1. Fan Does Not Operate
A.)
Check voltage requirements on unit and electrical supply. Check for live receptacle, plug,
and power line.
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 #52) and make necessary
adjustments. Retighten bolts.
3. Unusual Noise
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.)
Check to see if flow control valve is open. The valve is open when the handle is down
and closed when up. If the valve is open and there is still no fog, the pump may need
to be primed. In rare cases the pump may retain an air bubble. To prime the pump,
remove the inline strainer cap (Part #71) and turn the system ON for a few seconds.
Replace cap and try operating unit again.
B.)
If pump is receiving electricity but there is no fog, check for sediment in the pump's
intake screen. Spray around the pump with a garden hose or remove the pump
and thoroughly clean the intake screen. Clean and flush out the tank area by removing
the drainage plug located on the bottom rear of RSM.
C.)
If no liquid enters the tank when using the automatic fill, check float valve assembly for
debris. When the float arm is up, water should shut off; when it is down, water should
freely enter RSM tank.
5. Liquid Spilling From Overflow Port
A.)
Check the float valve assembly. If the float (Part #99) is filling with water, it should be
replaced. Also check to see if debris is not allowing the valve (Part #97) to seal properly.
Clean as needed.
B.)
Reduce the in-line water pressure.
6. Liquid Spilling From Fan Housing
If liquid builds up inside the housing, the drain tube is probably clogged. Clean debris
from the drain strainer and drain tube.
