Maintenance

ALL SERVICE MUST BE PERFORMED BY A QUALIFIED SERVICE TECHNICIAN.

This kettle requires very little preventative maintenance other than daily cleaning.

The pressure relief valve must be tested twice a year.

DANGER: Pressure relief valve will exhaust high temperature steam. Contact with skin could result in serious burns. Keep face, hands and body clear of discharge.

PRESSURE RELIEF

VALVE TESTING

PROCEDURE

The pressure relief valve must be checked at least twice a year as part of the normal maintenance performed.

1.With the kettle empty, fully open the steam valve and allow the kettle to preheat.

2.Stand to the side of the pressure relief valve discharge tube and pull valve open for a maximum of one second. Repeat test three to four times. Each time the mechanism should move freely and be accompanied by a rapid escape of steam.

⇒If valve appears to be sticking replace pressure relief valve.

⇒If foreign material is discharged then drain kettle and replace pressure relief valve.

WARNING: Improper refilling of kettle jacket will result in irreversible damage to unit.

STEAM TRAP

To remove line condensate that forms inside the steam jacket, each kettle should be equipped with a steam trap in the line of the kettle outlet to the drain. A good steam trap at startup releases air and wet steam into the drain line for a few minutes, then holds the steam jacket. During cooking, the trap periodically releases accumulated condensate. If the kettle's cooking performance becomes inadequate after long use, replacement of the steam trap with a new one may restore kettle operation to peak efficiency.

DRAW-OFF VALVE

To correct a leak at the draw-off valve, the source of the leak must first be determined, Leaks from around the valve stem are corrected by simply replacing the “O” ring. Faulty seating of the valve stem disc against the valve body may cause dripping from the valve even when the valve is tightly closed. This can often be corrected by cleaning any residue from the disc and seat.
