Troubleshooting

1. Water is not flowing

a. Check to be sure there is water in the tank and it is covering the pump

b.Check water hose to be sure there are no kinks. Water hose should be pushed fully onto both the water outlet and pump

c.Make sure pump is fully seated in slot at bottom of main housing

d.Turn unit off, then back on to help clear any air in the system

e.If water still is not flowing, remove pump, disassemble and make sure pump impeller can spin freely and there is nothing blocking pump inlet or other water passages

f.Make sure the grille is fully seated and can accept water from the supply funnel

2.Unit flows water but does not produce mist

a.This unit does not produce visible mist

3.Unit flows water but filter is not moist

a.Check to be sure the holes in the water feature are not blocked and can drip water onto the filters

4.Pump makes a swishing sound

a.The pump may have sucked in air. Be sure there is enough water in the tank to cover the pump.

b.After filling, turn the unit off for a few seconds, then turn it back on to clear the system of air.

5.Pump makes a whirring sound

a.The pump may not be properly seated. Be sure to push pump fully into slot in main housing. After seating the pump properly, turn the unit off for a few seconds, then turn it back on. This will allow the pump to synchronize with the drive magnet.

6.Unit has poor output

a.Make sure the filters are moist and you can feel airflow coming through the filters.

b.Make sure the water fill baffle and grille are properly seated.

c.If both a and b are OK, the relative humidity in your home could be high. The unit will automatically regulate the output based on the amount of humidity already in the air.

7.Unit makes dripping or trickling sound

a.Make sure the fill funnel is properly assembled and mounted in the tank behind the water window.

b.Make sure the grille is properly seated and the fill funnel can accept water.

c.Make sure the mesh supporting the filter is not damaged.
