Use the following method to check the location of vacuum inlets:
•
Simulate cleaning each room using the hose. To do this, ask an assistant to hold the end of the hose at the
point where you have assessed the inlet location. Walk around with it to cover the entire area, including the
corners at the ceiling. If you do not yet have the hose, cut a piece of string the same length as the hose.
IMPORTANT!
Don't forget to simulate cleaning the stairs and every room!
3. GENERAL INSTALLATION INFORMATION
MEASURING, CUTTING AND ASSEMBLING
For all measurements, include an overlap of 3/4 in. (19 mm) for piping and fittings. Start assembly from the
furthest vacuum inlet and work towards the Power Unit. It is important to measure and trial fit each branch before
applying adhesive! When you are sure that the dry assembly is correct, apply adhesive to this branch and move on
to the next.
1.
Always cut piping at 90° with:
•
A Nuera pipe cutter
•
Electric radial saw
•
Miter box & hack saw
IMPORTANT!
Only use a saw with a blade that is compatible with plastic.
2.
Always de-burr all cuts - medium grit sandpaper or a utility knife works well. This will facilitate connecting and
give optimal air flow.
DANGER
Take care not to cut yourself!
3.
Always apply solvent around the end of the pipe and never inside the fitting.
IMPORTANT!
If you apply solvent inside the fitting, the adhesive will be pushed up in a mass
inside when the pipe is introduced. Debris may accumulate on the obstructions an
eventually block the pipe.

If structurally possible, install a vacuum inlet close to the door to increase the reach of the hose outside during the
summer.
PIPING
Before starting installation, plan the trajectory of the piping system to be the most effective. To do this:
•
make sure that the ducts are as direct as possible
•
avoid installing unnecessary fittings
•
avoid using short right angle (90 deg) fittings - use 45 degree fittings to make changes in direction. If this is
impossible, use long right angle fittings.
•
only use short 90 degree fittings for inlet installation
First, locate the piping connecting the Power Unit to the furthest vacuum inlet. This is the main line. Then connect
other inlets to this main line using long-T or 45-Y fittings, or with a series of 45 degree fittings.
4.
Make connections in the direction of airflow.
CORRECT
INCORRECT
5.
Always install a short 90° universal elbow on the inlet mounting plate to prevent entry of large objects and to
be able to install in a partition wall. To install a vacuum inlet in the middle of a long pipe, use a short tee.
If a vacuum inlet passes directly through a wall, install the short universal elbow behind the wall. Though
blocking is unlikely, an accidentally vacuumed object can be easily removed.
ADHESIVE
The adhesive used for vacuum piping is specifically designed for bonding PVC piping for a central vacuum system.
Do not use plumbing piping adhesive.
Use of the adhesive
1.
Degrease all joints;
Apply a thin coating of solvent on the ends of the pipes with the applicator. Do not apply to the fitting interiors;
2.
3.
Insert the pipe into the fitting, turning while inserting to spread the adhesive evenly. Adjust the final position
quickly - curing time is several seconds. If the position is incorrect, withdraw the pipe immediately, reapply
adhesive and try again;
4.
Wipe off adhesive with a rag and let stand for 2 minutes making sure that the connection stays in place.
5.
Allow to dry for 3 hours before use.
