Page 9: Dishwashing Procedures
Dishwashing Procedures for best results Installation Read Operator manual. Correct installation, including an adequate supply of water at the correct temperature and pressure is essential for effective operation of your machine. Refer installation instructions for details. Water softening is recommended in hard water areas - especially for glasswashing. Pre-rinsing Pre-scraping of dishes is required by Food Hygiene Regulations. - Page 10 Dishwashing Procedures for best results Drying Single tank commercial dishwashers do not have a drying cycle. However, the machines do rinse at high temperatures which promote fast drying particularly when drying agents are used. We recommend prompt removal of the rack from the machine - leave the rack on the bench for 2 to 3 minutes before emptying.
