WINTERIZING YOUR FILTER
It is best for all biological lters to operate 24/7.
If you live in an area where you experience hard freezing, you may decide to shut your lter down for the winter. Do the
following:
1. Do a good backwash of the lter. Move the multiport valve to the "winter" position (between CLOSED and WASTE).
2. Turn o your pump and open the drain plugs on the pump strainer basket.
3. Open the drain plug at the base of the main lter and then the air release valve at the top of the lter. Water will drain out of the lter, but
no beads will be lost (Xclear Bead lter 400/500/600). CAUTION! The Xclear Bead lter 750/900 do not have a valve outlet with strainer
which causes the beads to come out of the lter. Keep close attention when the beads start coming out of the lter and close it. Then open
the valve a little bit so only water can come out and no beads.
4. Loosen all connections and drain exposed pipes, so that no water will be trapped. This is especially important for your UV lights!
In the spring:
1. Tighten all the connections that you loosened in the fall.
2. Move the multiport valve to the lter position and open the air release valve at the top of the lter and close the drain plug. Turn on the
pump. When water comes out of the air release valve at the top of the lter, shut it and turn o the pump. Now do a good backwash and
rinse before going to the lter mode. Back up to full capacity. During the rst few weeks of operation in the spring, it is a good idea for the
pond owner to do frequent checks of the ammonia and nitrite levels.
