BLOWER AND DUCTWORK

The WayCool evaporative cooler uses a belt-driven, 1 Hp electric motor to drive a centrifugal blower. The blower draws room air through the cooling

pads and discharges the cooler air through the spout, displacing the warmer air with cooler air and decreasing the temperature.

The blower is secured to the top of the frame and hangs upside down to direct the air out the top of the unit. Brackets on each side of the blower cas-

ing secure the blower to the frame and hold it in position.

The electric motor is bolted to a metal bracket on the blower casing. A V-belt connects the pulley

on the motor shaft to the larger pulley on the blower shaft. Both shafts have sealed roller bearings,

which do not require lubrication.

A belt tensioner is connected to a bracket on the motor. A rubber foot at one end rests against the

blower bracket that is attached to the blower casing. When the locking nut is backed off, the bolt

can be turned in to tighten the V-belt or backed out to loosen or remove the V-belt.

Do not over tighten the V-belt as you can prematurely wear out the bearings.

The power cord runs down the frame leg that has the control switch on the outside. It exits the

frame leg at the bottom and has a male plug that must be plugged into a suitable GFCI-protected

receptacle. The cord is approximately nine feet long.

The standard unit requires 120 volts and 15 amps of power. This is normally available on most

circuits. However, if you are running a number of other items on the same circuit, you may trip the breaker.

CONTROL

The WayCool control switch is mounted on the outside of one frame leg.

It has the following positions:

OFF power is off to the blower motor and the pump motor.

LOW VENT the blower runs at low speed and the pump is OFF.

HIGH VENT the blower runs at high speed and the pump is OFF. Use this setting to quickly dry the cooling pads

for removal and cleaning.

LOW COOL the blower runs at low speed and the pump is on. Use this setting for low cooling loads.

HIGH COOL the blower runs at high speed and the pump is on. Use this setting for maximum cooling.

PUMP ONLY pump is on and the blower is off. Use this setting during startup to ﬁrst saturate the cooling pads, then switch to LOW COOL or HIGH

COOL to begin cooling.

OPERATION AND MAINTENANCE

The WayCool should be placed at one end of the building and an appropriate exhaust fan should be at

the opposite end to pull the cool air from the WayCool and discharge the warm air out of the building.

Try to get all the air ﬂowing in the same direction. Do not direct other fans against the WayCool as they

will counter the airﬂow and hinder the cooling effect.

Obstructing the airﬂow from the WayCool severely reduces the cooling effect.

Avoid using ceiling fans as they disrupt the airﬂow from the WayCool.

Use as many exhaust fans as possible to create a natural draft through the building. This will enhance the

performance of the WayCool.
