compressor hums
by: Bob

thank you for your help. I have this unit and went to use and did not work. hear a humming sound. took of fan blade end and turned the fan by hand.
removed the power side and all appears ok except the contactor inside that appears pitted. Any suggestions would be appreciated.

Thanks, I was asking about the knob. Clock wise - makes sense. This is the answer I needed.

Switch position on Speedaire 4Z705A
by: Bill

A bit confused about the question as I was not able to find an image that actually shows and ON/OFF switch, though I would think that if the compressor is plugged in, then flipping the switch left and right would quickly tell you which was ON, if the compressor works.

If your question pertains to the knob on the regulator that shows in the image, typically turning the knob clockwise will increase the output pressure and counter-clockwise will reduce the output pressure.
