Where microbiological activity is indicated to be present in your water
source, it is highly recommended that additional disinfection barriers be
used in addition to your UV system. This could include water well
chlorination using a pellet dispenser, inline chlorine injection using a dosing
pump and a contact tank, <1-micron absolute filtration or ozone injection.
The use of multiple barriers will assure safe drinking water in the event of
the failure of any one of the disinfection methods.
INSTALLATION CAUTIONS
Connect your UV lamp to a grounded (3-pronged)
receptacle (120V/60Hz) (
a GFI and power surge
protector is highly recommended
) and ensure that
the lamp connector ground wire is connected to the
grounding stud on the end of the reactor vessel.
Grounding Lug
1. Excelight UV disinfection devices are designed to be installed on the cold-water
line only.
2. Install the Excelight UV disinfection system indoors in a protected area where
the temperature does not fall below 4°C (40°F) and the humidity level is low (to
prevent condensation on the chamber). This unit functions optimally between
9-29°C (49-85°F)
3. Use Teflon tape on all plumbing connections.
Do not use other sealants.
4. If a pump is used in the water filtration system where the UV disinfection system
is installed, the UV disinfection system should not connect to the same AC
supply circuit as the pump. The voltage drop caused by the pump starting may
trigger an abnormal operating condition alarm on the UV ballast.
INSTALLATION PROCEDURE
In most installations, your UV disinfection system should be the last component in
your water treatment system, downstream from all other equipment. Choose a
location for installation with easy access to a 120VAC electrical outlet. This UV
system must be installed vertically with the inlet port positioned below the outlet
port.
A minimum distance of 17” (438mm) clearance is necessary to remove the
UV lamp from the reactor. If this is not practical the reactor can be removed
from the mounting clips for maintenance. Use of unions on the inlet and
outlet will facilitate this removal.
