INTRODUCTION
Your Brisa 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.
keep insects, dust, dirt, etc out of the cooled space, the house should
be maintained at a slightly positive air pressure (that is, 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 airflow to the areas that are occupied
during different times of the day or night (example: living room
windows during the daytime, bedroom windows at night.)
HINT: To avoid a rush of warm air when starting the cooler be sure to
turn on the pump for a few minutes to completely wet out the pads
before starting the blower.
To get the maximum capacity of your cooler, and to help
Platform or Stand Mounting
Installation normally involves locating the unit in a suitable window
and the construction of a platform or stand to support the weight of the
cooler. Since every installation is different, the exact requirements to
mount and seal a cooler against the weather will be best determined
by the location and at the time of the installation. Most installations will
require blocking of the unused portion of the window around the duct
or other modifications to the window frame may be necessary.
illustration (Fig. 1) for a typical installation. Construct a platform or
stand below the window strong enough to support the weight of the
cooler (approximately 250 pounds).
Measure and construct a level platform or stand that will allow the
bottom surface of the cooler duct to rest on the window sill. Allow
clearance for the drain/overflow standpipe connection.
Position the cooler so that the duct rests on the window sill and the
grille flanges are inside the window frame. DO NOT drive nails or
screws through bottom pan into mounting surface, this will
void the warranty.
Lower the window to rest on the top of the duct (vertically hung
windows) or slide window closed against side of duct (horizontal
slider windows). Block any remaining unused portion of the
window opening with a suitable blocking material (Plexiglas, solid
plastic sheet, solid wood panel, etc.). It will be necessary to seal
any joints around the duct to prevent entry of rain, dust/dirt,
insects, etc. Any good quality caulking or foam tape will work.
See
INSTALLATION
Carefully read the contents of this manual and review the
drawings of the cooler to familiarize yourself with the various
parts before beginning the installation process.
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 cord into the wall
receptacle until installation or service work is complete.
Before attempting to install the cooler, confirm 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 with a qualified
electrician. This receptacle should be located within 5 feet of the
window opening (cooler power cord is 6 feet long. Use of
extension cords is not recommended).
Install cooler in a window 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.
Verify that the supporting surface is strong enough to bear the
weight of the cooler when in use. This unit will weigh
approximately 250 pounds when operating at full capacity.
Verify that the supporting surface is level in all directions.

Mounting Using Chain Kit
An alternate installation method involves locating the unit in a suitable
window and using the included chain mounting kit to support the
weight of the cooler. As with platform or stand mounting, every
installation will be different. The exact requirements to mount and seal
a cooler against the weather will be best determined by the location
and at the time of the installation. Most installations will require
blocking of the unused portion of the window around the duct, or other
modifications to the window frame may be necessary.
illustration (Fig. 2) for a typical installation. Remember, the framing
around the window must be strong enough to support the weight of the
cooler (approximately 250 pounds).
Chain Kit contains:
2 - Screw Hooks 2 - “S” Hooks
2 - Leg Leveling Bolts 2 - Rubber Pads
4 - 3/8” Square Nuts 4 - 3/8” Washers
2 - Hanger Straps 2 - #10-24 x 1/2” long Bolts
2 - #10-24 Nuts 2 - 5 ‘ Long Chain
Install chain kit as follows:
Attach screw hooks to outside window frame approximately two
feet above top of cooler. Be sure hooks are inserted to full depth in
window framing for maximum strength.
Attach chain to each hook.
Attach hanging straps to top of rear corner support legs in the 3/16”
diameter holes using the #10-24 bolts and nuts provided. Install
“S” hooks in straps.
Place leg leveling bolts through 7/16” diameter holes in bottom of
front corner support legs. Use nut and washer on outside of
cabinet and install rubber pads on outside ends of leveling bolts.
Place second nut and washer on leveling bolts inside cabinet.
Position the cooler so that the duct rests on the window sill and the
grille flanges are inside the window frame, allowing the “Z” shaped
bracket, located under the grille, to rest on the window sill and butt
against inside of window sill flange. Connect “S” hooks and screw
hooks to chain links that bring the cooler closest to a level position.
Use leg leveling bolts to brace the cooler away from the wall.
