●Install the indoor unit more than 3.3' (1 m) away from any antenna or power lines or connecting wires used for tele- vision, radio, telephone, security system, or intercom.

Electrical noise from any of these sources may affect operation.

●install in a sturdy manner to avoid increased operating noise.

*If total tubing length becomes 150 to 200 ft. (Max.) or 150 to 230 ft. (Max.), charge additional refrigerant (R410A) by 0.22 oz./ft.

No additional charge of compressor oil is necessary. For more detailed charging information, refer to the Technical & Service Manual.

2-2. Embedding the Tubing and Wiring

●Before beginning embedding installation work, consult fully with agencies or offices related to the building’s foundation, construction, electricity, and water.

●Wait to make connections to the embedded portion. Each connection step is described later in this manual.

●Securely cover the end of the embedded tubing to prevent intrusion of dirt or moisture.

●If an embedded tube is to be left for a long time, fill the tube with nitrogen and seal both ends securely. If a tube is left open for an extended time, moisture in the air inside the tubing may condense into water droplets, and lead to water contamination of the refrig- erant circuit.

●In order to prevent insulation breakdown and ground faults, do not allow wiring ends to come in contact with rainwater, or be subjected to condensation or dew.

●Apply sufficient thermal insulation to the refrigerant tubing and drain pipes.
