Connecting Nozzles
All the supplied nozzles have two inlet ports with push in, quick release style fittings as shown in
Figure 6: Quick Release Fittings. These fittings are only designed for use with 1/4” O.D. plastic
tubing. If other than Nortec supplied tubing is to be used, it must be a high grade uniform
tubing from a reputable supplier.
The Nortec supplied fitting uses an o-ring to seal the O.D. of the tubing and finger clamps to
hold it in place. Failure to use proper size tubing may result in poor sealing and cause system
failure. The tubing MUST be cut square using a knife or plastic tube cutter rather than pliers.
To connect the tube to the nozzle simply push the tubing into the nozzle fitting until it reaches
the bottom. Gentle pulling of the tube without movement is a good indication that a proper seal
has been made.
Allow enough free tubing to permit the nozzle to swivel horizontally or vertically for future
pointing alignment.
Saddle Clamp Installation
The type of clamp used by Nortec, as shown in Figure 7: Saddle Clamp, requires that the pipe
be drilled first. Drill a 1/4” hole squarely into the air and water pipes close to each nozzle
within 24” (60 cm). Place the sealing gasket on the male part of clamp, insert it into the drilled
hole, then clamp it into place using the provided screws. The saddle clamp has a 1/8” FNPT
port; install either the supplied compression fitting or another style fitting suitable for plastic
tubing. Two saddle clamps, one for air and one for water, are required for each nozzle.
Note: Not to be used with DI water. For DI water use stainless steel tee.
