Important Safety Information

• Read the entire instruction manual carefully before installation and operation.
• Vertical Installation Only: The unit must be installed vertically to prevent heating element failure (E2 error). Horizontal installation is strictly prohibited.
• Electrical Requirements: The unit operates at 3000W, 27A at 110V. A dedicated 31AMP circuit breaker and 10AWG wire gauge are required. Ensure proper grounding.
• Water Connection: Use G1/2 water connections. Tighten pipe joints with Teflon tape to prevent leaks and potential short circuits (E2 error).
• Water Flow: The water heater cannot be started without sufficient water flow. Ensure water is flowing through the unit before powering it on.
• Leakage Protection: The unit features leakage protection. Regularly inspect connections for any signs of leaks.
• Overheat Protection: Equipped with anti-overheating and anti-dry burning features. If the temperature control switch (overheat protection switch) trips, press it to restore operation.
• Automatic Power-off: The unit includes an automatic power-off function for safety.
• IPX4 Waterproof: Provides protection against splashing water.
• Intended Use: This device is primarily intended for sinks (e.g., washing hands, vegetables, dishes) and is not recommended for shower use due to its flow rate and temperature rise characteristics.

Installation Guide

Important: Ensure the power supply is disconnected before starting installation. This unit requires vertical installation only. Horizontal installation is not permitted to avoid dry heating issues.

1. Mark Drill Points: Hold the water heater against the wall in the desired vertical position and mark the points for drilling.
2. Drill Holes: Use an electric drill to create holes at the marked points.
3. Insert Expansion Tubes: Insert the plastic expansion tubes into the drilled holes.
4. Mount Water Heater: Align the water heater with the expansion tubes and tighten it securely with the provided screws.
5. Connect Cold Water Inlet: Connect the cold water supply pipe to the inlet nipple at the bottom of the water heater. Ensure a tight, leak-free connection, using Teflon tape if necessary.
6. Connect Hot Water Outlet: Connect the hot water pipe from your faucet to the outlet nipple at the top of the water heater. Ensure a tight, leak-free connection.
7. Fill System: Before connecting power, open the main water supply valve to fill the water heater and the entire plumbing system. Allow water to flow from the hot water faucet until a constant stream without air bubbles is observed. This purges air from the system and prevents dry heating.
8. Check for Leaks: Inspect all connections for any signs of water leakage. Address any leaks before proceeding.
9. Connect Power: Once the system is filled and leak-free, connect the power plug to a suitable electrical outlet.

Operating Instructions

1. Power On: After successful installation and ensuring water flow, plug in the unit. The digital display will light up.
2. Activate Heating: Turn on the water flow at your faucet. The water heater will detect the flow and begin heating. The display will show the current water temperature.
3. Temperature Control:
   • The water temperature is primarily adjusted by the water flow rate. A larger water flow results in a lower temperature, while a smaller water flow results in a higher temperature.
   • If a regulating valve is used to fix the water flow, the output temperature will also be fixed.
4. Temperature Unit Conversion: To switch the display between Celsius (°C) and Fahrenheit (°F), press and hold the power button on the unit for 6 seconds.
5. Standby Mode: When the water flow is turned off, the unit will automatically enter standby mode.

Maintenance

To ensure optimal performance and longevity of your Green Point Home Tankless Electric Water Heater, regular maintenance is recommended:

• Cleaning: Periodically wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Inspect Connections: Regularly check all water connections for any signs of leaks. Tighten connections if necessary.
• Descaling: In areas with hard water, mineral deposits can accumulate over time. Consult a qualified plumber for professional descaling if you notice a decrease in performance or water flow.
• Winterization (if applicable): If the unit is installed in an area subject to freezing temperatures and will not be used for an extended period, drain the unit completely to prevent damage from freezing water.

Troubleshooting

If you encounter issues with your water heater, refer to the following common problems and solutions:

1. No Power / Display Off:
   • Check if the power supply is normal. Ensure the unit is properly plugged into a functioning outlet.
   • If the unit is powered on, the display should light up to show the temperature. If not, check the power connection.
2. No Heating / Display Shows Marquee (Scrolling Text):
   • This indicates that water flow is not passing through the water heater, or the water pressure is too low.
   • Ensure the water inlet and outlet are correctly installed.
   • If water pressure is sufficient and there is water flow but no heating, check the turbine at the water inlet of the water heater for any obstructions.
3. Temperature Does Not Rise:
   • Overheat Protection Tripped: The temperature control switch (overheat protection switch) inside the water heater may have tripped. Press the temperature control switch to reset it.
   • Faulty Heating Pipe: If resetting the overheat protection does not resolve the issue, the heating pipe may be faulty and needs replacement.
4. Display Shows E1, E3, or E4 (Overtemperature / Sensor Failure):
   • First, turn off the power to the unit.
   • Run the machine with cold water for a period to cool it down.
   • Then, power it back on. Ensure that the water flow is not too small during normal use, as this can contribute to overheating.
5. Display Shows E2 (Heating Element Failure / Short Circuit):
   • This error often indicates improper installation, such as horizontal mounting or loose pipe joints.
   • Ensure the unit is installed vertically.
   • Check that all pipe joints are tightened securely with Teflon tape to prevent short circuits caused by water leakage.
6. Tripping Circuit Breaker:
   • Verify that the electrical circuit meets the specifications: a dedicated 31AMP (or greater) circuit breaker and 10AWG wire gauge are required.
   • An undersized circuit or wiring can cause the breaker to trip.
   • If specifications are met, a fault within the unit may be present, requiring professional inspection.
7. Water Pipe Length: The length of the water pipe at the outlet is recommended not to exceed 3 meters. Exceeding this length may cause a water pressure difference or insufficient water pressure to start the unit. If using a water tower, its height should be greater than 10 meters to ensure adequate water pressure.
