performing any installation or maintenance
WIRING
Plug power supply cord into a grounded 3-prong [
outlet Do not remove ground prong Do not use an 1
adapter Do not use an extension cord
Failure to follow these instructions can result in
death, fire. or electrical shock
The air conditioner is powered by plugging it into a

match the plug on the unit power cord See Table 1 for
receptacle types and fuses The unit nameplate con-
tains unit electrical data, unit ratings, and identifica-
tion numbers. The unit nameplate is located on the
mght side of the unit. Do not use a plug adapter or an
extension cord The use of a time-delay fhse or tnne-
delay circuit breaker is recommended
Check available power supply and resolve anb- wiring
problems before installing and operating the air condi-
tioner If wiring is required, all wiring must comply
with all local and national electrical codes All wiring
must be installed by a qualified electrician If you have
an}- questions regarding the unit electrical data or wir-
ing, consult a qualified electrician befbre installation

LOCATION
The room air conditioner is designed to fit easily into a
single or double hung window However, since window
designs val_-, it may be necessary to make some modi-
fications for saf_ and proper installation
Make sure the window and frame are structurally
sound and free from dl'y or rotted wood Replace wood
if necessalT or relocate the air conditioner
For maximum efficiency, install the air conditioner on
the side of the house or building that has more shade
than sunlight
Provide sufficient clearance fbr the air conditioner to
allow proper air circulation through and around the
unit The rear of the unit must be outdoors (not in a
garage or inside of the building) Provide 20-in of
clearance on each side of the unit Provide 20-in of
clearance fgom the rear of the unit to any obstruction
Provide 12dn of clearance from the top of the unit See
Fig 3
Unit should be at least 30dn above the floor and out-
side ground
Cul_ains and other objects should be moved if the)"
block indoor airflow
Unit must be within reach of a proper electrical wail
outlet Do not use an extension cord
The unit was designed to evaporate condensation
under normal conditions Under extreme humidity
conditions, excess condensation may cause the
basepan to overflow to the outside of the unit The unit
should be installed where condensation drip cannot
cause damage
WINDOW INSTALLATION
To install the room air conditioner in a window, per-
form the following procedure
1 Check contents of installation hardware package
provided with air conditioner See Table 2 Make
sure all the items are included
2
3
Determine which window will be used for installa-
tion. See Location section on page _5
Check that the window opening dimensions are
suitable for installation For KC 101P units, the
window must be between 24 andSg-in wide and
the window must open at least 15dn high For
KC 121P units, the window must be between 27
and 41-in wide and the window must open at
least 16-in high It is recommended that the win-
dow sill be at least _/_-in thick to suppol_ the
weight of the air conditioner See Table 3 fbr unit

channel Save remaining seal strip fbr use in
Steps 14 and 22 Peel and stick one side of the
sealing strip on to the top channel (provided) as
shown in Pig 6 Use l/4-in screws (provided) to
attach top channel to cabinet Top channel may
require 4 or 5 screws depending on model See
Fig 7

ing screws (pro_dded) onto the bracket assemblies
See Fig 9
11 Test the bracket assembly in the window See
Fig 10 Adjust the location of the angle brackets if
necessary If location of angle brackets is correct
for installation, tighten bolts on assembly Level-
ing screws should touch the outside wall. If level-
ing screws are too far away from wall it may be
necessary to shim the area with a solid piece of
wood See Fig. 11

STORM WINDOW APPLICATIONS
If the window is blocked by a storm window and the
storm window cannot be removed, a mounting board
(field provided) wiI1 need to be added to the window
sash The air conditioner needs to be pitched down-
ward to the back in order for condensate to drain prop-
erly The fl'ame of the storm window (or any other
obstruction) must be at least 1/2-in lower than the
window sill. If the storm window Dame is not at least
z/2-in below the window sill, then a mounting board
will need to be added to raise the height of the window
DRAIN HOSE

sill See Fig. 19 The board will need to be provided
and cut by the installer
1 The wood mounting board should be a minimum
of 1Ue-in wide and should run the length of the
window The thickness of the mounting board is
dependent on the height of the storm window
frame The mounting board should raise the fl'ont
of the air conditioner high enough so that the unit
will be pitched downward at least _/8-in when the
back of the unit is resting on the storm window
frame See Fig 19

WALL INSTALLATION
To install the room air conditioner in the wall, pe1_orm
the following procedure:
1 Remove air conditioner h'om shipping box Do not
install window installation parts (noted in
Table fi).
2 Determine the location fbr air conditioner Make
sure there is adequate clearance on the inside and
outside of the wall Ensure that the power cord
will reach the available socket withuut an exten-
sion cord An" conditioner can be installed in walls
up to 7 in thick Side louvers must never be
blocked Select a wall surface that:
•does not support major structural loads such as
the frame construction at ends of windows and
under truss-bearing points
•does not have plumbing or wiring routed inside
•is near existing electrical outlets or near where a
new outlet can be installed
•f_ees the area to be cooled and is not blocked by
obstructions
•allows unbloeked airflow fi'om rear (outside) of
installed air conditioner
3 The following parts wilI need to be pro%tided by the
installer:
•wood frame
•wood shims
•wood screws (no 10, 1-in long)
4 Working from the inside of the room. find a wall
stud nearest the center of the area where the air
conditioner will be installed This can be deter-
mined by sounding walls or using a stud finder
5 Cut or knock out a hole on each side of the center
stud See Fig 20
IMPORTANT: Read entire instructions before cut-
ting hole in wall
6Measure between the inside edges of every other
stud as shown in Fig 20
Follow all local building codes when bmlding and
installing frame Build a wooden frame that will
be placed around the unit in the wall The frame
will reinforce the hole in the wall where the air
eonditioner is installed and is used to secure the
air conditioner to the wall The frame should have
an inner dimension of 20 5-in width by 14 8-in
height for 7;3KC 1OlP air conditioners or 22 8-in
width by 15 7-in height for 7;3K0 121P air condi-
tioners to ensure that the air conditioner will fit
inside the frame See Fig 21 The depth of the
frame should approximately match the depth of
the wail The thickness of the h'ame will need to
be added to the dimensions to determine the size
of the hole in the wail
I
IMPORTANT: Be sure to measure air conditioner I
to cheek size before constructing fi'ame I
For example, if using s/4-in thick wood fbr the
fi'ame, the hole would need to be:
I
IMPORTANT: If thickness of the wail covers top I
and side _,_ents of the air conditioner when it is I
installed, the outer portion of the wail opening
clear and uncovered
must be widened The top and side vents must be
8 After the frame has been constructed, check to
make sure that the air eonditioner fits correctly
inside it If the frame is too tight or too loose,
adjust the size or re-construct
9 Measure the outer dimensions of the frame and
use those dimensions to cut the hole in the wall
Make sure the hole is level or condensate will not
drain properly
10 Install wooden h'ame into hole in wail Make sure
frame is properly secured. Fill in the space
between the fi'ame and the studs with wood shims
(spacers) Nails spacers to studs If required, pro-
_dde studs around entire fi'ame to reinforce stabil-
ity of wall See Fig 22
