Installation Check
How to Secure the Drain Pipe
1. To prevent vibration and noise, make sure the unit is installed
securely and firmly.
2. Install the unit where the sun does not shine directly on the
unit.
3. The outside of the cabinet must extend outward for at least
11" and there should be no obstacles, such as a fence or
wall, within 20" from the back of the cabinet because it will
prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.
CAUTION: All side louvers of the cabinet must
remain exposed on the outdside of the structure.
4. Install the unit slanted slightly so the back is slightly lower
than the front (about 1/
4"). This will force condensed water
to the outside.
5. Install the unit with the bottom about 30"~60" above the
floor level.
The setting conditions must be checked prior to initial starting.
The following items are especially important checking points when the installation is finished.
1. Grounding wire (Green or Green and Yellow) is provided in the power cord. The green wire must be grounded.
2. Connect to a single-outlet 15A circuit.
(or 20A circuit for Electric Heater Model)
3. To avoid vibration or noise, make sure the air conditioner is installed securely.
4 Avoid placing furniture or draperies in front of the air inlet and outlet.
In humid weather, excess water may cause the Base Pan to
overflow. To drain the water, remove the Drain Cap and secure
the Drain Pipe to the rear hole of the Base Pan. (Figure. 2)

How to Install
Window Requirements
All supporting parts should be secured to
firm wood, masonry, or metal.
1. This unit is designed for installation in standard double
hung windows with actual opening widths of 22" to 36".
The upper and lower sash must open sufficiently to allow
a clear vertical opening of 15" from the bottom of the
sash to the window stool.
2. If storm window presents interference, fasten a 2" wide
wood strip to the inner window sill across the full width of
the sill. The wood strip should be thick enough to raise
the height of the window sill so that the unit can be
installed without interference by the storm window
frame. See Figure. 4. Top of wood strip should be
approximately 3/4" higher than the storm window frame
(STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain properly to the
outside.
3.
Install a second wood strip (approximately 6" long by 11/2"
wide and same thickness as first strip) in the center of the
outer sill flush against the back off the inner sill. This will
raise the L bracket as shown Figure. 4.
4. If the distance between STORM WINDOW FRAME and
WOOD STRIP MOUNTED ON TOP OF INNER SILL is
more than 1", two of wood strip are not necessary.
