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 of a 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
fi lter pads where the air is cooled by evaporation 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.

Safety Rules

1. Read these instructions carefully.

2. Unit must be in the Off Position and Unplugged from power

receptacle when installing or performing any maintenance.

3. This cooler will run on 120 volt A.C., 60 Hz (cycle) current
only.

4. Motor and pump are grounded and have an automatic thermal
overload switch which will shut motor off if it overheats. The
motor will restart automatically when it cools down.

5. Pump receptacle is for grounded evaporative cooler pump only.
Do not plug anything else into receptacle.

WARNING: T o reduce the risk of fi re or electric shock, do not

use this fan with any “solid-state fan speed control device.”

Operation

Manual Control Units

• 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.

Exhaust Air

If the unit is used in an enclosed area, open windows or doors to
ensure adequate exhaust. Without an outlet to exhaust the air,
humidity will build up in the enclosed space and the unit will not
cool adequately.

Cooler Installation

• High and low cool settings. The “High Cool” and “Low Cool” set-

tings operate both the pump and the blower. T urn 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 effi ciency.

• 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.

Remote Control Units

These units may be controlled using the 3 buttons on the front panel
of the cooler or with the remote control.

• PUMP button. Pressing this button toggles the pump on and off.

When the LED is lit, the pump is running. For best results turn
on the pump for a few minutes to wet the pads before operating
the fan. The pump must be on while operating the fan for cooling.
You may also want the pump turned off at times when just a fan is
desired.

• FAN button. Pressing this button will cycle the fan through High

Speed / Low Speed / Off. The LED’s on the front of the control
indicate wether the fan is on high speed, low speed or off (no LED’s
lit). Note: There will be a 2 second delay between a button press

and the operation of the fan.

• ON/OFF button. Pressing this button while the pump or fan is on

will turn everything off. Pressing it again while in the off state will
return the fan and pump to their previous operating settings. When
fi rst plugging in the cooler or after power has been interrupted,
pressing the On/Off button will start the cooler in the default state
which is with the pump on and the fan on high.

Installing Casters

Note: The installation kit

includes (2) swivel cast­ers with brake, (2) swivel
casters without brake, (16)
tinnerman nuts and (16)
1/4-20 x 1/2 screws.

• Place the unit on its side.
Place the tinnerman nuts on
the caster bracket on the bot­tom pan as shown in fi gure

1.

• Attach the casters to the
brackets with the screws provided.

Connecting Water

• Install drain assembly. Place the
nipple through the hole in the pan,
with the rubber washer between the
pan and the head of the drain nipple
(Fig. 2). Thread nut onto nipple and
draw up tight against bottom of pan.
Thread the drain cap to the nipple and
tighten water tight.

• Install fl oat valve. Refer to fi gure 3. Install the valve in the pro-
vided hole in the corner post ((R)M301A, (R)M401A) or louvered
side (M201A) using the provided washer and nut. Install the
included garden hose adapter to the fl oat as shown if attaching a
garden hose to the unit. A 1/4 inch water line may also be used to
supply a continuous amount of water to the unit.

• Remote Control. To operate the cooler with the remote you must

be within 20 feet and in sight of the cooler. Aim the remote at the
front panel. The buttons on the remote control have the same func­tions as the buttons on the front panel of the cooler. The remote
uses two AAA alkaline batteries which are included. A holder for
mounting on a wall is also included with the unit.

Note: Do Not Overfi ll. Fill water to a maximum height of 2 1/2

inches (approximately 1 inch from the top of the bottom pan). If
using a garden hose, the fl oat will need to be adjusted to maintain
this water level. This can be accomplished by bending the fl oat
rod.

is necessary once a year at start-up.
For your safety, turn unit off and unplug unit and pump. Remove
the pump from the mount slot. Remove the base of the pump (Fig.

Annual Maintenance

• Oil bearings. The blower bearings (M401A & RM401A only)

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 does
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.

CAUTION: Do not over oil. Over oiling can cause motor burn

out, due to excessive oil getting into motor winding.

• Change Pads. 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 effi cient and will
deliver substantially more cool air.

• Check belt and belt tension. This applies only to models

(R)M401A which are belt driven. Models M201A and (R)M301A
have direct drive motors. Check the belt for any cracks or wear and

Routine Maintenance

• Drain water. It is recommended to drain the water from the

cooler at least once a week. Keeping fresh water in the pan will
help prevent scale and mineral deposits accumulation on the pads.
Always drain all of the water out of the cooler when not in use for
prolonged periods, and particularly at the end of the season.

• Unplug unit from power supply during extended periods of
non-use.

• Cover unit or store inside when not in use.

By following the operating, installation, and maintenance suggestions
as outlined, you can get many years of effi cient and satisfactory
service from your cooler. In the event additional information is
desired, your dealer will be more than glad to assist you in every
possible way.
