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.
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.
ABOUT THIS MANUAL The intent of this manual is to help you in two ways: to provide you with step-by-step instructions for quick and easy assembly of your product and to serve as a reference for simple maintenance and questions regarding your product. Important! Read ALL instructions carefully before starting your WayCool®. Important! Pay particular attention to all SAFETY information.
SAFETY INFORMATION Warning and Danger Decals have been placed on the equipment to warn of potentially dangerous situations. Care should be taken to keep this information intact and easy to read at all times. Replace missing or damaged safety decals immediately. Using the equipment for purposes other than specified in this manual may cause personal injury and/or damage to the equipment. Safety-Alert Symbol This is a safety-alert symbol.
SAFETY INFORMATION Follow Safety Instructions Carefully read all safety messages in this manual and on your equipment safety decals. Follow recommended precautions and safe operating practices. Keep safety decals in good condition. Replace missing or damaged safety decals. Decal Descriptions This diagram shows the proper location of the safety decals as shipped from the factory. Replace damaged or missing decals. Make sure the decals are easy to see at all times.

WC-1HP-DHL UNIT DESCRIPTION The WayCool® evaporative cooler is a completely self-contained, portable unit capable of delivering 40 MPH velocity of air with a temperature drop of up to 20°. The unit is composed of: • Level-controlled water supply system • Cooling pad assembly • Motor-driven blower and ductwork • Controls • Frame and housing The bottom is made of high impact ABS plastic and holds approximately 24 gallons at normal operating level (about 5" deep).
WATER SUPPLY SYSTEM Actual WC-1HPDHL WayCool® Varies slightly from unit shown here. Figure WC-1HP-DHL.05 – 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.
WATER SUPPLY SYSTEM A drain in the bottom allows you to drain the unit for cleaning and maintenance. A drain cap on the underside of the aluminum tray covers the drain during operation. Make sure the cap is in place before you fill the bottom. The drain cap should be finger-tightened only. The pump is attached to a bracket which in turn is fixed to the blower housing.
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. Water Supply System The PVC pipes have a series of holes that run the full length of the pipe.
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.
BLOWER AND DUCTWORK Actual WC-1HP-DHL WayCool® varies slightly from unit shown here. 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.
CONTROLS Manual Motor starter switch ON/OFF – single speed Pump Selector Switch Figure WC-1HP-DHL.08 - WayCool Control Switch Both the manual Motor starter switch and the Pump switch function as ON/OFF only. The unit can run with pump only ON, fan (motor) only ON or both ON.
OPERATION & MAINTENANCE UNIT PLACEMENT AND OTHER CONSIDERATIONS Figure WC-1HP-DHL.09 Typical WayCool® Unit Arrangement The WayCool® unit(s) 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® unit 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® unit.
OPERATION & MAINTENANCE Operation and Maintenance UNPACKING AND INITIAL SETUP The WayCool® WC-1HP-DHL Evaporative Cooler is shipped upright in a corrugated container. The WayCool® WC-1HP-DHL is fully assembled and ready for service except for thoroughly cleaning manufacturing dust from the cooling pads before running it for the first time. CAUTION: Be careful when you move the unit while it is in the shipping container and when moving it around with the container removed.
OPERATION & MAINTENANCE 9. Ensure the frame legs are straight and in alignment, and that the blower is sitting level and in proper position. Maintenance Note: If you notice any damage to your unit, immediately contact the dealer where you purchased it. 10. Clean thoroughly all eight cooling pad sections using a garden hose. Note: Do not use cleaning fluids or other chemicals to clean the pads or it can cause foaming during operation. Use only clean water. 11.
OPERATION & MAINTENANCE NORMAL STARTUP 1. Place the unit in the position where it will be run. Do not attempt to lift or move the unit once it is filled. Damage to the unit or a large spill may occur. Note: When you decide where to place the unit, make sure there are no obstructions in the way that will disrupt or block the airflow. Make sure the unit is level at all times. Keep the unit at least three feet away from walls or other obstructions that will interfere with airflow into the unit. 2.
TROUBLESHOOTING COOLING PADS NOT WETTING 1. 2. 3. 4. Ensure that the bottom has water. Ensure that the motor switch is in the start position and the pump switch is in the on position. Ensure that the pump is running. Pump is running but no water: a. Ensure hose is connected. b. Inspect and clean the pump discharge filter. c. Inspect and clean the pump intake filter. d. Ensure the impeller on the inside of the pump turns freely – see figure WC-1HP-DHL.05 – Pump. e. Filter may have an air lock.
TROUBLESHOOTING SPLATTERING Out Front See “ Line Clogs or Obstructions”. LEAKING Out Bottom Check for cracks on the bottom. If a crack is found, a new bottom will have to be ordered. See “Ordering Replacement Parts – page 24.
