Manufacturer instructions

The Panasonic Etherea CS-Z35VKEW must be installed by a qualified professional in strict accordance with local electrical, building, and plumbing codes. As the unit utilizes R32 refrigerant, technicians must adhere to specific safety protocols regarding flammability and pressure. Installation involves mounting the indoor unit securely to a wall using the provided plate, ensuring proper clearance for airflow. Refrigerant piping must be connected using flared joints, vacuum-purged to remove moisture, and leak-tested before opening the service valves. Electrical connections require a dedicated circuit and proper grounding. Upon completion, perform a test run to verify cooling/heating operation and check for condensate drainage. Users should refer to the specific installation manual provided with the unit for precise torque settings and wiring diagrams, as improper installation may cause water leakage or system failure.

Fixed units must be installed by a qualified F-gas engineer. Find an installer — we'll match you with a local HVAC professional.
