Install the UV after the unit is in its final mounted location.
Use Teflon tape on all threaded connections and do not over tighten.
Connect 2" I.D. hose using a female 1.5" coupling, a 1.5" male NPT to a 2" barbed tubing fitting and a stainless steel hose clamp (not supplied) . For easy removal of the hoses at a later date, it is recommended using 1.5" NPT female quick connect unions on all 3 ports.
Connect the hose from the pond pump to the valve port marked "PUMP". It is recommended to use an inline check valve on this connection.
Connect the hose from the valve port marked "RETURN" to the waterfall or directly to the pond.
Connect the safety ball valve (included) to the port marked "WASTE". Connect the hose from the safety ball valve to an area where waste water can be discharged and not flow back into the pond, such as your garden or a dry well. This water is an excellent source of nutrients for your plants.
Leak Test/Function Test:
The waste port safety valve should be in closed position. Turn the main valve selector to the "FILTER" position. Turn on the pump and check the hoses and clamps for leaks.
Plug in the UV light if it is assembled within the filter unit. Look for visible light through the clear valve and agitator handle. The light coming through the clear plastic and handle is safe to look at. **Never look directly at lamp rays**
Filter Operation:
Normal filter operation should be at 0-3 PSI on the gauge. If it reads more than 3 PSI, the filter needs to be backwashed. It should be backwashed once a week regardless of the gauge pressure.
**Waste port valve must be open anytime you open or close the main valve**
Backwash:
Open the safety ball valve that is mounted in the "waste" line. Rotate the main valve knob to the "Backwash" position. The pump may be running during this operation.
Turn the agitator handle left to right and repeat approximately 10-20 times until the water comes out of the waste line nearly clear.
If the agitator handle becomes difficult to move, turn the main valve to the "rinse" position to clear the accumulated debris from the agitator mechanism. Then, return to the "backwash" position and continue moving the handle to clear out the remaining debris.
Rinse
The rinse operation works the same as the backwash except the water goes through the filter in the opposite direction to help remove any clogs inside the filter.
Rotate the main valve knob to the "rinse" position. Open the shutoff valve at the "waste" line. Turn agitator handle left to right approximately 10 times. When the water comes out nearly clear, rotate the main valve knob to the filter position, then close the shutoff valve on the waste line to resume filtering. The gauge should read 0-2 PSI normal filter pressure.
Filter Cleanout
At the end of the season the filter can be cleaned and winterized. If you backwash regularly, or have a bottom drain and/or non-freezing conditions you may never need to do this.
Pull out the plug and remove the UV ballast by unscrewing it. Pull the unit straight out being careful not to break the UV lamp. Remove the quartz sleeve. To remove the sleeve for cleaning, take a kitchen knife or thin screw driver and pry between the rubber flange and tube adapter.
Remove the 3 hoses from their respective ports. (**If a flexible hose is used, you may not need to remove them from their ports**.)
Remove the clamp ring by unscrewing the T-handle. Pull from side to side, pop off the main cover and then carefully pull straight up so not to break the UV quartz sleeve (unless it has already been removed).
Open bottom drain (if installed). If there is no bottom drain, pump the water out of the drum. Use a Wet/Dry shop Vac with a strainer on the nozzle or submersible pump to remove the water from the drum. DO NOT REMOVE THE MEDIA. DO NOT