Adjust bolts and chain to level cooler. NOTE: Cooler may need to
be re-leveled to compensate for the added weight of water.
Tighten nuts on leveling bolts inside cabinet.
Lower the window to rest on the top of the duct (vertically hung
windows) or slide window closed against side of duct (horizontal
slider windows). Block any remaining unused portion of the
window opening with a suitable blocking material (Plexiglas, solid
plastic sheet, solid wood panel, etc.). It will be necessary to seal
any joints around the duct to prevent entry of rain, dust/dirt,
insects, etc. Any good quality caulking or foam tape will work.

Install Overflow Standpipe / Drain Line
Install overflow drain bushing in bottom of cooler as follows:
Slide rubber washer over drain bushing.
Push drain bushing through bottom of
cooler, assemble and tighten lock nut.
Screw plastic overflow standpipe into
the drain bushing and tighten snugly
(hand tight) to prevent leakage.
Connect a suitable drain line (copper /
PVC / garden hose) to drain bushing.
Never drain water onto a roof; mineral
build-up or damage to roof may occur.
NOTE: Drain water in accordance with local plumbing codes.
Install Bleed-off
To minimize mineral scale “buildup”use the included bleed-off
assembly. Remove the cap from
the bleed-off tee; insert the black
tubing and route the tubing
through standpipe opening into
the drain line To prevent
siphoning of the water, make sure
h
t at the bleed-off tee is above the
water level.
.
Connect Water Supply
CAUTION: All plumbing installations must comply with
local building and safety codes, and must be performed by
qualified personnel only.
NOTE: Coolers should not be connected to “soft” water systems. Soft
water will accelerate corrosion and decrease the effective life of pads
and cooler cabinet. Connect water line as follows:
A water supply valve should be installed at a convenient location
to allow the water supply to be turned on and off for servicing or
winterizing. Minimum 1/4“ diameter tubing should be used to
provide water to the cooler. Larger tubing is recommended if the
distance from the valve to the cooler is greater than 100 feet, then
reduced to 1/4” at the unit.
Install float valve in the bracket provided.
Connect tubing from water supply to float valve. Place
compression nut and ferrule over end of tubing, insert tube into
float valve then tighten compression nut to secure.
Belt Tension Adjustment
CAUTION: Disconnect all electrical power to the cooler
and insure that belt is not rotating before adjusting belt
tension.
Correct belt tension and alignment is
important, proper setup reduces power
consumption and prolongs life of belt and
motor. Check belt tension by squeezing belt.
Proper tension will allow deflection of ½ to ¾
inch. To increase or decrease belt tension,
loosen bolt in slot of motor support bracket.
Adjust belt to proper tension and retighten bolt.
CAUTION: Never operate unit with
pad frame(s) and/or air outlet grille
removed. This will result in an
overloaded condition and may
damage the motor.

Regular maintenance and periodic inspection is the key to long and
successful service from your Brisa cooler. The cooler should receive
major servicing at least once a year, more often if conditions require
(dusty environment, constant use, poor water quality, etc.) For
maximum cooling efficiency, long 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 finished with our Peblar XT®
appliance-type finish. It is so hard that asphalt-type cooler water pan
under-coatings will not stick to it. Undercoating will break free,
clogging the pump and water distribution system.
NOTE: Do not use cooler cleaners, cooler treatments, anodes or other
chemical additives in this evaporative cooler. Use of any additives or
water treatment other than the furnished bleed-off will void your
warranty and may impair the life of the cooler.
Before starting any maintenance operation, thoroughly read all
operating and maintenance instructions and observe all
cautions and warnings.
Cleaning
CAUTION: Never wash your cooler cabinet with a
garden hose; water may harm motor and pump or seep
into ductwork. Motors damaged by water are NOT covered
under warranty.
All foreign materials, mineral scale, hard water deposits, dirt, etc.
should be removed from pad frames, water pan and other
components. Your cooler's long lasting finish can be brought to likenew condition by using warm water and a soft cloth.
NOTE: Avoid using scouring pads, steel wool or wire brushes, as
these will damage the finish and encourage corrosion.
Maintenance & Inspection
IMPORTANT: Before operating cooler at the beginning
of each cooling season, turn blower wheel, 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 efficiency, every two months
during operation, or any time the cooler is opened, the cooler should
be inspected. Some suggested items to look for:
P Check for leaks from pad frames, cabinet, etc.
