Important Safety Instructions • Read all instructions before using your laboratory dishwasher. • Use your laboratory dishwasher only as instructed in this Use and Care Manual. • This Manual does not cover every possible condition and situation that may occur. Use common sense and caution when installing, operating and maintaining any appliance. • LABORATORY DISHWASHER MUST BE ELECTRICALLYGROUNDED. Read the Installation Instructions for details.

Laboratory Dishwasher Features Your laboratory dishwasher cleans by spraying a mixture of hot water and detergent through the spray arms against soiled surfaces. First, the laboratory dishwasher fills with water covering the filter area. Water is then pumped through the filter and spray arms. Soil particles go down the drain as the water is pumped out and replaced with clean water. The number of water fills will vary with the cycle being used.

Operating Instructions Very Important Information—Read Before Operating Your Laboratory Dishwasher! Normal Operating Sounds This laboratory dishwasher does not sound like most laboratory dishwashers—IT'S QUIETER. Your laboratory dishwasher uses energy efficient motors for the wash and drain portions of the cycle you select. Each cycle has a series of water fills and drains for washing and rinsing labware. As each cycle begins, you may–or may not–hear the drain motor.

Operating Instructions Options Selections Hi-Temp Wash When HI-TEMP WASH option is selected the laboratory dishwasher adds temperature, time, and water to the cycle. The laboratory dishwasher heats water in the main wash to approximately 140°F (60°C). This increase in water temperature helps laboratory dishwasher detergent remove soil from labware more effectively and aids in drying. HI-TEMP WASH option can be used with all cycles except UPPER RACK, and RINSE ONLY.
PAGE 7
Preparing and Loading Labware Labware Preparation Upper Rack Option Scrape away large pieces. The continuous filtered wash system will remove remaining particles. The UPPER RACK option can be used to wash a wide assortment of items when you don't have a full load. Also, when the upper rack fills up with glassware and the lower rack is still empty, you don't have to wait anymore for clean glassware. Burned-on pieces should be loosened before loading.

Laboratory Dishwasher Dispenser and Detergents Filling the Detergent Dispenser How much Detergent to use The detergent dispenser has one main wash and one prewash cup. Detergent in the uncovered cup falls into the laboratory dishwasher when the door is closed. The covered cup opens automatically to release detergent. • Use only fresh automatic dishwashing detergent. Other detergents will cause oversudsing. • When using automatic dishwashing detergent tabs, place one tab in main wash cup and close.

Laboratory Dishwasher Dispenser and Detergents (Continued) Factors Affecting Performance Rinse Aid Water Pressure Rinse aid greatly improves drying and reduces water spots and filming. Water "sheets" off glassware rather than forming water droplets that cling and leave spots. The hot water line to the laboratory dishwasher must provide water pressure between 20 and 120 psi. A dispenser, located next to the detergent cup, automatically releases a measured amount of rinse aid during the last rinse.
PAGE 10
Care and Cleaning Care of Drain Air Gap If a drain air gap was installed for your built-in laboratory dishwasher, check to make sure it is clean so the laboratory dishwasher will drain properly. A drain air gap is usually mounted on countertop and can be inspected by removing the cover. This is not part of your laboratory dishwasher and is not covered by warranty. Outside—Occasionally wipe with a mild nonabrasive detergent and water. Rinse and dry.

Solutions to Common Problems Before calling for service, review this list. It may save you both time and expense. This list includes common experiences that are not the result of defective workmanship or material in your laboratory dishwasher. Soils Left on Labware • Choose another cycle for longer washing time. Glassware Spotted or Cloudy • Check water hardness. For extremely hard water, it may be necessary to install a water softener. (See Detergent Chart.) • Water temperature may be low.
PAGE 12
Solutions to Common Problems (Continued) Laboratory Dishware Stained or Discolored • Some solutions can cause items to become stained. Remove the stains by hand washing in a solution of ½ cup (120 ml) bleach and one quart (1 L) of warm water. Rinse thoroughly. • Iron deposits in water can cause a yellow or brown film. A special filter installed in the water supply line will correct this problem. (See Removing Spots and Film.) • Aluminum utensils can leave gray/black marks when they rub against other items.
PAGE 13
Solutions to Common Problems (Continued) Laboratory Dishwasher Does Not Drain Properly • If unit is hooked up to a food waste disposer, make sure the disposer is empty. • Check to see if the knockout plug has been removed from inside the food waste disposer inlet. • Check to see if drain hose is kinked. • Make sure cycle is complete, not in a pause.
