Electric Heat - Installation, Operation, and Maintenance
Revised: 04 August, 2015

Overview
The AG Series Auxiliary Electric Heat mounts internally on
TS, TE and TT upow (Figure 1b) or downow 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. Downow 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.

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 upow 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.

a transition bracket between the cabinet panel and
the electric heater. This bracket is packaged inside the
blower compartment for eld installation.
4. Position the electric heater as illustrated herein. Notice
that the discharge air opening is o centered in the
blower panel. The electric heater must be positioned so
that its control box is located vertically over the wide
side of this panel.
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

Wiring and Setup (all models)
1. Install power wiring and connect to power block or
circuit breakers. In 15 or 20kW models two power
circuits may be used to reduce wiring and breaker
costs as in Figure 8a. If a single circuit supply is
desired, install the optional single circuit accessory kit
(P/N 16B0002N02), as shown in Figure 8b, that can be
obtained from your distributor.
Optional for TAH: AG**C kits only. Blower power may
be supplied from T3 & T4 CB5 breaker. Refer to wiring
diagram 96B0143N01.
2.
Ensure unit airow setting is above minimum airow rating
for the electric heat model from Table 1.
3. Check heat staging for the application. Table 4 contained
later in this IOM shows the factory default staging and
the alternate eld selectable staging where applicable.
Staging changes are made by dip switch settings. See
gure 9. These are identied as either ER1, ER2, ER3 or
ER4 depending on the heater size.
4. Mark the appropriate box of the electric heat model
installed on the additional serial plate on the exterior of
the unit.
5. Turn on the power to the unit and the auxiliary
electric heat.
Auxiliary Electric Heat Start-up
Put thermostat in emergency heat mode (or jumper t-stat
input R to W and R to G) and setpoint to high setting. ‘Touch-
jumper' the test pins of the CXM or DXM into test mode to
reduce time delays. Unit will require 15-20 seconds before
engaging emergency heat mode stage 1 (W1) and then
another 15-20 seconds to engage stage 2 (W2) when in ‘Test
mode’. Verify proper electric heat operation.

The maximum recommended air velocity for a supply plenum is 900 fpm. When connecting a plenum to an external
supplemental heater, ensure that the air velocity in the plenum does not exceed 900 fpm. Noise and air distribution issues
may occur if supply plenum velocities exceed 900 fpm.
