POWER COnnECtiOnS
Single Point Power
Single Point Power when ordered provides the installer
with a main disconnect switch. The line side of this
switch (top) is where the installer is to land his main
power wires. Devices included in the Single Point
Power option are Supply Fan, Return Fan, Exhaust
Fan, Energy Recovery Wheel, Gas Heat, Electric
Heat and Ultra-violet Lights. Special Quoted devices
may be purchased with the air handler that are NOT
included in the Single Point Power option. These items
will require separate, additional power wiring by the
installer. When Single Point Power is NOT purchased
the installer is responsible for wiring to each electrical
component.
Motors for Supply Fan, Return Fan, Exhaust
Fan
A motor connection diagram may be found on the
inside of the motor terminal box or on a tag attached
to the motor. Be sure to make a flexible conduit
connection at the motor to permit fan belt adjustment
and movement of spring isolated fan assembly.
Refer
to Motor Data Nameplate for all motor specifications
(see Fig. 2-54).
