Installation Standards for KIWIVAC Built-In Central Vacuum Systems
The goal of installation is to first layout the most straight, direct route of tubing to assure the most efficient built-in central vacuum possible. Second, is to place the inlet valves in the most convenient, efficient, inconspicuous and easy-to-use locations that will not interfere with or compromise the integrity of the structure in which they are installed.

1. Tubing
   a. Only use the highest quality virgin PVC tubing made, no "regrinds" which cause rough interior finishes.
   b. All cuts are to be made with a thin-wall tubing cutter for straight, clean cuts, leaving no gaps between pipe and fitting seat.
   c. All pipes are to be deburred, assuring proper gluing and seating of pipe.
   d. Never use a hacksaw unless forced to!
2. Fittings
   a. Only use top quality fittings, which are produced in polished stainless steel moulds and are 25% heavier than inferior fittings.
   b. All fittings to have 19mm cuff, not 12.5mm.
   c. Only install tight 90 degree elbows at the inlet valve connection and will make offset jogs with two 45 degree ells not two 90 degree ells.
   d. Never install drop out tees (where the sweep part of a tee goes directly on top of another inlet valve run) because debris can fall down to the inlet.
3. Wire
   a. Only install 0.5 mm gauge wire or stronger for our low voltage wiring.
   b. Wire will be secured to the pipe every 1.5 metres minimum and at most elbows with plastic wire tie wraps or tape to insure a neat and safe installation.
4. Inlet Valves
   a. All inlets to be installed at exact height corresponding to electrical inlets unless otherwise specified.
   b. Never install fewer inlets than required to adequately reach all areas with a 9mtr hose, but in exceptional circumstances an 11mtr hose.
   c. Always attempt as accurate a colour match on inlet valves as possible.
5. Power Unit
   a. Never install any power unit, which is not adequately designed to handle the home into which it is installed.
   b. Always double check each finished installation to insure proper suction and airflow.
   c. Never install a power unit, which will emit dust or debris from the exhaust into the room into which it is installed.
   d. Never knowingly sell any consumer anything they do not need!
   
   The extra time required for our demanding standards is well worth the extra effort to us, the contractor, and to the end user. Demand these standards from whoever installs your vacuum system.
