RESIN PACK & FILTER EXCHANGE
Resin Pack Exchange
1. Turn off the recirc pump and water supply to the Silex system.
2. Open the air vents located in the center of the cover plates.
3. Place a container under the drain valves located on the bottom plates of
the system. Open the valves and allow the water to drain into the
container. The container may be emptied at a drain.
4. Remove the cover plates by unscrewing the black knobs located at each
corner of the cover plates.
5. Pull the exhausted resin pack part of the way out of the column and lay it
over the top of the system.
NOTE: If the drain valve located on the bottom plate is not open, a vacuum will
be created making it difficult to remove the resin pack.
6. Slowly pull the exhausted pack over the side of the column while sliding it
out of the column and into the plastic sleeve that it was shipped in.
7. Remove the new resin pack from the shipping box and open the tied end
of the plastic sleeve. Stretch the resin pack over your arm to elongate
the pack. Feed the pack into the column allowing it to slide out of the
plastic sleeve. Save the plastic sleeve for the return shipment of the resin
pack at the next exchange. Close the drain valve.
8. Carefully wipe the O-rings and the grooves on the top plate and cover
plate to remove any debris from the surfaces that must seal together.
9. Replace the cover plates and tighten the knobs. To ensure proper
tightening and a good seal, tighten the knobs in opposite corners
simultaneously. Repeat for the other two corners.
10. Turn on the water supply to the Silex system and remove trapped air by
loosening the air vents located in the center of the cover plates. Tighten
the air vents when water begins to escape through the vent. This ensures
that all of the air has been removed from the system and maximizes the
life and efficiency of the resin packs.
11. Allow water to run through the system for 1 minute prior to placing the
Silex system in service.
