detergent. Using the wrong detergent could cause flooding and/or damage your laboratory glassware washer. Do not use detergent that has been wet and is clumped. Also, check the expiration date on the container.

The amount of detergent needed can vary due to differences in water hardness. To determine the water hardness in your area, contact your local water utility or area water softening company. The harder the water, the more detergent you

may need. Refer to the chart below for the

recommended detergent amounts based on water hardness. Remember, you should adjust the amount of detergent you use by small amounts until you find the correct amount. Twelve grains and higher is extremely hard water and detergent alone may not be enough. You may need to use a water softener to maximize the performance of your laboratory glassware washer. Also, in areas with hard water (9+) you may need to wash at lower temperatures to prevent hard water deposits from forming in tank

Note!

Time remaining

the display indicates how long the program took the last time it was used. Once you have started the glassware washer, the display indicates how much program time remains. The remaining time is updated after the water for the final rinse has been heated.

This may differ somewhat from time to time depending on the temperature of the water

supply, the amount of glassware, and other

factors. While the program is running, the time counts

down and the remaining program time is shown on the display. The remaining time is shown, for example, as 1:15 which means the program will run for another 1 hour and 15 minutes.

During the first run of each program, the

remaining time displayed can be slightly

misleading, as the glassware washer is estimating the time. When you run the program a second time, the glassware washer will calculate the remaining time based on the previous duration of the program.

Top up with rinse aid

Top up with rinse aid as follows:

1. Open the rinse aid compartment lid.

The rinse aid dispenser can be adjusted between 0 (off) and 6.

Increase the rinse aid dosage:

 If the glassware has water marks.

Reduce the rinse aid dosage:

 If the glassware has a sticky white/blue film.  If the glassware is streaked.  Heavy foaming. If you have very soft water,

the rinse aid can be diluted 50:50 with water.

Set the dosage

The section Settings describes how to set the rinse aid dosage.

2. Carefully top up with rinse aid. Only add rinse
