Champion WCM28 - User Manual

A user manual for window-mounted evaporative coolers like the Champion-Essick models WCM28 and N28W covers essential topics such as installation safety, airflow optimization for cooling efficiency, and proper maintenance routines. The guide emphasizes balancing ventilation through windows while warning against unsafe modifications like solid-state fan controls. It also includes detailed setup instructions–including mounting, water supply connections, and seasonal shutdown procedures–and troubleshooting common operational issues like starting failures or inadequate cooling. Maintenance sections highlight cleaning the pump, lubricating the motor, and winterizing the unit to prevent damage. The manual further provides a replacement parts list with specifications for cabinet dimensions, electrical requirements (voltage/amperage), and warranty details.

only.

4. Motor and pump are grounded and have an automatic thermal

overload switch which will shut motor off when it overheats. The
motor will restart automatically when it cools down.

Evaporative Cooling

With this unit being a fresh air system, you are not trapped with
recirculating air that can become stale, laden with smoke and odors,
as happens with refrigerated air conditioning systems. Instead,
you are completely replacing the air every 2 to 4 minutes by either
opening doors or windows or a combination of both to exhaust the
air continually.

How much should you open your windows? To obtain the maximum
cooling capacity of your cooler, you should open your windows until
the air inside the house is nearly balanced with the air outside. As
you open your windows you decrease the pressure buildup inside the
home, and the cooler is able to output increasingly more air until the
capacity of the cooler is reached.

One method to determine when the air is reasonably balanced is to
place a piece of tissue paper up against the screen of the window
furthest from the cooler and adjust the opening of the windows in the
house until the tissue paper stays lightly on the screen. If the tissue
plasters itself to the screen, open the windows more. If it falls, close
the windows more.

Operation

To eliminate delivery of hot air when starting cooler, turn on pump
only for the fi rst few minutes, then turn on the blower motor.

These coolers may be used without water for ventilation purposes.
When outside air is cool (for example, at night) or when humidity is
high the water pump can be turned off.
