Step 7 — Make Electrical Connections —
Refer to
the unit rating plate for supply voltage, motor and heater am-
perage, and required circuit ampacities. (See Tables 2 - 4.) The
unit wiring diagram shows all factory and field wiring. Most of
the unit motors are dual voltage that are factory wired for a
specified voltage. The motors should be checked to ensure that
they are wired for the correct voltage and rotation.
Units equipped with factory-installed motor controls and
disconnect will comply with NEC requirements for disconnect,
motor controller and motor overload protection. Separate dis-
connect and motor starter are not required to comply with NEC
requirements.
All field wiring should be done in accordance with all appli-
cable local and national codes. Any factory wiring modifica-
tions without factory authorization will void all factory warran-
ties and nullify any agency listings.
The manufacturer assumes no responsibility for any dam-
age and/or injuries resulting from improperly installed or wired
components.
Install fan switches, thermostats and other accessories in
accordance with accessory manufacturer’s instructions and ap-
plicable wiring diagram.

NOTES:
1. Stages available:
a. Single phase: 1 to 12 kW, 1 stage only
3 to 12 kW, 1 stage or 2 stage
b. Three phase: 1 to 39.9 kW, 1 stage only
4 to 39.9 kW, 1 or 2 stage
12 to 39.9 kW, 1, 2 or 3 stage
2. Electric Heating Capacities (Btuh) = Heater kW x 3413
3. Electric Heater Amperage for Single-phase Power = (Heater
kW x 1000)/Applied Voltage
Electric Heater Amp. for 3-phase Power = (Heater kW x 1000)/
(Applied Voltage x 1.73).

Table 4 — MOTOR PERFORMANCE DATA (FULL
LOAD AMPS)
NOTES:
1. Motor full load amps refer to National Electric Code (NEC)
amps; actual motor nameplate amps may vary.
2. NEC data extrapolated for 277 v.
3. Motors are open drip proof, ball bearing, single speed, 1750
rpm rated at continuous duty, 104 F ambient with reversible
rotation.
4. 5HP motors available only on size 40 units.
SERVICE SWITCHES: — The service switch is an On/Off
switch on incoming power supply to unit. Proper amperage
load must be determined before switch can be selected. The
range of the fused or non-fused service switch is 0 to 40
amps.
Amp Load =
[Motor amps + Heater amps (if required)] x 1.20.
