INTRODUCTION

Your Slim Wall evaporative air cooler was thoroughly tested

and inspected before leaving the factory. This manual is

your guide to proper installation procedures along with

information about reasonable care and maintenance that will

ensure safe, economical and trouble free cooling. Failure to

follow these instructions may damage your cooler, impair

its operation, create the potential for serious personal injury

and/or void the warranty.

Read it carefully.

A Note About Air Exhausting/Maximum Cooling

Since coolers function best when there are plenty of

openings for the air to exhaust, you can leave doors or

windows open so your house can breathe. To get the

maximum capacity of your cooler, and to help keep insects,

dust, dirt, etc. out of the cooled space, the house should

maintain a slightly positive air pressure (there should be

slightly more air going into the house than is leaving). This is

controlled by how much the windows or doors are opened.

How much should you open your windows or doors? You

should adjust your openings until the air pressure inside

the house is nearly balanced with the air outside. A good

method to determine when the air is reasonably balanced is

to place a tissue paper against the screen in the window or

door farthest from the cooler and adjust the other openings

in the house until the tissue paper stays lightly on the

screen. You can adjust different windows in the house to

direct the most airow to the areas that are occupied during

different parts of the day or night (example: living room

windows during the day and bedroom windows at night.)

Carefully read the contents of the manual and review the

drawings of the cooler to familiarize yourself with the

various parts before beginning the installation process.

Do NOT attempt to perform any part of the installation

described in this owner's manual unless you are fully

qualied to do so.

CAUTION: Disconnect all electrical power to the

cooler before attempting to install, open or service your

cooler.

Even while routinely inspecting or servicing the inside, the

cooler can be accidentally started. Keep people and pets

away from the cooler and electrical supply when you are

working on it. Before opening, servicing or cleaning the unit,

unplug the unit from the wall receptacle and take steps to

ensure that the cord cannot be plugged back in and the

cooler turned on accidentally. Do not plug power cable into

receptacle until installation or service work is complete.

Before attempting to install the cooler, conrm that the

following preparations have been made:

• This cooler must be plugged into a 120 volt GFCI (Ground

Fault Circuit Interrupter) protected receptacle. If you are

not sure that the receptacle is GFCI protected, consult

INSTALLATION

• Install cooler where only fresh outside air can enter.

Avoid installing the cooler in an area where the free

air movement around and into the cooler is restricted

or locations where obnoxious odors or fumes may be

drawn into cooler from vent pipes, kitchen exhausts, etc.

• Proper installation requires a wall with a thickness

between 6" and 8-½". If the wall is thinner than this a

spacer can be installed on the outside of the wall to

properly space the unit.

• It is extremely important to create a watertight seal

between the outside wall and the duct passing through

the wall.

2. Locate wall studs

NOTE: This cooler is intended to be installed between

studs that are either 16" on center or 24" on center.

The unit cannot be installed between studs that are

less than 16" on center. If studs are less than 16" on

center a different installation location must be chosen

or structural changes must be made. Consult a qualied

professional before making structural changes to the

wall.

CAUTION: When cutting or drilling into the wall,

do NOT damage electrical wiring or other hidden

utilities (water or gas lines, sewer lines, etc.).

3. Once you have selected the studs you intend to use,

mark the lines for the duct cutout.

Use a level and mark a horizontal line a minimum of

24" off the ground. Add a second horizontal line 14-¾"

above the rst line. Mark two vertical lines 13-½" apart

to form a rectangle that is centered between the studs

that were selected for installation.

4. Ensure that the lines are in the correct places and

then cut through the entire wall including the drywall.

5. Measure the thickness of the wall.

If the thickness is less than 6", a spacer will be required

as specied in step 6. If the thickness is greater than

6", skip step 6 and proceed to step 7.

1st - Lift

panel up

2nd - Pull

6. If a spacer is required, make one from wood that is a

minimum of 1-½" wide similar to what is shown (Fig.5).

Ensure the thickness of spacer combined with the wall

thickness will be between 6" and 8-½". Cut boards to

t around the duct cutout. Cut two 26" long boards to

make spacers for the mounting brackets. Space the

lower spacer so the center of the board is 17-¼" below

the bottom of the cutout. Ensure that the spacer is level

and that the fasteners used will not interfere with the

fasteners that will be used to connect the bracket to the

spacer. Place the top spacer so the center of the spacer

is 35" from the center of the lower board.

7. Attach the angle brackets to the studs. Place the lower

bracket ange up so that the top of the ange is 16-1/8"

below the bottom of the duct cutout. Ensure the bracket

is installed level and is centered in relation to the duct

cutout. Pre drill the holes and attach the brackets using

the included lag screws. Attach the top bracket with the

ange facing down at a vertical distance of 33" from the

ange of the bottom bracket. Ensure the bracket is level

and centered in relation to the duct cutout.

or annual start-up, the following procedure should be

followed.

• Open building exhaust/ relief vents (windows, doors,

etc.)

• Plug supply cord into receptacle.

• Push “COOL” switch to ON position (pump on).

• Verify that pump starts and pads are evenly wet.

• Switch “FAN” to “HIGH”, observe that the motor starts

and runs.

• Switch to “LOW”, observe that the motor changes to low

speed.

In case of trouble in any of these stages, refer to the

Troubleshooting chart on page 8.

After initial start-up and during periodic inspections,

check for and/or observe the following: Refer to the

Troubleshooting Chart on page 8 if necessary.

• Leaks from cabinet.

• Observe cooler media for uneven wetting

• Conrm water level setting is correct.

