Troubleshooting

COOLING PADS NOT WETTING

1. Make sure the unit has water.
2. Check to insure the control switch is in the proper position.
3. Make sure the pump is running.
4. Pump is running but no water:
a. Ensure hose is connected.
b. Ensure the impeller on the inside of the pump turns freely.
5. Pump is not running:
a. A certified electrician must check wiring from pump to pump selector switch.
b. If the wiring is correct, replace the pump.

FOAMING

Foaming is generally caused by a dirty water supply or contaminated water in the bottom.
1. If foaming occurs, stop the unit, drain it and flush the bottom and insides thoroughly with clean water.
2. Clean the pads and do not use any kind of chemical cleaners. Refer to the REGULAR CLEANING section
for proper procedure for cleaning the pads.
3. Reassemble, refill and restart.
LINE CLOGS OR OBSTRUCTIONS (little or no water flow)
Depending on the cleanliness of the water and the amount of dirt, dust, etc. in the supply air, you may have to
clean the PVC pipes from time to time. Your own experience will dictate the frequency.
1. Turn off the unit and unplug it.
2. Remove the pads.
3. Locate the two PVC pipes in the top housing. Each PVC pipe is secured to an elbow connector by a hose.
Remove this clamp from both PVC pipes.
4. Grip the opposite end of each PVC pipe with pliers and gently twist it out of its Y connector.
5. Direct a jet of water at the series of outlet holes in the PVC pipes to blow them clear.
6. Direct the water nozzle into the end of each pipe and blow them clear. Inspect them for cleanliness and
repeat if necessary.
7. Replace the PVC pipes taking care to ensure the water outlet holes are facing inwards at 90° towards
deflector plate.
Be sure you push the PVC pipes fully onto the elbow, and attach hose clamps.

LEAKING FROM THE BOTTOM

Check for cracks in the reservoir. If a crack is found, repair it by using a Pro-Kool
