1. Увод
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Grundfos UP15-29SU/LC 59896776 circulator pump. The UP15-29SU/LC is a canned rotor pump designed for hot water circulation systems, featuring a maximum power input of 87W and durable stainless steel construction. It operates as an integral unit without a shaft seal, utilizing only two gaskets for sealing, and its bearings are lubricated by the pumped liquid.
Key characteristics include ceramic shaft and radial bearings, a carbon axial bearing, a stainless steel rotor can and bearing plate, and a corrosion-resistant composite (PES) impeller. The pump housing is made of stainless steel. The motor is a 1-phase type, requiring no additional motor protection.
This image shows the Grundfos UP15-29SU/LC 59896776 circulator pump, a compact unit with a red motor housing and stainless steel pump body, designed for hot water circulation systems.

- Вратите напајање пумпе.
- The pump should start circulating water, often with a quiet hum.
3.2 Нормалан рад
- The pump is designed for continuous hot water circulation, providing instant hot water at fixtures.
- The liquid temperature range for operation is 35.6 °F to 230 °F (2 °C to 110 °C).
- When connected to a thermostatic controller, the pump will operate according to the set temperature parameters, optimizing energy usage.
- The pump is known for its quiet operation. Any unusual noise should be investigated.
4. Одржавање
The Grundfos UP15-29SU/LC pump is designed for minimal maintenance due to its canned rotor design and liquid-lubricated bearings. However, periodic checks are recommended to ensure optimal performance and longevity.
- Визуелни преглед: Regularly inspect the pump and connections for any signs of leaks, corrosion, or damage.
- Провера буке: Listen for any unusual noises during operation. A sudden increase in noise could indicate an issue.
- Испирање система: If the water quality is poor, periodic flushing of the system may be beneficial to prevent buildup within the pump.
- Bushing Protection: When handling or reinstalling the pump, take care not to damage the internal bushings.
КСНУМКС. Решавање проблема
If you encounter issues with your Grundfos circulator pump, consider the following common troubleshooting steps:
| Проблем | Могући узрок | Решење |
|---|---|---|
| Pump not running / No hot water circulation | No power, tripped breaker, faulty wiring, seized impeller. | Check power supply and circuit breaker. Verify electrical connections. Consult a professional if impeller is suspected to be seized. |
| Прекомерна бука током рада | Air in the system, incorrect installation orientation, worn bearings, debris in pump. | Vent the system to remove air. Verify pump orientation (circular motor part should be horizontal). Check for debris. If noise persists, professional inspection may be needed. |
| Leaking from pump or connections | Loose connections, damaged gaskets/washers, crack in housing. | Tighten connections. Replace old or damaged gaskets/washers. If housing is cracked, pump replacement is necessary. |
| Inconsistent hot water | Thermostatic controller malfunction, partial blockage, pump cycling incorrectly. | Check thermostatic controller settings and function. Inspect system for blockages. |
If these steps do not resolve the issue, contact Grundfos customer support or a qualified plumbing professional.
