Instruction manual

To change the speed of the indoor fan motor (IFM), remove fan
motor speed lead from the Time Delay Relay (TDR) and replace
with the lead for the desired blower motor speed. The motor speed
lead is attached to terminal TDR-3. For low and medium speeds,
black must be connected to the jumper wire. Insulate removed lead
end to avoid contact with chassis parts. To select high speed on
460-v GE motors, separate the black female quick connect (QC)
from the jumper lead male quick connect (QC) and connect the
black lead to the BR. Insulate the jumper to avoid contact with any
chassis parts.
