2. All heater packages covered by this manual are factory wired for single supply circuit. The following heater packages are field convertible to a dual supply circuit if required or desired:

EHWA03-A15

EHWH30-A10

EHWH36-A10

EHWH36-A15

3. To convert the above heater packages to dual circuit configuration before installation, loosen four

(4) screws holding jumper bar in place. Remove jumper bar. Circuits 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.

INSTALLATION

1. Disconnect all power to unit before installation.

WARNING

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.

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.

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.
