Component Shorts and Replacements
When replacing warmer elements, be sure the terminals on the relay are not too far up or down so that they do not contact the upper or lower part of the base. Contact will short them because of power going to the ground. When replacing warmer switches always be sure the Number 3 on the lighted rocker is at the top of the switch when placing in the hole. The top lead will be silver, the second lead will be silver and the third will be gold. When connecting the wires, always remember:
Number 3 (Silver at the Top) should connect with a white, neutral wire.
Number 2 (Second silver lead) should always connect with a black power in wire.
Number 1 (Gold bottom lead) should connect to a black or colored power out wire.
The bottom (Gold) lead will go to what you want to run; for instance, the warmer element or power to run a start switch, etc.
GFI (Ground Fault Interrupter)
The most common culprit on the GFI (Ground Fault Interrupter) is moisture on the warming plate. The customer spills coffee or water heavy enough to get moisture in-between the element and plate. You need a meter to read the components to see if there is a bad one. But usually all you need to do is let them dry out, they should be ok when you plug back into the GFI. As it turns out, most of the problems relating to shorts and wiring happen after replacing warmer switches, warmer elements or when using a GFI.
It is very important to sanitize all your tea equipment. To avoid bacterial contamination and growth, tea brewing and storage equipment should be sanitized once a day. Dismantle dispensing spigots (faucets), hoses, bonnets, gaskets, o-rings and remove urn, rinse them in warm water (110-120 F) with detergent. You can also sanitize the parts by rinsing them in warm water at 75 F with chlorine at 50 parts per million (ppm). You can also use iodine in hot water at 14 ppm or use ammonium compound at 100 ppm. Just remember the most important point about tea brewing is to sanitize your equipment every day.
Automatic Brewing Installation Tips
When new equipment is installed on existing water lines, or lines are put on existing self-piercing water valves, a volume test must be performed to see what the line can produce. The water line should produce a half-gallon of water in 30 seconds or less. If you can’t supply that amount of water you will probably get calls from your customer because of an over-flow at times. You may have to keep adjusting the timer, timers go by the amount of water in the pot. Instead of how long the timer ran.
Most brewers are simple machines. They have a flow-control, valve and timer. The only real requirements are a good water supply, and that the lines need to be purged after they are put in and before hooking up. Next time you saddle a valve, consider teeing off the main water line. Self-piercing saddle valves are a major cause of equipment problems in the OCS industry. When the volume is not tested, more than 60% of the installations result in a phone call that blames the equipment for short or long pots.
Anything that must be returned for replacement or warranty must be accompanied with an RA#. You can get an RA# by contacting your customer service representative or any of our technical service representatives. You will need to have the following information ready:
- Model Description
- Serial #
- Date Purchased
- Invoice #
- Reason why you are sending it back
This system allows us to track your return, correct possible problems, and credit your account.
On Location Repair
- Call us with the symptoms before going on location.
- Keep cotton swabs and a small bottle of mineral oil in your tool kit. This is to lubricate the faucet shaft.
- Carry a 2 to 5 gallon bucket. Every time a shutoff valve is shut down, it should be purged before hooking back up. EVERY TIME. The bucket is in case you need to empty a machine.
- A T-100 or X-2 stove is also helpful. If you are going to be a while, make coffee before working on the equipment.
- Thread tape is a real must.
- Four feet of 1/4 inch flexible tube can be used to siphon the water into your bucket, or if your running a machine that has the fill tube exposed, you can slide the tubing over the fill tube, and put it directly into a pot to check water levels, or pre-set timers with out going through the tank.
- Clean and polish your brewers.
