BLOWER CONVERSION FROM UPFLOW
TO COUNTERFLOW OR HORIZONTAL
RIGHT DISCHARGE

Following the directions on Figure 3 for counterow and

horizontal right discharge, the indoor blower must be

removed and turned over in its mounting conguration.

• Step 1 Remove both front service panels from the

GTB1-A.

• Step 2 Remove two screws securing blower at top
of GTB1-A (See Figure 3), and slide the
blower forward and out of the chassis.

• Step 3 Remove two screws from front ll plate on

bottom of GTB1-A, and slide both pieces of
metal forward and out of chassis.

• Step 4 Dip switch #4 on blower tap select control
must be turned “on”. (Refer to Wiring
Diagram 4117-100.)

• Step 5 While turning on tap #4 above, adjust the
other taps accordingly for the tonnage of unit
being applied. (Refer to Wiring Diagram
4117-100.)

• Step 6 Turn blower over and slide into rails of

bottom rear of the GTB1-A front ll plate

that was removed in Step 3 above.

• Step 7 Remove bottom rear ll plate from bottom

front ll plate (discard rear), and resecure
front ll plate into unit base and front of

blower.

• Step 8 Replace GTB1-A front service doors after
making line and control voltage wiring
connections.

BLOWER LINE POWER CONNECTION

Power connections for the GTB1-A can be made two
different ways.

The rst is in “stacked” congurations, the blower can

be plugged into an electrical connection from the bottom
of the compressor (GTC**S2 Model Unit). This will

work for either upow or counterow applications. All

electrical sizing has been sized to accommodate this.
The second is with “remote” blower (meaning separate

from the compressor section). Supplied in the GTB1-A
is an adaptor wire harness. On the right-hand side of the
GTB1-A chassis is a ½" electrical knockout. This harness
can be installed through this knockout with the supplied

strain relief into a standard electrical junction box (eld

supplied). Electrical load sizing is included on the serial
