4.1 ການກວດສອບການຕິດຕັ້ງກ່ອນ

• Confirm your home has a standard single-pipe plumbing system.
• Ensure an electrical outlet is available under the sink where the pump will be installed.
• Turn off the main water supply and drain the hot and cold water lines at the installation point.

4.2 ຂັ້ນຕອນການຕິດຕັ້ງ

1. Mount the recirculating pump securely under the sink. Ensure it is positioned to allow for hose connections and access to the timer.
2. Connect the provided flex hoses to the hot and cold water supply lines under the sink using the included tees and flanges. Follow local plumbing codes.
3. Connect the pump to the flex hoses. Ensure all connections are tight to prevent leaks.
4. Slowly turn on the main water supply and check for any leaks. Tighten connections as necessary.
5. Plug the pump's power cord into the grounded electrical outlet.

5. ການຕິດຕັ້ງແລະການດໍາເນີນງານ

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

5.1 Setting the Programmable Timer

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 ການດໍາເນີນງານອັດຕະໂນມັດ

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. ບໍາລຸງຮັກສາ

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 ການທໍາຄວາມສະອາດ

Periodically inspect the pump and connections for any signs of leaks or corrosion. Clean the exterior of the pump with a damp ຜ້າຕາມຄວາມຕ້ອງການ. ຢ່າໃຊ້ເຄື່ອງເຮັດຄວາມສະອາດຂັດ.
