CAUTION: Always unplug any appliances from an outlet when not in use, before putting on or taking off
parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
FILTER MAINTENANCE
Prior to periodic maintenance the canister must be drained.
1. Drain the filter
1. Turn the IN and OUT valves in sequence to the closed (horizontal) position.
2. Unplug the pump from the electrical power supply.
3. Remove the utility hose from the clips on the lid and position its end in an appropriate basin or
discharge drain.
4. Turn the utility valve to the open (horizontal) position by turning it counterclockwise. Then disconnect
the OUT valve.
5. 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.
2. Disassemble the unit
1. Move the filter to an appropriate area convenient for maintenance.
2. Loosen and remove the eight lid fasteners; remove the filter lid and set aside. Be careful not to damage
the inlet stem connected to the lid.
3. Using the red T-handles, lift the media baskets from the filter canister; let the T-handles fall out of their
slots, and separate the baskets.
3. Cleaning or replacing media
1. Remove all foam inserts from the media baskets and trays, rinse using aquarium or de-chlorinated tap
water, or replace with new foam, as required.
2. Rinse biological media with aquarium water, or replace, as
required.
3. Replace chemical media, as needed. Chemical media cannot be
cleaned.
4. Empty and rinse the filter canister. NEVER use soap or
detergents when cleaning the canister or rinsing the baskets
and trays, as remaining traces of cleaning products may damage
sensitive fish tissue.
5. NEVER overfill baskets. Leave at least 0.5 in. (1cm) of free space from the top of the baskets to the media, so
the baskets will fit together properly. If the red tray is present, the media at the bottom of the basket must not
exceed the height of the tray supports in the basket.
