Intended use

BioMaster 250/350/600, BioMaster Thermo
250/350/600, referred to as "unit", may only be used
as specified in the following:

• BioMaster 250/350/600: Water filtering and recir-

culation.

• BioMaster Thermo 250/350/600: Water heating,

filtering and recirculation.

• For operation with freshwater or saltwater.

• Operation under observance of the technical data.

The following restrictions apply to the unit:

• O

nly use indoors and for aquaristic purposes in the

home (not for commercial use).

Function description

Dr

awn in by a pump in the unit head, the water first
flows through the pre-filter then from the bottom to
the top through the superimposed layers of filter me­dia. The water then flows back into the aquarium via
the flow-out pipe or water distributor.

Foam filters with different pore densities, and Hel-X
bio-elements serve as filter media.

In units with heater, the water is heated during its pas­sage through the filter system.

ACCESSING THE UNIT

NOTE

The following applies to all units with heater:

• Adhere to the rules for careful handling. (→ Careful

handling of the heater)

Careful handling of the heater

CAUTION

Hot surface!

Risk of burns when touching the glass bulb.

• Switch off the heater and allow it to cool down be-

fore removing it from the water.

CAUTION

Risk of breaking the glass!

The glass bulb of the heater can break and cause cuts.

• Take care when handling the heater.

• Allow the heater to cool down first. Do not immerse

it in cold water or pour cold water over it.

COMMISSIONING/START-UP

For initial start-up or after thorough cleaning, it is nec­essary to expel air from the filter system. When the
container, suction unit and hose are free of trapped
air, the pump can convey the water by itself through
the filter system. (→ Expelling air from the filter sys­tem)

NOTE

Thoroughly rinse out all filter material with warm tap
water before using for the first time in order to remove
any soiling. (→ Cleaning/replacing the filter media)

Expelling air from the filter system

Prerequisite:

• The pump is switched off. (→ Switching off the unit)
How to proceed:

 Q

1. Press the suction button and release it until the wa­ter flows out of the tank into the filter.
– The filter is completely flooded when water

emerges from the flow-out unit.

Switching on the unit

NOTE

Ensure that the pump never runs dry!

The pump will be destroyed.

• Regularly check the water level and circulation in
the filter and in the aquarium.

NOTE

Risk of fire due to the hot surface of the heater!

The heater and filter can be destroyed by the gener­ated heat.

• Do not switch the heater on until the filter is com­pletely filled with water, switched on and the water
is continuously circulated.

• Switch off the heater and allow it to cool down be­fore removing it from the water.

How to proceed:
 R

1. Route each power connection cable such that it
forms a drip loop.

2. Connect the power connection cable to the power
supply.
– T

he pump will switch on immediately.

– T

rapped air in the filter can cause noise. The
trapped air escapes shortly after the pump starts
up.

3. Unit with heater: Set the water temperature on the

heater and switch on the heater. (→ Heater opera­ting manual).

Switching off the unit

H

ow to proceed:

• Disconnect the unit from the power supply

• Unit with heater: Disconnect the unit and heater

from the power supply

Setting the flow rate

H

ow to proceed:

 S

• Move the lever on the connection unit to set the de­sired flow rate
– "

LOCK": Maximum flow rate

– "

UNLOCK": No flow, the outlet is closed.

MAINTENANCE AND CLEANING

• If necessary, clean with clear water using a soft
br

ush.

• Do not use cleaning agents or chemical solutions.
We recommend using OASE PumpClean for remov­ing calcium deposits.

• Cleaning and replacement cycles for filter media are
dependent on the size of the aquarium and the
number of fish. Therefore, it is necessary to clean
and replace the filter media as required to ensure
optimum filter performance.

• If there are several foam filters: Clean or replace the
foam filters at different times. This saves enough
useful bacteria to ensure good biological filtration
of the water.

NOTE

Thoroughly rinse out all filter material with warm tap
water before using for the first time in order to remove
any soiling. (→ Cleaning/replacing the filter media)
