Important Information About Chemicals The GT-18 glasswasher has chemical pumps that automatically dispense chemicals into the machine. The detergent and sanitizer chemicals are supplied by a chemical vendor. Since the type of chemicals and the condition of water varies by region, the chemical pumps are not pre-set at the factory. The chemical pumps must be adjusted at start-up to achieve the proper titration levels or the machine may not produce good wash results.
Tips for Trouble-Free Operation 1. NEVER, NEVER wash ash trays in the glasswasher. Since ashes are smaller than the opening in the Pump Inlet Screens, ashes, could adhere to glasses. Also, with ashes recirculating in the wash water, the cleaning effectiveness of the detergent is greatly reduced. The final result of washing ash trays is dirty glasses. 2. For best results, run glasswasher full of glassware. This keeps the water and detergent consumption to a minimum. 3.
