(31)

Open all EZ clips and remove the pump head from the canister.

(32)

In order to clean the pump chamber, turn the pump head upside down and open the pump
cover by turning it anti-clockwise.

(33)

Then remove the pump cover, impeller and shaft.

(34)

Thoroughly clean pump parts, impeller chamber and cooling channel with EHEIM cleaning set
(order no. 4009580). Carefully rinse off shaft (danger of breakage!), then put impeller back to-
gether again and insert into proper position.

Pay attention to the correct installation of shaft, bushings and pump cover. Lock pump cover
by turning clockwise.

Filter media:

Remove filter pads and containers from the canister. Thoroughly wash out the

filter media with used aquarium water – until no more clouding can be seen.

The fine filter pad (white) serves as mechanical fine filtration and should only be used once,
since adhering dirt particles cannot be washed out completely. Use new pad, (order no.
2616225).

The blue filter pad (1 x included in set, order no. 2616220) can be reused up to

2 - 3 times.

Rinse thoroughly before using.

Tip:

When renewing the SUBSTRAT media, retain 1/3 of used filter medium and mix with new

material to speed-up bacteria recolonization.

Wash out the filter canister and then place the media containers back in position. Press the
first one down to the support frame, then insert the second one as far as it will go. In the pro-
cess, the pipe flow-through openings of the media containers must lie on top of each other,
and the rubber seals must be correctly fitted on the openings so as to achieve an hermetic
seal.

Attention:

Fine filter pad (white) should

not

be placed under the retractable handle of the

media container.

Place the new filter pad on the top container. Check to ensure that the sealing gasket of
the pump head fits properly and is clean. Then lightly lubricate the sealing gasket of the
pump head with Vaseline. Place the pump head on the filter canister, close the EZ clips and
place the filter into the cabinet.

Examine both o-rings on the double tap connector for damage and correct fitting and lightly
grease them with Vaseline; insert and lock in place. After both of the tap levers on the inte-
grated double tap connector have been opened (

position), the filter will automatically fill

up again with water and be ready for operation. Put the filter into operation by connecting the
mains plug.

Note:

All hose connections must be checked at regular intervals for correct fitting.

Attention:

Filter must always be operated in an upright position only.

Thermofilter:

(37)

Wash out the filter canister. Periodically check the heating element for dirt deposits and
clean if necessary.

Do not bend the heating element. Do not submerge the filter canis-

ter underwater. Ensure heater electrics do not come into contact with splashing water.

Place media containers back into the canister, as described above. Connect the pump’s
plug (from the pump head) into the mains socket.
