7.0 CLEANING INSTRUCTIONS (Continued)
NOTICE: Draw-off valve has a vulcanized rubber coated stem for better
sealing. Do not over tighten. This may cause the rubber to pull away from
stem and permanently damage it. This is not covered under warranty.
DRAW-OFF VALVE CLEANING
1. If equipped with a tangent draw-off valve, turn the large hex nut on the draw-off valve
counterclockwise until it is completely disengaged from the threads. Grasp the valve knob
and slowly pull out the valve stem. Wash the valve stem, disk and handle. Insert a nylon
brush, wet with detergent and water, into the valve body and tangent draw-off tube. Brush
vigorously.
2. Replace the valve stem assembly and turn the hex nut until snug. Rinse the kettle with
clean warm water.
3. Leave the draw-off valve open when the kettle is not in use.
DAIRY DRAW-OFF VALVE CLEANING
1. Remove the plug by first removing the handle, then turn the plug to line up with the pin and
pull with both hands. It is important to use both hands because the plug is heavy.
2. Put the plug in a plastic pail that contains a mild soap solution. A plastic pail works best, as
it reduces the possibility of nicking or scratching the plug. If the plug gets scratched it may
not seal correctly and could leak.
3. Use a soft cloth or soft brush and clean all surfaces.
4. Using both hands remove the valve from the soap and rinse well in another plastic pail that
contains fresh water.
5. Wash out the kettle as normal.
6. Return the plug into the body. Be sure the plug is inserted into the notch and turned.
Ensure the plug is tight and secure before letting go of it.
If you are cleaning a body and plug assembly, remove the plug and follow the above
procedures. When finished with the plug, follow the same instructions for washing the body.
Always use both hands when handling the plugs. Reassemble the plug into the body and use
as normal.
