3. Installation

Installation should only be performed by a qualified professional. Ensure all local plumbing and electrical codes are strictly followed.

3.1 Unpacking

1. Carefully remove the water heater from its packaging.
2. Inspect the unit for any signs of damage. Do not install a damaged unit.
3. Retain packaging materials for potential future transport or return.

3.2 Mounting

• Select a suitable location that can support the weight of the water heater when full.
• Ensure adequate clearance around the unit for maintenance and ventilation.
• Mount the water heater securely to a wall using appropriate fasteners and brackets (not supplied).

3.3 Water Connection

1. Connect the cold water supply to the inlet pipe (usually marked blue or with a 'C').
2. Connect the hot water outlet to your household hot water system (usually marked red or with an 'H').
3. Install a temperature and pressure relief (T&P) valve according to local codes.
4. Open the cold water supply valve and allow the tank to fill completely. Open a hot water faucet in your home to purge air from the system until water flows steadily.
5. Check all connections for leaks.

3.4 Electrical Connection

1. Ensure the main power supply is OFF at the circuit breaker.
2. Connect the water heater to a dedicated electrical circuit as specified in the technical specifications.
3. Ensure proper grounding.
4. Close the electrical access panel securely.

4. Operating Instructions

4.1 Initial Start-up

1. Ensure the water heater tank is completely filled with water (refer to Section 3.3).
2. Turn on the electrical power supply to the water heater at the circuit breaker.
3. The heating process will begin. The time required to heat the water will vary depending on the tank size and initial water temperature.

4.2 Temperature Adjustment

• Locate the temperature control knob at the bottom of the unit.
• Rotate the knob to adjust the desired water temperature. Settings typically range from 'Low' to 'High'.
• For safety and energy efficiency, it is recommended to set the temperature between 49°C (120°F) and 60°C (140°F). Higher temperatures increase the risk of scalding.
• The temperature gauge on the top of the unit will indicate the current water temperature.

5. Maintenance

Regular maintenance extends the life of your water heater and ensures efficient operation. Always disconnect power before performing any maintenance.

5.1 Draining the Tank

Draining the tank annually helps remove sediment buildup.

1. Turn off the power supply to the water heater.
2. Close the cold water inlet valve.
3. Open a hot water faucet in your home to relieve pressure.
4. Connect a hose to the drain valve at the bottom of the water heater and direct it to a suitable drain.
5. Open the drain valve and allow the tank to empty.
6. Once drained, close the drain valve, remove the hose, and refill the tank as per Section 3.3.

5.2 Anode Rod Inspection/Replacement

The anode rod protects the tank from corrosion and should be inspected every 1-2 years and replaced if significantly depleted. This procedure should be performed by a qualified technician.

5.3 T&P Valve Test

Test the Temperature and Pressure Relief (T&P) valve at least once a year to ensure it is operating correctly. Follow the manufacturer's instructions for the T&P valve. Exercise caution as hot water may be discharged.
