CAUTION
To prevent severe damage to the bottom of the unit, do not
fork lift unit after wood struts have been removed.
Bring condenser end of unit into alignment with the curb
first. Lower unit carefully onto roof mounting curb. When a
rectangular cantilever curb is used, care should be taken to
center the unit. Check for proper alignment and orientation
of supply and return openings with duct.
Rigging Removal
CAUTION
To prevent damage to the unit, do not allow crane hooks
and spreader bars to rest on the roof of the unit.
Remove spreader bars, lifting cables and other rigging
equipment.
ELECTRICAL WIRING
WARNING
HIGH VOLTAGE!
Disconnect all power before servicing or
installing this unit. Multiple power sources
may be present. Failure to do so may cause
property damage, personal injury or death.
WARNING
HIGH VOLTAGE!
To avoid personal injury or death due to
electrical shock, do not tamper with factory
wiring. The internal power and control wiring
of these units are factory-installed and have
been thoroughly tested prior to shipment.
Contact your local representative if assis-
tance is required.
CAUTION
Conduit and fittings must be weather-tight to prevent water
entry into the building.
For unit protection, use a fuse or HACR circuit breaker that
is in excess of the circuit ampacity, but less than or equal
to the maximum overcurrent protection device. DO NOT
EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE
SHOWN ON UNIT DATA PLATE.
All line voltage connections must be made through
weatherproof fittings. All exterior power supply and ground
wiring must be in approved weatherproof conduit.
The main power supply wiring to the unit and low voltage
wiring to accessory controls must be done in accordance
with these instructions, the latest edition of the National
Electrical Code (ANSI/NFPA 70), and all local codes and
ordinances.
The unit is factory wired for the voltage shown on the unit’s
data plate. Refer to model nomenclature in Appendix B for
voltage requirement for your unit.
NOTE: If supply voltage is 208V, lead on primary
of transformer(s) must be moved from the 230V
to the 208V tap. Refer to wiring diagram on unit
for details.
Main power wiring should be sized for the minimum
circuit ampacity shown on the unit’s database. Size wires
in accordance with the ampacity tables in Article 310 of
the National Electrical Code . If long wires are required,
it may be necessary to increase the wire size to prevent
excessive voltage drop. Wires should be sized for a
maximum of 3% voltage drop.
CAUTION
To avoid risk of property damage, personal injury or fire,
use only copper conductors.
CAUTION
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
NOTE: A weather-tight disconnect switch,
properly sized for the unit total load, must be
field or factory installed. An external field
supplied disconnect may be mounted on the
exterior panel. Switch shall be provided to
ensure all-pole disconnection from the supply
mains.
Ensure the data plate is not covered by the field-supplied
disconnect switch.
• Some disconnect switches are not fused. Protect the
power leads at the point of distribution in accordance
with the unit data plate.
• The unit must be electrically grounded in accordance
with local codes or, in the absence of local codes,
with the latest edition of the National Electrical Code
ANSI/NFPA 70, and/or the Canadian Electrical Code,
CSA C22.1, Part 1. A ground lug is provided for this
purpose. Do not use the ground lug for connecting a
neutral conductor.
