Important Information About Chemicals - Glastender GT-18 Operation Manual

mporTanT
The GT-18 glasswasher has chemical pumps that automatically dispense chemicals into the machine. The deter-
gent and sanitizer chemicals are supplied by a chemical vendor. Since the type of chemicals and the condition of
water varies by region, the chemical pumps are not pre-set at the factory. The chemical pumps must be adjusted
at start-up to achieve the proper titration levels or the machine may not produce good wash results. Typically,
the chemical vendor is responsible for adjusting the chemical pumps.
Since detergent and sanitizer chemicals play an important role in the performance of a glasswasher, understand-
ing how the chemical pumps work and how to maintain them is very important. Reviewing the following infor-
mation will help ensure the proper operation of your glasswasher and its chemical pumps:
1. CAUTION: Always cycle the machine after using the prime switches to rinse out the wash/rinse tank.
Undiluted chemicals will damage stainless steel.
2. The chemical feed lines must be properly placed inside the appropriate chemical container. Damaged chemi-
cal lines will spill chemicals on the machine and floor and create poor wash results.
3. Every glasswasher requires chemical pump adjustment and titrating by a chemical vendor. Poor wash results
will occur if the chemicals are not in proper concentration (see the operation manual for proper concentration
levels).
4. Glasswasher chemicals are highly caustic and will cause severe burns when they contact human skin. These
same caustic chemicals will also corrode stainless steel and destroy machine components. A glasswasher
should be checked regularly for chemical leaks and any leaks should be corrected immediately.
5. All of the chemical tubing on a glasswasher should be inspected regularly and replaced at least once per year.
The highly caustic chemicals cause the chemical tubing to get brittle, and since leaking chemicals destroy
glasswasher components, it is good preventative maintenance to replace chemical tubing often. The various
tubing includes the lower tubing assembly or main chemical feed line, the pump squeeze tube (especially
susceptible to damage), and the upper tubing assembly from the pump to the glasswasher tank.
6. Chemical vendors that deliver chemicals to your establishment are typically responsible for adjusting the
chemical levels in your glasswasher. They are also helpful for assisting you with chemical tubing inspection
and replacement. Nothing removes your responsibility for proper maintenance, but the chemical vendor will
help.
