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 refrig-  
erant 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.

non-fixed position or a wall-mounted position.  
To ensure that the air conditioner operates correctly, do  
not install the remote control unit in the following places:  
G In direct sunlight  
G Behind a curtain or other place where it is covered  
G More than 26' (8 m) away from the air conditioner  
G In the path of the air conditioner’s airstream  
G Where it may become extremely hot or cold  
G Where it may be subject to electrical or magnetic  
interference  
G Where there is an obstacle between the remote con-  
trol unit and the air conditioner (since a check signal  
is sent from the remote control unit every 5 minutes)
