Wiring shown with dashed lines is to
be furnished and installed by the
customer. All customer- supplied
wiring must be copper only and
must conform to NEC and local
electrical codes. Codes may require
line of sight between disconnect
switch and unit.
Note: When electric heater
accessory is used single
point power entry or dual
point power entry is field
optional. Single point power
entry option is through
electric heater only.
