Figure WC-1HP-DHL.07 - Fan Blower
The WayCool
®
WC-1HP-DHL 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 blower duct, 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 casing 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.
Blower and Ductwork
A belt tensioner is connected to a bracket on the motor. A rubber foot at one end rests against 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.
Note: 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 hazardous location receptacle. The cord is
approximately fifteen feet long.
Note: The WC-1HP-DHL unit requires 120 volts and 20 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.
