The serial number isunique to each product.It is required to be paid

for warranty service andto get the correct part inthe event a runningproduction change wasmade.

Some models may havefour (4) letters instead oftwo (2) for the product

code number. The thirdand fourth letters aresignificant only to themanufacturing facility.

For temperature

readings,

DB = dry bulb and

WB = wet bulb.

There are types of

thermometers used in

conjunction with

hygrometers indetermining actual and

absolute temperature

and humidity readings.

Specifications


4/91

The LWHD1006R is a 115-volt window air conditioner. This product is a

consumer comfort appliance, not a precision climate control system.

p6LWHD1006R

Introduction


5/91

The power cord is equipped with a 3-prong grounding plug. It also

incorporates an AFCI (Arc Fault Current Interrupter) as an integral part of

the power cord. If the TEST button does not trip or the RESET button does

not restore power, unplug the air conditioner and call an Authorized

Service Technician.

DO NOT tamper with or attempt to defeat or repair this device.

A faulty socket or bad connection can cause this device to trip.

Grounding


6/91

The model and serial numbers are

on a sticker on the right side of the cabinet as you face the air conditionerinside the house.

p7

These are always visible

if the air conditioner isinstalled correctly.

Product Identification


7/91

There is another sticker on the left side showing other importantinformation about the air conditioner, including refrigerant type and charge.

p7LWHD1006R

Product Identification


8/91

This air conditioner is designed to operate with approximately of water

in the base pan. The condenser (outdoor) fan is made with a ring around

the edge of the blades. This slinger fan runs in the condensate collected in

the pan and expels it through the condenser, which causes a slightincrease in efficiency.

There is no need to add water if the pan is dry.

p9LWHD1006R

Maintenance


9/91

The air conditioner is designed to be installed in a double- or single-hung

window with an actual opening width of 25 ~ 36 inches (not through a hole

in a wall or other structural modification) and plugged into a single-outlet,

dedicated 15-amp circuit without using an extension cord.

All applicable clearances

should be maintained.

All side louvers on the

cabinet must remain exposed

on the outside of the structure.

p9LWHD1006R

Installation


10/91

Abbreviated installation instructions are included in the event the installer

must remove the air conditioner or replace it in the window.

p10LWHD1006R

Installation


11/91

TitlesBe sure the air conditioner is installed securely and firmly.

Install the air conditioner so the back (outside) is slightly lower than the

front. This will force water to the drain at the back of the base pan.

Install the air conditioner

so it is between

30 and 60 inches

above the floor.

p10LWHD1006R

Installation


12/91

If excess water collects in the base pan or the fan makes undesirable

noise running in the water, remove the rubber plug and install the drainpipe.

You can connect a hose

to the pipe and route

the overflow to a

convenient drain place.

p10

Dimensions


15/91

The installation kit includes all the parts necessary to install the airconditioner. The panels (1) are different for the left and right sides.

Refer to the chart to identify parts .

Kit is Part # 3127A10015B.

p11LWHD1006R

Installation


16/91

Refer to the parts list to ensure all parts are included.

Sort the screws by size, shape, and quantity to determine which is which.The foam strip

(PE = poly-ethylene)

with adhesive is to be

applied under the

upper guide before

it is attached to the cabinet.

p10LWHD1006R

Installation


17/91

Remove the screws at theback and the sides

of the cabinet.

Grip the base pan handle

at the front and pull the

chassis out while holding

the cabinet.

Remove the packingmaterial taped to the

dryer inside the air

conditioner and discard it.

p10LWHD1006R

Installation


18/91

Attach the adhesive foam strip (11) tothe bottom of the upper guide (10).

p12LWHD1006R

Installation


19/91

p12

Attach the upper guide (10) to

the cabinet using three screws(Type A).

Note that the screws are inserted

into the guide from inside the

cabinet into the upper guide,

not through the guide into the

cabinet on the top.

LWHD1006R

Installation


20/91

Insert the frame guides in the

bottom of the cabinet. Place

the rounded part in the

center track and the tabs into

the rectangular slots. Press

the clip down toward the front

of the cabinet until the tabsclick into place.

p12LWHD1006R

Installation


21/91

Insert the frame

curtains into upper andlower guides, then

attach them with 4

screws (Type A) oneach side.

A long driver works best.

p12LWHD1006R

Installation


22/91

Open the window.

Mark the centerline on the sill.

Place the cabinet in the

window and align it with the

centerline.

Attach the cabinet to the sill

with wood screws (Type B).

Lower the window to allow thesash to fall behind the upper

guide so the cabinet can rest

against it.

p13LWHD1006R

Installation


23/91

Thread the nut onto the bolt andthread the bolt into the sill support.

(Do this for both sides.) Use this

bolt to adjust the cabinet height so

it hangs out of the window withthe back (outside) slightly lowerthan the front (inside).

p13LWHD1006R

Installation


24/91

Use 2 screws to attach thesill support to the bottom

of the cabinet from the

inside. You may have to

slide it forward or back toget it in the correct place.

p13LWHD1006R

Installation


25/91

Attach the cabinet to

the window sill by

driving 3 Type B screws

through the front angle

of the cabinet into thewindow sill.

p13LWHD1006R

Installation


26/91

Attach the frame

curtains to the window

sash (top) and track

(bottom) using Type Cscrews.

p13LWHD1006R

Installation


27/91

Slide the chassis into the cabinet.

Reinstall the Type A screws in the

sides and back of the cabinet.

Place the foam strip in the gap

between the inner and outerwindows to keep drafts and

vermin out.

p14LWHD1006R

Installation


28/91

Attach the window

locking bracket using a

Type C screw. This

secures the window to

keep the air conditionerfrom falling out andburglars from getting in.

p14LWHD1006R

Installation


29/91

Attach the front grille by placing

the top on the cabinet and

engaging the tabs on the grille

in the slots on the cabinet.

Push the grille down until it

snaps into place.
