USING THE BACKWASH

Whilst the filter is still functioning, connect tubing to the backflush outlet of the filter. You can divert the dirty water

into a garden bed or into a drain. Turn the valve on the backwash outlet to open.

• Now turn the backwash arrow shaped dial on the

top of the filter to "clean" mode. (The arrow will face

towards the ball valve backwash outlet). The water

from the normal outlet will now be diverted through

the backwash outlet.

• Turn the cleaning handle anti-clockwise on the filter

several times (24-36 times) or until the water exiting

the backflush outlet runs clean. This squeezes the filter

sponges and cleans them mechanically.

• Maintain the filter sponge regularly according to how

quickly the sponge gets clogged. When the flow starts

to be reduced, check and clean if necessary. This

depends on your water volume and how many fish you

are keeping. Some may have to do this weekly.

FULLY DISASSEMBLE & RINSE

Turn off your pump and disconnect the power cord from any electrical source. Undo the threaded inlet and outlets

hosetails from the filter, unclip the lid clamp and carefully remove the lid.

• Take care not to lose or damage the O'ring seal.

Unscrew the clear locking screw at the bottom of the

filter sponge layers (or the black base plate on the

bigger models). Undo the screw that holds the S/Steel

shaft in place and remove the base plate. Now remove

the foam sponge rings from off the centre cores and

rinse them in dechlorinated water or pond water.

• Be sure to thoroughly squeeze the sponges to remove

sludge.

• Remove the high efficiency bio media cassette (in

the larger models) from the bottom of the filter

canister. Only remove any excess brown sludge from

the biospheres. You should not remove all of this

brown matter as this is the beneficial bacteria, which

is essential in the breakdown of toxic waste from your

pond.

Firmly push the lid back onto

the canister. Fasten the lid

clamp in place and reconnect

the inlet and outlet hoses.

The best time to physically remove and clean your filter

is when completing a 20% water change, as you can

use the pond water you are discarding to clean all of

the parts of your spongers. Using tap water will kill the

good beneficial bacteria, found in filter sponges, with

the chlorine that is found in tap water.

• You can help boost the biological function of your filter

sponge with a bacterial additive. This is available from

your local stockist.

• Now clean out the canister of your filter and any debris

from the lid of the filter and then reassemble. First

reassemble the partially cleaned bio media cassette

into the canister. Then insert lid with the foam sponges

installed onto the centre core. The Foam sponges

should alternate from Blue to Yellow.

• Now put the lid back in place, taking care to locale the

O'ring in the correct position. See diagram. To lubricate

the O'ring use a food safe grease. Aquatec Equipment

recommends the use of Inox MX6.

Now plug the pump and

filter UV light back in, turn

on, and sit back and enjoy

your watergarden.
