WARNING
4. No Fog
A.)
The self-priming system will usually take about 10 seconds before you see fog output.
Check to see if the flow control valve is open. The valve is open when the handle is down.
B.)
Check the pre-set flow rate valve located inside the tank (refer to page 6 Factory Pre-set
Flow Valve). Having the pre-set flow rate valve in either a fully closed or fully open position
will result in no fog output. If the positioning is incorrect, refer to
page 6
for instructions
on calibrating the pre-set flow rate valve.
C.)
Check for sediment clogs. Flush the inline strainer and check for sediment build-up
around the base of the pump. Spray around the pump with a hose and drain the tank.
D.)
The pump may not be operating. Check by removing the Inline strainer cap and turning
system On. If no fluid flows from the strainer, the pump may need to be replaced.
5. Unusual Noise
It is normal to hear a slight rattling noise at start-up and shut-down. This is caused by the tip
of the liquid feed tube entering the center of the fan blade assembly reservoir.
6. Fan Motor Becomes Excessively Hot
The main fan motor normally becomes very hot to the touch. However, it should not get
so hot that it begins to smell or smoke, nor should the power cord become hot. Discontinue
operation and consult an electrician to properly evaluate the problem.
7. Electrical Breaker Tripping
If the electrical breaker trips off, there is an overload in the system and there may be a
serious motor problem. Turn off all other devices connected to the same circuit. If the breaker
continues to trip, the motor is probably in need of repair. Consult an electrician for evaluation.
8. Fan and/or Motor Vibration
If the fan unit begins vibrating severely, first be sure the blade assembly is fully engaged
and securely tightened on the motor shaft. Next, inspect the blade assembly, particularly the
ends of the blades. Look for wear or cracks - replace as necessary. Look for deposits of
calcium or minerals - clean and remove mineral deposits and/or calcium. Also check that the
motor mounting hardware is securely tightened.
