WIRING MAIN POWER
1. On all installations, size unit power supply wiring
for the minimum circuit ampacity requirement for
the unit and heater package combination listed on
the unit serial plate.
For existing installations, addition or upgrading of a
heater package may require that larger supply wires
be run to the unit. Resize all power supply wires for
the minimum circuit ampacity rating listed on the
unit serial plate that is applicable for your
combination of unit and heater package.
IMPORTANT
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.
SHIPPING DAMAGE
Upon receipt of equipment, the carton should be
checked for external signs of shipping damage. If
damage is found, the receiving party must contact the
last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.
UNPACKING ELECTRIC HEAT PACKAGE
Remove the heat package from the shipping carton. The
heat package must consist of the following:
1. Basic heater.
2. Electric heat control base and wiring.
3. Installation instructions.
4. Wiring diagram (2), one to be applied to unit.
5. Adhesive label to remark serial plate to indicate new
model number. This is attached to the front of these
instructions.
2. All heater packages covered by this manual are
factory wired for a single supply circuit. The
following heater packages are field convertible to a
dual supply circuit if required or desired.
EHWA05-A15 EHWH04-A05
EHWA05-A20 EHWH04-A10
EHWH42-A05 EHWH04-A15
EHWH42-A10 EHWH04-A20
EHWH42-A15
3. To convert the above heater packages to dual circuit
configuration before installation, loosen 4 screws
holding jumper bar in place. Remove jumper bar.
Circuit A + B are now identified on the heater
package. See Figure 1.
Wire should be sized to the minimum circuit
ampacity as specified on the serial plates of units
that accept these heater packages for circuits A + B.
WARNING
Install properly sized power supply leads for
the unit/heater combination minimum circuit
ampacity as listed on the unit serial plate.
Hazard of fire. Failure to install properly sized
conductors could result in fire.

INSTALLATION OF HEATER PACKAGE
1. Disconnect all power to unit before installation.
INSTALLATION
2. Before installation, check unit serial plate to insure
that the heater package model that you intend to
install is listed as a heater package suitable for use
with the unit.
Under no circumstances shall a heater package be
installed in a unit if the model number of the heater
package does not appear on the unit serial plate.
3. Remove electric heater access panel and control
panel cover, both inner and outer. See Figure 2.
4. All heaters are installed with the thermal cutoffs
positioned to the top of the unit. Install heat strip(s)
through heater access opening. Position heat strip
support rod in heater support hole 1, 2 or 3 as
indicated in Table 1 and Figure 3. Secure in place
with 2 sheet metal screws in mounting holes as
indicated in Table 1 and Figure 3. On heater
packages with 2 heat strips, install 9KW or 10KW
heater first in position closest to the outlet air frame.
See Figures 4E and 4F.
5. Install heater control base into top of control panel
as shown in Figure 5. Secure with 4 sheet metal
screws provided.
6. Plug male 6 pin connector into mating connector
mounted in control panel. See Figure 5.
7. Connect red compressor supply lead to L1 of
terminal block. Connect black compressor supply
lead to L2 of terminal block. If 3 phase, connect
yellow supply lead to L3 of terminal block. See
Figure 5 and wiring diagram.
8. Route wires from heater control base up through
raceway in top right corner of control panel to the
heaters. See Figure 5.
9. Wire heater package per wiring diagram supplied
with this heater package. All wires are stamped with
wire numbers that correspond with terminal numbers
on the wiring diagram and stamped numbers on the
heat strip. Limit switch wires are terminated with
insulated quick connect terminals. See Figure 4.
10. Attach adhesive wiring diagram directly above unit
wiring diagram on inner control panel cover.
11. Recheck all wiring. Break out appropriate circuit
breaker tabs on inner control panel cover to allow
trip lever to protrude. Replace control panel and
heater access panels
12. Resupply power to the unit and check for proper
operation.
13. Remark serial plate with self-adhesive label attached
to the front of this manual. See Figure 6.
WARNING
Install only heater packages listed on unit
serial plate. Hazard of fire or electrical shock.
Failure to install listed heater package could
result in fire, injury or death.
WARNING