P Any dry spots or streaks on pads when pump is operating?
P Are bolts, nuts and set screws still snug?
P Are the bearings, etc., making any unusual noises?
P Does the blower wheel turn freely?
P Is float level set correctly?
P Is water in the bottom pan clean?
P Belt condition / tension / alignment OK?
Adjust Belt Tension
Each time you inspect your cooler, be sure to check belt tension on
motor and blower assembly. Check belt condition and replace it if
frays or cracks appear. Check alignment of blower pulley with motor
pulley (see page 3 for detailed steps).

Cleaning Water Pump & Hose
CAUTION: Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler.
CAUTION: Do not allow pump to fall over and become
submerged; water will damage pump motor.
Clean water pump and hose assembly as follows:
Unplug pump cord, remove
mounting bracket screw and
remove pump from cooler. Shake
gently to remove water.
To prevent breakage, carefully
release the snap-out impeller
cover plate and remove cover
plate from the pump body.
Using a mild detergent solution and a
soft cloth, clean deposits from screen,
around impeller and cover plate. Spin
impeller to dislodge any remaining
foreign material.
Remove any foreign material in the hose adapter
(between the pump and hose), or between the hose
and the water distributor assembly.
Rinse and reinstall impeller cover plate.
Reinstall pump and reconnect pump cord.
Draining
Drain the cooler for cleaning or at the end of the season as follows:
Unplug cooler power supply cord from wall receptacle.
Turn off water supply and remove pad frames.
Connect a drain hose to the drain fitting on the bottom of the
reservoir, if not already connected to drain line.
Remove overflow standpipe from the drain fitting.
Drain and clean reservoir. Remove any remaining water with
a rag or sponge.
Touch-Up
The hardness, adhesion and smoothness of the internal and external
finish on your cooler makes it extremely unlikely that scratches or
chipping will occur. In the event that finish 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.
Blower Shaft Bearings
Blower shaft bearings need periodic lubrication. They should be
checked 20-30 days after initial start-up of operation. The oil cups on
the bearings should be filled with a good grade of SAE 20W or 30W
non-detergent oil when necessary. Under normal use, oiling is
required every three months of operation. Do Not Over- Oil.
Pump Motor Bearings
The pump motor does not require lubrication.
Changing Cooler Pads
CAUTION: Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler.
Your cooler pads should be changed at least twice a year… at the
beginning of and midway through a season . However, your pads may
need to be changed more frequently, depending on local air and water
conditions. For instance, in areas where mineral content of the water
is high, deposits may build up in the cooler pads, restricting airflow.
Replace pads as follows:
Remove pad assembly from cabinet.
Remove pad retainers from frame, using caution as retainers can
spring back. Carefully remove all aspen from retainers. Remove
and discard old pads.
Using a mild detergent, wash dirt and scale from pad frames and
rinse with fresh water. Wire brushing is not recommended. If finish
is damaged or rusting is noted, repair area as noted in the “TouchUp” section.
Lay new pad in frame, starting at trough end, making sure pad is
snug against trough and outer edges with no air spaces. Pad must
completely fill frame (no gaps) or hot air may enter building.
Pad thickness should be
uniform across the frame.
Replace pad retainers and
lock under edge of frame.
Sharp points must be buried
into pad (they hold pad in
place and prevent sagging).
Pre-soak pads and check for air gaps along
edges, reinstall pad frames into unit.
Winter Shut Down:
- Always drain all of the water out of the cooler and water supply line
when not in use for prolonged periods, and particularly at the end of
the season. Keep the water line disconnected from both the cooler
and the water supply so it does not freeze.
- Disconnect power from cooler during extended periods of non-use.
Lubrication
Motor Bearings
Some motors used in Brisa coolers have ports for lubricating the
motor and are oiled at the factory. If the need for oiling is indicated, see
individual motor nameplate for specific instructions on re-lubricating
the motor. Under normal use, these motors require oiling about every
12 months of operation. Do Not Over-Oil.
REPLACEMENT PARTS
When ordering replacement parts, always refer to the serial and
model number of your cooler. Use the part numbers listed in the
accompanying parts list, as illustrated in the diagrams for your model.
