Grundfos freshwater systems pump guide

Grundfos Product guide

Grundfos install and operating instructions

The Grundos MQ pump is compact and extremely easy to install. The pressure switch and tank are already built into the MQ. Furthermore, it is self priming and water cooled with a very low noise level. The outlet pipe connection can be angled up to 5ยบ to fit your existing pipe-work.

Grundfos' MQ pump is simple and easy to operate. The settings are clearly indicated on the user friendly control panel with indicator lights for Pump on/off, auto reset, and an alarm indicating dry running or overheating.

Grundfos MQ is built for trouble free operation. It's construction from corrosion resistant materials means it can be used for clean water. The anti-cycling feature prevents the pump from repeatedly starting and stopping in the event of a dripping tap or a minor leak. If there is no water available, the pump will stop to protect itself and restart automatically when water is available again.

Ice Machine 101

An ice machine is a great thing to have around. Having tons of fresh ice is always a plus here in the swamp. An ice machine is a dedicated contraption for doing one thing good. That is making ice cubes. How? Manufacturers have cleverly devised a way to make ice. They use a pump to circulate water over an evaporator plate with dimples. As the water pours over the plate ice cubes begin to form. When the thickness is ok the machine diverts the high side discharge gas into the plate and this loosens the ice cubes. They drop down into the bin. The ice maker does a little dance and kicks back in to start another batch. When the bin get full a simple mercury probe opens the power circuit, killing the production until the need again arises. As long as ice is touching that probe she is dead in the water resting and getting ready. When that ice is gone the probe powers up the machine to get at that ice production again. The End.
Not so fast Mr "So what can go wrong"!!! What does go wrong on these machine? Dust builds up in the condenser making the ice production suffer. From time to time Ice machine cleaner must be applied to the machine to clean up the plates. Fan motors go out. Water pumps too. Controls go haywire and the whole shebang can get a big fat freon leak which kills ice production. One thing you may not know is: Ice machines are very fickle. They don't dance when ordered to . Everything gotta be alright fer that heifer to dump ice cubes. You go monkeying with the freon charge in an ice machine and you has troubles. You must ALWAYS add in the correct amount of freon. Very critical. That's all of the smart pills for today folks.

Window unit blows air but compressor does not work

Look for a swollen failed capacitor.
Check wiring on compressor for broken terminal connector.
Check compressor overload for continuity
