Here's a comprehensive list of tasks a technician typically performs during geyser installation and setup:

1. Pre-Installation Check

• Site Assessment: Evaluate the location for geyser installation, ensuring there's enough space, proper ventilation, and an accessible power supply.
• Ensure Compatibility: Confirm that the geyser’s specifications (capacity, voltage, etc.) match the needs of the household and the available infrastructure.
• Confirm Safety Compliance: Ensure that the electrical connections, plumbing, and general setup comply with local safety standards and codes.

2. Unboxing and Preparing the Geyser

• Inspection of the Unit: Check the geyser for any visible damage, leaks, or defects from the manufacturer.
• Gather Tools and Materials: Collect necessary tools and fittings for installation, including a wrench, pipe connectors, electrical wiring tools, etc.

3. Water Supply Connection

• Shut Off Water Supply: Turn off the main water supply to prevent any leaks or water wastage during installation.
• Install Inlet and Outlet Pipes: Connect the cold water inlet and hot water outlet pipes to the geyser. Ensure the pipes are tightly sealed to avoid leaks.
• Check for Proper Alignment: Ensure that the pipes are properly aligned and fit securely without any strain.

4. Electrical Connection

• Turn Off Power Supply: Shut down the power supply to the area to ensure safety during electrical work.
• Wiring: Properly wire the geyser according to the manufacturer’s manual, including connection to a dedicated power circuit, and ensure the use of proper insulation and grounding.
• Install Circuit Breaker (if required): Install a circuit breaker or fuse to prevent overload.
• Testing Voltage: Ensure that the geyser receives the correct voltage as per its specification.

5. Mounting the Geyser

• Position the Geyser: Securely mount the geyser on the wall or in the designated space, ensuring it's level and stable.
• Attach the Geyser to Mounting Brackets (if applicable): Use brackets and screws to mount the geyser in place. Ensure it is firmly attached to prevent accidents.

6. Pressure Testing and Leak Check

• Check Water Pressure: Verify that the incoming water pressure is suitable for the geyser’s operation. Make adjustments if necessary.
• Leak Test: Turn on the water supply and check for any leaks at the connections. Tighten fittings as needed.

7. System Initialization and Testing

• Turn on Power Supply: Reconnect the power supply to the geyser and test if the unit is heating properly.
• Test Water Heating: Check if the geyser is heating the water efficiently and if the thermostat and temperature settings are functioning correctly.
• Check for Safety Features: Ensure that any safety features like pressure relief valves, temperature cut-offs, or anti-leak sensors are working correctly.

8. Final Inspection

• Inspect Entire Setup: Review the complete installation for compliance with safety standards, neatness, and correct wiring.
• Clean the Area: Remove any packaging materials, tools, or debris from the installation site.
• Provide Usage Instructions: Explain how to operate the geyser, set the temperature, and perform basic maintenance.
• Test the Geyser for Full Functionality: Ensure everything is working properly by running hot water for a few minutes to confirm the geyser’s performance.

9. Documentation

• Provide Warranty and User Manual: Hand over the warranty and the user manual to the customer.
• Record the Installation Details: Document the installation date, serial number of the geyser, and any special instructions or configurations made during the process.

10. Post-Installation Support

• Answer Customer Queries: Address any concerns or questions the customer may have about geyser usage, maintenance, or troubleshooting.
• Offer Maintenance Tips: Provide advice on how to maintain the geyser for optimal performance and longevity.

This checklist covers all the necessary steps for a proper geyser installation and ensures that the system operates safely and efficiently.
