Thank you for selecting Glastender, Inc. products.
What Is a GlassWasher?
Glastender, Inc. invented the world’s first 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 three-compartment sink. It “washes”, “rinses”, and “sanitizes” glassware.
note the sImplIcIty:
FunctIon desIGn

rInse and
sanItIze
Please read on to learn more about this simple machine.
Hot water and a preset portion of detergent join in the tank. During operation, hot soapy water is
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.
Fresh water and a preset portion of sanitizer and rinse aid join in the tank. During operation, rinse
water is pumped in a forceful, but gentle, spray pattern across the moving glassware. At the end
of the cycle, all water is drained so the next load can begin with fresh, clean water.

WARNING: The chemicals used in commercial glass washing 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 an accessory chemical storage drawer, part number 01001500.
1. Place chemical Feed Lines into the proper chemical containers.
Red - Detergent
Blue - Rinse Aid
Clear - Sanitizer
2. After utility connections described on page 2 are completed, plug in glasswasher.
3. Prime Chemical Pumps: Slide cover open to view chemical inlets.
Depress Prime switches to fill Feed Lines (see page 6 - Control Panel Operation).
Stop priming when chemicals come out of inlets.
NOTE: Always run a complete cycle or dump clean water in the tank after using the
prime switches. Undiluted chemicals will damage stainless steel.
4. Fill Level Adjustment: Cycle the glasswasher to check water fill level (water fill level
is preset at the factory but may require adjustments due to variations in water pressure/flow at installation location).
With the sliding cover open, initiate cycle by pressing Cycle Start (see page 6 - Control Panel Operation).
When fill is complete, verify that the water level is at the FILL mark (top of the drain screen handle - see photo
below).
If water level is correct, skip to Step 5.
If water level is above or below the fill mark, fill adjustment is required.
• Unplug glasswasher and remove front panel.
• Adjust the Fill adjustment knob on the circuit board. Turn knob clockwise to increase fill time or counterclockwise to decrease fill time.
• Leaving the sliding cover open will end the cycle and drain the tank after 30 seconds and cycle can be restarted to check water level again.
Once water level is correct, continue with Step 5.

5. Rinse Temperature Adjustment: With the sliding cover closed, initiate a cycle by pressing Cycle Start to check rinse
water temperature (Rin Temp knob is set fully open at the factory and may require adjustment at installation location).
Machine will perform wash cycle and proceed to rinse cycle. NOTE: Wash cycle water temperature must register
between 120°F (49°C) and 150°F (66°C). Adjust hot water supply source if necessary.
During rinse cycle (recirculating pump must be on to mix and stabilize temperature reading), observe digital temperature
read out. The sliding cover can also be opened, interrupting the rinse cycle to insert thermometer into the tank water.
NOTE: Minimum rinse temperature is 75°F (24°C) per FDA Ordinance and Code for Food Service Establishments,
Section 5-103(e)(2).
If the rinse water temperature is at desired temperature, skip to Step 6.
If the rinse water temperature is not correct, temperature adjustment is required.
• Unplug glasswasher and remove front panel.
• Adjust the Rin Temp knob counterclockwise to increase rinse temperature and clockwise to decrease the rinse
temperature. NOTE: The cold water inlet supply minimum temperature may exceed 75°F, resulting in the
inability to lower the water temperature further.
• Leaving the sliding cover open will end the cycle and drain the tank after 30 seconds and cycle can be restarted to check rinse temperature again.
Once rinse water temperature is correct, continue with Step 6.
6. Chemical Concentration Adustment: With the sliding cover closed, initiate a cycle by pressing Cycle Start to check
chemical settings.
The chemical strengths should be tested with a professional test kit by the chemical supplier. Water samples should be
taken during both the wash cycle and the rinse cycle.
Proper concentration levels:
Detergent - .30% concentration
Sanitizer - 50 PPM (sodium hypochlorite [bleach])
Rinse Aid - until proper sheeting is achieved
If chemical adjustment is correct, skip to Step 8.
Unplug glasswasher, remove front panel, and adjust chemicals on the circuit board as required.
Detergent: If the factory setting does not render the proper concentration, turn the Det 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 San adjustment knob clockwise
to increase or counterclockwise to decrease the dispense time. Repeat chemical testing procedure and adjust again if
necessary.
Rinse Aid: If the factory setting does not render the proper level of sheeting, turn the Rin Aid adjustment knob clockwise to increase or counterclockwise to decrease the dispense time. Run a test cycle to check wash results and adjust
again if necessary.
7. Replace panel and plug in glasswasher.
Repeat Step 6 to recheck chemical settings.
8. Your glasswasher is now ready for operation.

Important InFormatIon about chemIcals
The GW24 glasswasher has chemical pumps that automatically dispense chemicals into the machine. The detergent 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, understanding how the chemical
pumps work and how to maintain them is very important. Reviewing the following information 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 chemical 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 page 5, Step 6, 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. 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.
tIps For trouble-Free operatIon
1. NEVER, NEVER wash ash trays in the glasswasher. Since ashes are smaller than the opening in the Pump Inlet Screens, ashes can
adhere to glasses. Also, with ashes recirculating in the wash water, the cleaning effectiveness of the detergent is greatly reduced.
The final result of washing ash trays is dirty glasses.
2. For best results, run glasswasher full of glassware. This keeps the water and detergent consumption to a minimum and helps prevent glassware from tipping over.
3. Water spotting can occur when glassware is placed on a flat surface after washing, thus preventing air to assist the drying process. Make
sure the proper shelf liner or drying surface is used.
4. Clearance below the top cover of the glasswasher allows for a maximum glass height of ten (10) inches. Keep this in mind when
ordering beer pitchers and wine carafes.
5. Glasses which have been frequently washed by hand may have deposits of invisible “film”. Although initially appearing clean, these
glasses may show unsightly signs of “dirt” after passing through the glasswasher. This unsightly condition will exist until the film is
removed with frequent passes through the glasswasher, or it may be necessary to use a de-liming agent to clean glassware.
6. Do not place wet glasses into glass chillers or frosters. Allow glasses to dry and sanitizer odors to dissipate first.
7. Changing detergents may require readjustment of the Detergent Pump to maintain .30% detergent concentration. A greater volume of
low strength detergent is required to maintain the proper level.
8. Only Glastender, Inc. replacement parts should be used. Components from other suppliers may result in machine malfunctions.
Please consult your Glastender, Inc. service agent if service or technical assistance is required. The factory is also available to
answer any operational questions.

