CAUTION: Failure to follow these precautions could
result in damage to the unit being installed:
1. Make all electrical connections in accordance with
NEC ANSI/NFPA (latest edition) and local electrical
codes governing such wiring. In Canada, all electrical
connections must be in accordance with CSA standard
C22.1 Canadian Electrical Code Part 1 and applicable
local codes. Refer to unit wiring diagram.
2. Use only copper conductor for connections between
field-supplied electrical disconnect switch and unit.
DO NOT USE ALUMINUM WIRE.
3. Be sure that high-voltage power to unit is within
operating voltage range indicated on unit rating plate.
4. Insulate low-voltage wires for highest voltage con-
tained within conduit when low-voltage control wires
are run in same conduit as high-voltage wires.
5. Do not damage internal components when drilling
through any panel to mount electrical hardware, con-
duit, etc. On 3-phase units, ensure phases are balanced
within 2%. Consult local power company for correc-
tion of improper voltage and/or phase imbalance.
A. HIGH-VOLTAGE CONNECTIONS
The unit must have a separate electrical service with a field-
supplied, waterproof disconnect switch mounted at, or within sight
from, the unit. Refer to the unit rating plate for maximum
