Below are step-by-step instructions to help you

achieve the best possible laboratory glassware

washing results.

Load the baskets correctly

Do not rinse labware under running water

before loading them in the laboratory

glassware washer. Simply scrape off large

particles before loading the laboratory glassware

washer.

Washing

Note!

and wash system. In hard water areas, both the

labware and the machine can develop a white or

gray film after a while. If this happens, run the

Heavy program with high temperature and two

tablespoons of citric acid or commercially

available “dishwasher cleaner”in the detergent

compartment (with no labware in the machine).

1

We recommend that you do not add prewash

detergent for the programs Quick or Super Quick.

Note!

If you use a detergent with a rinse aid additive,

you should not fill the rinse aid dispenser.

This could cause a film on your labware.

Note!

All dirty surfaces should face in and down!

Check that the spray arms can

rotate freely

Add detergent

We recommend that you use only

unscented, low sudsing granular

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

3

Liquid hand-washing detergent must not be used

as the foam that forms prevents the laboratory

glassware washer from operating effectively.

Detergent Tablets

Halve the tablet if it is difficult to close the

dispenser lid. There is a risk that the detergent

will not be released properly if the lid is tight and

cannot open correctly.

Detergent tablets are not recommended for short

programs (less than 75 minutes). Use powder or

liquid detergent instead.

3-in-1/ All-in-one detergent

Read through the directions for these products

carefully. If anything is unclear, contact the

detergent manufacturer.

remaining time to indicate that the

program has started. Close the door properly,

otherwise the glassware washer will not start.

The display indicates if the door is open.

If the machine does not start within 2 minutes of

the last button press, the display returns to

showing the last program run.

Stopping or changing a program

If you want to change programs after starting the

glassware washer, open the door then press and

hold Start/Stop for five seconds. Add more

detergent if the lid of the detergent dispenser has

opened. Then choose a new program, press

Start/Stop, and close the door.

Do you want to add more glassware?

Open the door. The glassware washer stops

automatically. Add the glassware, close the door,

and the glassware washer resumes the program.

Select options

To select an option, press one of the

option buttons. The field next to the button

lights when the option is activated. The

available options depend on the selected

program. Once you have started the program, the

options you selected are saved for the next time

you use the same program. An exception is the

Delayed start option.

High temperature

Activate this option for improved glassware

washing results. The machine then uses a higher

temperature for the main wash.

If you want to use the lower temperature, press

until the field next to the button turns off.

You can vary the temperature as shown below:

Long dry

A higher temperature in the final rinse and a

longer drying phase improves the drying result if

you activate the Long dry option. This causes a

slight increase in energy consumption.

If you want to use the lower temperature, press

until the field next to the button turns off.

Settings (continued)

The glassware washer uses a buzzer

to indicate when a program is

finished or when a fault has occurred.

6210 Campbell Drive. Madison, Ohio 44057-2003 | Phone: 440-428-7800 | Fax: 440-428-8650 Page 17

Time remaining

Once you have selected a program and options,

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.
