2-2. Embedding the Tubing and Wiring

G Before beginning embedding installation work,
consult fully with agencies or offices related to the
building's foundation, construction, electricity, and
water.
G
Wait to make connections to the embedded portion.
Each connection step is described later in this
manual.
G
Securely cover the end of the embedded tubing to
prevent intrusion of dirt or moisture.
G
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
refrigerant circuit.
G
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.
G Apply sufficient thermal insulation to the refrigerant
tubing and drain pipes.
