I CAUTION
To avoid risk of personal injury,property damage, or product damage due to weight of air conditioner and sharp
edges that may be exposed:
- Air conditioners covered in this manual pose excessive weight hazard. Two or more people are needed to
move and install air conditioner.Toprevent injuryor strain, use proper liftingand carrying techniques when
moving air conditioner.
• Carefully inspect location where air conditioner will be installed. Be sure itwill support the weight of air
conditioner for extended period of time.
• Handle air conditioner with care. Wear protective gloves whenever lifting or carrying air conditioner. AVOID

Sizing Instructions
Many complaints about room air conditioners result
from units that are over-sized or under-sized for a given
area. Over-sized units cool an area before humidity can
be adequately removed, so air feels cold and clammy.
Under-sized units do not sufficiently cool an area.
The following table contains guidelines for properly
sizing a room air conditioner for a given area.
To size unit:
1. Determine size (in square feet) of area to be cooled;
locate square footage in far left column of table
below.
Required Air Conditioner Cooling Capacity--Btu/hour

to be Cooled

2.
Choose right-hand column showing location of room
inbuilding:
• Room below attic; insulated ceiling above.
• Room with occupied room above.
• Top floor under insulated roof.
3,
Follow down right-hand column, reading horizontally
from square footage to lind approximate air
conditioner capacity (in Btus per hour) required to
adequately cool designated area.
NOTE: When determining size of unit, also consider
conditions at bottom of table. For best results,
choose air conditioner with cooling capacity
(Btus per hour) closest to, but not exceeding,
estimated size.

• If normal occupancy of area is more than two people, add 600 Btu/hour per person. If normal occupancy is one
person, subtract 600 Btu/hour.
• Add 1200 Btu/hour if area includes a kitchen,
• If room isheavily shaded, subtract 10 percent from total capacity. Increase by 10 percent ifarea is very sunny.
Installation
Installing Room Air Conditioners
Proper installation of a room air conditioner helps
ensure trouble-free operation, improper installationcan
result in problems ranging from excessive noiseto
property or equipment damage.
Installation requires some mechanical experience and
aptitude. Depending upon installer's knowledge and
skill, installation of a room air conditioner can take
between 1 and 3 hours. Professional installation,
performed by authorized Sears technicians, is available.
Contact a local Seers store or call 1-800-4-MY-HOME to
obtain an estimate and schedule an installation.
Before Beginning Any Installation
• Carefully read all installation instructions. Make sure
each step or procedure is understood and any special
considerations are taken into account.
- Before starting installation, assemble all tools,
hardware, and supplies needed• Some items may
need to be purchased locally.
• After deciding where to install unit, carefully examine
Iocation_both insideand outside. Note any potential
obstacles or problems. Choose a more suitable
location, ifnecessary.
Electrical Requirements
Grounding Instructions
For safety, air conditioner must be grounded. All air
conditioners have power supply cord with three-prong
grounding plug. To minimize possible electrical shock
hazard, power cord must only be plugged into matching
groundingwall receptacle in accordance with National
Electrical Code (and any applicable localcodes and
ordinances). If appropriate grounding-type wall
receptacle isnot available, have properly groundedwall
receptacle installed by qualified electrician.
If codes permit and separate grounding wire is used,
have qualified electrician determine ifgrounding path is
adequate and uninterrupted by plastic, non-metallic
gaskets, or other insulating (non-conductive) materials.
Electrical Connection
A separate (dedicated) circuit is required for units
labeled "Use on Single Outlet Circuit Only." Devices
covered inthis manual require a 60Hz supply. Refer to
unitnameplate for exact voltage requirements. Voltage
requirements can also be determined by type of plug on
air conditioner. See Table 1.

I WARNING
To avoid dsk of personal injuryor death due to
electrical shock:
• DO NOT remove warning tag from power cord•
• Electrical grounding is required on all air
conditioners.
• Check with a qualified electrician if you are not
sure intended electrical outlet is properly
grounded.
• DO NOT ground to gas line.
• DO NOT ground to cold water pipe if pipe is
interrupted by plastic, non-metallic gaskets, or
other insulating (non-conducting) materials.
• DO NOT modify plug on power cord. If plug does
not fit electrical outlet, have a matching outlet
installed by a qualified electrician.
• DO NOT have a fuse in the neutral or ground
circuit. A fuse in the neutral or ground circuit
could result in an electrical shock.
• DO NOT use an extension cord with this device.

preceding page. Minimum size of wiring, based on
power requirements, is:
Units up to 20 amps: 12 gauge
20-30 amp units: 10 gauge
Use copper wire only. It is owner's responsibilityto
provide proper and adequate receptacle wiring that
conforms to all applicable codes. All wiring should be
