Instructions

3. Installation

3.1. Electrical*

A 15 Amp, 240 Volt, 60 Hz dedicated circuit should be used to supply electrical power to the GL-C machine (see

specification sheet page 2). The power connection with the leads L-1,L-2 and Ground must be such that there is

sufficient length of flexible conduit to permit the machine to be moved for cleaning. This machine operates from 208 to

240 Volts.

MODEL GL-C Installation & Operation Manual Rev. 1.00A –2/23/06 Page 4

3.2. Plumbing*

Hot Water Connection

1. Connect a minimum 1/2” water line to the hot water solenoid valve. Supply temperature must be minimum

140°F/60°C,with flow pressure between 25-95 PSI.

2. Hot water consumption is approximately 12 U.S. gph.

Cold Water Connection

1. Connect a minimum 1/2” water line to the cold water solenoid valve. Flow pressure must be between 25-95

PSI.

2. Open ball valve located between hot and cold solenoid valves until temperature reaches 75°F for areas with

very cold rinse water to heat the rinse water which will prevent glasses from cracking.

3. Cold water consumption is approximately 2.8 U.S. gpm.

Drain Connection

1. Connect a 1-1/2” drain line where indicated.

2. PVC pipe is generally recommended, as copper is prone to attack by the sanitizing chemicals.

*Electrical and plumbing connections must be made by a qualified

person who will comply with all available Federal, State, and Local

Health, Electrical, Plumbing and Safety codes.

Operation

5. Operation

5.1. Filling the Wash Tank

• Ensure that the overflow drain tube is in place in the detergent tank.

• Flip power on-off/flush switch to the “ON” position. The water will fill until the proper level is

reached then turn the heating element “ON”.

• The water temperature is controlled by a heater and a thermostat .The thermostat should be set

for minimum 140°F/60°C.

5.2. Operating Instructions

• Open the door; flip power on-off/flush switch to the “ON” position. Wash tank will automatically fill.

• Ensure there is product in the detergent, sanitizer and rinse agent containers.

• Detergent is fed from the supply container into the detergent tank in controlled amounts by the

detergent pump. Use detergent at strength recommended by your chemical supplier.

• Load glasses on the conveyor. Start machine with GL-C rocker switch located on front right side of

unit. Machine now will stop and start with conveyor shut-off rod.

3.2.1. Proper Chemical Dosage

The amount of chemical delivered, whether it is detergent, sanitizer or rinse aid, can be obtained by counting

the revolutions of the injector rotors.

• For detergent, contact your chemical supplier for proper type and detergent concentration.

Note: Detergent pump only operates when hot water tank is filling.

• For sanitizer, one revolution in 5 seconds equals approximately 12.5ppm Iodine or 50ppm

chlorine.

• For rinse agent, one revolution in 8 seconds is recommended.

To Adjust Detergent Injector:

• When a new detergent container is installed, push the prime button in and hold until the detergent feed tube is

full.

• Install the overflow drain tube and switch power on-off/flush switch to the “ON” position. The detergent feeder

will now feed detergent into the detergent tank with water fill.

• To increase detergent volume, turn the detergent adjustment screw clockwise.

• To decrease the detergent volume, turn the detergent adjustment screw counter-clockwise.

To Adjust Sanitizer Injector:

• When a new sanitizer container is installed, push the prime button in and hold until sanitizer feed tube is full.

• Start the washer with rocker switch located on the front of the machine. Take a sample from the final rinse

spray tube to check sanitizer level.

• To increase the volume of sanitizer, turn the adjustment screw clockwise.

• To decrease the volume of sanitizer, turn the adjustment screw counter-clockwise.

To turn rinse agent injector “OFF” in this case, turn the adjustment screw counter-clockwise until the pump

stops turning.

Note: If a sodium Hypochlorite (Chlorine) based sanitizer at a minimum concentration of 50ppm in the final

rinse is used, use chlorine test papers to verify and monitor the 50ppm chlorine level

MODEL GL-C Installation & Operation Manual Rev. 1.00A –2/23/06 Page 7

To Adjust Rinse Agent Injector:

• When a new rinse agent container is installed, push the prime button in and hold until the rinse

injector feed tube is full.

• Start the washer. Take a sample from the final rinse spray tubes.

• To increase the volume of rinse agent, turn the adjustment screw clockwise.

• To decrease the volume of rinse agent, turn the adjustment screw counter-clockwise.

Note:To meet the requirements of N.S.F. standards, Iodophor in a concentration of 12.5ppm

or chlorine at 50ppm must be used in the final rinse.

5.3. Cleaning Instructions

3.3.1. Daily Cleaning Instructions

Remove optional GL-C drain tray & waste collection, from the front of your glasswasher and clean.

Turn glasswasher off by flipping the power on-off/flush switch to the “OFF” position.

Remove right and left trays and GL-C curtain. Wash them with hot soapy water, rinse thoroughly, and

then dry.

Remove the conveyor as follows: Remove conveyor hub, flip conveyor shut-off rod to the side, lift

conveyor from the center and pull out.

Remove lower wash and rinse arms. Clean wash and rinse areas with hot soapy water. Rinse

thoroughly, and then dry.

Note: Do not twist spray arms, pull straight out or they will break.

Replace lower wash and rinse arms (they only fit one way). Replace conveyor as follows: With back

end of conveyor raised, mesh drive gear with side of conveyor, pull conveyor towards you until center

of conveyor drops onto pivot. Replace conveyor hub in center of conveyor, flip shut-off bar back to

normal position. Replace left tray ensuring shut-off arm rests within the retainer, then replace right

tray. Replace curtain.

Remove and clean upper and lower wash tank screens.

Remove overflow drain tube from the detergent tank, wash down the interior of the detergent tank.

Replace overflow drain tube and upper and lower wash tank screens.

Note: Do not leave water in tank overnight!!!

Replace optional GL-C drain tray & waste collection making sure hose is connected.

Ensure there is product in the detergent, sanitizer and rinse agent containers. Close the door.

3.3.2. Weekly Cleaning Instructions

Remove upper and lower wash and rinse arms from the manifold and clean spray tubes with Cleaning

Drill p/n 00899.01, Cleaning Brush p/n 00899.02 provided.

Remove detergent, sanitizer, and rinse agent feed lines from containers and place them in a

container of hot water. Hold prime buttons in until the feed lines have been thoroughly flushed.

Replace the feed lines to their proper container and prime product through lines.
