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. With
condenser end of the unit resting on curb member and using curb
as a fulcrum, lower opposite end of the unit until entire unit is
seated on the 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 PROPERTY DAMAGE, 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 THROUGHLY TESTED PRIOR TO SHIPMENT.
CONTACT YOUR LOCAL REPRESENTATIVE IF
ASSISTANCE IS REQUIRED.
CAUTION
To prevent damage to the wiring, protect wiring from sharp
edges. Follow national electrical code and all local codes
and ordinances. Do not route wires through removable
access panels.
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 ex -
cess 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 in -
structions, the latest edition of the National Electrical Code (ANSI/
NFPA 70), and all local codes and ordinances.
The main power supply shall be three-phase, three wire. The unit
is factory wired for the voltage shown on the unit’s data plate.
NOTE: If supply voltage is 208V, all leads on primary of trans -
former(s) must be moved from the 230V to the 208V tap.
Main power wiring should be sized for the minimum circuit ampac
-
ity shown on the unit’s data plate. 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.
