* Air delivery values are based on operaf_ng voltage of 230-v or 460-v, wet coil, without filter or electric heater. Deduct l#ter and elect#t: heater pressure drop (see Tables
5 and 6) to obtain sta'6c pressure available for dueling.
NOTES:
1. DO not operate the unit at a cOOlingairflow that is less than 350 cfrn for each 12.000 Btuh of rated cooling capacity¸ Evaporator coil frosting may occur at ain3ows below
this point.
2. Dashes indicate portions of table that are beyond the blower motor capacity or are not recommended.
3. Deduct 10 percent for 208-v.

3-SPEED
Black = high
Violet = jumper
Orange = medium
Red = low
To change the speed of the blower motor (BM), remove fan motor
speed lead from the blower relay {BR_ and replace with the lead
for the desired blower motor speed. The motor speed lead is
attached to terminal BM, 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 connecl the black lead
to the BR. Insulate the jumper to avoid contact with any chassis
parts.
