Full Pad Cleaning or Replacement
1. For units with UV, be sure to turn this off or unplug it
before servicing. Unplug the pump before opening.
2. Loosen the locking nuts that secure the tubing
connectors to the filter and remove them from the lid.
Be sure not to lose the gaskets that seal the connectors
to the filter.
3. To access the pads and bio-balls for cleaning or
replacement, the top of the filter can be removed by
taking off the clamp. Start by sliding the locking wedge
to release tension.
4. To remove the clamp completely depress the tab and
open the clamp wide enough to remove from the filter.
5. Carefully lift the lid off the tub. Be sure to not lose the
O-Ring that seals the lid and tub.
6. Filter pads can be removed and rinsed with clean water.
Replace with new pads if they are showing signs of wear.
EC2600/2600U units have two pads and the EC3900/
EC3900U units have three pads.
7. Bio-balls can be accessed by removing the plate at the
bottom. Bio-balls can be rinsed with pond water to get
larger debris from them, but do not overclean these.
This is where the beneficial bacteria grow.
8. Replace items in reverse order and install the O-ring with
lid assembly back on filter body.
9. Secure the clamp around the filter by closing the clamp
firmly and sliding locking wedge into place for a tight seal.
10. Reattach hose connections with gaskets and locking
nuts securely in place.
11. Plug in pump and UV. Observe the filter and check for
leaks.
