Overview
Overview
The AG Series Auxiliary Electric Heat mounts internally on
TS, TE and TT upow (Figure 1b) or downow units and all
TAH units. It mounts directly to the blower outlet of TS, TE
and TT horizontal units (Figure 8) and on all TZ units. Note
the model compatibility Table 1. Horizontal units are rated
for zero clearance at the unit and 1" clearance for rst three
feet of duct, vertical units rated for zero clearance for both
unit and duct. Downow units can not be located directly
over a discharge register. The discharge plenum must be
constructed from non combustible material. The AG electric
heat contains a four stage relay control board which activates
the elements directly via an internally wired low voltage
harness. Low voltage signals (W1 and W2) are staged from
the CXM or DXM control of the unit.

Installation - Internal
1. Disconnect power to the unit.
2. Remove blower access panel(s) from the unit and
control box cover from the electric heater.
3. Remove blower mounting bolts and drop blower
assembly as shown in gure 2. Removal of electrical
wiring should not be necessary.
4. Position the electric heater as illustrated in gure 3 with
its control box facing the front access panel of the unit.
Attach heater to unit using the support pins on the back
and bolts on the front.
The electric heater air inlet dimensions should match the
unit blower outlet, installer should stop and refer to the
unit/heater compatibility chart later in this instruction or
consult factory if they do not match.
5. Re-install blower assembly on to electric heater using
pins and bolts as before. Check blower electrical wiring
for proper connection and remedy any pinched wire(s) or
contact with sharp edges.
6. Route the low voltage control harness through one of the
‘pie’ bushings in the heater control box and plug on to
the P2 connector. See gure 6.
7. Install power conduit through the unit cabinet as shown
in gure 7 and attach directly to the electric heater
control box. See gures 9a-c.
8. Replace all covers and panels, heater installation is
complete. Proceed to wiring and setup.

Electric Heat - Installation, Operation, and Maintenance
Revised: 04 August, 2015
Vertical Installation - External
1. Disconnect power to the unit.
2. Remove blower access panel(s) from the unit and control
box and element covers from the electric heater.
3. Locate remove and discard blower discharge anges
from the unit but save the screws. Flanges will be
packaged loose inside the blower compartment of
vertical upow units. TZ036 and 042 units require a
transition bracket between the cabinet top and the
electric heater. This bracket is packaged inside the
blower compartment for eld installation.
4. Position the electric heater as illustrated herein. Heater
control box should be facing the front access panel of
vertical units.
The electric heater air inlet dimensions should match
the unit air outlet, installer should stop and refer to the
unit/heater compatibility chart later in this instruction or
consult factory if they do not match.

5. Use the saved blower ange screws to attach the heater
by its anges to the unit panel except do not fasten
ange on control box side.
6. Use aluminum tape (not provided) to seal all four heater
anges to the blower panel.
7. Locate and route the low voltage control harness through
the top panel knockout(s). Seal the penetration ‘air tight’.
This harness is factory installed on all TZ units (wire-tied
to the fan housing).
8. Route the control harness through one of the ‘pie’
bushings in the heater control box and plug on to the P2
connector. See gure 5.
9. Install power conduit and attach directly to the electric
heater control box. See gures 5a-c.
10. Replace all covers and panels, heater installation is
complete. Proceed to wiring and setup.
