Oase BioMaster, BioMaster Thermo, BioMaster2, 250, 350, 600, 850 Manual

PRODUCT DESCRIPTION

Overview

• BioMaster 250/350/600/850: Water filtering and recirculation.
• BioMaster Thermo 250/350/600/850: Water heating, filtering and recirculation.
• For operation with freshwater or saltwater.
• While adhering to the technical specifications. (→ Technical data)

The following restrictions apply to the unit:

• Only use indoors and for aquaristic purposes in the home (not for commercial use).
• Only operate with water at a water temperature of +4°C to +35°C.

Function description
Drawn 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.

INSTALLATION AND CONNECTION

Order of tasks to be carried out:

1. Fit the unit feet (→ Fitting the unit feed)
2. Prepare the filter media (→ Cleaning/replacing the filter media)
3. As an option: OASE HeatUp Retrofitting (heater) (→ Retrofitting the heater)
4. Install the unit.
   • Install the unit next to or under the aquarium. Note the maximum head height. (→ Technical data)
5. Establish the connections (→ Establishing the con nections)

Fitting the unit feed
How to proceed:
Fig. K

• Twist the rubber feet into the openings of the con tainer base.

Retrofitting the heater

  recommended
  possible
  – not possible

Prerequisite:

• The pump is switched off. (→ Switching off the unit)

N O T E
When the filter is filled with water, water may spill when the heater is inserted.

• Take measures to collect any spillage.

How to proceed:
Fig. L

1. Unscrew the blind plug counter-clockwise and remove.
2. Push the heater into the holding ring as far as it goes.
   • Tip: Moisten the glass bulb with water before inserting.
3. Fit the heater. (→ Fitting the heater)

Establishing the connections
Assembling the suction unit
How to proceed:
Fig. M

Assembling the flow-out unit
How to proceed:
Fig. N

• Assemble the flow-out unit.
  • The water distributor can be used instead of the flow-out pipe.

Connecting the hose
Fig. O, P
The procedure is identical for the inlet (IN) and outlet (OUT).

• Fasten the suction unit and flow-out unit in the aquarium using suction cups.

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)

N O T E
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:
Fig. 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
N O T E
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.

N O T E
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:
Fig. R

1. Route each power connection cable such that it forms a drip loop.
2. Connect the power connection cable to the power supply.
   • The pump will switch on immediately.
   • Trapped 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
How 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
How to proceed:
Fig. 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 brush.
• 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.

N O T E
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)
