Thermometer Replacement
If the thermometer does not read correctly and cannot be adjusted with the control on front of the console, the
entire assembly is removable and can be replaced by the operator. Call Retrotec.
Fan Makes Scraping Noise When Turning
Check to see if the blade hits the screen or the edge of the white plastic tube. Adjust the position of the
0
motor by loosening two (2) bolts (180
opposed) and adding or removing washers. Keep the total number of
washers used the same. Check to see if a screen bracket is loose. Re-attach.
Possible Electrical Problems
Motor Does Not Turn
Check outlet. Ensure red rocker switch is on. Did motor overheat and trip its overload? If so, wait 20 minutes,
but turn speed control down or off. Is blade free to turn? Check it with a pencil - if it does not glide, it may
be rubbing or the blade may have moved forward on the shaft. If all is in order, the speed control may be
defective. Plug the blower into a wall outlet with a standard extension cord. If it goes full speed, the
controller is at fault.
Blower Speed Wanders
Small changes in voltage cause the blower speed to fluctuate up and down. Nothing is abnormal if this happens
but watch HOUSE PRESSURE and FLOW PRESSURE gauge as they move together and obtain a set of readings
simultaneously.
