7. Poor Quality Fog
A.)
The liquid feed tube (Part #575) may not be properly positioned. The feed tube is located
behind the blade assembly and should be inserted approximately 1/4" into the slot
between the motor shaft and the stainless steel face plate. Centered in the slot area and
aimed slightly downward, free from any rotational contact.
B.)
Liquid not traveling through the fan blades. This can be diagnosed by viewing the back
of a blade assembly during operation (using a bright flashlight). If system is clogged,
liquid can be seen spinning out of the slot area between the motor shaft and stainless
steel face plate (Part #573). If confirmed, replace fan blade assembly (Part #571-assy).
Cleaning the internal passageways of a blade assembly is feasible with the aid of some
speciality tools.
8. Fan Motor Becomes Excessively Hot
The main fan motor normally becomes very hot to the touch. However, if it gets so hot that it
begins to smell or smoke or the power cord becomes hot, discontinue operation and consult
an electrician to properly evaluate the problem.
9. 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.
10. Fan and/or Motor Vibration
A.)
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.
B.)
If the vibration seems to be coming from the motor, first check that the motor mounting
hardware is securely tightened. If hardware is secure, remove the blade assembly and
operate the motor without the blade. If vibration continues, the motor has a serious
mechanical problem and probably needs to be replaced.
11. Plumbing Leaks
Un-thread fittings and clean both the male and female threads. Apply new thread tape
(approximately 2-3 wraps) and reconnect. If a tube fitting is leaking, tighten the cap - no
more than 1 turn past finger tightened. If the leak persists, replace the tube fitting insert.
