Recommended Wire Length And Diameter; Wiring Instructions For Inter-Unit Connections - Sanyo KS1852 Installation Instructions Manual

3-7. Recommended Wire Length and Diameter

Regulations on wiring diameter differ from locality to
locality. For field wiring requirements, please refer to
your local electrical codes. Carefully observe these reg-
ulations when carrying out the installation.
NOTE
Refer to the wiring system diagram (Fig. 23)
Refer to your local codes or in the absence of local
codes with the National Electric Code: ANSI/NFPA70.
WARNING
Be sure to comply with local codes on running
the wire from the outdoor unit to the indoor unit
(size of wire and wiring method, etc.).
Each wire must be firmly connected.
No wire should be allowed to touch refrigerant
tubing, the compressor, or any moving part.
WARNING
To avoid the risk of electric shock, each air
conditioner unit must be grounded.
CAUTION
Be sure to connect the power supply line to the
outdoor unit as shown in the wiring diagram. The
indoor unit draws its power from the outdoor
unit.
