whaT iS a GlaSSwaSher?

Glastender, Inc. has been manufacturing automatic glasswashers since 1969. Today, Glastender glasswashers
have been installed around the world. But what is a glasswasher? It is simply a piece of machinery that washes
glassware, which eliminates the need for human labor and the conventional three-compartment sink. The glass­washer is, in effect, a mechanized three-compartment sink. It “washes”, “rinses”, and “sanitizes” glassware.

noTe The SimpliciTy:

waSh 120ºF (48.9ºC) water and a preset portion of detergent join in the tank. During operation, 5 gal-

lons per minute of hot soapy water are pumped in a forceful, but gentle, spray pattern across the
moving glassware. When the wash cycle is complete, all water is drained. While the drain is still
open, clean water pre-rinses the holding tank to prepare for the rinse and sanitize cycle.

the moving glassware. At the end of the cycle, all water is drained so the next load can begin with
fresh, clean water.

2. Place chemical Feed Lines into the proper chemical containers.
a. Red is detergent.
b. Blue is rinse aid.
c. Clear is sanitizer.
WARNING: The chemicals used in commercial glasswashing are very harsh. Exposure to human skin can

cause severe burns. Chemical containers should be stored in a manner and/or location that pre­vents them from spilling or splashing. Chemical containers must be secured. Please consult your
chemical vendor to ensure proper storage or call the Glastender factory to purchase a clip-on
chemical rail, part number 01000710.

3. After utility connections described above are completed, plug in glasswasher.

4. Depress Prime switches to fill Feed Lines. NOTE: Always cycle the machine after using the prime switch­es. Undiluted chemicals will damage stainless steel.

5. Cycle the glasswasher and check chemical settings.

6. If chemical adjustment is required, unplug glasswasher, remove front panel, and adjust chemicals as required

using the Electronic Control Timer. See chemical adjustment procedure below.

chemical adjuSTmenT procedure

The chemical strengths should be tested with a professional test kit by
the chemical supplier. Water samples should be taken during the wash
cycle and the rinse cycle.

Detergent - .30% concentration
Sanitizer - 50 PPM (sodium hypochlorite [bleach])
Rinse Aid - until proper sheeting is achieved

Detergent: If the factory setting does not render the proper concentration,

turn the detergent adjustment knob clockwise to increase or
counterclockwise to decrease the dispense time. Repeat chemi­cal testing procedure and adjust again if necessary.

Sanitizer: If the factory setting does not render the proper concentration,

turn the sanitizer adjustment knob clockwise to increase or
counterclockwise to decrease the dispense time. Repeat chemi­cal testing procedure and adjust again if necessary.
