2. Important Safety Instructions
WARNING: Failure to follow these instructions can result in electric shock, fire, or serious injury.
- Always disconnect power to the unit before performing any service or maintenance.
- Installation must be performed by a qualified electrician in accordance with all local and national electrical codes.
- Ensure proper grounding to prevent electric shock.
- Do not operate the heater if the water pressure drops below 15kPa, as this can lead to dry burning. The unit has a built-in pressure switch for protection.
- The heater is equipped with a high-temperature protection switch that trips if the water temperature reaches 50°C due to lack of flow or blockage.
- This heater operates on 220-240V AC. For North American 110V standard, self-wiring is required with one ground wire and two live wires.
- Ensure the circulation pump is at least 1HP for proper operation.
- Do not touch the internal components or wiring unless you are a qualified professional and the power is disconnected.

4. Setup and Installation
4.1. Pre-Installation Checklist
- Verify that the power supply matches the heater's voltage (220-240V AC).
- Ensure a dedicated circuit with the required breaker size (40A for 5.5KW model) is available.
- Confirm you have a circulation pump with a minimum of 1HP.
- Gather necessary plumbing materials, including SCH40 1.5" PVC pipes and fittings.
- Choose a suitable location for the heater, ensuring it is protected from direct weather exposure and has adequate ventilation.
4.2. Plumbing Connection
The heater should be installed in line with your pool's filtration system, typically after the filter and before any chemical feeders. Ensure a circulation pump of at least 1HP is used to provide adequate water flow through the heater.
Image: Illustration demonstrating the correct connection of the pool heater with a circulation pump (≥1HP). Submersible and booster pumps are shown as incorrect examples.
Use SCH40 1.5" PVC pipes for all plumbing connections to ensure compatibility and proper flow. Secure all connections to prevent leaks.
4.3. Electrical Connection
Important: Electrical wiring must be performed by a qualified electrician. The unit requires self-wiring.
- Ensure the main power supply is OFF before beginning any electrical work.
- The pool heater operates on 220-240V. In North America (110V standard), it requires one ground wire and two live wires for proper connection.
- Connect the wires to the appropriate terminals inside the heater's electrical compartment as shown in the diagram.
- Ensure all connections are tight and secure.

5. Operating Instructions
5.1. Control Panel Overview
The Mxmoonant Pool Heater features a touchscreen display for intuitive control. The display shows the current water temperature and allows for setting the desired temperature.
Image: Close-up of the heater's touchscreen display, indicating real-time temperature, temperature range (77-122°F), and unit switch between °F and °C.
The control panel typically includes:
- Digital Display: Shows current water temperature and set temperature.
- SET Button: Used to enter temperature setting mode.
- Up/Down Arrows: Used to adjust the desired temperature.
- Flow Indicator: (Usually a light) Indicates normal water flow.
- Heating Indicator: (Usually a light) Indicates the heater is actively heating.
Image: Diagram detailing the temperature control panel, showing the flow indicator (1) and heating indicator (2). Both indicators must be ON for proper operation.
5.2. Setting the Temperature
- Ensure the circulation pump is running and there is adequate water flow through the heater.
- Press the SET button on the touchscreen. The display will likely flash the current set temperature.
- Use the Up and Down arrow buttons to adjust the desired water temperature.
- Once the desired temperature is set, the heater will automatically begin heating if the current water temperature is below the set point.
The heater operates in cycles, automatically turning on when the water temperature falls below the preset temperature and turning off when it reaches the preset temperature. For pools, a proper temperature range is typically 78-86°F (25-30°C). For hot tubs/spas, 104°F (40°C) is common.
Image: Graph showing the automatic circulation heating process, where the heater cycles around preset temperatures (e.g., 30°C/86°F for pools and 35°C/95°F for spas).
5.3. Heating Performance
The time required to heat your water depends on factors such as the volume of water, ambient temperature, and pool insulation. The 5.5KW model is ideal for approximately 700 gallons. Using hot water rather than cold water to fill a spa can prevent affecting heating performance.
Image: Table providing estimated heating times for different heater powers (5.5KW, 9KW, 11KW, 15KW, 18KW) to raise 1000 gallons by 9°F. For the 5.5KW model, this is approximately 5 hours.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Mxmoonant Pool Heater.
- Inspect Connections: Periodically check all plumbing and electrical connections for leaks or loose wiring. Tighten as necessary.
- Clean Filter: Ensure your pool's filter system is clean and functioning correctly to maintain optimal water flow through the heater. Reduced flow can trigger safety shutdowns.
- Winterization: If you live in an area with freezing temperatures, properly winterize your pool and heater to prevent damage from freezing water. Consult a pool professional if unsure.
- Heating Element: The heater features an upgraded 316 stainless steel heating element designed for durability. While generally maintenance-free, ensure proper water chemistry to prevent scale buildup.

7. Troubleshooting
This section provides solutions to common issues you might encounter with your pool heater.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater not turning on / No display | No power supply; Tripped circuit breaker; Loose electrical connection. | Check power source and circuit breaker. Ensure all electrical connections are secure. Consult a qualified electrician. |
| Heater turns off automatically / Error code | Low water flow (pressure switch activated); High temperature protection activated (lack of flow/blockage). | Ensure circulation pump is running and filter is clean. Check for blockages in plumbing. Verify water pressure is above 15kPa. |
| Water not heating to desired temperature | Incorrect temperature setting; Insufficient heating time for water volume; Poor pool insulation; Low ambient temperature. | Verify set temperature. Allow more time for heating, especially for larger volumes or colder starting temperatures. Consider pool cover/insulation. |
| Flow indicator not lit | No water flow; Insufficient water pressure; Faulty flow sensor. | Check if circulation pump is operating. Ensure water level is adequate. Clean filter. If problem persists, contact support. |
| Heating indicator not lit (but flow is normal) | Desired temperature already reached; Faulty heating element; Electrical issue. | Check if water is already at set temperature. If not, and flow is normal, there may be an internal fault. Contact support. |
