6.0TROUBLESHOOTING MAINTENANCE

PREVENTIVE MAINTENANCE

No preventive maintenance is required other than adhering to the Cleaning Procedure instructions.

DRAW-OFF VALVE LEAKS

If a leak occurs through the valve stem, replace the “O” ring.

If the leak can be attributed to faulty sealing occurring between the stem disc and valve seat, then this problem may be corrected by cleaning off the dried-on food residue with extremely fine emery cloth. If the vulcanized rubber stem piece has been damaged, it must be replaced.

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 CAUSE PERMANENT DAMAGE.

EXTREMELY SLOW COOKING TIME

If the cooking time is abnormally slow, this may be due to insufficient steam pressure and/or volume. First determine that pressure on incoming steam line at kettle is within 5 p.s.i. of rated kettle pressure. Note that pressures approaching the rated kettle pressure are liable to set off the safety relief valve. If required pressure is available to kettle, then possibly volume of steam is not sufficient. Minimum 3/4" pipe size is required to the kettle but if the steam generating source is at a great distance from the kettle, larger supply pipe will be required. Finally, the core of the steam supply pipe may have debris or scalants that impede steam flow and will require disassembly and inspection.
