7 Installation details
7.1 Installation instructions.
Your air conditioner is designed to install in standard double hung windows with opening widths of 23
to 36 inches(584mm to 914mm) (See Fig.1).
Table 1
MODEL
5000~8000Btu/h
10000~12000Btu/h
SIZE
14 (356mm)
15-1/2 (394mm)
Lower sash must open sufficiently to allow a clear vertical
opening of following size (see Table 1).Side louvers and the
rear of the AC 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.
NOTE: Save Carton and these Installation Instructions
for future reference. The carton is the best way to store unit
during winter, or when not in use.
TOOLS NEEDED:
Phillips Screw Driver
Drill(If pilot holes are needed)
CAUTION: When handling unit, be careful to avoid cuts from
sharp metal edges and aluminum fins on front and rear coils.
NOTE: The top rail hardware and the following Fig.A, Fig.B
and Fig.C are not applicable to the units more than 10000Btu/h.
Before installing unit, the top rail must be assembled on the
unit (For <10000Btu/h models only).
Tool Needed: Phillips Screwdriver
A: Remove the air conditioner from the carton and place on a
flat surface.
B: Remove top rail from the rear of the packaging material as
shown in Fig. A
C: Align the hole in the top rail with those in the top of the
unit as shown in Fig.B
D: Secure the top rail to the unit with the 3/8 Screws as
shown in Fig.C.
NOTE: For safety reasons, all four(4) screws MUST be
securely fastened.

7.2 How to install.
NOTE: Top rail and Sliding Panels at each side are offset to provide the proper pitch to the rear of
(5/16 ). This is necessary for proper condensed water utilization and drainage. If you are not using the
Side Panels for any reason, this pitch to the rear must be maintained.
1. Place unit on floor, a bench or a table. There is a Left and Right Window Filler Panel- be sure
to use the proper panel for each side. When installed the flange for securing the panel in place to
the window sill will be facing into the room.
A. Hold the Accordion Panel in one hand and gently pull back the center to free the open end. See
Fig.1.
B. Slide the free and (“I” section) of the panel into the cabinet as shown in Fig. 2A, 2B & 3. 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 ends of the frame into the top and bottom rails of the cabinet. Fig.4.
D. Slide the panel all the way in and repeat on the other side.
NOTE: If storm window blocks AC, see Fig. 13.

2. 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 window sill (Fig.5). Carefully close the window
behind the top rail of the unit.
3. Extend the side panels out against the window frame (Fig.6).
4. Place the frame lock between the frame extensions and the window sill as shown (Fig.7).
Drive 3 / 4(19mm) or 1 / 2(13mm) locking screws through the frame lock and into the sill
(Fig.8).
NOTE: To prevent window sill from splitting, drill 1 / 8 (3mm) pilot holes before driving screws.
FIG.5
FIG.6

18
5. Drive 1 / 2 (13mm) locking screws through frame holes into window sash (Fig.9/10)
6. To secure lower sash in place, attach right angle sash lock with 3 / 4 (19mm) or 1 / 2 (13mm) screw
as shown (Fig.11).
7. Cut foam seal and insert in the space between the upper and lower sashes (Fig.12).
If AC is Blocked by Storm Window
Add wood as shown in Fig.13, or remove storm window before air conditioner is installed. If Storm
Window Frame must remain, be sure the drain holes or slots are not caulked or painted shut.
Accumulated Rain Water or Condensation must be allowed to drain out.
Removing AC From Window
Turn AC off, and disconnect power cord. Remove sash seal from between windows, and
unscrew safety lock. Remove screws installed through frame and frame lock. Close (slide) side panels
into frame. Keeping a firm grip on air conditioner, raise sash and carefully rock air conditioner
backward to drain any condensate water in base of unit. Be carefully not to spill any remaining water
while lifting unit from window. Store parts with air conditioner.
