Unpacking

1.Inspect the shipping container carefully for damage. Contact the carrier promptly if there is damage.

2.Open the box and inspect the contents carefully. There should not be any loose or damaged parts in the container.

3.Compare the packing slip against all the items in the box. Report any shortage or other inspection problems immediately.

4.Remove the PR70 system components from the container. Do not lift the machine by the tanks.

Locate and Install the PR70

1.Locate a bench top or equivalent location to mechanically mount the PR70 dispensing machine.

Verify the location has access to compressed air, AC power and is well ventilated.

2.Place the PR70 onto the designated location. Allow to the machine to rest on the rubber feet provided.

3.Turn the Shield Locking Screws clockwise on both sides to remove the PR70 protective shield.

4.Attach the PR70 frame to the selected location by installing fasteners (not provided with unit) thru the 4 mounting holes. Refer to Figure 1 for mounting hole dimensions.

2.Load material into the on-board or off-board tanks feeding the machine.

3.Using the power cord provided, connect AC power (100-240V, 50/60 Hz, single-phase) to the machine.
