Daily — Kettle Food Draw-Off Valve

CAUTION: During disassembly, cleaning and reassembly of the valve, take special care to avoid damage to the mating surfaces of the valve plug and valve body. Do not allow the valve plug to contact metal or hard surfaces during cleaning. Do not use metal utensils or scouring pads to clean the valve's mating surfaces. Do not drop valve plug. Damage to the mating surfaces will result in a leaky valve. Damaged valves are not covered under warranty.

1.Disassemble and clean valve daily. With kettle empty, turn valve handle to the *removable position. Lift valve plug from valve body. A pin locks the valve plug into the valve body; the valve plug can only be removed or replaced when the valve handle is at the *removable position. Do not attempt to slide the valve plug into the valve body when the valve handle is in any other than the *removable position. This would damage the pin, cause the plug not to seat properly and cause leakage between the valve plug and the valve body.

* The removable position for valves manufactured after June 2003 is with the handle positioned at 7 o'clock. The removable position for valves manufactured from March 1992 through June 2003 is with the handle positioned at 4 o'clock. The removable position for valves manufactured prior to March 1992 is with the handle positioned at 6 o'clock.

2.Using a solution of warm water and detergent, wash the entire valve body the opening that goes into the kettle interior. Also wash the interior and exterior of the valve plug.

3.After cleaning the valve, lubricate the valve body and valve plug with Petro-Gel lubricant supplied with kettle. Make sure all interior mating surfaces are covered with this lubricant before sliding the valve plug into the valve body. Make sure the valve plug handle is in the *removable position when the plug is slipped carefully into the valve body.

A 4 oz. tube of Petro-Gel lubricant, (P/N 833652) is furnished with your kettle. You can reorder through your local service agency or food service equipment dealer. There are no substitutes for this lubricant. If you fail to lubricate the valve body and plug after cleaning or use a substitute lubricant, this could damage the mating surfaces which is not covered under warranty.

4.If multiple kettles are in use, each draw-off valve body and draw-off plug is stamped with a set of corresponding numbers. After cleaning and lubricating, make sure the body and plug numbers match before reinserting the valve plug. Always examine the valve plug and valve body for nicks and heavy scratches. Do not push or force the valve plug into the valve body if there are any obstructions, nicks or heavy scratches in either the plug or the valve body.

5.To correct a draw-off valve that is leaking after lubricant has been applied, examine the mating surfaces of the valve body and valve plug and carefully dress any raised places with a very fine file or emery cloth. Do not cut below metal surface in removing any raised places. Coat plug lightly with lapping compound, insert plug into valve body and rotate back and forth several times to seat plug into valve body. Use medium grade lapping compound first and finish with a fine grade. Valve grinding compound from an automobile supply house is suitable for this. After use of lapping compound, clean surfaces thoroughly. Lubricate surfaces with Petro-Gel lubricant. If the valve still leaks after lapping, repeat the lapping procedure.
