- Prior to putting your cooler away for winter, always:
- a. Drain the tank and wipe clean.
- b. Clean the rigid media.

Troubleshooting
| Problem | Cause/Remedy |
|---|---|
| 1. Cooler fails to work at all | 1.1 Check that the unit is plugged properly. 1.2 Check the POWER switch, push it to "ON". 1.3 The TIMER switch is "OFF", turn it to "ON". 1.4 Make sure cooler is not plugged into a tripped GFCI outlet. If so, reset GFCI or move to non-GFCI outlet. |
| 2. Cooler does not pump | 2.1 Pump is not activated. Push the PUMP switch to "ON". 2.2 Water level is low. Fill with water and make sure pump is activated. 2.3 Be sure the pump and pump hose are clear of debris. 2.4 Pump may be defective. Replace pump. *** |
| 3a. Fan does not operate | 3.1 Check that unit is plugged properly. 3.2 Check the POWER switch, push it to "ON". 3.3 If connected to a GFCI outlet, check if it is tripped. 3.4 Troubleshoot rotary switch. *** |
| 3b. Fan runs slow at start up | 3b.1 Replace motor capacitor. *** |
| 4. Louver does not operate | 4.1 Louver does not move. Put swing switch position to "ON". 4.2 Check Oscillator motor for proper placement and operation. |
| 5. Water leakage | 5.1 Check the cap of the drain assembly, make sure it is tightened. 5.2 Inspect tank for cracks or breakage. 5.3 Make sure cooler is level. 5.4 Check media pads for buildup allowing water out on outside of pad frame -- change media if needed. 5.5 If water is coming out fan, check for leaks in water distribution hoses and/or leaks at hose connections to spreaders. 5.6 Be sure there is at least 4 inches of space for rear panel free from wall or other obstruction. This could make the side panels release water to airstream due to increased air velocity through the sides. 5.7 Spreaders may have scale buildup allowing water to pool and spill over into airstream—Clean spreaders. |
| 6. Float Valve | 6.1 If water levels are too high/low, adjust the wing nut on the valve. 6.2 If there is a leak, check for cracks. Purchase new valve at www.hessaireparts.com |
