Guidelines for Replacing Vacuum Lifter Tubes
 Top
Swivel/Control Head Preparation
Before installing the replacement tube, be sure the
vacuum control head and top swivel are clean and free from any previous residue.
Tube Installation
Before attempting lift tube
replacement, pre-stretch the tube lengthwise as much as possible. Smooth and
pull outward on the tube ends, removing any tendency to curl inward. Trim any
excess tube material on the ends of the tube using a razor knife. If the tube is
too tight over the vacuum control head or top swivel, the last two coils of the
tube may have to be removed by cutting the fabric with a razor knife and cutting
the wire with a pair of heavy duty cutting pliers. If the tube is too loose over
the vacuum control head or top swivel, wrap several layers of duct tape around
the area until the fit is snug. Clamping the top swivel and control head in a
bench vice or having an assistant help during tube installation is highly
recommended. Slide rubber sleeves (optional) and wire ring clamps (see diagram)
over the ends of the vacuum tube and temporarily tighten the lift tube clamps
over the top swivel. It is recommended that new clamps be used when replacing
the vacuum tube. Gradually pull tube all around until the top of the tube is
even with the top surface of the nylon ring. If the clamps cannot be slid over
the tube, place the wires of the clamp between the wires on the tube and turn
the clamps onto the tube. A screwdriver used as a lever and needle-nose pliers
help to ease the tube into position. Secure the top of the tube to the swivel
with (2) two clamps (VT250 sizes use one heavy duty clamp)
ensuring that the wire rings on the clamp sit evenly within the crests of the
tube without crossing over. The clamps should be placed in opposite directions
with the screw portions of the clamps positioned 180° apart. In a similar
manner, attach the other end of the vacuum tube to the control head. Secure in
place with (1) one wire ring clamp. Take special care to position the tube
evenly all around, ensuring that all holes in the control head are covered by
the tube. When replacing the vacuum tube on the VT-160 size only, be sure to
position the lower clamp below the raised band on the vacuum head to provide the
best possible attachment between control head and vacuum tube. Rubber sleeves
are provided to conceal the wire clamps if so desired. Their use is optional.
Warning: Use extreme caution
not to puncture the outer wall of the tube during preparation and installation
procedures. Doing so will weaken the tube and may cause vacuum leakage. If the
vacuum tube wall is accidentally punctured, cut away the damaged end and
reattach to the control head or top swivel. Check to ensure the tube is securely
fastened to the control head and top swivel by pulling or twisting the tube. A
very serious personal injury or unit failure may result if the tube is not
correctly installed. ANVER recommends replacement of both tubes, as a pair, on
the Double Tube systems.
