3.3 Електрични прикључак
Connect the pump to a suitable power supply according to the pump's specifications and local electrical codes. Ensure the voltage and frequency match the pump's requirements. A residual current device (RCD) with a tripping current of no more than 30 mA is recommended for additional safety.
3.4 Прикључак цеви
Connect the discharge pipe to the pump outlet. Ensure all connections are watertight and free from leaks. Use appropriate sealing materials. The pipe diameter should be sufficient to minimize pressure loss.
4. Упутство за употребу
4.1 Прво покретање
Before starting the pump, ensure it is fully submerged in water. Connect the power supply. The pump should start automatically if equipped with a float switch, or manually if controlled by an external switch. Monitor the pump for unusual noises or vibrations during the first few minutes of operation.

- Check the pump's intake for blockages from debris.
- Ensure all pipe connections remain secure and leak-free.
5.2 Чишћење
If the pump's performance decreases, it may be due to blockages. Disconnect power, remove the pump, and clean the intake screen and impeller area. Use clean water and a soft brush. Do not use harsh chemicals.
5.3 Зимовање
If the pump is installed in an area subject to freezing temperatures and will not be used, it must be removed from the water and stored in a frost-free environment. Drain all water from the pump and pipes to prevent damage from ice expansion.
