with a tube cutter to the desired length

(30.50cm is recommended)

(2) Smooth the edge of the copper tube with a reamer or a file.

Hold the pipe vertically with one end downward to make
sure that no copper scraps fall into the copper tube.

5.3 Heat insulation of the refrigerant tube

All refrigerant tubes must be insulated heat with at least 8mm
thick insulation materials. (Figure 22)

5.4 Wrapping the tubes

(1) Tie the two refrigeration tubes (including electrical wire if

permitted as regulated), water drainage hose with white
tape.

(2) Wrap half of the tubes outside the room starting from the

end. (Figure 23)

5.2 Connection of the tubes

(1) The sealing tube must be used to prevent dust or water

from getting into the tube.

(2) Before connecting the tube, apply some refrigerant oil on

the surface of the flared tube and connections to prevent
air leakage.( Figure 20)

(3) Align the connecting tube and the flared tube, and then

turn the tapered nut to connect tightly. (Figure 21)

Application

of refrigerant oil

(4) Fasten the nuts with a spanner.

(3) Fix the wrapped tubes on the wall in clips with a space of

120cm.
Note: Do not tie the tubes too tight as this may reduce heat
insulation. Separate water drainage hose and refrigeration
tubes to prevent formation of water droplets.

5.5 Ending of installation

After completion of wrapping and insulation, seal the hole on
the wall with a suitable sealant.

5.6 Discharge gas

Place appliance A and then B. Air purging method is as
follows:
(1) Turn down the nuts on the wide and narrow tubes.
(2) Loose the nut of the flared wide tube one complete turn

with a spanner.
(3) Turn counterclockwise to open the core of the valve with a

socket screw wrench. Some gas will come out from under

the nut of the flared end of the wide tube. Tighten the nut

10 to 15 seconds later.
(4) Test for leakage at the tube connector with soapy water or

a meter. If there is no leakage, turn counterclockwise to

open the tube core of the valve on the wide tube with a

socket screw wrench.
(5) Tighten the nuts on the wide , narrow tube valves and the

valve cover.

Please contact the technical service for further information.
