move to non GFCI outlet.

5. Water leakage
5.1 Check the cap of the drain assembly, make sure it 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 of the 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.

6.1 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.oem-tools.com
