EVAPORATIVE COOLER

AZ Air Coolers LLC
ASSEMBLY INSTRUCTIONS
Coolers are pre-assembled and ready to operate. Simply remove the
packaging and then carefully remove the unit from the box.
Install the casters. Lock the 2 locking wheels before filling and turning on
fan to keep the cooler from moving from the air velocity.
NOTE:
The media pad will have a slight odor when it is new. This is
normal. It will dissipate after a period of time depending on the use time.
Draining the tank often during the break in period will help speed this up.
OPERATING INSTRUCTIONS
1. Your cooler must be positioned in front of an open window or door if it
is to operate effectively.
2. Always ensure that there is another open window or door through
which the air can exhaust from the room.
3. Ensure the filter is kept clean throughout the summer season.
4. At the end of each day run your cooler on FAN ONLY for 30 minutes to
dry out the filter.
5. Prior to putting your cooler away for winter, always:
a. Drain the tank and wipe out clean.
b. Clean the filter.
c. Re-assemble and run on FAN ONLY for 30 minutes to dry out the filter.
6. Having completed assembly of your cooler, position the unit with
its back to an open window or door. This will allow fresh air to be
drawn through the cooler and exhausted from the room. Constant
air change is essential and part of the fresh air benefit from
evaporative air cooling.
7. Remember your cooler has been designed to operate even if it runs
out of water. No damage will be caused to the pump if cooler runs out
of water.
FILLING COOLER OR CONNECTING TO WATER SUPPLY
Move the cooler to an area where it can be filled.
MANUAL FILL
The cooler can be filled via the front fill door by hose or bucket. Using the
water fill indicator to monitor water level, simply depress the fill door and the
spring lock will release and open it. To close, simply push it closed and locked.
AUTO FILL CONNECTIONS
Connect to a water supply using a garden hose or coil hose (supplied
by customer), or a direct water line. (Parts for direct connection can be
obtained at any hardware store.) Simply attach hose adapter (supplied
with cooler) to the float valve nipple protruding from cooler. Verify water
tight connections by visually examining the hose connection.
CAUTION
Water inlet pressure should be limited to a maximum 50 PSI. If valve is
overcome, install a pressure reducer (25 PSI) on nipple first. (It can be
obtained at hardware stores in irrigation section.) Hose bib needs only be
cracked open slightly to supply water to float valve and the cooler only
needs to be about half filled when in auto fill configuration. The float is
already set to that level.
USING THE CONTROL SWITCHES MECHANICAL VERSION
ROTARY SWITCH/MOTOR SPEED
4 POSITIONS: (CLOCKWISE FROM OFF)
0. Off
2. Medium fan
1. Low fan
3. High fan
Left rocker switch:
Controls water pump on or off.
Middle rocker switch:
Controls fan oscillation.
POWER SWITCH
Controls power to the main controls, it will be lit when it is in the ON position,
dark when OFF. When it is OFF the other switches will not function.
NOTE:
The pump circuit is equipped with an encapsulated pump cut-off
float switch mounted in the cooler. If the cooler is low on water, the water
pump will not operate and the pump switch will be interrupted.
MAINTENANCE
WARNING
: Do not remove the back panel with the cooler running.
NOTE:
For best operation and long useful life the following maintenance
and cleaning procedures should be followed.
CLEANING COOLER AND PADS
At regular intervals the cooler should be shut down and disconnected
from power supply. The water tank should be drained of dirty water and
sprayed out with fresh water and refilled. The more you do this the better
it will work and less calcium will develop on pads or other surfaces.
You may spray through the cooling pads to wash them out and allow
water to deposit in the tank to be drained away. The removable panel
and media pad can be sprayed out on the ground to clean pad. Use light
pressure when spraying pads. NEVER spray pads with water while cooler
is operating and fan is running. This can cause damage to motor and will
void the warranty.
REMOVAL OF THE BACK PANEL
WARNING
: Disconnect power supply before this procedure.
1. Unscrew the screws at top of back panel (3).
2. Lift Panel up and pull out at the bottom.
3. Slide the panel out of the cabinet.
4. You will now have access to the pump, float valve and the water
distributer spreaders.
DRAINING THE COOLER TANK
Unscrew drain cap from drain assemble and drain away water. You may tip the
unit carefully to the drain side to help drain all the water out.
REMOVAL AND REPLACEMENT OF COOLING MEDIA
The cooling pads are made from a special resin impregnated craft paper
specially designed for evaporative cooling. They will last many years if
maintained properly and water quality is maintained. It is not necessary to
remove the pads to clean them.
Inspect the pads for deposits of calcium on the air entering side. If the flute
cells are clogged or the pad is very heavy it may be time to change the media.
New media can be purchased where you bought the cooler. Follow these steps
for replacing the pads.
