Regulating Flow to the UV:
If the water flow through the UV clarifier exceeds the
recommendations, you may put a ball valve in the tubing to restrict
and regulate the flow. Place the ball valve between the pump and the
UV clarifier unit.
Positioning and Assembly
The Tetra®Pond GreenFree® UV Clarifier is not submersible and should
be positioned outside the pond where there is little likelihood of it
sitting in puddles or falling into the pond.
It is recommended (but not necessary) that the UV clarifier is attached
to the tubing that enters external pond filter. This prevents the flow
restriction caused by the UV restricting the flow of the filter.

UV Bulb and Quartz Glass Tube Installation
Insert the UV-C bulb into the connector. (Note: Avoid touching the
bulb with bare hands and remove any marks using a clean cloth or
tissue. Oil from your fingers can reduce the life of your bulb.)
The quartz glass tube is positioned with three rubber O-rings in place.
Be sure O-rings are positioned properly to form a tight seal. Water
entering inside the quartz tube may cause damage to the electrical
components.
Connecting the UV Clarifier to the Pump
The inlet connection (marked in ) is the one closest to the screw cap
of the UV unit. Connect the pump tubing to this inlet.
All UVs come with 2 three-stepped adapters that fit the following
internal diameter tubing (ID):
¾ in., 1 in. and 1 ¼ in. ID
• Choose the hose adaptor size of the UV
according to the tubing used.
• Make sure that the hose adaptor for the outlet
(marked out ) is at least as large as the inlet.
- Cut the hose adaptor in the groove with hacksaw to fit the tubing
selected (if necessary).
Ensure that the gasket is in place before attaching the hose adaptor
into the unit.
• Hand-tighten the hose coupling rings. Do not use a wrench.
• Secure hoses to adaptors with hose clamps (not included).
UV Clarifier – Electrical Connection
Please read safety instructions before plugging the unit into the
electrical outlet.
• When working, a purple UV light can be seen through the viewing
window located in the UV housing.
• An operational test can only be carried out when the equipment is
fully assembled.
Seasonal Use
Summer: The unit should remain in operation 24 hours a day.
Winter: It is recommended to store the unit in a frost-free location.
THE WARRANTY DOES NOT COVER DAMAGE TO THE UV CLARIFIER
DUE TO FREEZING TEMPERATURES.
Maintenance and Care
When carrying out any maintenance, the unit must be disconnected
from the electrical circuit.
• Clean the unit at least twice a year. A clean quartz tube will allow
the UV light to be more effective in controlling algae. More frequent
cleaning may be required for ponds with severe algae growth.
Tip: Use warm vinegar to wipe the quartz sleeve for a faster clean and
efficient removal of mineral build up.
