3. Setup

3.1 Unpacking

Carefully remove the water heater from its packaging. Inspect the unit for any signs of damage during transit. Retain the packaging materials for future transport or if the unit needs to be returned. Ensure all included components are present: Water Heater, Wall clamp with fitting screws, Remote control, User manual, and Guarantee card.

3.2 Mounting

The VENUS Lyra Digital 015RD is designed for vertical wall mounting. Choose a suitable location that is structurally sound, close to water supply and drainage, and protected from freezing temperatures. Use the provided wall clamp and fitting screws to securely mount the water heater. Ensure there is adequate space around the unit for maintenance and ventilation.

• Mark the drilling points on the wall using the wall clamp as a template.
• Drill holes and insert appropriate wall plugs (if necessary, depending on wall material).
• Securely fasten the wall clamp to the wall.
• Carefully lift and hang the water heater onto the wall clamp, ensuring it is stable and level.

3.3 Plumbing Connections

Connect the water inlet and outlet pipes to the corresponding ports on the water heater. The inlet is typically marked with blue or 'C' (cold), and the outlet with red or 'H' (hot). Use appropriate plumbing fittings and sealants to ensure leak-free connections. Install a pressure relief valve (PRV) as per local codes, if not already integrated.

3.4 Electrical Connections

Ensure the main power supply is switched off before making any electrical connections. Connect the water heater to a dedicated, properly earthed electrical circuit with appropriate voltage and current ratings as specified on the product label. A qualified electrician should perform this step.

3.5 Initial Filling

Before switching on the power, open a hot water tap in your home to allow air to escape from the tank. Then, open the cold water inlet valve to fill the water heater. Wait until water flows steadily from the hot water tap, indicating the tank is full. Close the hot water tap. Check all plumbing connections for leaks.

4. Operating Instructions

4.1 Powering On/Off

Once the water heater is filled with water, switch on the main power supply. The digital display will illuminate. To turn the heating element on or off, use the power button on the unit or the remote control.

4.2 Temperature Setting

Use the temperature control buttons (usually '+' and '-') on the unit or remote control to set your desired water temperature. The digital display will show the current water temperature and the set temperature. The heating element will activate until the set temperature is reached, then automatically switch off.

• The color ring on the unit changes from blue to red when the water is completely heated and ready for use.

4.3 Smart Mode and Power Consumption Display

The Lyra Digital 015RD features a smart mode that helps optimize power consumption. Refer to the remote control instructions for activating and customizing smart mode settings. The digital display also shows the power units consumed, allowing you to monitor energy usage.

4.4 Remote Control Usage

The included remote control allows convenient operation from a distance. It can be used to:

• Turn the water heater on/off.
• Adjust the water temperature.
• Activate smart mode.
• Set timers for heating cycles (if available on your model).

Ensure the remote control has fresh batteries and is pointed towards the water heater's receiver for optimal functionality.

5. Maintenance

Regular maintenance ensures the efficiency and extends the lifespan of your water heater. Always disconnect the power supply before performing any maintenance.

5.1 Exterior Cleaning

Clean the exterior casing of the water heater with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.

5.2 Draining the Tank

If the water heater will be out of use for an extended period or if there is a risk of freezing, the tank should be drained. To drain:

• Switch off the power supply to the water heater.
• Close the cold water inlet valve.
• Open a hot water tap in your home to relieve 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.

5.3 Anode Rod Inspection and Replacement

The anode rod protects the tank from corrosion. It should be inspected annually and replaced if significantly corroded. This procedure typically requires professional assistance.

5.4 Descaling

In areas with hard water, mineral deposits (scale) can accumulate inside the tank and on the heating element, reducing efficiency. Descaling should be performed periodically by a qualified technician.
