Tube Hangers
o
Tube hangers are an effective way to hang the piping
system from the beams running along the roof.
o
Consists of a Top Beam Clamp, a rod, and a hanger
properly sized to the piping.
Rubber Flex Line/ Pickup Hose
o
Rubber flex line is used on the
suction end of the central vac
system, and is used by the
operator.
o
The flex line has a static wire built into it to prevent static electricity build-up.
If servicing a rubber hose, ensure that the ground wire is making contact
with the coupling.
After the service, the installer must check the resistance by using an OHM
meter on the couplings while they are in contact with each other.
The conductivity of the
coupling should read between
0 and 5 ohms resistance.
o
Also available as a clear hose.
