About Cool-Space 400

How does the cooler work?

As air passes through the wet cooling media (pads), it absorbs the moisture. This moisture absorbs the heat in the air, reducing the air temperature the same way rain does on a hot summer day.

Does the cooler add humidity?

Yes, but only a slight amount. The area needs a constant flow of fresh air to prevent the air from being re-humidified.

How much of a decrease in temperature does the cooler provide?

Typically the cooler provides an 8- to 33-degree drop depending on the existing dry bulb temperature and relative humidity.

How much water does the cooler use?

On average, the cooler uses 2 to 10 gallons of water per hour depending on the dry bulb temperature and relative humidity.

Does the cooler spray or mist water?

No, moisture is added to the air in a vapor state. As a result, the cooler will not create puddles or wet spots.

How long does the cooling media (pads) last?

The cooling media will last 1 year and 6 months if it is in a dirty environment. If you have hard water, using the water treatment tabs available by calling Big Ass Fans will help prolong the life of the media.

 
How effective is the cooler in humid climates?

The air temperature and relative humidity will determine the effective temperature drop. Even in humid climates, you can expect around an 8 degree temperature drop. This drop in temperature combined with the cooler’s high velocity fan can create a chill factor of 15–20 degrees.

Trouble with Something Else

Pump motor will not run when switch is turned on.

Turn fan on to check for power.

  • If fan does not start, check breaker and make sure cord is plugged in.
  • If fan starts, check for power to and through pump switch (when turned on).

How do I replace my cooler’s pump?

WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death.

  1. Unscrew fitting from pump.
  2. Unplug cord from top of pump by removing the two (2) screws.
  3. Remove pump from water sump and install new pump.
  4. Perform the steps above in reverse to reconnect the wiring, lift the pump bracket, and reconnect the hose.
  5. Secure wires to fan frame with wire ties so that wires are clear of fan blades. Ensure plug is positioned correctly.
  6. Reinstall cooling pads and guards.
  7. Reconnect power and test pump.
How do I replace my cooler’s fan motor?
