4.5 UV STERILIZER INSTALLATION
The SP Series UV unit is shipped with the UV lamp,
quartz sleeve, fittings, and O-rings and need to be
assembled before the UV unit can be used.
1. Install the UV unit in a sheltered,
well ventilated area.
2. Install the UV unit as close as possible to the
point-of-use to avoid potential contamination
discharge from pipes, fittings, etc.
3. The UV unit should be mounted on stable
support to avoid straining or warping.
Allow sufficient clearance around the unit
for servicing.
4. Verify the location is free from vibration.
5. All UV units are rated for maximum operating
pressure at 50 psig (8.24 bar).
6. The UV unit must be properly grounded for
safe and proper operation. Failure to properly
ground the UV unit automatically voids all
unit warranty.
7. Line voltage must be within 10.56V to 16.50V.
Voltage outside the range will compromise the
performance of the UV unit.
Plumbing Requirements
All piping, tubes and hoses leading to the UV unit
connection points must be leak-free before the UV
unit can be installed.
NOTE ! The UV unit may be installed
horizontally or vertically. For vertical
installation, make sure the inlet port is
positioned at the bottom.
Installation Procedure
NOTE ! Do not assemble or install
damaged parts. Quartz sleeve and UV
lamp are fragile and must be handled
with care.
Install Fittings
Perform this procedure to prepare the UV unit for
installation.
1. Inspect each port and fitting to ensure threads
are free of dirt, burrs, and excessive nicks. If
threads are badly nicked, replace the fitting.
2. Wrap ¼ inch (6.35 mm) wide PTFE tape 2 to
3 turns counter-clockwise around the male
threads of the ¼ inch (6.35 mm) fitting.
DO NOT wrap tape around the first thread.
