where to install the unit
The UV unit should be installed after all other water
conditioning equipment. Mount the unit to a wall or
braced frame using the mounting tabs. Install a bypass
with unions.
Install the UV treatment unit in a sheltered area with
ample ventilation. Ambient temperatures surrounding
the unit should be between 35
o
F (2
o
C) and 110
o
F (43
o
C).
Should your requirements differ, contact the factory for
assistance.
As an ultraviolet UV treatment unit does not introduce
any chemical residue within the water, it is desirable to
install the unit as close as possible to the point of use in
order to avoid potential recontamination by discharge
pipes, fittings, etc. The base of the UV treatment unit
should be mounted on suitable support to avoid undue
strain on the unit or your related pipes and fittings.
The UV unit should be installed after all other water
conditioning equipment and as close to the end point of
use as possible. For example, it should not be installed
in a remote well house; it should be installed at the
house. If filtration or other water treatment equipment is
installed, the UV unit must be installed after all such
equipment.
how to protect your unit
The location should be free from undue vibration which
could be caused by proximity to heavy equipment and
erratic or improper pumps. Excessive vibration will
damage internal electrical components and cause
premature failure of the UV lamps.
If your piping system is subject to impulse pressure
resulting in a “water hammer” condition, a surge tank or
other means must be provided to remove this condition,
otherwise the extreme momentary pressure may rupture
and fracture the quartz sleeves.
operating pressure
Standard units are rated for a maximum operating
pressure of 120 psig (8.3 bar).
A parts check list was included when
this unit was shipped. Please refer to
this list and note that some parts are
small and can be easily overlooked
when discarding packaging.
DW-8 installation
Allow 40” (102cm) service access clearance on the inlet
side and 12” (31cm) on the outlet side clearance on the
opposite end of the unit. For the DW-8 DE unit, a
minimum of 2 feet clearance is required below the
bottom of the unit to operate the drain valve (supplied
by others).
If vertical installation is required due to lack of horizon-
tal access space, the inlet water connection
must be at the bottom.
DW-5 installation
Allow 16” (41 cm) service access clearance on both
ends of the unit.
If vertical installation is required due to lack of horizon-
tal access space, the inlet water connection
must be at the bottom.
grounding
It is imperative that the unit be properly grounded for
safe and proper operation.
Failure to properly ground the UV unit automatically
voids the equipment warranty.
Line voltage to the UV unit must be stable. Performance
will be reduced should incoming line voltage drop more
than 5% from the rated voltage as indicated on the
nameplate decal on the unit.
