Installation
GENERAL CONSIDERATIONS FOR ALL
DISINFECTION UNITS:
1. When installing the equipment, it is necessary that the
unit be isolated from vibration, heavy equipment, and
poorly connected piping.
2. Incoming wate
r temperature to the unit should not
exceed 35° minimum to 110° maximum degrees Fahrenheit.
3. The operating pressure should not exceed 100 psi.
4. Before putting the unit into final operation follow
sanitation procedures as outlined in this manual for proper
disinfection. Sanitizing all discharge piping and fittings
with household bleach from disinfection unit to point of
use removes existing contaminants and gives the unit a
“clean start.” Be sure to rinse with U.V. treated water.
5. A proper flow control, included with the unit, must be
use to insure only the designated flow through the unit.
6. It is recommended to use UV resistant materials when
initially installing unit. The UV light can cause PVC or
other plastic materials to degrade. Becoming brittle, this
can compromise the pipe or fitting structural integrity.
GENERAL PRECAUTIONS TO BE FOLLOWED
AT ALL TIMES:
1. Al
ways disconnect electrical power to any U.V. unit
before servicing.
2. Under
no circumstances should personnel look at a U.V.
lamp in operation (EXCEPT through an external sight Port
lens located on the outside of the unit).
3. U.V. disinfection units must always be properly grounded.
The DWS series are always placed after the pressure
tank and any other type of treatment devices (i.e.
softeners, filters).
These units are normally installed in a verti
cal position in
an
enclosed
area with good ventilation. Allow clearance of
at least the unit’s length at one end for quartz sleeve and
lamp replacement. Four (4) anchor bolt holes are provided
for proper wall support. Use anchors with screws for
sufficient support (not included). A lock nut secures the
mounting bracket to the U.V. chamber.
If your piping system is subject to impulse pressure resulting
in a “w
ater hammer” condition, a surge tank or other means
must be provided to remove this condition; otherwise, this
extreme shock pressure condition may rupture or fracture
the quartz sleeve.
Make all plumbing connections to allow for ease of service.
Be sure to follow all local plumbing codes and U.V.
restriction requirements where specied by local authorities.
STEP BY STEP INSTALLATION:
1. Turn off the water before cutting into the water line.
2. Assess the installation (i.e. type of pipe, size of lines,
etc.) and obtain necessary plumbing ttings for installation.
Inlets and outlets on 8 gpm units are 3/4” MNPT. Use
Teon tape on all threaded connections and avoid iver
tightening.
NOTE:
The ow control is a press in type. Each unit has
a 3/4” MNPT inlet/outlet machined so the press in
ow control can be easily inserted into whichever
port you select for the inlet. Make sure the rubber
part of the ow control is facing outward from the
port selected. Simply hand press or slightly tap in
the ow control until it sits on the inside ledge of the
machined port.
3. Using the mounting bracket provided, secure unit to
wall, or other surface. Make sure to allow enough room
to install, replace, and clean the quartz sleeve and lamp.
Installing a water shut-off valve before and after the unit is
recommended to make servicing easy.
4. After mounting, install quartz sleeve, O-Ring, and lamp
per instructions. Turn on the water slowly, check for leaks,
and repair as needed prior to full service operation.
5. After the unit is full of water, plug it into a grounded
110V outlet. Observe operation through the Site Port.
The lamp will show a bright blue glow. If any problems
are noted, consult trouble shooting guide.
