Portable Evaporative Cooler WayCool® 1HP MFA Series USER'S MANUAL WC-1HPMFAOSC WC-1HPMFA WC-1HPMFA360 WCG-1HPMFA
Using this equipment for any other purpose than it was intended or in a way not within the operating recommendations specified in this manual will void the warranty and may cause personal injury. This manual is designed to provide comprehensive planning, installation, safety, operation, maintenance, troubleshooting and parts information. If a problem should arise, or if replacement parts are needed, your Schaefer dealer can supply the necessary information to help you.
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 (approximately two seasons).
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 you may have regarding your product. Read ALL instructions carefully before starting your WayCool®. Pay particular attention to all SAFETY information. Optional equipment contains necessary instructions for assembly and/or operation.
Safety Recommendations READ AND SAVE THESE INSTRUCTIONS! This is an electric device with moving components. There is the possibility of fire, electric shock or injury to persons. Ensure all the safety recommendations are adhered to in order to minimize this risk. • Disconnect all power and unplug the unit before you inspect, clean or perform maintenance on the components of the 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 degrees F. The unit is composed of: • • • • • Level-controlled water supply system Cooling pad assembly Motor-driven blower and ductwork Controls Frame and housing The reservoir is made of high impact ABS plastic and holds approximately 24 gallons at normal operating level (about 5" deep).
Water Supply System Actual WayCool® may vary slightly from unit shown here. Water Supply System The reservoir can be supplied continuously with an ordinary garden hose by attaching the supplied hose adapter to the fill connection, or it can be filled manually. With a continuous water supply connected, the float valve in the reservoir (like the one in your toilet tank) rises and falls with the water level. A linkage attaches the float to the shutoff valve in the fill connection.
Water Supply System cont'd A drain in the reservoir 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 reservoir. 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 WayCool® may vary slightly from unit shown here. Fan Blower 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.
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.
Operation and Maintenance cont'd UNPACKING AND INITIAL SETUP The WayCool® is shipped upright in a corrugated container. The unit 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. Avoid jarring or dropping the unit. 1.
Operation and Maintenance cont'd REGULAR CLEANING The frequency with which the WayCool® should be 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. Ensure there is water in the reservoir. 2. Ensure the motor switch is in the START position and the pump switch is in the ON position. 3. Ensure 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. 5. Pump is not running: a.
Options and Accessories Your WayCool® can be purchased with certain options and/or accessories, and some of these can be retrofitted after the initial purchase. Instructions are included with all equipment purchased separately.
Options and Accessories cont'd OSCILLATING SPOUT Oscillator Switch The oscillating spout is operated by a four RPM gear motor that delivers 50 in/lbs. of torque. As the gear motor rotates, the spout oscillates in a 110-degree arc, which cools an area of about 9500 square feet. On/Off Switch Oscillator Assembly The design of the oscillator requires the spout to sit loosely on top of the unit.
