Safety Information
Always observe the following safety precautions to reduce the risk of injury or damage:
- Installation and maintenance must be performed by qualified personnel only.
- Ensure the power supply is disconnected before any work on the appliance.
- Do not operate the water heater if it is damaged or malfunctioning.
- Ensure proper grounding to prevent electrical shock.
- Do not block ventilation openings.
- Keep flammable materials away from the water heater.
Product Overview
The Atlantic Zeneo water heater is designed for efficient and reliable hot water production. Key features include:
- Dynamic ACI Hybrid Anti-Corrosion Protection: Combines a titanium anode with a magnesium coating for enhanced tank protection against corrosion, adapting to various water types.
- Reinforced Insulation: Contributes to energy savings by minimizing heat loss.
- Electronic Thermostat: Ensures stable water temperature and precise control.
- Steatite Heating Element: Protected from direct contact with water, reducing limescale build-up and simplifying maintenance.
- Bi-metallic Dielectric Connector: Included to prevent galvanic corrosion at pipe connections.
- Front Terminal Block: For easier electrical connections.
- Accelerated Heating: Designed to reduce the time required to heat water.
- Dry-Heating Protection Function: Prevents the heating element from operating without water in the tank.
Setup and Installation
Proper installation is crucial for the performance and longevity of your water heater. Consult a qualified professional for installation.
Pre-Installation Checks:
- Verify that the installation location can support the weight of the full water heater (approx. 250 kg).
- Ensure adequate space for maintenance and ventilation around the unit.
- Confirm that the electrical supply matches the water heater's requirements (230V, 2200W, monophase).
Installation Steps (Summary):
- Mount the wall bracket securely to a load-bearing wall using appropriate fasteners.
- Carefully lift and hang the water heater onto the wall bracket.
- Install the supplied bi-metallic dielectric connector on the cold water inlet.
- Connect the cold water supply to the inlet and the hot water outlet to your plumbing system.
- Install a safety group (pressure relief valve) on the cold water inlet, ensuring it is properly drained.
- Connect the electrical wiring to the front terminal block, ensuring proper grounding.
- Fill the tank with water before connecting to the main power supply.
- Check for leaks and verify proper operation.
Operating Instructions
Once installed and filled, operating your Atlantic Zeneo water heater is straightforward.
Initial Start-up:
- Ensure the tank is completely filled with water by opening a hot water tap until water flows freely.
- Connect the water heater to the main electrical supply.
- The electronic thermostat will automatically begin heating the water to the factory preset temperature.
Temperature Adjustment:
Refer to the control panel on the unit for temperature adjustment. Typically, a dial or buttons allow you to set the desired water temperature. Avoid setting the temperature too high to prevent scalding and save energy.
Energy Saving Tips:
- Set the temperature to a comfortable level (e.g., 55-60°C) rather than the maximum.
- Consider using a timer if your unit supports it, to heat water during off-peak electricity hours.
- Ensure the unit is well-insulated, especially if installed in an unheated area.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your water heater.
Annual Maintenance (Recommended by a Qualified Professional):
- Inspect and clean the steatite heating element for limescale build-up.
- Check the condition of the ACI Hybrid anode and replace if necessary.
- Inspect the safety group (pressure relief valve) for proper operation and clear any blockages.
- Drain and flush the tank to remove sediment.
- Check all electrical connections for tightness and signs of wear.
User Maintenance:
- Regularly operate the safety group's manual discharge lever (once a month) to prevent blockages.
- Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners.