Warranty statement
APPLICABLE TO ALL PRODUCTS SOLD WITHIN THE UNITED STATES AND CANADA
LABOR: Glastender, Inc. warrants all products to be free of defects in
material and workmanship. In established areas, a start-up is included
with glasswasher models GT-24 and GT-30. A 1-year labor warranty
applies to all glasswashers. BDS model bottle disintegration systems
and self-contained refrigeration models, except beer line chillers,
include a 1-year labor warranty, for the duration of one year from date of
installation or up to 18 months from date of factory shipment, whichever
occurs sooner. For warranty labor claims beyond 15 months from the
date of factory shipment, proof of date of installation or occupancy must
be provided. Authorization for labor must be obtained from Glastender
within the warranty period and prior to the service being performed.
Labor warranty applies to the United States and Canada only.
PARTS: Within one year from date of installation or 18 months from
date of factory shipment, whichever occurs sooner, Glastender, Inc.
will replace any part or assembly found defective under normal use and
service. Field replacement parts include a warranty of 90 days from date
of installation.
FOUR YEAR ADDITIONAL COMPRESSOR WARRANTY:
Glastender will warrant to the original user the compressor for all selfcontained refrigeration models for an additional four years following the
regular one-year warranty period. This plan applies to the compressor
only.
A warranty claim form MUST accompany all returned defective parts or
assemblies. This form MUST be completed in full. Failure to do so may
result in delay or denial of credit. Any defective part or assembly must
be returned to Glastender, Inc., Saginaw, Michigan, with all transportation and delivery charges prepaid. Warranty repairs or replacements
will be shipped FOB factory in Saginaw, Michigan. Reimbursement for
applicable freight charges covers ground service only.
Glastender provides in-warranty repairs during a service company’s
regular working days and hours. There is no provision for payment
of a premium rate during “overtime” hours. When warranty service is
requested during other than normal working hours, the end user will be
charged the premium portion of the overtime rate.
The warranty covers substantiated travel expenses for up to 2 hours /
100 miles round trip and a maximum of $150. Any additional costs due
to installations that require extra work, time, or travel to gain access
for service are the sole responsibility of the equipment purchaser. Any
exceptions to these travel and access limitations must be pre-approved
by a factory representative.
The warranty does not cover equipment subjected to accidents, freight
damage, alterations from the original design, improper power and/or
plumbing hookups, improper chemical use, general misuse, or lack
of routine required maintenance as determined by Glastender, Inc.
Installation, normal control adjustments, general maintenance, correcting an installation error, or service calls that reveal the unit is functioning normally will not be reimbursed under warranty.
Condenser coils on self-contained refrigeration products must be
cleaned regularly. Failure to provide adequate air flow to a refrigeration
unit will void the warranty.
Glastender shall not be liable for loss of use, revenue, or profit, or for
any other indirect, incidental, special, or consequential damage including, but not limited to, product spoilage or loss.
This warranty is conditioned upon Glastender receiving notice of any
defect subject to this warranty within sixty (60) days of its discovery
by the end user or dealer. All products are warranted only for the initial
place of installation. Removal of a product automatically terminates
this warranty.
SECOND YEAR EXTENDED PARTS & LABOR WARRANTY:
Glastender’s one-year parts and labor warranty on self-contained refrigeration units, excluding beer line chillers, can be extended to two years
with the purchase of a two year parts and labor warranty. Specify part
number EWR2 ($150 net price) when ordering.
EXPORT WARRANTY - One year parts only.
EXCLUSION OF WARRANTIES
EXCEPT AS PROVIDED ABOVE, GLASTENDER MAKES
NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING,

LIMITATION OF REMEDIES AND DAMAGES

liability and Buyer’s remedies under this agreement will be limited solely
to labor charges authorized and/or replacement or credit, at Glastender’s
option, with respect to Products returned at Buyer’s expense within thirty (30) days after warranty repair. GLASTENDER’S LIABILITY WILL
IN NO EVENT BE GREATER IN AMOUNT THAN THE PURCHASE
PRICE OF THE RETURNED PRODUCTS. GLASTENDER
WILL NOT BE LIABLE UNDER ANY CIRCUMSTANCE FOR
CONSEQUENTIAL OR INCIDENTAL DAMAGES, INCLUDING,
BUT NOT LIMITED TO, LABOR COSTS EXCEPT AS COVERED
UNDER OUR WARRANTY, LOST PROFITS OR THE LOSS OF
PERISHABLE PRODUCTS RESULTING FROM THE USE OF OR
INABILITY TO USE OUR PRODUCTS OR FROM OUR PRODUCTS’

TO ANY THIRD PARTY, ARISING FROM ANY BREACH OF THIS
AGREEMENT.
