3. Be certain the Purge valve is in the closed (vertical)
position;
turn the lock nut clockwise to loosen it; then
remove the rubber drain cap.
4. Attach one end of a flexible 5/8 in.(1.58cm) diameter hose
(not supplied) to the Purge valve
, and position the other
end in an appropriate basin or discharge drain. If not using
the Fluval ribbed hosing it may be necessary to use a clamp
to secure the hose in place.
5. a. First, turn the Purge valve to the open (horizontal)
position
(rotate it counter-clockwise).
b.
Then
disconnect the OUT valve:
press its release button,
and lift it from the filter lid.
6. Water will immediately begin to drain from the canister.
7. When water stops draining turn the IN valve to the open
(vertical) position for a few seconds, then close it quickly by
turning it to the closed (horizontal) position.
Repeat this
sequence two or three times to create a “tide” effect that will
force much of the debris at the bottom of the filter canister out
into the basin or discharge drain.
8. When the purge cleaning is complete turn the IN valve to the closed (horizontal) position.
Then close the Purge Valve by turning it to the vertical position. Remove the drain hose;
replace the rubber drain cap, and secure it by turning the lock nut clockwise.
9. Replace the OUT valve back in the OUT connection on the filter lid
, and press gently until it
clicks into place.
10. a. Open the IN valve.
b. Then open the OUT valve. Do not change this
sequence.
The filter should refill automatically. If it
does not, fill with 8 liters of water (as in “Set Up the
Filter, Step #7).
11. Once the water level is restored, plug the unit back in.
The filter will go through its normal start up sequence.
