Bunn, DUAL brewers are large volume (1-1/2 gal per thermal Dispencer.) In most commercial VAN operations there is a requirement to cook and assemble food in a sanitary food approved kitchen or process plant. Brewing would be done at the kitchen. To use this type of brewer would be to get enough 1-1/2 gal servers to cover your needs for the event. Brew everything you need in the morning and just take the servers to the event. I remember waking up at 4 AM to brew 25 servers for big events. We even did a mid morning run with another 15 servers. You can also install low wattage warmers designed for the servers. I suggest two warmers to keep regular and de-cafe hot. The rest can be set aside. Some servers will stay hot enough for up to 4 hours. * Installing the brewer in the van has problems with keeping the water level. You will need a "Boat kit" to allow for sloshing water. You also need a pressurized water tap. Power is rated at 220-240 30 amps. (40 amps if your at 200VAC) * Check with your local coffee vendor for advice. Aloha, ukeboy57

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. Aloha, ukeboy57

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.

You should call your vendor for service. *** the following is for information only *** * Lime build up is caused by heated water standing and cooling off or drying out as it stands. * Daily wipe down of equipment and removal of standing water puddles help minimize this build up. * washing pots daily will remove coffee stains and prevent build up. * Do not allow pots with coffee or water to sit overnite on warmer plate. * Internal lime requires a qualified tech to disassemble equip to service. * check bunn.com for free download of manual and cleaning instructions.

Service should be performed by a qualified tech.*** * Most Bunn grinders usually have an adjustment screw in the middle of the burr plate housing. * LPG is under the bottom chute. It's hard to see and you may need a mirror. Take a stubby flat blade screw driver in the slot and turn as needed, but go a quarter turn at a time! * G2/3 have a large dial with the grind sizes clearly marked out. There is an adjust/calibration screw in the center of the knob. * G9 have a large bolt in the center of the burr with a slot that could fit a quarter coin in it. You must un tighten the locking nut to turn it. Make sure you lock it down again after the adjustment. * Final; if there any loud noise or grinding metal sounds or the motor hums and stops. Then turn off grinder right away. Back off whatever you did last and try again. If it's still making noises then unplug and call your vendor for service. Aloha, ukeboy57

* Check bunn.com for a free download of manual for this brewer. * If this is a pour over (VPR, VPS, etc.) then you must pre fill it then pour in one pot of water to get one pot of brewing hot water out of it. * If this has an external tank of water then it must be filled and make sure the float sensor works and pops up to indicate a filled tank. * But most likely this is a CWTF, CW, or larger commercial brewer that has a plumbed in water line. If this is the case then the tank must be pre-filled and heater turned on. (a switch in the back) Installation is usually done by the vendor or service tech. It should have been tested and brewed to check water level of brew. Follow the brewing instructions. * Still not working? Call vendor for service. It could be timer, brew switch, water level board, water fill valve,brew valve. all need check and service to replace as needed. Many larger units have high voltages so call the tech to be safe.
