Blower Motor Speed-Tap Retrofit
Note: For GEH/V ½-5 ton units only.
Motors installed in the unit include 4-speed and 3-speed
configurations. All voltages include a 4-speed
configuration, with the exception of 380V, 415V, 460V
which contain a 3-speed arrangement and 575V which
contains a 2-speed arrangement. To modify the rpm of the
motor, the following steps must be followed.
1. Remove service access panel at the unit front.

WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow codes could result in death or serious injury.
