1. Disconnect all power to unit before installation.
WARNING
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.
On heater packages with two (2) heat strips, install
9KW heater first in position closest to the outlet air
frame. See Figure 4E.
5. Install heater control base into top of control panel
as shown in Figure 4. Secure with four (4) sheet
metal screws provided.
6. Plug mail six (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 three phase,
connect yellow supply lead to L3 of terminal block.
See Figure 4 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.
Disconnect all power to unit before installing
heater package. Hazard of electrical shock.
Failure to disconnect power could result in injury
or death.
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 circumstance 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.
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.
9. Wire heater package per wiring diagram supplied
