INSTALLATION

UNPACKING

Remove the carton from around the machine. Remove the four bolts holding the machine to the skid. Unpack the chopper cylinder assembly.

Immediately after unpacking the chopper, check for possible shipping damage. If this machine is found to be damaged after unpacking, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, test the electrical service to make sure that it agrees with the speciﬁ cations on the machine data plate.

The four leg assemblies (Fig. 1) are removed and packed in a separate carton for shipment. Unpack and assemble these legs by screwing them into the four tapped holes of the frame. The rubber feet on these legs cushion the machine. Under normal operation, the machine need not be bolted down.

ELECTRICAL CONNECTIONS

The electrical cord on this machine is equipped with a grounding- type plug which must be connected to a properly grounded receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove the grounding prong from the plug.

Choppers with three phase motors should be connected so that the hub drive runs counterclockwise facing the cylinder assembly.

A check must be made to verify correct direction of rotation. Energize machine momentarily by turning switch ON then OFF.

If rotation is incorrect, disconnect plug from electrical outlet, disassemble the plug and interchange any two power leads (not the green ground lead). Then reassemble the plug and recheck.

CLEANING

Unplug chopper power cord before cleaning.

The chopper must be thoroughly cleaned and sanitized after installation and before being placed into service.

Cleaning Supplies (Not Provided)

Recommended cleaning and sanitizing supplies include:

• A 12" handle nylon brush that will slide through the cylinder

• A two compartment pail for cleaning solutions

• A pail for sanitizing solution

• A scrap pail

• Clean cloths

• A spray bottle

NOTE: When using detergents and sanitizers, follow manufacturer's instructions. Rinse with clean water.

Prepare a hot detergent solution in one side of the two compartment pail. Fill the other compartment with warm potable rinse water.

Mix a sanitizing solution by adding one tablespoon of sodium hypochlorite bleach (5.25%) to one gallon of water in a pail. This makes a 200 ppm solution. Use this solution to ﬁ ll the spray bottle as well as the pail for sanitizing.

Thoroughly clean and sanitize the feed pan, feed stomper, chopper cylinder assembly, worm assembly, knife, plate, adjusting ring and machine housing. Refer to Fig. 1 for component identiﬁ cation.

NOTE: After cleaning, apply a light coat of food grade mineral oil to the cylinder, adjusting ring, knife, plate and worm before reassembly.
