The Refrigerant
To have a functional air conditioning unit, a special refrigerant circulates in the system. The used refrigerant
is the fluoride R32, which is specially cleaned. The refrigerant is flammable and inodorous. Furthermore, it
can lead to explosion under certain conditions. But the flammability of the refrigerant is very low. It can be
ignited only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere. The
greenhouse emissions are also lower. R32 has very good thermodynamic features which leads to a high
energy efficiency. The unit therefore needs less filling.
WARNING:
•Keep ventilation openings clear of obstruction.
•Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
•Should repair be necessary, contact your nearest authorized Service Centre. Any repairs carried
out by unqualified personnel may be dangerous.
•For repairs, strictly follow manufacturer’s instructions only.
•Appliance shall be installed, operated and stored in a room with a floor area larger than the
recommended area (Please refer to table “1” in section of “Refrigerant Safety Precautions”).
WARNING:
•The appliance shall be stored in a room without continuously operating ignition sources (for
example: open flames, an operating gas appliance or an operating electric heater).
•Do not pierce or burn the unit.
•Appliance is filled with flammable gas R32.
•Be aware that refrigerants do not contain odor.
•When maintaining or disposing the unit, the refrigerant inside the system must be eliminated.
Refrigerant should be recovered. It can’t be discharged freely.
•No open fire (fired equipment such as electrical heater and gas stove etc.) or any equipment (e.g.
switch) that might generate arc should be around the appliance.
NOTE: Anyone who is involved with working on or breaking into a refrigerant circuit should hold a current
valid certificate from an industry-accredited assessment authority, which authorizes their competence to
handle refrigerants safely in accordance with an industry recognized assessment specification. Servicing
shall only be performed as recommended by the equipment manufacturer. Maintenance and repair
requiring the assistance of skilled personnel shall be carried out under the supervision of the person
competent to use flammable refrigerants.

Installation Procedure
NOTE: Some models require installation of a top guide rail. If your model does, use 4 Type A screws to fix
the upper rail at the outer case of air conditioner.
NOTE: The top rail and the side panels are offset to provide the proper pitch to the rear of (5/16”). This is
necessary for proper condensed water utilization and drainage. Even if you are not using the side panels,
the rear pitch must be maintained!
Step 1:
Place unit on floor, a bench or a table. There is a Left-side and Right-side Filler Panel. Be sure to use the
proper panel for each side. When installed, the flange for securing the panel in place in the windowsill will
be facing into the room.
a. Hold the side Panel in one hand and gently pull back the center to free the open end. See
Figure 1.
b. Slide the free end “T” section of the panel directly into the cabinet as shown in Figure 2. Slide
the panel down. Be sure to leave enough space to slip the top and bottom of the frame into
the rails on the cabinet.
c. Once the panel has been installed on the side of the cabinet, make sure it sits securely inside
the frame channel by making slight adjustments. Slide the top and bottom ends of the frame
into the top and bottom rails of the cabinet. See Figure 3.

Figure 4B
Figure 5
Installation Procedure
d. Slide the panel all the way in and repeat on the other side.
NOTE: Your air conditioner is designed to install in standard double hung windows with opening widths of
22” to 36” (Figure 4A, Figure 4B). Lower sash must open sufficiently to allow a clear vertical opening of
minimum 15 ½”. Side louvers and the rear of the air conditioner must have clear air space to allow enough
airflow through the condenser, for heat removal. The rear of the unit must be outdoors, not inside a
building or garage.
Step 2:
If your window is a weather-proof type window, the height of window frame is higher than the windowsill,
which will affect the installation of air conditioner. In this case, before installing the air conditioner, add
wooden strap on the windowsill, and fix the wooden strap to the windowsill.
Specification of wooden strap (see Figure 5):
•Width: about 2”
•Length: same to the inner frame size of window
•Height: Put the wooden strap on the windowsill, top part of wooden strap and window frame
should be at the same horizontal level, or higher than the top part of window frame for about
1/2".

Installation Procedure
Step 3:
Cut the sealing strip into proper length. Stick the sealing strip to the lower part of the window frame (see
Figure 6).
Step 4:
Keep a firm grip on the air conditioner, carefully place the unit into the window opening so the bottom
of the air conditioner frame is against the windowsill (Figure 7A and Figure 7B). Carefully close the
window behind the top rail of the unit.
Step 5:
Extend the side panels out against the window frame (see Figure 8A for wooden windows or Figure 8B for
Vinyl-Clad windows).

Installation Procedure
Step 6:
Place the frame lock between the frame extensions and the windowsill as shown (see Figure 9A for wooden
windows or Figure 9B for Vinyl-Clad windows).
Step 7:
a. For wooden windows: Drive locking screws through the frame lock and into the windowsill (Figure
10A).
NOTE: To prevent windowsill from splitting, drill 1/8” (3 mm) pilot holes before driving screws.
Drive locking screws through frame holes into window sash (Figure 10B)
b. For Vinyl-Clad windows: Drive locking screws through the frame lock and into the window sash
(Figure 10A).
NOTE: Before driving the screws, use a drill to drill 5 holes through the holes in the frame lock
and frame extensions into the windows sash as shown (Figure10B).

Figure 13B
Installation Procedure
Step 8:
To secure lower sash in place, attach right angle sash lock with screw as shown (Figure 11).
NOTE: It is difficult to lock the windows with the sash lock for Vinyl-Clad windows, so you can use window
itself to lock.
Step 9:
Cut the sealing strip the length of window. Plug the sealing strip between glasses and window to prevent
rain and insects getting into the room (Figure 12).
NOTE: if the sealing strip is not suitable for your window, it can be replaced.
Step 10:
Check that air conditioner is tilted back about 1/4” to 1/2” (tilted about 2° to 4° downward to the outside,
see Figure 13A and Figure 13B). After proper installation, condensate should not drain from the overflow
drain hole during normal use, correct the slope otherwise.

Figure 14
Installation Procedure
Step 11:
Trim the weather seal with a proper length peel off the protective backing and plug any gaps if needed
as shown Figure 14.
Step 12:
To get the maximum cooling efficiency, the air conditioner is designed to splash the condensate on the
condenser coil. If the splashing sound annoys you, you can provide an outside drain by using the following
procedure, which may however cause a small loss of performance.
a. The air conditioner has the drainage gasket (Figure 15A).
b. Remove the drainage gasket from the body base plate (Figure 15B).
