For any internal maintenance or repairs, it is recommended to contact a qualified service technician.
7. Troubleshooting
If the pump is not operating as expected, consider the following basic checks:
- No Power: Check if the pump is properly plugged into a live electrical outlet. Verify circuit breakers or fuses.
- No Flow/Low Flow: Ensure all valves in the system are open. Check for air in the system and bleed if necessary. Verify that the system pressure is within the pump's operating range.
- Unusual Noise: Air in the system or debris in the pump can cause noise. Bleed the system or, if persistent, contact service personnel.
For complex issues or if basic troubleshooting does not resolve the problem, contact a qualified service technician or the manufacturer's support for assistance.
