To properly install the GREE MULTIU18HP230V1DO Split Type Wall-Mounted Air Conditioner, follow these steps:

1. Location: Secure the unit to a flat, solid floor using bolts. If mounting on a wall or roof, ensure the support is firmly secured to prevent movement during intense vibrations or strong winds. Do not install the outdoor unit in pits or air vents.

2. Installing the pipes: Use suitable connecting pipes and equipment for the refrigerant R410A. The maximum connection pipe length varies depending on the model. Wrap all the refrigerant pipes and joints and tighten the connections using two wrenches working in opposite directions.

3. Bleeding: After connecting the indoor and outdoor units, bleed the air and humidity from the refrigerant circuit using a vacuum pump. Follow the steps outlined in the manual, which include unscrewing and removing the caps from the valves, connecting the vacuum pump hose, operating the vacuum pump, checking for leaks, and replacing and tightening the caps.

4. Electrical Connections: Ensure all power wiring complies with local electric codes. Connect the power connection wire to the appropriate terminal and secure the connection. Provide a circuit breaker with suitable capacity as specified in the manual. An all-pole disconnect switch should be connected to the power supply wiring.

5. Maintenance: Use suitable instruments for the refrigerant R410A and avoid using mineral oils to clean the unit. Regularly check for gas leakage, ensure proper thermal insulation, and maintain sufficient drainage. Follow the maintenance guidelines provided in the manual.

It is important to note that installation must be done by trained and licensed service personnel. Contact a licensed HVAC contractor for installation to avoid any issues that may void the warranty.
