* Bunn model # for specific solutions.
* Most Pro/Office models have a pre-heated tank.
* Most models (Without Vacation or heater switch) will be heated all the time.
* Care must be taken to keep the inner tank filled.
* Pour cold water into fill tray till water comes out of the brew basket.
* Water will stop coming out of brewer once the tank has been topped off.
* If pot is not able to brew after 20 mins of pre-heating. Then call for service.
* Note; most office and Pro machines used in food establishments are from coffee vendors. The larger machines should be serviced by qualified Bunn service techs.
* Contact your coffee vendor or Bunn service ctr for advice.

If you have a 20 amp mains hookup, you will be fine.

Using vinegar is not a good idea. Use a proper coffee machine descaler. Run about 6 jugs of water through it with no coffee.

Are you sure the water passage is no plugged? Lime will build up and actually close it off .

Depends on your model. The smaller pour over units are easy as you prep your funnel with coffee as normal and get a full pot of hot water (just brew the water through the brew head and funnel to fill the pot.) If you have another pot or carafe, air pump pot. Then hold the coffee filled funnel (with coffee filter) over the empty pot and slowly pour the hot water over the coffee grounds. Go slow as you don't want to burn your other hand nor get grounds into the pot if you over fill the filter.
* If this is a 1-1/2 gallon brewer then the missing shower head won't mater that much as most of the 'flavor' is extracted in the first 1/2 gallon with the rest just filling the urn. If you do find the coffee to be weak then perform 3 separate 1/2 gallon brews to allow the grounds to fully soak and extract. Again, you can still do it manually as described above but it does get messy and very slow. (I've done this just to get something out to the customer. Well until I could get the repaired brewer up and running.)
* Most of the Bunn decanter brewers use a quarter size screw on spray head. No real substitute, though you could try a stiff sheet of aluminum foil to cover the coffee grounds in the funnel and poke holes into it. Though more than likely one of the waiters will dump it on the next brew.
* On one occasion (during lunch rush) I had to wait on a repaired urn to heat up but the waiter's needed coffee now! I took a pour over small brewer and made a pot with 1/2 gallon strength coffee and poured it into a larger urn then brewed more 'partial' batches till it was full. Hey, got to do what needed to get it out.
* You should always check with your coffee vendor as spray heads are very common parts and available at your local restaurant supply. There are other brands that use the same parts too like bloomfield. Ask around as this is a fairly cheap part.

The noise can occur when there is a heavy buildup of calcium on the heater coil. This causes the coil to get much hotter since the layer of calcium acts as an insulator and the water may come to a boil because the coil rises to a high temperature trying to heat the water.
Unless it is too clogged, this may help; empty the water out completely, then put two cups of regular vinegar in the water chamber and turn on the power for a half-minute or until liquid appears in the pot.
Let it sit overnight and then let the remaining vinegar pump through. You will have to run several pots of water through the machine or have some really strange-tasting coffee.
There are commercial products that act more quickly and thoroughly than vinegar but also much more caustic.
