Ice machine headmaster.

I dont deal with ice machines daily so its been awhile since i had a headmaster issue so i googled it and yes all hozi 404a units are 210 psi bypass looks like a headmaster issue to me wont get one this weekend but i have a condenser in the shop told my guy to go get a hotel and i will find someone to drive it over to him tomorrow 3 1 2 hours. The headmaster is necessary since the remote condenser is usually located outdoors in areas that will typical see a much colder ambient than the ice machine itself. This method is used in the harvest cycle to divert hot gas from the compressor to the evaporator grid to allow the ice to drop. In a remote ice machine there are several more components.

This headmaster kit is intended for use with scotsman remote condenser ice cubers and flakers. Could a headmaster cause the compressor to be frosted on an ice machine. Therefore ifthere was no headmaster the head pressure could drop low enough to prevent proper harvest or the refrigerant could store or isolate in the condenser. Originally thought maybe ice thickness control went bad but that wasnt the case.

If everything is everything and you add a little gas all of a sudden the suction will pop up to normal. Ice did not fall. On very cold days if the system charge is a bit low say 1 or 2 lbs the headmaster setting prevents enough gas from going to the evap showing like a 15 psi suction. When arrived evap was iced up.

Working on a manitowoc ice machine model ib1024yc. If headmaster replacement is necessary always use a replacement headmaster valve with the correct. Once i thawed out evap unit went into freeze formed ice and went into harvest. It was about 15 20f outside unit has remote condensing unit with headmaster and fan cycle control.

Ok here it is. First simplicity leads to reliability and second productivity is often times more important than features. An ice machine produces more ice in a 70 degree f room with 50 degree water than in a 90 degree room with 70 degree water. Could a headmaster cause the compressor to be frosted on an ice machine.

I was working on a scotsman ice machine remote nugget. The headmaster on some liebert s is set at 150. Some extra components often include. For more than 60 years ice o matic has designed and manufactured commercial ice machines storage bins and dispensers with two principles in mind.

Use the following list to check ice production. Pin to shift valve open or closed. The scotsman kpfhm headmaster kit works like other headmasters to regulate pressure between your ice machine and remote condenser. The headmaster pressure setting will vary depending on the system requirements.

Changed the compressor on it checked pressures and watched it make ice a bit and then left.
