MAINTENANCE PURGE VALVE DRAINING
EN-17
WARNING:
ALWAYS DISCONNECT ALL APPLIANCES IN THE AQUARIUM FROM ELECTRICITY SUPPLY
BEFORE PLACING HANDS IN THE WATER, BEFORE PUTTING ON OR TAKING OFF PARTS, AND
WHENEVER THE FILTER EQUIPMENT IS BEING INSTALLED, MAINTAINED OR HANDLED.
Filter media must be periodically replaced or cleaned in accordance with instructions on individual
packages. Prior to periodic media care the FX5 filter canister must be drained.
The FX5 filter offers you two methods to drain the canister:
• Option 1: Purge Valve Draining
• Option 2: Filter Pump Draining
Purge Valve Draining
To use the purge valve to drain the water from the filter canister you will need a 5/8” (1.58cm)
flexible drain hose (not supplied) that is long enough to reach from the canister to a drain or basin.
Fluval ribbed hosing item number A-20015 (sold separately) is recommended as it will secure tightly
to the purge valve using the lock nut connector.
1. Unplug the pump from the electrical power supply.
2. Turn the IN and OUT valves to the closed (horizontal) position.
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. Be sure the
hose is secured to the purge valve. If not using the Fluval
ribbed hosing it may be necessary to use a clamp to secure
the hose in place.
5. First, turn the Purge valve to the open (horizontal) position by turning it counter-clockwise.
Then disconnect the IN valve:
press its release button, and lift it from the filter lid. It is a good
idea to have a cloth handy as some water will escape when removing the AquaStop Valve.
6. Water will immediately begin to drain from the canister.
Since this is a gravity fed method,
water will stop draining once the water level in the canister and drain bucket equalize. Once
this happens simply close the valve and empty the bucket. Repeat the draining process until
enough water is removed to make the canister light enough to carry to your work area.
7. Once a sufficient amount of water has been removed, close the purge valve and disconnect
the drain hose.
Replace the rubber drain cap and secure with the locknut, turn the locknut
counter clockwise to secure the drain cap in place. Disconnect the OUT valve and move to an
appropriate work area.
