Re: kicking overloads but not consistantly
First: Most all compessors use check valves at the tank and an unloader to allow the compressor to start without a load. Make sure that system is unloading and that check valve is not leaking causing head pressure at start. Second: Too frequent starts and stops will cause motor to overheat. Check Quincy manual for max starts per hour. enjoy

Has this unit just been installed or has it been running. Just installed check wiring. If been running check wiring for tightness on starter. Check voltage and amps. Compare amp reading to overload heaters. They will have a # on them like E-58. Look in the starter box cover and there should be a chart showing the amp range for a E-58 or what ever size heater you have. If running amps are with in range shut down remove guard and belt. Rotate by hand the motor and pump. Any problems like looseness of shaft will indicate severe problems that may be causing the trip. Next if needed ohm out and meggar the motor. you should have found your problem by now!!
Hello, Ok, let's get the easy to check things out of the way first.
1) Is the tank empty? Take it out and weigh it on a bathroom scale. Most empty tanks weigh approx 18 lbs. The TW (tare weight) of your cylinder is stamped on the collar. If it weighs within a few lbs of your tare weight, then you simply need to refill it. Propane weighs 4.25 lbs/gal, so it would weigh approx 22 lbs with 1 gal of gas left.
2) Did you turn the tank valve on too fast? Close the tank valve, disconnect it and reconnect it. Then very slowly turn the tank valve back on. Try lighting the pilot and see if that helped. If not, try #3.
3) Your pilot orifice is dirty or has a spider web. Grab a can of compressed air (like you use to clean computer keyboards) and blow out the dust or web from the pilot assembly, which is where you light the pilot flame. Try lighting it and see if that solves it.
this unit should have a pressure switch that cuts the unit off and on with a adjustment to set the cut out .most switches have two adjustment screws.one of them tells the unit to kick on when the pressure is getting low.the other adjustment will raise the pressure to the desired amount.
The way I understand how Hoshizaki machines work, the model number is usually what the unit will produce, in pounds of ice.
Their manual states: "Approximate production/ 24 hours @ 70 degrees air/ 50 degrees water (incoming)"
So, yours should be producing 450 pounds a day, approimately.
Since I can not pin point your exact model, I found one that is close. It states: "Ice Production per cycle: 6.6 pounds, 360 pcs."
Again, it is not you exact machine. Their web site does not show this model either. So this is the best info I can get for you.
Hope this helps.
Check the reset button on the motor to see if it tripped. The motor may be overheating. Some motors have an internal breaker and they have to cool off before they restart. Also check the pressure switch. Move the switch back and forth ( on and off ) and listen for a click. If it doesn't click with low to no air pressure then the switch is bad.
