VSP 2018 Operations Manual

13.16.1.2.2 Mercury Spills
Use mercury-filled maximum registering TEMPERATURE-
MEASURING DEVICES carefully during the evaluations; these
devices are subject to breakage. If they break, clean up thoroughly
before WAREWASHING operations resume.

13.16.2 Machines Data Plates

13.16.2.1 Data Plate Required

Review the required manufacturer’s data plate for correct operating
parameters.
• If the data plate indicates a flow pressure, the machine must have a
gauge or a gauge valve to measure it.
• If the data plate does not indicate a flow pressure, the machine is
not required to have a gauge or a gauge valve.

13.16.2.2 Temperature Requirements
Temperatures stated on the warewash machine data plate are considered
minimums unless a specified range is given.

13.16.2.3 Conform to ANSI/NSF 3-1996
The warewash machine temperatures must conform to those specified in
these guidelines for the specific type of machine. For those manufactured
to different temperature standards, evidence must be furnished that they at
least conform to the minimum equivalent standards of ANSI/NSF 3-2008,
Commercial Spray-type Dishwashing and Glasswashing Machines.

13.16.3 Evaluation Procedures

13.16.3.1 Operational Evaluation
The VSP EHO will evaluate the WAREWASHING as follows:
• Dishes properly prescraped and racked.
• Machine prewash scrap trays clear of excessive soil and debris.
• Curtains and baffles on conveyor type machines intact and in their
proper position.
• Conveyor speed and cycle times set according to manufacturer’s
specifications.
• Overflow standpipe installed and not blocked or leaking.
• Wash and rinse nozzles properly aligned and providing a uniform
spray pattern.
• Wash and rinse nozzles clear of obstructions.
• Wash and rinse manifolds in good repair, properly installed in the
machine, and end caps installed.
• Heating elements used in tanks free of mineral or other deposits.
• Rinse supply line strainer clear of debris.
