Operation

 

3. Installation 

 

3.1. Electrical

*

 

 

A 20 Amp, 208-240 Volt, 60 Hz dedicated circuit should be used to supply electrical power to the GL-C machine (see 
specification sheet page 3). 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 SERVICE & PARTS MANUAL Rev. 1.02 –6/27/07                                                                                                             

Page 

 

                                                                                                                                                             

    

                                 

   

                                    

 

 

 

Note: For cord-connected machines provide a grounding receptacle NEMA Type 6-20R. 

3.2. Plumbing

*

 

             

Making Cold Water Connection 

1.  Connect a cold 1/2” water line to the cold water solenoid valve and inspect for leaks. Water flow pressure 

should be between 20-100 PSI. 

2.  Cold water usage is approximately 2.8 U.S. gpm. 

3.  Machine is equipped with a mixing valve located between hot and cold solenoid valves. Open until 

temperature reaches 75

°

F for areas with very cold rinse water to heat the rinse water which will prevent 

glasses from cracking. 

 

Making Hot Water Connection

 

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

140

°

F/60

°

C,with flow pressure between 20-100 PSI. 

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

 

Making Drain Connection

 

1.  Connect a 1-1/2” PVC drain line to the bottom of the scrap tank. (note: machine is gravity drain)  

                                                      

*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

 

4. Operation 

4.1. 

Filling of the Wash Tank 

• 

With overflow drain tube in place in the detergent tank proceed to following. 

• 

Turn power on-off/flush switch to the “ON” position. The water solenoid will activate and fill soap 
tank until the proper level is reached, also activating heating element. 

• 

Set the thermostat for minimum 140

°

F/60

°

C. The wash tank temperature is regulated by heater 

and thermostat. 

4.2. Operation 

Instructions 

• 

Open the door; place on-off/flush switch to the “ON” position. The wash tank will begin its 
automatic fill cycle.  

• 

Verify product containers have chemicals.  

• 

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. 

• 

Place glasses on the conveyor wheel. Push conveyor rocker switch located on front right side of 
machine. The conveyor wheel will stop and start with conveyor shut-off rod. 

4.2.1.      Proper Chemical Dosage 

The amount of chemical delivered, whether it is detergent, sanitizer or rinse aid, is controlled using the set 
screw located on the circuit board attached to the control box.  

• 

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

Note:

  

Detergent pump only operates when hot water tank is filling or when prime switches are 

activated.

  

• 

Circuit board basic settings are: arrow facing 9:00 for sani and rinse, 12:00 for detergent. 

 

Adjustments To Detergent Pump:

 

• 

When replacement container is installed, push the prime switch in and hold until the detergent feed line is full. 

• 

Securely place overflow drain tube into soap tank and switch power on-off/flush switch to the “ON” position. 
The detergent dispenser will automatically dispense soap as the soap tank fills with water. 

• 

The quantity of product can be regulated at the circuit board using the set screw.  

Adjustments

 

To Sanitizer Pump:

 

• 

Follow same procedures as detergent for priming chemical. 

• 

Push conveyor rocker switch located on the front of the machine. Place sanitizer test strip under the final rinse 
and read for proper level.  

• 

The quantity of product can be controlled at the sani circuit board set screw. 

 

Note: Use chlorine test papers to verify and monitor the 50ppm chlorine level

Adjustments To Rinse Agent Pump: 

• 

Follow same procedures as detergent for priming chemical. 

• 

Cycle glasses through machine and verify glasses are sheeting properly. Increase rinse aid as 

necessary by turning up or down circuit set screw. 

• 

Basic circuit board setting is 9:00.  

Note: To meet standards set by NSF, chlorine at 50ppm must be used in the final rinse. 

 

4.3. Cleaning 

Instructions 

4.3.1. Highly Recommended Daily Cleaning Instructions

Note: conveyor motor can be pulled to the side as your placing wheel into position. Open 
front access door and pull conveyor motor toward you as seat the conveyor wheel into 
position. 

Place conveyor hub in center of conveyor, align shut-off rod to normal position. Install left and right 
trays, making sure shut-off rod is positioned between guide brackets. Install curtains into their 
holders. 

Upper and lower wash tank screens should be removed and cleaned thoroughly. 

Pull the drain tube from the soap tank and clean the tank.  

Insert overflow drain tube and wash tank screens back to appropriate placement.

 

Reattach optional GL-C waste collection assembly. 

Check product levels and close front service door.
