PRODUCT DESCRIPTION

Intended use

BioMaster 250/350/600/850, BioMaster Thermo 250/350/600/850, referred to in the following as "unit", may only be used as specified in the following:

• 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
• Operation under observance of the 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 +39°F to +95°F

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 sealed filtration pathways to ensure water flows through all the superimposed layers of filter media. The water then flows back into the aquarium via the spray bar or water distributor. Filter foams with varying pore densities, and Hel-X Biomedia serve as filter media.
In units with heater, the water is heated during its passage through the filter system.

Establishing the connections

Assembling the inlet assembly

How to proceed:
M

• Assemble the inlet assembly.
  1. Install intake assembly by connecting the inlet strainer, adapter, and inlet tube
  2. Attach assembled parts to the adjustable inlet adapter
  3. Screw locking nut onto adjustable inlet adapter

COMMISSIONING/START-UP

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

Expelling air from the filter system

Prerequisite: The unit is unplugged. ( Switching off the unit)

How to proceed:
P

1. Press the priming 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 outlet assembly.

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 plug in the heater until the filter is completely filled with water, plug in and the water is continuously circulated.
• Unplug the heater and allow it to cool down before removing it from the water.

How to proceed:
Q

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 plug in the heater. ( Heater instruction 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

MAINTENANCE AND CLEANING

• If necessary, clean with clear water using a soft brush.
• Do not use cleaning agents or chemical solutions.
• 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 filter foams: Clean or replace the filter foams 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)

IMPORTANT SAFETY INSTRUCTIONS

READ AND FOLLOW ALL SAFETY INSTRUCTIONS!
Keep these instructions in a safe place.

SAFETY INFORMATION

This unit can be used by children aged 8 and above and by persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they are supervised or have been instructed on how to use the unit in a safe way and they understand the hazards involved. Do not allow children to play with the unit. Only allow children to carry out cleaning and user maintenance under supervision. Disconnect the power plug before carrying out any work on the unit.

To guard against injury, basic safety precautions should be observed, including the following:

• 
  To avoid possible electric shock, special care should be taken since water is employed in the use of aquarium equipment. For each of the following situations, do not attempt repairs by yourself; return the appliance to an authorized service facility for service or discard the appliance
• Unplug all units in the aquarium and disconnect the power plugs of all units before reaching into the water or moving/cleaning the unit.
• 
  Risk of Electric Shock - Don't use the pump when there are people in the water.
• 
  This unit has been evaluated for use with water only.
• 
  Never operate the unit if either the electrical cables or the housing are defective!
• Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
• Do not carry or pull the unit by its electrical cable.
• If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the appliance rating may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
• Don't attempt to open the pump/motor enclosure.
• In case of "retrofitting" operation, please carefully read and follow the content of this manual as well as heater instruction manual.
• Route cables/hoses such that they are protected from damage and do not present a tripping hazard.
• Only open the unit housing or its attendant components, when this is explicitly required in the operating instructions.
• 
  Only carry out work on the unit that is described in this manual. If problems cannot be overcome, please contact an authorized customer service point or, when in doubt, the manufacturer.
• Only use original spare parts and accessories for the unit.
• 
  Never carry out technical modifications to the unit. Don't cut the cord or remove the plug from the cord.
• Power connection cables cannot be replaced. If a cable is damaged, dispose of the respective unit or components.
• The impeller unit in the pump contains a magnet with a strong magnetic field that may affect the operation of pacemakers or implantable cardioverter defibrillators (ICDs). Always keep magnets at least 0.7 ft. away from implanted devices.

Electrical connection

• Read and observe all the important notices on the appliance.
• In case of retrofitting, please respect the recommended power shown in the table from the "Retrofitting the heater" section using only OASE HeatUp heaters.
• Only connect the unit if the electrical data of the unit and the power supply coincide. The unit data is to be found on the unit type plate, on the packaging or in this manual.
• Protect the plug connections from moisture.
• Only plug the unit into a correctly fitted socket.
• Do have all electrical outlets installed and serviced by a licensed electrician.
• 
  Do disconnect the pump from the electrical outlet at the first sign of any problem.
• 
  If the plug or receptacle does get wet, DON'T unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then, unplug and examine for presence of water in the receptacle.
• 
  Don't pinch, twist or damage the electrical cord. A minor cut even if only in the outer shell could allow water to reach the motor enclosure and damage the pump. If you notice any damage to the cord remove the pump and store in a dry place. Consult any damage to the electrical cord will void all warranties and could cause serious electrical shock hazard.
• To avoid the possibility of the appliance plug getting wet prevent water from dripping onto plug. A "drip loop," shown in the figure below, should be arranged by the user for each cord connecting an aquarium appliance to a receptacle. The "drip loop" is that part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water traveling along the cord and coming in contact with the receptacle.
