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 water temperature to the unit should not exceed 35° minimum to110° 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 must be used to insure only the designated flow through the unit.
GENERAL PRECAUTIONS TO BE FOLLOWED AT ALL TIMES:
1.
Always 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 Site Port lens located on the outside of the unit).
3.
U.V. disinfection units must always be properly grounded.
INSTALLATION:
The DWS/SE/DWSW 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 vertical position in an enclosed area with good ventilation. Allow
clearance of at least the unit’s length at one end for quartz sleeve and bulb replacement. Four (4) anchor
bolt holes are provided for proper wall support. Use wall plugs with screws for sufficient support
(not included).
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, 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 specified by local authorities.
On models requiring a U.V. monitor or light detector, the U.V. should be mounted in a vertical position.
