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

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.

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
