*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.
