4. Opsætning og installation

The recirculating pump system is designed for straightforward installation. Follow these steps carefully:

4.1. System overview

Billede 4.1: Diagram illustrating the typical installation of the recirculating pump on the hot water outlet of a tank water heater and the bypass sensor valve under the sink.

The pump is installed on the hot water outlet of your tank water heater. The sensor valve is installed under the sink at the fixture furthest from the water heater. This creates a loop for hot water circulation.

4.2. Installationstrin

1. Turn off Water and Power: Locate your water heater and turn off both the main water supply and the power to the water heater.
2. Drain Hot Water Line: Open a hot water faucet in your home to relieve pressure and drain some hot water from the lines.
3. Install Recirculating Pump:
   • Connect the recirculating pump to the hot water outlet of your tank water heater. Ensure all connections are secure and sealed with Teflon tape.
   • The pump should be installed in an accessible location.
4. Install Sensor Valve:
   • At the faucet furthest from the water heater, locate the hot and cold water supply lines under the sink.
   • Install the 304 Stainless Steel Sensor Valve between the hot and cold water supply lines using the provided PEX supply lines and adapters. The valve is designed to allow hot water to circulate back to the water heater via the cold water line when the temperature drops below 104°F.
   • Ensure the flow direction indicated on the valve (HOT → COLD) is correct.
5. Sikre komponenter: Use the provided pipe clamps and self-tapping screws to secure the PEX supply lines and other components as needed, preventing movement and strain.
6. Genopret vand og strøm: Once all connections are secure and checked for leaks, slowly turn on the main water supply. Bleed air from the system by opening hot water faucets until water flows smoothly. Finally, restore power to the water heater and the recirculating pump.

Billede 4.2: Diagram illustrating the thermal bypass technology of the one-way sensor valve, showing how hot water is directed to the cold water line for recirculation without affecting the cold water faucet.

Billede 4.3: Simplified diagram showing the hot and cold water lines under a sink with the sensor valve installed, indicating the ease of installation.

5. Betjeningsvejledning

The Moonshan recirculating pump features a programmable timer for efficient operation.

5.1. Timerstyring

Billede 5.1: Close-up of the programmable timer on the recirculating pump, showing how to set the current time and timer mode for scheduled hot water delivery.

The integrated timer allows you to schedule the pump's operation to align with your hot water usage patterns. This ensures hot water is available when needed, reducing energy consumption during off-peak hours.

• Indstilling af aktuel tid: Rotate the outer dial to align the current time with the arrow indicator.
• Setting Programmed Cycles: Use the small pins around the dial to set ON/OFF periods. Push pins outwards for ON, inwards for OFF. Each pin typically represents 15 minutes.

5.2. Driftstilstande

Billede 5.2: Illustration of the three operating modes: Always On, Timer Mode, and Always Off, allowing users to select based on their needs.

The pump typically offers three modes of operation:

• Altid tændt: The pump runs continuously, providing instant hot water at all times. This mode consumes more energy.
• Timertilstand: The pump operates according to the schedule set on the programmable timer. This is the recommended mode for energy efficiency.
• Altid slukket: The pump remains off. Hot water will only be available after the traditional wait time.

Select the desired mode using the switch or dial on the pump unit.

6. Vedligeholdelse

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

6.1. Sensor Valve Filter Screen Cleaning

Billede 6.1: Diagram showing the replaceable filter screen within the sensor valve, designed to block impurities and prevent clogging.

The 304 Stainless Steel Sensor Valve includes a replaceable filter screen on the hot water port. This screen prevents impurities and particles from entering and clogging the valve.

• Frekvens: Inspect and clean the filter screen every 6-12 months, or more frequently if you notice reduced hot water flow or increased noise from the valve.
• Procedure:
  1. Turn off the water supply to the sensor valve.
  2. Carefully disconnect the hot water line from the sensor valve.
  3. Fjern filterskærmen.
  4. Rinse the screen under running water to remove any debris. For stubborn deposits, a soft brush may be used.
  5. Reinsert the clean filter screen and reconnect the hot water line.
  6. Slowly restore the water supply and check for leaks.

6.2. Generelt eftersyn

• Kontroller jævnligt alle forbindelser for utætheder.
