Ingersoll-Rand NP322L01-1 specifications General Description, Installation, Operating Instructions

GENERAL DESCRIPTION

ARO systems are totally enclosed, sealing the material in the system from air and moisture, preventing premature cure-out of the material. This allows for either continuous or intermittent use of the system and reduces the need for daily system clean-up.

The built-in lift capability allows for quick drum changeover and easy lift- ing of pump assembly from the container.

INSTALLATION

The NP322L( )( )-( ) Chop-Check Dispensing System comes completely assembled. Remove unit from crate and place on a level surface. Install material hose and dispensing device as required.

When the following instructions are observed, heavy paste materials can be pumped directly from their original 5 gallon drum without air inclu- sion, or excessive waste. The follower plate creates an air tight seal as well as clean-wiping action in its progressive downward movement into the drum.

OPERATING INSTRUCTIONS

TO RAISE LIFT:

1.Adjust (turn needle valve knob counter-clockwise) air pressure to lift. Connect the air supply (160 PSI MAX) to the air inlet.

2.Raise the lift high enough to clear the height of the drum. Stop the lift’s upward travel by adjusting (turn needle valve clockwise until tight) needle valve.

3.Check vent plug on follower plate to be sure it easily threads in and out. It is recommended to lubricate the threads of the plug to help prevent possible set up of compound at this point. See 65184X-X Follower Plate Operator’s Manual.

TO LOWER LIFT:

WARNING PINCH HAZARD. Follower can descend quickly causing injury. Keep hands clear when aligning with container.

NOTE: Be certain the Follower Plate vent plug has been removed so that the air trapped between the follower and the material is allowed to escape from this vent. Captured air between the follower plate and drum will escape.

NOTE: The lift may hesitate momentarily before starting downward. The air pressure inside the post air chamber must decrease before it will be- gin to descend.

1.Disconnect air line from the lift air inlet. Adjust (turn needle valve knob counter-clockwise) needle valve to lower the pump end into drum.

2.Replace the vent plug once the material begins to ooze from the vent opening.

3.Adjust (turn pump air regulator knob counter-clockwise to prevent over pressurization of pump) knob on pump air regulator.

4.Connect air line to pump air regulator and adjust (turn pump air regu- lator clockwise) air until pump begins to cycle.

5.Trigger gun to prime pump with material.

TO RAISE LIFT, (NORMAL OPERATION):

1.Disconnect air line from pump air regulator and connect to lift air in- let. Adjust the follower plate air valve pressure up to approximately 8 psig (.55 bar). DO NO OVERPRESSURIZE THE DRUM to avoid damage.

NOTE: Air from this valve will only pass when the unit is being raised.

2.Adjust (turn needle valve knob counter-clockwise) air pressure on lift.

3.Raise the lift high enough to clear the height of the drum. Stop the lift’s upward travel by adjusting needle valve knob counter-clock- wise.

REFER TO PAGE 3:

1.Once lift assembly and pump are in the “UP” position, place and cen- ter an opened 5 gallon drum of material on the lift base. Use the stops on the base to center the 5 gallon drum. Tighten thumb screw to secure drum.

2.Lubricate lower follower wiper plate seal with grease. NOTE: Make certain the grease is compatible with the material being dispensed. This ensures a smooth fit into the pail as well as prevents curing type compounds from bonding to seal.

TO CHANGE DRUM:

NOTE: The needle valve knob should be turned clockwise to hold lift in the “UP” Position.

1.Unscrew thumb screw and remove old 5 gallon drum.

2.Place and center a new drum into position. Remove cover. Tighten thumb screw.
