3. Setup and Installation

Installation of this mini split system requires specialized tools and knowledge. It is highly recommended to hire a certified HVAC professional for proper installation to ensure optimal performance, safety, and warranty validity. Incorrect installation can lead to system malfunction, energy inefficiency, and void the product warranty.

Pre-Installation Considerations:

• Location: Choose a location for both indoor and outdoor units that allows for proper airflow, drainage, and accessibility for maintenance. Ensure the outdoor unit is placed on a stable, level surface.
• Electrical Requirements: This 12,000 BTU unit operates on 230V/60Hz. Confirm your electrical supply meets these requirements. A dedicated circuit with appropriate circuit breaker (Max. Fuse size 30A) is recommended.
• Room Size: This unit is designed for areas up to 550 sq.ft. Consider factors like insulation, window exposure, and heat sources when determining the appropriate BTU for your space.

Installation Steps (Professional Recommended):

1. Mounting Indoor Unit: Secure the mounting plate to the wall, ensuring it is level and at the correct height.
2. Drilling Wall Hole: Create a hole through the wall for the refrigerant lines, drain hose, and signal cable.
3. Connecting Piping: Connect the pre-charged copper line set to both the indoor and outdoor units. Ensure proper flaring and tightening to prevent leaks.
4. Electrical Wiring: Connect the electrical wiring between the indoor and outdoor units, and to the main power supply, following the wiring diagram in the full manual.
5. Vacuuming the Lines: A crucial step to remove air and moisture from the refrigerant lines. This requires a vacuum pump and manifold gauges.
6. Leak Test: Perform a leak test on all connections using a leak detector or soapy water.
7. Releasing Refrigerant: Once vacuumed and leak-tested, open the valves on the outdoor unit to release the pre-charged refrigerant into the system.
8. Drainage: Ensure the drain hose is properly sloped to allow for continuous condensate drainage.

Warning: This unit contains R454B refrigerant. Handling refrigerants requires proper certification and safety precautions. Do not attempt to open refrigerant lines without professional training and equipment.
