Start-Up Instructions 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. Remove Drain Plugs allowing tanks to drain. Adjust Detergent and Sanitizer Pumps. (See pages 9-10) Replace Drain Plugs. Turn Fill Switch to “on” position. The Wash and Rinse Tanks should now fill near the top of the overflow walls. When the Wash Tank is full, the thermostatically controlled Heater will turn on and off as necessary to maintain the water temperature at approximately 150° F. NOTE: The Thermostat is preset at the factory.

Useful Information About Water, Detergent, and Sanitizer Water Conditions Your water supply fits one of the following descriptions. Greater detergent consumption is required with “hard” water. Description Soft Slightly Hard Moderately Hard Hard Very Hard Grains Per Gallon Less than 1.0 1.0 to 3.5 3.5 to 7.0 7.0 to 10.5 10.5 and over Parts Per Million Less than 17.1 17.
How to Operate the Glasswasher The automatic rotary conveyor glasswasher is designed to “wash, rinse, and sanitize” hundreds of glasses per hour. The rotating conveyor automatically moves glassware through the three operations. Since the machine is typically dis-assembled for cleaning at the end of each day, start each day by ensuring that the machine was properly re-assembled after the previous day’s use. Once re-assembly is complete, press the fill switch to fill the wash and rinse tanks with water.
How the Glasswasher Operates (Continued) The chemical pumps have chemical feed lines that are attached to a chemical low-level sensor pick-up tube. One set of lines is labeled for detergent and the other for sanitizer. Both set Low-Level Sensor Pick-Up Tube of lines must be placed inside the appropriate Chemical Feed Line chemical container. The purpose of the chemical low-level sensor pick-up tube is to make the low-level chemical light flash when the chemicals get low.
How the Glasswasher Operates (Continued) What are the Prime Switches? Chemical pumps have a speed control so they can be made to run faster or slower (see pages 9-10). Chemical vendors adjust the amount of chemicals that get inserted into a tank of water by altering the speed of the chemical pump. The water inlet valve only takes a certain amount of time to fill the tank.
Important Information About Chemicals The GT-24 and GT-30 glasswashers have 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.
Diagnosing Poor Wash Results The best way to understand why you are getting poor results is to know what components belong in your machine and how they are supposed to operate. If you are getting poor results from your GT-24 or GT-30 glasswasher, follow these simple steps to help diagnose your problem. Possible Cause Remedy 1. The machine is dirty and/or the spray box holes are clogged. The machine may require de-liming, because of excess water deposit build-up. 1. Clean and/or de-lime the machine. 2.
Cleaning Instructions The following cleaning instructions are recommended. Operating procedures of an establishment may alter the time of cleaning and the personnel assigned to cleaning. At the close of business, and after all glasses have been washed and unloaded, turn the Conveyor Switch and the Fill Switch to the “off” position. No other attention is required until the next morning. In the morning, the bartender should follow the recommended cleaning instructions.
