5. Ntọala na arụ ọrụ

The Nevercold recirculating pump is equipped with a built-in programmable timer and an aquastat (temperature sensor) to manage hot water circulation.

5.1 Ịtọ oge a na-ahazi ihe

The integrated timer allows you to set specific periods during the day when the pump will activate. This ensures hot water is available during peak demand times, such as mornings and evenings, without continuous operation.

• Refer to the timer's specific instructions for setting the desired on/off cycles.
• Typically, you will push in segments on the timer dial corresponding to the hours you want the pump to operate.
• Ensure the current time is correctly set on the timer for accurate scheduling.

5.2 Ọrụ akpaaka

When the pump is activated (either by the timer or manually), it circulates water until the aquastat detects that the water temperature has reached a set hot temperature. Once the desired temperature is achieved, the pump automatically shuts off, conserving energy.

6. Nlekọta

Regular maintenance ensures the longevity and efficient operation of your recirculating pump.

6.1 Flushing for Maintenance

The system is designed for easy flushing when maintenance or replacement is necessary. Consult a qualified plumber for detailed flushing procedures, which typically involve isolating the pump, draining the lines, and flushing with appropriate solutions if scale buildup is a concern.

6.2 Nhicha

Periodically inspect the pump and connections for any signs of leaks or corrosion. Clean the exterior of the pump with a damp cloth as needed. Do not use abrasive cleaners.
