4. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
Installation of the Wilo RS25/6-3P circulation pump should only be performed by qualified personnel in accordance with local regulations and safety standards.
4.1. പ്രീ-ഇൻസ്റ്റലേഷൻ പരിശോധനകൾ
- Ensure the power supply matches the pump's requirements (~230V-50Hz).
- Verify that the installation location provides adequate space for the pump and its connections, referring to the dimensional drawing (Figure 4).
- Confirm that the pipe diameter is 25mm (1") and the connection size is 1" 1/2.
4.2. മൗണ്ടിംഗ്
- Mount the pump securely in the heating system piping. The flange distance is Ø 130mm.
- Use appropriate nuts for the 1" 1/2 connections to ensure a watertight seal.
- Ensure the pump is installed in a position that allows for proper air venting and easy access for maintenance.
4.3. വൈദ്യുതി ബന്ധം
- എല്ലാ ഇലക്ട്രിക്കൽ ജോലികളും ലൈസൻസുള്ള ഇലക്ട്രീഷ്യൻ നടത്തണം.
- Connect the pump to a grounded 230V-50Hz power supply.
- Ensure all wiring connections are secure and insulated to prevent electrical hazards.
5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
The Wilo RS25/6-3P pump features three speed settings to adapt to your heating system's requirements.
5.1. പ്രാരംഭ ആരംഭം

5.2. സ്പീഡ് തിരഞ്ഞെടുക്കൽ
The pump has a selector (typically a red knob on the motor housing, as seen in Figure 1) to choose between three operating speeds:
- വേഗത I (കുറഞ്ഞത്): 0.20 A / 46 W – Suitable for systems requiring minimal circulation or for energy saving.
- Speed II (Medium): 0.30 A / 67 W – A balanced setting for general heating requirements.
- Speed III (High): 0.40 A / 93 W – For maximum circulation and faster heat distribution.
Select the appropriate speed based on your system's design and heating demand. Adjusting the speed can help optimize comfort and energy efficiency.
6. പരിപാലനം
Regular maintenance ensures the longevity and optimal performance of your circulation pump.
- വാർഷിക പരിശോധന: Have a qualified technician inspect the pump annually for any signs of wear, leaks, or unusual noises.
- System Water Quality: Ensure the heating system water is clean and free from debris or corrosive elements. Poor water quality can lead to pump damage.
- വൃത്തിയാക്കൽ: Keep the exterior of the pump clean and free from dust and dirt to ensure proper cooling.
- വായുസഞ്ചാരം: Periodically check and vent the heating system to remove any trapped air, which can affect pump performance and cause noise.
7. പ്രശ്നപരിഹാരം
നിങ്ങളുടെ പമ്പിൽ പ്രശ്നങ്ങൾ നേരിടുകയാണെങ്കിൽ, ഇനിപ്പറയുന്ന പൊതുവായ പ്രശ്നങ്ങളും പരിഹാരങ്ങളും പരിശോധിക്കുക:
| പ്രശ്നം | സാധ്യമായ കാരണം | പരിഹാരം |
|---|---|---|
| പമ്പ് ആരംഭിക്കുന്നില്ല | No power supply, seized rotor, air in pump | Check power connection and circuit breaker. Attempt to free rotor (if accessible and safe). Vent the system. |
| പമ്പ് ശബ്ദായമാനമാണ് | Air in system, cavitation, foreign objects | Vent the system thoroughly. Check system pressure. Inspect for debris. |
| അപര്യാപ്തമായ രക്തചംക്രമണം | Incorrect speed setting, air in system, clogged pipes/filter | Increase speed setting. Vent the system. Check and clean system filters. |
| പമ്പ് ചോർന്നൊലിക്കുന്നു | Loose connections, damaged seals | Tighten pipe connections. Contact a qualified technician for seal replacement. |
If the problem persists after attempting these solutions, please contact a qualified technician or the manufacturer's support.
