INTRODUCTION
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 (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.)
To get the maximum capacity of your cooler, and to help
INSTALLATION
Carefully read the contents of this manual and review the
drawings of the cooler (Fig. 1 & 2) 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.
Mounting the Cooler
Installation normally involves locating the unit in a suitable window
and using the included chain mounting kit or 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
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.
Chain mounting:
Remove pad frame from cooler.
Position the cooler so that the duct rests on the window sill and the
grille angle flanges are inside the window opening. Using a
adjustable wrench, adjust the legs firmly against the wall to level
the cooler and to hold it in place.
Attach the 2 screw hooks to the top of the outside window frame.
Attach one end of each chain onto each hook.
Insert “S” hooks into holes in the top rear corner of the cabinet,
using the hooks to pierce the vinyl hole cover (2 places).
Connect the “S” hooks to the chain so the cooler is level.
Shelf or stand mounting:
Construct a platform or stand below the window, strong enough
to support the weight of the cooler (approximately 100 pounds).
Make the platform or stand mounting surface so that the height is
11 5/8” below the resting point of the cooler duct on the window sill.
Remove pad frame assembly from cooler.
Position the cooler so that the duct rests on the window sill and the
grille flanges are inside the window frame. Using a adjustable
wrench, adjust the legs firmly against the wall to hold cooler in
place. 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
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
100 pounds when operating at full capacity.
Verify that the supporting surface is level in all directions.

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 the
pad and the 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 cabinet as shown in Figure 3.
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.
Turn on water supply and check for leaks. Adjust float to maintain
the water level at 2” to 2 ½”.
Install Bleed-off (Model WH2906)
To minimize mineral scale “build-up”,
use the included bleed-off assembly.
Remove the cap from the bleed-off tee;
insert the 1/4” diameter black tubing
and route the tubing through the 7/16”
hole in the side of the cooler opposite of
the float valve. Run bleed-off tubing to a
proper drain To prevent siphoning of
the water, make sure t at the bleed-off
tee is above the water level.
NOTE: Drain water in accordance with local plumbing codes.
.
h
Install fitting for drain pump (HE2913)
To minimize mineral scale “build-up”, these window cooler models
include an automatically timed drain pump for removing mineral laden
water from the cooler pan. It is factory set to operate every 8 hours of
unit operation in the “COOL” mode and will run for 5 minutes. Install
the drain bushing for the auto-dump drain pump discharge hose in the
side of the cooler as follows: (See figure 4)
Locate drain hose assembly in bottom of cooler and remove lock
nut from drain bushing (leave rubber washer in place). Check that
the opposite end of the hose is still connected to the drain pump.
Push drain bushing through hole in side of cooler (opposite of float
valve), rotate hose until anti-siphon fitting tube is pointing toward
bottom of cooler, then assemble and tighten lock nut.
Connect a suitable drain line (garden hose, etc) to the drain
bushing. Never drain water onto a sidewalk or other hard surfaced
area; mineral build-up or a slipping hazard may occur.

MAINTENANCE SCHEDULE
Cleaning Water Pump & Hose
Regular maintenance and periodic inspection is the key to long and
successful service from your 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
inside the house through the window duct. Motors
damaged by water are NOT covered under warranty.
All foreign materials, mineral scale, hard water deposits, dirt, etc.
should be removed from pad frame, water pan and other components.
Your cooler's long lasting finish 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 finish and encourage corrosion.
Maintenance & Inspection
IMPORTANT: Before operating cooler at the beginning
of each cooling season, turn blower wheel and pump
motor shaft by hand to make sure they turn freely. Failure
to do so may result in burning out motor.
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 the bearings, etc., making any unusual noises?
P Does the blower wheel turn freely?
P Is float level set correctly?
Draining
Drain the cooler for cleaning or at the end of the season as follows:
Push “COOL” and “FAN” switches to the “OFF” position. Turn off
water supply to cooler.
Remove the pad frame assembly and disconnect the pump hose
from the water distributor (located at the inside top of the cooler.
Place end of hose outside of unit for draining, keeping in mind the
amount of water to be discharged.
Turn cooler pump on by pushing “COOL” switch to the “ON”
position, pumping water out of cooler pan. Switch pump “OFF”
when no more water can be pumped out. Unplug cooler power
supply cord from wall receptacle.
Remove any remaining water with a sponge or rag.
Replace pump hose on water distributor, reinstall pad frame
assembly into cooler.
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 power supply cord from
wall receptacle, remove pump
mounting bracket screw and
gently lift 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 power cord.
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.
Lubrication
Blower Motor and Pump Motor Bearings
The blower and pump motor bearings do not require lubrication.
Grille Cover
Model HE2913 is supplied with a grille cover. This cover is used
during periods of non-use or for winterizing your cooler.
Flexible tabs on each side hold the cover in place over grille. Pull side
tabs out and forward to install or to remove cover from grille.
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.
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 diagram for your model.
