For proper operation, use non-foaming detergents and buffered sanitizer. Do not wash gold, pewter, silver, or silver-plate with chlorine based sanitizers. High concentrations of chlorine sanitizers and caustic detergents will cause damage to metals and welds. Do not exceed 50 parts-per-million (PPM) “free” or available chlorine. Any setting higher than 50 ppm will be dependent on local health requirements, however, the increased chlorine will result in higher corrosion of metal parts.

If this vapor lock occurs, check incoming water temperature and reduce the temperature if it is above 140- 150°F. Operating temperature of 120°F is the minimum, 130-140°F is recommended. If the problem is caused by low water pressure to the machine, then see the Plumbing Section above to correct that condition. - Page 13 Drain ball assembly and pump fi lter Optional ET (Gravity) secondary fi lter #085-6616 8 PUMP FILTER—Inspect the sump area and verify pump fi lter is in place.
