1. Fan Does Not Operate
A.)
Check voltage requirements on unit and electrical supply. Check for live receptacle, plug,
power line and toggle switch.
B.)
Look for any loose connections inside the main motor's junction box.
2. Blades Rub Against Venturi
A.)
To make a horizontal adjustment, loosen the 4 bolts (Part #56) at the base of the main
fan motor and shift motor side to side until centered. Retighten bolts.
B.)
To make a vertical adjustment, slightly loosen 4 bolts (Part #117) and make necessary
adjustments. Retighten bolts.
3. Unusual Noise
A.)
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.
B.)
Squealing at start-up or during operation may be caused by the motor shaft's bearing
seal. Spray with lubricant at the front of the motor where the shaft exits the motor's
frame.
4. No Fog
A.)
If the flowmeter is closed, turn the flow control knob counter-clockwise to increase fogging
output. Visually check for sediment clogs within the flowmeter's body and remove inline
strainer's cap to flush any debris from screen. Refer to the maintenance section for
flowmeter cleaning instructions.
B.)
If the fan is automated and the water is supplied through a water solenoid, check to see if
the solenoid is electrically activated by the control and check the solenoid for clogs.
C.)
If after checking both the flowmeter and solenoid, you still do not have any fog, begin a
process of elimination starting with the water source. Disconnect and reconnect your
plumbing before and after each device to check for any obstructions.
5. Poor Quality Fog
A.)
The liquid feed tube (Part #6) may not be inserted properly into the reservoir. The feed
tube must be inserted approximately 1/4" into the center bearing, but it should not touch
the back of the reservoir.
B.)
Reservoir may be clogged. Fluid entering a clogged reservoir will spill out of the center
bearing instead of entering the passageways of the fan blades. To clean, remove the
blade assembly from the motor shaft and totally disassemble. Next, flush the reservoir
under a sink, making sure the passageways are cleared. Check and clear the pas
sageways of each individual blade as well. Reassemble and reattach.
