WATER CHEMISTRY
Water quality is extremely important for the optimum performance of your ultraviolet light system.
Only install the ultraviolet light system when:
• Total Iron - count is less than 0.3 ppm (0.3 mg/l)
• Hydrogen Sulfi de - count is less than 0.05 ppm (0.05 mg/l)
• Suspended Solids - count is less than 10 ppm (10 mg/l)
• Manganese - count is less than 0.05 ppm (0.05 mg/l)
• Hardness - count is less than 7 gpg (where total hardness is less than 7 gpg, the ultraviolet light system
should operate effi cienctly provided the lamp/quartz sleeve is cleaned periodically. If total hardness is over 7
gpg, the water should be softened.
This sterilizer is specifi cally designed to supply water free of virtually all bacterias, viruses, algae and fungi by irradiating
the water with powerful ultraviolet light. The result is bacteriologixally safe water without the use of potentially harmful
chemicals...............Natures Way, with no residual disinfecting agent in your water.
INSTALLING YOUR ULTRAVIOLET LIGHT SYSTEM
• CAUTION: electronic ballast must be connected to a grounded receptacle and the lamp connector ground wire con-
nected to the stainless steel reactor chamber.
• The Ultraviolet Light System is designed to be mounted horizontally or vertically at the point-of-use or point-of-entry
depending on the specifi c fl ow rate of the unit. The ideal installation is vertical with the lamp connector on top.
• The ballast should be mounted either above or beside the reactor chamber. This will prevent moisture caused by con-
densation from entering the ballast enclosure, causing a potential for ballast failure.
• The complete water system, including any pressure or hot water tanks, must be sterilized before start up by fl ushing with
chlorine (household bleach) to destroy and residual contamination.
• For safety purposes, the Ultraviolet Light System should be connected to a ground fault interrupt circuit.
• The Ultraviolet Light System is intended for indoor use only, do not install Ultraviolet Light System where it may be
exposed to the weather.
• Install the Ultraviolet Light System on cold water line only.
• If treating the entire house, install the Ultraviolet Light System before any branch lines.
• A 5 micron sediment fi lter must precede the Ultraviolet Light System. Ideally, the Ultraviolet Light System should be the
last treatment the water receives before it reaches the faucet.
1) For shipping purposes, the UV lamp is packed in a separate cardboard tube. Carefully remove the UV lamp from the
shipping tube being careful not to touch the “glass” portion with your fi ngers. Insert the UV lamp into the quartz sleeve
and making sure the connection end is inserted last. Mount the Ultraviolet Light System to the wall with supplied clamp
(1 clamp on all 1 gpm units and 2 clamps on all 2, 5 and 8 gpm units). If required, a double-end clamp can be purchased
from your dealer to affi x to an RO membrane .
2) If the Ultraviolet Light System is to be hard plumbed, make sure you leave enough clearance in front of the lamp con-
nector to facilitate lamp service (a length equal to the length of the unit should suffi ce).
3) Various connection methods can be used to connect the water source to the Ultraviolet Light System, however union
type connectors are recommended. The use of a fl ow restrictor device is strongly recommended when installing your
Ultraviolet Light System in order that the manufacturers recommended fl ow rate not be exceeded. These fl ow restrictions
are available from your dealer. In addition, the use of a by-pass assembly is recommended for emergency use of untreated
water when you Ultraviolet Light System is being serviced. Note: When the UV unit is returned to service after being on by-
pass the complete water system must be sterilized once again with chlorine (household bleach) to destroy and contamina-
tion that may have entered the distribution system while on by-pass. Do Not Solder Connections While Attached
To The Ultraviolet Light System As It Could Damage The O-ring Seals.
4) Prior to connecting the power source, check all connections to ensure that they are indeed secure, turn on water supply
and check for any leaks. If satisfi ed that there are no leaks, proceed with the following steps.
5) To properly ground the stainless steel generating chamber, attach the green wire coming from the power source to the
grounding lug on the UV chamber. Remove the green cap nut and slide the eyelet connector onto the screw. Fasten the
cap nut to the screw with a 5/16” wrench.
6) The power source provided with your Ultraviolet Light Systemmust be located within (5) feet of an electrical outlet. Do
Not Use An Outlet That Can Be Switched Off (IE. A Waste Disposal Outlet). Attach the lamp connector to the UV lamp and
press into the aluminum gland nut. Plug the ballast into the outlet and ensure the “POWER-ON” LED is illuminated. The
audible will enter a self test mode when power is fi rst applied to verify ballast operation.
