Evaporative Cooling

Evaporative cooling is nature's way of cooling. When air is moved
over a wet surface, water is evaporated and heat is absorbed. When
stepping out ofa swimming pool with the wind blowing, evaporative
cooling makes you feel cool, even though the air may be warm.
The human body itself is cooled primarily by the evaporation of
perspiration.

This unit works on the same principle. Air is drawn across wet
filter pads where the air is cooledbyevaporation and then circulated
throughout the building. It is this combination of cooled air and the
movement of air over the skin which makes it feel cool.

Unlike refrigeration systems which recirculate the air,an evaporative
cooler continually brings in fresh air while exhausting old air. You
are completely replacing the air every 2 to 4 minutes by opening
windows or doors or a combination of both. The air is always fresh,
not stale, laden:with smoke and odors as happens with refrigerated
air conditioning .

• Pump setting. The rotary switch has 6 settings. The "Pump"
setting will operate the pump without the blower. For best results
turn the switch to "Pump" for a few minutes to wet the pads before

operating the fan.

IF

IF

THEN

It plasters itself to the screen.
OPEN all of the windows one inch and try step 4 again.

It stays on the screen lightly.
PERFECT. You are done. Enjoy your cooler .

• High and low cool settings. The "High Cool" and "Low Cool" set-
tings operate both the pump and the blower. Tum the unit to "Low
Cool" when possible. This lower speed allows the air to stay longer

in the wet pads and therefore increases it's cooling elliciency.

Notes:

• When switching to Low Cool, you must rebalance your home.
Repeat step 4.

• High and low vent settings. The "High Vent" and "Low Vent"
settings operate the blower without the pump. This is useful on
cool nights or at times when just a fan is desired.

• Once you balance your home you can cool some areas more than
others by opening those windows more and closing the others by
the same amount. Repeat step 4 to make sure your home is still air
balanced.

Open Windows To Exhaust Air

An oftcn misunderstood concept of evaporative cooling is the amount
of air that should be exhausted. How much should YOliopcn your
windows'! The fact is that most people do not open their windows
enough. The following method will help you determine the amount
to open your windows.

Champion Air Balancing Method

I. Take a piece of tissue paper and cut it lengthwise into 3 equal

strips.

2. Turn your cooler on High Cool.

3. Open one window at least six inches wide in each room that you
want to cool.

4. Take the piece of tissue paper and put it lip agamst the screen ot
the open window furthest from the cooler discharge opening. Let

go of it. It will do one of three things.

• Check belt tension. A 3 lb. force
should deflect the belt 3/4 inches (see
Fig. 7). Readjust belt if needed.

Spring Start-Up

• Oil bearings. The blower bearings and cooler motor in this unit
should be oiled with a few drops of non-detergent 20/30 weight oil
once each year. The motor docs not need oil if it has no oil lines
for oiling. Motors that have no oil lines are lifetime oiled at the
factory and require no further oiling for the life of the unit.

I;--,CAUTlON:

Do not over oil.
Over oiling can cause motor bum
out, due to excessive oil getting into
motor winding.

• Place window behind retainer strip. Raise back of cooler so that
the window (D-Fig. 2) may be brought down behind top of panel
retainer strip (C-Fig. 2).

• Break fill-in panels to fit. With cooler installed, as described
above, measure for each window fill-in panel and score with sharp
knife and straight edge guide to desired width. To break window
fill-in panels, the panel should be laid over the edge ofa straight flat
surface at the point to be broken off. Apply pressure on the edge
of the panel that extends over the edge of the surface and break off
unwanted piece.

• Install fill-in panels. Place one window 'fill-in panel on each side
of grill and into panel retainer strip at bottom of grill. Place the
other panel retainer strips onto top of neck flange and fill-in panels.
Be sure the panels are snug up against cooler neck.

• Level Cooler. Adjust the chains to level the cooler.

• Adjust house legs. Pull out house legs so that the rubbcr bumpers.
rest against house siding (F-Fig. 2). Tighten screw in retaining
collar. (G-Fig. 2).

• Replace Pads. Aspen pads should be replaced once or twice a
season, depending upon the length of the season. At the beginning
and at mid season a clean pad is more absorbent and efficient and
will deliver substantially more cool air.

• Clean pump. Cleaning the pump is necessary once a year at start-
up. For your safety, tum unit offand unplug from power receptacle .
Remove the pump from the mount slot. Remove the base of the
pump as shown in Fig. 8. Clean the pump and tum the impeller
to ensure free operation. Remove the pump spout and check for
any blockage. After cleaning,
reinstall the base onto the pump.
Press firmly to make sure it is
secure. Reattach the pump to
the mount in the cooler using
the plastic retainer to ensure that
the pump will not overturn. Do
not forget to replace the spout
and water delivery tube onto the Fig. 8
pump outlet.

Winter Shut Down

Drain water. Always drain all of the water out of the cooler and
water supply line when not in use for prolonged periods, and par-
ticularly at the end ofthe season. Keep the water line disconnected
from both the unit and water supply so that it does not freeze.

• Cover unit. To protect the life of the finish, a cover for the unit is
suggested in extended periods of non use.
