Tubing and Fittings Installation Guide.

This guide offers general recommends of how to properly install a central vacuum housekeeping system.

These systems are different from water, steam or dust collection duct system.

Follow these few basic principals and your system should provide trouble free operation.

 Compression Couplings  Instalok Coupling  Top in Drop (Preferred drop method)  Side in Drops  Labels  Zoned System Design  Elbows  Eliminate Inclines (Horizontal or Vertical Only)  Tubing Supports

IMPORTANT INSTALLATION INSTRUCTIONS PREPARING FOR INSTALLATION

Figure 2

■ Verify tube and Instalok sizes correspond with each other ( Figure 1 ) ■ Clean and dry tube OD to ensure it is free of dirt and grease which can cause slippage ■ Make sure tube ends are cut square and burr-free to avoid material blockages

ASSEMBLING TUBE & COUPLING

■ Twist Instalok onto tube end ( Figure 2) until tube is centered in coupling ( Figure 3 ) *NOTE: Twist Instalok or tubing to facilitate installation ■ Tighten clamp ■ Twist the connecting tube into the Instalok until both ends butt together ( Figure 3 ) ■ Tighten remaining clamp

TIGHTENING THE COUPLING

■ Tighten the bolts to 50 foot-pounds of torque MAXIMUM ( Figure 4) ■ Do not over-tighten

ELBOWS

Provide 10 times the tube diameter of straight tube before and after each elbow.

Example. For 3" Tubing, provide 30" before and after each elbow minimum.

Avoid back to back elbows whenever possible.

Avoid tight bend elbows (No Street El) Centerline bend radius should be a minimum of 2X the diameter.

3X diameter or larger prefered.

Tube Trap to eliminate oversize debris.

The tube trap is an alternative to the standard inlet valve adapter. It provides a system to catch large debris that should not be vacuumed into the central system. Rags, gloves, pieces of skids, shop towels, bolts, and other debris can jam a rotary airlock or get logged into the tubing system. The tube trap captures these items at the inlet valve so the operator can clear these themselves before they enter the system.

When used with the sight glass assembly, the operator can see objects trapped visually to identify whether they need to be cleared quickly.   

Tube Trap adapters are 304 stainless steel.

Heavy duty construction.

Works with standard inlet valves and can be retrofitted to existing systems with straight drops.

See a video of this product on our YouTube channel.

Tube Trap only works with a straight inlet adapter.
