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.
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®. • Optional equipment contains necessary instructions for assembly or operation. Important! Pay particular attention to all SAFETY information.
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-1/3HP Unit Description The WayCool® evaporative cooler is a completely self-contained, portable unit capable of delivering 25.5 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 14 gallons at normal operating level (about 4" deep).
Water Supply System Actual WC-1HP ® Actual WC-1/3HP-DHL WayCool® variesWayCool slightly varies slightly from unit shown here. from unit shown here. Figure WC-1/3HP.05 - Water Supply System The bottom can be supplied continuously with an ordinary garden hose by attaching the supplied hose adapter (see Figure WC-1/3HP.07) to the fill connection, or it can be filled manually.
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.
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-1/3HP uses a direct drive, 1/3 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 Figure WC-1/3HP.08 - WayCool® Control Switch The WayCool® WC-1/3HP control switch is mounted on the outside of one frame leg (see cover fig). 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.
Operation & Maintenance Unit placement and other considerations Figure WC-1/3HP.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. It will counter the WayCool®'s airflow and stop the cooling effect.
Operation & Maintenance UNPACKING AND INITIAL SETUP The WayCool® WC-1/3HP Evaporative Cooler is shipped upright in a corrugated container. The WayCool® WC-1/3HP 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 REGULAR CLEANING The frequency with which the WayCool® is cleaned will depend on the environment in which it is used. The more dirty the environment the more often it will need cleaning. In most cases the WayCool® will need to be cleaned weekly. Caution: The pads should be dry before you handle them, as they are stronger when dry than when they are wet and less susceptible to damage. If they are wet, run the unit in the HIGH VENT position until they are dry.
Troubleshooting COOLING PADS NOT WETTING 1. 2. 3. 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. 4. 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.05 - Pump. 5. Pump is not running: a.
Optional Accessories Your WayCool® Evaporative cooler can be purchased with accessories/options or some of these options can be retrofitted to your WayCool® after the initial purchase. Necessary instructions are included with all equipment purchased separate from your WayCool®.
Optional Accessories Oscillator WayCool® Oscillating Switch On/Off Switch Oscillating Assembly The oscillator, in this WayCool® unit, is operated by a 4 RPM gear motor (WC-OSCGEARMTR) that delivers 50 in/lbs. in torque. As the gear motor rotates, the blower duct (WC-SMBLOWERDUCT) oscillates in a 110-degree arc, which cools an area of approximately 9500 square feet. * The design of the oscillator requires the blower duct to sit loosely on top of the unit, do not tighten it down.
Optional Accessories Automatic Shutoff Option The Automatic Shutoff Option (WC-ASOKIT) is available at the time of your WayCool® purchase or as a retrofit kit on a previously purchased WayCool®. The WC-ASOKIT shuts off the pump when the water level gets low and prevents the pump from damage. The warranty on the pump is void if it is run dry.
