Safety Information
OASE has built this unit according to the state of the art and valid safety regulations. However, hazards can emanate from this unit if it is used improperly, not in accordance with its intended use, or if safety instructions are ignored.
For safety reasons, children and young persons under 16 years of age, as well as persons who cannot recognize possible danger or are not familiar with these operating instructions, are not permitted to use the unit. Keep children under supervision to ensure they do not play with the unit.
Hazards from Water and Electricity Combination:
The combination of water and electricity can lead to death or severe injury from electrocution if the unit is incorrectly connected or misused. Prior to reaching into the water, always switch off the mains voltage to all units used in the water.
Correct Electrical Installation:
- Electrical installations must meet national regulations and may only be carried out by a qualified electrician.
- A person is considered a qualified electrician if, due to their vocational education, knowledge, and experience, they are capable of and authorized to judge and carry out the commissioned work. This includes recognizing hazards and adhering to regional/national standards.
- For your own safety, consult a qualified electrician.
- The unit may only be connected when the electrical data of the unit and the power supply coincide. Unit data is found on the type plate, packaging, or in this manual.
- Ensure the unit is fused for a rated fault current of max. 30 mA by means of a fault current protection device.
- Extension cables and power distributors must be suitable for outdoor use.
- Ensure the power connection cable cross-section is not smaller than that of the rubber sheath (e.g., H05RN-F). Extension cables must meet DIN VDE 0620.
- Protect plug connections from moisture.
- Only plug the unit into a correctly fitted socket.
Safe Operation:
- Never operate the unit if electrical cables or housing are defective.
- Do not carry or pull the unit by its electrical cable.
- Route all cables to exclude damage and tripping hazards.
- Never open the unit housing or components unless explicitly required by instructions.
- Only use original spare parts and accessories.
- Never carry out technical modifications.
- Only have repairs carried out by OASE authorized service points.
- Power connection cables cannot be replaced. If damaged, the unit or component must be disposed of.
- Only operate the unit if no persons are in the water.
- Keep the socket and power plug dry.
Important! The unit is equipped with a permanent magnet. The magnetic field may affect the function of pacemakers.
Installation
Diagram Description: Diagram A shows how to attach a hose to the pump's stepped adapter. Diagram B illustrates the assembly process in four steps: 1. Attaching the hose adapter to the pump. 2. Securing the hose with a clip. 3. Placing the pump unit into the strainer casing. 4. Closing the strainer casing.
Procedure:
- Cut the stepped hose adapters so the connection opening matches the hose diameter to avoid pressure loss.
- At the filter pump, push or turn the hose onto the stepped hose connection, secure with hose clips, and screw onto the filter pump connection thread.
- Place the unit in the pond horizontally on firm, sludge-free ground.
- Ensure the unit is completely covered with water, at a maximum of 2 meters below the surface.
Start-up
Attention! Sensitive electrical components. Possible consequence: The unit will be destroyed. Protective measure: Do not connect the unit to a dimmable power supply.
Attention! The pump must never run dry. Possible consequence: The pump will be destroyed. Protective measure: Check the water level at regular intervals. Always place the unit below water level.
Attention! The installed temperature monitor automatically turns the pump off if it is overloaded. The pump automatically switches on again once the motor has cooled down. Risk of accident!
Connecting the Power Supply:
- Switching on: Connect the power plug to the socket. The unit switches on immediately when power is established.
- Switching off: Disconnect the power plug.
Maintenance and Cleaning
Attention! Dangerous electrical voltage. Possible consequences: Death or severe injury. Protective measures: Prior to reaching into the water, disconnect the power supply to all units used in the water. Disconnect the power plug prior to carrying out work on the unit.
If necessary, clean the unit with clear water using a soft brush. Never use aggressive cleaning agents or chemical solutions, as they could attack the housing surface or impair function. In the event of stubborn furring (calcium deposits), a common household cleaner free from vinegar and chlorine can be used. Subsequently, clean the pump thoroughly using clear water.
Cleaning the Unit:
- Open the strainer casing and remove the pump (B).
- Unscrew the pump lid and remove the impeller.
- Clean all components using clean water and a brush.
- After cleaning, reassemble in reverse order. Insert the pump into the strainer casing.
- For the 1500-2500 series, ensure correct seating of the rubber buffers used for the pump bearing.
- Route the connection cable so it cannot be pinched.
- Refit the strainer lid and close.
Malfunctions
| Malfunction | Cause | Remedy |
|---|---|---|
| The unit is not operating | No mains voltage | Check mains voltage |
| Insufficient delivery rate | Impeller blocked | Clean impeller |
| Strainer casing clogged | Clean strainer casing | |
| Excessive pressure losses in the hoses | Reduce hose length and connecting parts to a minimum, route hoses as straight as possible | |
| Unit switches off after a short running period | Water temperature too high | Note maximum water temperature of +35°C |
Disposal
Do not dispose of this unit with domestic waste! For disposal purposes, please use the return system provided. Disable the unit beforehand by cutting off the cables.
Storage/Over-wintering