• Verify full, even ow in water distribution system.

• Blower wheel rotates freely, no unusual noises.

• Check motor mounting, cabinet hardware and setscrews

on blower wheel are tight.

CABINET INSPECTION

CHECKLIST

Controls

Rocker-type control switches are used to select the

operating mode of the cooler. These switches control fan

speed (FAN-HIGH/OFF/LOW) and the pump operation

(COOL-ON/OFF). To eliminate a rush of warm air when

starting the cooler, be sure to turn the pump (COOL) on for

a few minutes before turning on the blower motor (FAN) in

low or high speed.

OPERATING INSTRUCTIONS

Regular maintenance and periodic inspection is a key to

long and successful service of your Slim Wall Cooler. The

cooler should be serviced at least once a year or more

often if required (dusty environment, constant use, poor

water quality, etc.). For maximum efciency, longer life

and appearance, every two months during operation, the

cooler should be inspected and cleaned.

Note: Do NOT undercoat the water reservoir

Your cooler's water reservoir is nished with our Peblar

XT® appliance-type nish. It is so hard that asphalt-type

cooler undercoating will not stick to it. Undercoating will

break free, clogging the pump and water distributor.

MAINTENANCE SCHEDULE

Page 6

NOTE: Do NOT use cooler cleaners, cooler treatments or

other chemical additives in this evaporative cooler. Use of

any additives or water treatment will void your warranty

and impair the life of the cooler.

Before starting any maintenance operation, read

thoroughly all operating and maintenance instructions and

observe all CAUTIONS and WARNINGS.

CAUTION: Never wash your cooler cabinet with

a garden hose; water may harm motor and pump.

Motors damaged by water are NOT covered under

warranty.

All foreign materials, scale, salt deposits, lime, etc. can

and should be removed from bottom pan and other

components. Your cooler's long lasting nish can be

brought to like-new condition by using warm water and a

soft cloth.

NOTE: Avoid using scouring pads, steel wool or wire

brushes, as these will damage the nish and encourage

CLEANING

CAUTION: Disconnect all electrical power to the

cooler by removing the plug from the receptacle before

attempting to install, open, or service your cooler.

IMPORTANT: Before operating cooler at beginning

of each cooling season, turn cooler motor and pump

motor shafts by hand to make sure they turn freely.

Failure to do so may result in burning out motor.

Periodic inspection of your cooler will enhance the chance

for long, trouble-free service life. For maximum efciency,

every two months during operation, or any time the

cooler is opened, the cooler should be inspected. Some

suggested items:

• Check for leaks

• Are there any dry spots on the media when cooler is in

operation?

• Are bolts, nuts and set screws snug?

• Are the bearings, etc. making unusual noises?

• Does the blower wheel turn freely?

• Is oat level set correctly?

• Is water in the bottom pan clean?

MAINTENANCE & INSPECTION

CAUTION: Do not allow pump to fall over and

become submerged; water will damage pump motor.

Clean water pump and hose assembly as follows:

1. Unplug power supply cord from wall receptacle, remove

pump mounting bracket screw and gently lift pump

from cooler. Shake gently to remove water.

2. To prevent breakage, carefully release the snap-out

impeller cover plate and remove cover plate from the

pump body.

3. Using a mild detergent solution and a soft cloth, clean

deposits from screen and around impeller to dislodge

any remaining foreign material.

4. Remove any foreign material in the hose adapter

(between the pump and hose), or between the hose and

water distributor assembly.

5. Rinse and reinstall impeller cover plate.

6. Reinstall pump and reconnect power cord.

CLEANING WATER PUMP

& HOSE

The hardness, adhesion and smoothness of the internal

and external nish on your cooler makes it extremely

unlikely that scratches or chipping will occur. In the event

that nish damage does occur, it

should be promptly repaired by the following procedures:

1. Sand the area around bare metal spots.

2. Prime and paint with a quality paint.

Do NOT use asphalt type cooler undercoat material in

water reservoir. Undercoat will break free, clogging the

pump and water distributor.

TOUCH-UP

Blower Motor and Pump Motor Bearings

The blower and pump motor bearings do not require

lubrication.

Cleaning or Replacing Media Pads

CAUTION: Disconnect all electrical power to the

cooler before attempting to install, open, or service

your cooler.

The condition of your cooler pads should be checked

at least once a year; at the beginning of the season is

best. However, your pads may need to be checked more

frequently, depending on local air and water conditions.

For instance, in areas where mineral content of the water

is high or the air is dusty, deposits may build up in the

cooler pads, restricting airow.

LUBRICATION

Page 7

Clean or replace pads as follows:

1. Disconnect power from unit.

2. Remove pads from cabinet as follows:

a. Remove back panel from cabinet.

b. Remove pads by sliding the pad straight backwards.

3. If passages are clogged or pad is dirty, hose off inlet

face of pad. Light, gentle brushing of the inlet edges

of the pad with a stiff bristle brush (do not use a wire

brush) will not harm the pad and will remove more

stubborn scaling.

4. If necessary, replace with new rigid media pads,

available only from your rigid media dealer. Aspen,

expanded paper or other types of evaporative cooling

pads will not work and will void your warranty.

5. Using a mild detergent, wash dirt and scale from the

inside of the wet section cabinet. Wire brushing is not

recommended. If nish is damaged or rusting is noted,

repair as noted in the “Touch-Up” section. Rinse with

fresh water.

6. Reinstall pads, making sure they are positioned

correctly

7. Reinstall back panel
