Jebao PU-36 User Manual

Mode# PU-36 Max GPH: 4400GPH Length: 19.5-inch
Positioning and Assembly
The Jebao PU Ultraviolet 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 the
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 UVC 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 two 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 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):
3/4", 1", 1-1/4" and 1-1/2”.
Choose the hose adaptor size of the UV according to the tubing used.
Make sure that the hose adaptor for the outlet 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).
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.
