6 Installation Details

6.1 Electrical

All electrical wiring must be done according to
local codes. Additionally installations in the
USA, must conform to the current National
Electric Code (NEC) and Installations in
Canada must conform to current Canadian
Electric Code (CEC).
Nameplate data indicates the operating voltage,
phase, ampacity,
protection, and minimum voltage.
The contractor is to provide an individual
branch circuit for over current protection for the
unit as required by code. Some codes may
require a disconnect between the indoor and
outdoor unit. Run power supply wiring through
a weatherproof disconnect box and conduit to
the unit connection. Disconnects are required
to be within sight and easy reach of the unit
(usually within 3 feet).
Circuit breakers and disconnect switches
should be properly sized based on the required
codes and the unit's nameplate requirements.
Check the unit wiring diagram for the number of
conductors required. Ensure that the proper
AWG (gauge) and type of wired is used to
comply with code and the unit's nameplate.
Route neatly and protect from sharp edges and
damage. Inadequate wiring and/or improper
electrical supply will likely result in failure of the
compressor and other electrical components
and voids the warranty.
