Failure of unit due to operation on improper
line voltage or with excessive phase unbalance
constitutes product abuse and will void your
warranty and may cause severe damage to the
unit electrical components.
Areas Without Convenience Outlet
It is recommended that an independent 115V power source
be brought to the vicinity of the roof top unit for portable
lights and tools used by the service mechanic.
NOTE: Refer to local codes for requirements.
These outlets can also be factory installed.
WARNING
Units installed on Roof Tops
Main power and low voltage wiring may enter the unit
through the condenser end of unit or through the roof curb.
Install conduit connectors at the desired entrance locations.
External connectors must be weatherproof. All holes in the
unit base must be sealed (including those around conduit
nuts) to prevent water leakage into building. All required
conduit and fittings are to be field supplied.
Supply voltage to roof top unit must not vary by more than
10% of the value indicated on the unit data plate. Phase
voltage unbalance must not exceed 2%. Contact your
local power company for correction of improper voltage or
phase unbalance.
