Page 3: Introduction
INTRODUCTION WHY USE EVAPORATIVE COOLERS IN YOUR WORKPLACE? ® • The WayCool evaporative cooler requires little space, has a low initial cost, is inexpensive and simple to operate and requires minimal scheduled maintenance. • Due to the design and construction of the cooling pads, cooling efficiency is normally maintained near optimum throughout the life of the pads, which can easily last for about two seasons with proper care. -
Page 4: How Evaporative Cooling Works
INTRODUCTION HOW EVAPORATIVE COOLING WORKS Figure WC-1HP-DHL.02 - Evaporative Cooling Principle Evaporative cooling is the same process your body uses to cool itself. When you perspire, and air moves across your skin, a portion of the perspiration (water) evaporates. Evaporation requires heat to change liquid water-to-water vapor and this heat is taken from your skin, producing the cooling effect. -

Page 11: Water Supply System
The bottom can be supplied continuously with an ordinary garden hose by attaching the supplied hose adapter (see Figure WC-1HP-DHL.08) to the fill connection, or it can be filled manually. With a continuous water supply connected, the float valve in the bottom (like the one in your toilet tank) rises and falls with the water level. - Page 12 The pump can be easily removed and replaced with the services of a qualified electrician. Plastic Screen Pump Impeller Figure WC-1HP-DHL.06 – Pump A small plastic screen covers the pump inlet to prevent foreign matter from entering and damaging the pump impeller. The screen snaps in place and can be easily removed for inspection or cleaning.
- Page 13 WATER SUPPLY SYSTEM A clear vinyl hose connects the pump to the filter. From the filter, a "T" connector supplies two lines that run along the bottom and up opposite frame corners to supply the PVC pipe with water. Each vinyl hose connects to two PVC pipes, which run horizontally along the top of the frame above the cooling pads.

Page 14: Cooling Pad Assembly
COOLING PAD ASSEMBLY The cooling pads are critical for proper, efficient cooler operation. They are made of laminated cellulose (paper) fibers and arranged to give a large surface area for evaporation and to provide a rigid structure. The shape of the cells allows high velocity airflow through the pad at a minimum pressure drop. At the same time, the air passages between the cells force the incoming air to impinge on the wet cell surfaces and maximize evaporation. -

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. -
