WASHINGTON, DC -- Dial Manufacturing, Inc. of Phoenix, AZ, in cooperation with the U.S.
Consumer Product Safety Commission (CPSC), has voluntarily initiated a replacement program
for 150,000 Model D5500 evaporative water cooler pumps sold in 1990 and 1991. Some of the
pumps may have misaligned motor bearings that could cause the pumps to fail and, under
certain conditions, catch fire.
A total of 119 pump fires have been reported to Dial since 1990. Ninety-eight of the fires
reported occurred in the El Paso, Texas area. Most of the fires resulted in property
damage to the cooler cabinets and/or home roofs. No injuries were reported.
Evaporative coolers, commonly known as swamp coolers, are designed to blow moist cool air
through ducts into a residence. They are generally found in the drier climates of the
western and southwestern United States. The box shaped evaporative cooler cabinets are
constructed of plastic or metal and are often installed on top of house roofs.
A water cooler pump such as the Dial D5500 model is located inside the cooler cabinet. The
pump functions to draw supplied water from the reservoir at the bottom of the cabinet to
the distribution system at the top. Water then saturates the cooling pads located
vertically inside the vented cabinet. Outside air is cooled and humidified as it is pulled
through the pads by the cabinet blower. The blower then forces the moist cool air into the
Because of the corrosive nature of the cooler environment, economy pumps such as the D5500
reportedly last only one season. However, some of these pumps are still in service.
The 1990 Dial D5500 cooler pump has a blue plastic housing and has "1990 Taiwan"
inscribed on the base plate. Consumers who identify this blue cooler pump should stop
using their evaporative coolers until the pump is replaced.
Dial will replace any 1990 blue D5500 cooler pump free of charge with a new 1991 red and
white D5500 pump or a 1992 red and white D5000 pump. Consumers should call Dial toll free
at 1-800-350-3425 and ask for the returned goods department or write to Dial at 2252 Grand
Avenue, Phoenix, Arizona 85009.
