WHAT ASSEMBLY IS REQUIRED?

None. Evaporative air coolers are ready to use right out of the box.

Evaporative air cooler replacement parts may be purchased from any DBA product distributor or directly from DBA Parts/Technical Support department. You may also visit www.DBA.hk to order online.

Misting units spray a shower of water into the air that will collect on people, objects, equipment, floors, etc.  Evaporative air coolers use the process of evaporation to produce cooler air, but do not discharge a mist.

For optimum performance, the temperature should be 33 degree or higher and the relative humidity should be below 75%. However, Evaporative air coolers will reduce the temperature in almost any environment, making it more pleasant.

An increase in humidity of approximately two to five percent is produced, depending on the temperature and humidity of the environment. This increase is not noticeable in a ventilated area where the air produced by the evaporative coolers is exhausted.

Drain the evaporative coolers, dry out the pads and place the evaporative coolers, preferably covered, in a dry place for the winter season. For more details, please call our Tech Support Hotline at 2541-1611.

Some of the vapor from the ice water may be picked up and distributed by the evaporative cooler, but this does not increase evaporation and therefore will not produce significant cooling.

First, make sure the water source and electricity source are connected and working. Second, check the back of your evaporative cooler to see if the pads are damp. Adjust the water flow. For the evaporation process to occur, the pads must be damp before you turn on the fan. Third, make sure there is water in the tank. It should be allowed to fill before you turn the pump on. Fourth, if none of these options fix the problem, call our Tech Support Hotline at 2541-1611 for additional assistance.
