Installing the FUJITSU 19.7 SEER Ducted Mini-Split Heat Pump System requires following specific guidelines to ensure safe and efficient operation. Here are the general steps for installation:
1. Read the instruction manual carefully: Before starting the installation process, thoroughly read the instruction manual provided with the product. Familiarize yourself with the safety precautions and installation requirements.
2. Follow local electrical codes: Ensure that the installation is performed in accordance with the requirements of the National Electrical Code (NEC) and Canadian Electrical Code (CEC) by authorized personnel only. Adhere to all local, state, and national electrical codes.
3. Select a suitable installation location: Choose a location for the outdoor unit that can withstand its weight and vibrations. Avoid areas with high salt content, heat sources, strong winds, or exposure to direct sunlight. Consider the proximity to neighbors and obtain their approval if necessary.
4. Install the outdoor unit: Securely install the outdoor unit on a solid base or raised stand. Use anchor bolts to secure it, ensuring it is level and stable. Leave sufficient space around the unit for proper airflow and maintenance access.
5. Install the piping: Cut the connection pipes to the necessary length using a pipe cutter. Flare the pipes using a flaring tool and connect them to the appropriate ports on the indoor and outdoor units. Use the specified torque to tighten the flare nuts.
6. Perform sealing and vacuum tests: After connecting the pipes, perform a sealing test using nitrogen gas to check for leaks. Evacuate the refrigerant system using a vacuum pump to remove any air and moisture. Check for pressure stability and perform a leak check.
7. Electrical wiring: Install conduit for electrical wiring and connect the inter-unit wire harness and power supply to the terminal. Use designated cables and ensure proper grounding. Follow the wiring instructions provided in the manual and adhere to electrical safety precautions.
8. Perform additional charging: If the piping length exceeds the specified maximum, additional refrigerant charging may be required. Follow the guidelines provided in the manual for the specific model and pipe length.
9. Perform gas leakage inspection: After completing the installation, check all joints for gas leakage using a gas leak detector. Ensure there are no leaks before proceeding.
10. Test and commission the system: Once the installation is complete, turn on the power and test the system's operation. Check for proper cooling and heating functions, airflow, and thermostat control. Provide the customer with instructions on correct operation using the operating manual.
It is important to note that these are general installation steps, and it is recommended to refer to the specific instructions provided in the FUJITSU 19.7 SEER Ducted Mini-Split Heat Pump System Instruction Manual for detailed and model-specific installation guidelines.
