Machine-Mount Installation

In this installation, the RPV is mounted directly to the material inlet of the hopper loader or vacuum hopper it will serve. The hopper loader or vacuum hopper inlet tube provides the support for the RPV.

WARNING! Make sure that the hopper loader or vacuum hopper inlet can support the weight of the RPV (approximately 10 lbs.) and any unsupported material supply hose. A properly-installed hopper loader or vacuum hopper can support 250 lbs. of downward force. If you are installing your RPV on equipment from another manufacturer, consult them for advice on support capabilities.

1.Check the RPV single outlet tube diameter and the hopper loader inlet size to be sure you have the necessary coupler and transition tube (if needed) to connect the RPV to the hopper inlet.

2.Chamfer and smooth the hopper loader or vacuum hopper inlet tube to prevent damage to the O-rings inside the tube coupler.

3.Apply silicone lubricant or equivalent to the inside of the tube coupler to ease insertion.

4.Insert the single material outlet tube into the tube coupler past the O-ring. Be careful to avoid damaging the O-ring.

5.Slide the RPV onto the hopper loader or vacuum hopper with a side-to-side motion. Be sure the tube passes the O-ring for an air-tight seal. Avoid damaging the O-ring.

6.Tighten the set screws in the tube coupler to lock the RPV in place.

7.Attach the material pick-up wands to the RPV inlet tubes using flex hose and hose clamps. Route the material conveying hoses so they don't interfere with workspace or create a tripping hazard.
