IntroductIon
This manual describes the operational features of the GT-24 and GT-30 model glasswashers with digital temperature gauges. Please review this information before attempting installation and operation.
Long-term, trouble-free operation will follow if good housekeeping and maintenance procedures are followed.
Thank you for selecting Glastender, Inc. products.
what Is a Glasswasher?
Glastender, Inc. manufactured the original automatic rotary glasswasher in 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 threecompartment sink. It “washes”, “rinses”, and “sanitizes” glassware.
note the sImplIcIty:
FunctIon desIGn
wash Hot water and a preset portion of detergent join in the Wash Tank. Operating temperature
is maintained between 130ºF (54ºC) and 150ºF (66ºC) by a stainless steel heater, and the
proper water level is maintained with a liquid level control. During operation, 5 gallons
per minute of hot soapy water are pumped in a forceful, but gentle, spray pattern across
the moving glassware. This entire wash compartment is isolated by curtains, and the
wash water is recirculated to conserve water and detergent. Actual hot water consumption
during operation is ¼ gallon per minute.

Please read on to learn more about this simple machine.
Cold water and a preset portion of sanitizer join in the sanitizing compartment called the
Rinse Tank. The proper water level is maintained with a liquid level control. During
operation, 2 gallons per minute of cold rinse water are pumped in a forceful, but gentle,
spray pattern across the moving glassware and down the drain. The unique pumped rinse
feature ensures a consistent, thorough rinse.
