6.Use 2 people to move the machine in order to install the legs.

7.Have 1 person behind the glasswasher tilt it back as the person in front twists the machine to the right. This makes the front left leg mounting hole accessible.

8.Screw 1 of the legs tightly into place. Repeat this process for the remaining legs.

9.Lift the glasswasher off the pallet, and re-install the front door..

10.Level the glasswasher front-to-back and side-to-side by adjusting the leg bullet feet in or out.

11.Compare the site utilities with the data plate specifications. If they

agree, then proceed with the installation according to the diagrams on the next page.

12.Remove the packing material in the glasswasher and discard, then remove any protective film on the machine.

Tilt the machine back to clear plumbing connections.

Twist the

Chemicals

Glassware cleaning chemicals

1.A qualified chemical supplier should supply liquid detergent, sanitizer and rinse-aid for the glasswasher. The glasswasher manufacturer does not sell glassware washing chemicals.

2.A chemical's formulation and strength vary depending on the chemical supplier; therefore, the specifications given below are approximations only.

3.The glasswasher has 3 built-in chemical dispensing pumps for

Detergent - Use a commercial grade non-chlorinated detergent specifically made for glasswashers.

The recommended concentration of detergent should be .35%

Sanitizer - 2 types of sanitizer may be used.

(5.25%) Sodium hypochlorite (chlorine bleach) to provide a minimum concentration of

50 ppm in the final rinse. The 50 ppm concentration must be checked using test strips to make sure the proper concentration is maintained.

Iodophor (Iodine formulated with a rinse agent), to provide a minimum concentration of

12.5ppm in the final rinse. The 12.5 ppm concentration must be checked using test strips to make sure the proper concentration is maintained.

Rinse-aid

Consult your chemical supplier for the proper type of rinse-aid to use in the glasswasher.

Installing chemical supply containers and chemical pick-up tubes

1.There is enough space inside the lower compartment to hold

3 one gallon containers for detergent, sanitizer, and rinse-aid.

The contents of each container must be marked clearly.

2.The glasswasher comes equipped with 3 gray tubes, called stiffener tubes, and tubing for each chemical pump.

The tubing inserted in the chemical container has a strainer.

3.The outlet tubes from the supply containers to the chemical pumps are marked with color-coded labels, they are:

RED -	Detergent	(DET)
CLEAR -	Sanitizer	(SAN)
BLUE -	Rinse-aid	(R/A)

4.Pull the stiffener tubes and chemical tubing forward and out of the compartment. Make sure the tubing is not tangled or kinked.

5.Insert the stiffener tube and pick-up tubing into its container and stow the supply containers in the lower compartment as shown to the right.

Priming the Chemical Injectors and Approximate Chemical Settings

Each chemical injector can be adjusted using its prime button and concentration adjusting screw. These controls are located on the right side of the control box located in the lower compartment of the glasswasher. The white injector rotors are visible through the control box window.

	Chemical Injector Prime and Concentration Controls

ALL OF THE CHEMICAL SETTINGS BELOW ARE APPROXIMATIONS.

CONSULT A QUALIFIED CHEMICAL REPRESENTATIVE TRAINED IN THE USE OF THE TEST EQUIPMENT REQUIRED FOR TAKING SAMPLES AND PERFORMING ADJUSTMENTS.

1.Priming the Pumps:

Make sure the proper chemical pick-up tube is in its supply container, then

push and hold the prime button until the detergent, sanitizer and rinse-aid feed tubes are full of chemical. Release the Prime button.

2.Approximate Chemical Settings:

The approximate chemical volume dispensed by the chemical injectors can be determined by counting the number of revolutions of the injector rotor.

Detergent - 1 revolution in 1-second of the detergent pump rotor 0.35% concentration.

Sanitizer - 1 revolution in 5-seconds 12.5 ppm of Iodophor or 50 ppm of chlorine.

Rinse-aid - 1 revolution in 8-seconds the median volume recommended.

Turn the Injector Concentration screws clockwise to increase or counter-clockwise to decrease the volume of dispensed chemical.

3.The detergent chemical setting must be performed when the hot-water fill solenoid valve is open. The hot-water valve is open when the power switch is in the ON position during initial fill and when the detergent tank float assembly calls for hot water

The sanitizer and the rinse-aid setting can be performed whenever the cold-water fill solenoid valve is open. The cold-water fill valve is open whenever the glasswasher power switch is ON and

the conveyor is turning. A separate rinse-aid is not needed when Iodophor is used as a sanitizer. Turn the Injector Concentration Screw fully counter-clockwise until the rinse-aid injector rotor stops turning.

Quick Operation Guide
The glass washing machine is designed
to automatically wash a wide variety of glassware.			8
The glass washer consists of a wash section and
rinse section. Glasses rotate on a conveyor
through each section. A wash tank in the lower
compartment holds heated wash water. The water
level in the wash tank is maintained by a float and
cam-operated switch. The wash tank water
temperature is controlled by a heater and a		1
thermostat. The rinse water is supplied from
the cold water supply. Chemicals are auto-
matically dispensed by built-in chemical pumps			2	3
