Installation Guide
Professional Installation Required: Installation of this electric water heater must be performed by a certified plumber or electrician to ensure compliance with all local codes and safety standards.
Unpacking
- Carefully remove the water heater from its packaging.
- Inspect the unit for any signs of damage during transit. Do not install if damaged.
- Retain packaging materials for potential future transport or returns.
Mounting
- Select a suitable wall location capable of supporting the full weight of the water heater when filled with water (approx. 75 kg + 26 kg = 101 kg).
- Ensure adequate clearance around the unit for maintenance and ventilation.
- Mount the water heater securely using appropriate wall anchors and brackets (not specified if included, assume standard practice).
Water Connections
- Connect the cold water inlet to the designated port (usually marked blue or 'C').
- Connect the hot water outlet to the designated port (usually marked red or 'H').
- Install the provided safety valve on the cold water inlet line. Ensure proper drainage for the safety valve discharge.
- Use appropriate plumbing fittings and sealants to prevent leaks.
Electrical Connection
- Ensure the main power supply is OFF at the circuit breaker before making any electrical connections.
- Connect the water heater to a dedicated 230V / 50Hz electrical circuit, protected by a suitable circuit breaker and residual current device (RCD).
- The appliance comes with a European plug. Ensure the outlet is compatible or have a qualified electrician install a suitable connection.
- Verify all electrical connections are secure and correctly wired according to local electrical codes.
Filling the Water Heater
- Before switching on the power, open a hot water tap in your home to allow air to escape.
- Slowly open the cold water supply valve to the water heater.
- Allow the water heater to fill completely until water flows steadily from the open hot water tap.
- Close the hot water tap.
- Check all water connections for leaks.
Operating Instructions
Initial Start-up
- After filling the water heater and checking for leaks, switch on the electrical power supply at the circuit breaker.
- The water heater will begin heating the water to the factory preset temperature or the last set temperature.
Temperature Adjustment
The water heater features a control dial, typically located at the bottom front of the unit (as seen in the product image).
- Rotate the dial clockwise to increase the water temperature.
- Rotate the dial counter-clockwise to decrease the water temperature.
- For energy efficiency and safety, it is recommended to set the temperature between 55°C and 60°C (130°F - 140°F) to prevent bacterial growth while minimizing scalding risk and energy consumption.
Normal Operation
The water heater will automatically maintain the set water temperature. The heating element will cycle on and off as needed.
The "fast heating" feature ensures quick recovery of hot water supply. The "low oxygen safety shut-off" provides an additional layer of safety.
Maintenance and Care
Regular maintenance ensures the longevity and efficient operation of your Atlantic Cube water heater. Always disconnect the power supply before performing any maintenance.
Annual Inspection
- It is recommended to have a qualified professional inspect the water heater annually.
- This inspection should include checking the anode rod (if replaceable, to prevent corrosion), inspecting the safety valve, and flushing the tank to remove sediment buildup.
Descaling
Depending on water hardness in your area, mineral deposits (scale) can build up inside the tank and on the heating element. This can reduce efficiency and lifespan.
- Descaling should be performed by a qualified technician.
- The copper heating element with O'PRO system is designed to extend the appliance's lifespan by reducing corrosion and scale buildup.
Exterior Cleaning
- Clean the exterior of the water heater with a soft, damp cloth.
- Do not use abrasive cleaners or solvents, as these can damage the ceramic finish.
Draining the Water Heater (for extended absence or freezing temperatures)
- Turn off the electrical power supply to the water heater.
- Close the cold water supply valve to the water heater.
- Open a hot water tap in your home to release pressure.
- Connect a hose to the drain valve at the bottom of the water heater and direct it to a suitable drain.
- Open the drain valve and allow the tank to empty completely.
- Once drained, close the drain valve and hot water tap.
Troubleshooting Guide
This section addresses common issues you might encounter. For problems not listed here or if solutions do not work, contact a qualified technician.
No Hot Water
- Check Power Supply: Ensure the circuit breaker for the water heater is ON.
- Thermostat Setting: Verify the temperature dial is set to a desired temperature.
- Thermal Cut-out: The automatic thermal protection may have tripped. This usually requires a technician to reset and diagnose the cause.
- Heating Element Failure: The heating element may have failed and requires replacement by a qualified technician.
Insufficient Hot Water
- Temperature Setting: Increase the temperature setting on the control dial.
- High Demand: Excessive hot water usage may temporarily deplete the tank. Allow time for recovery.
- Sediment Buildup: Sediment in the tank can reduce efficiency. Annual flushing is recommended.
- Partially Failed Element: One part of a dual element (if applicable) might have failed. Requires professional inspection.
Leaks
- Connection Points: Check all plumbing connections for tightness. Tighten if necessary.
- Safety Valve: The safety valve may discharge small amounts of water during heating due to thermal expansion. This is normal. If continuous or excessive, check water pressure or valve function.
- Tank Leak: A leak from the tank itself indicates a serious issue and usually requires replacement of the unit. Contact a professional immediately.
Unusual Noises
- Popping/Rumbling: Often caused by sediment buildup in the tank, which can trap water and cause it to boil. Flushing the tank may resolve this.
- Hissing: May indicate a small leak or water dripping onto a hot surface.
