WIRING MAIN POWER 1. On all installations, size unit power supply wiring

for the minimum circuit ampacity requirement forthe unit and heater package combination listed onthe unit serial plate.

For existing installations, addition or upgrading of aheater package may require that larger supply wiresbe run to the unit. Resize all power supply wires forthe minimum circuit ampacity rating listed on theunit serial plate that is applicable for yourcombination of unit and heater package.

2. All heater packages covered by this manual arefactory wired for a single supply circuit. Thefollowing heater packages are field convertible to adual supply circuit if required or desired.

EHWA05-AXK EHWA03-AXKEHWH30-AXK EHWH36-AXKEHWH04-AXK EHWH05-AXK

3. To convert the above heater packages to dual circuitconfiguration before installation, loosen 4 screwsholding jumper bar in place. Remove jumper bar.Circuit A + B are now identified on the heaterpackage. See Figure 1.

Wire should be sized to the minimum circuitampacity as specified on the serial plates of unitsthat accept these heater packages for circuits A + B.

5. Install heater control base into top of control panelas shown in Figure 5. Secure with 4 sheet metalscrews provided.

6. Plug male 6 pin connector into mating connectormounted in control panel. See Figure 5.

7. Connect red compressor supply lead to L1 ofterminal block. Connect black compressor supplylead to L2 of terminal block. See Figure 5 or 5A andwiring diagram.

8. Route wires from heater control base up throughraceway or grommet in top right corner of controlpanel to the heaters. See Figure 5 or 5A.

9. Wire heater package per wiring diagram suppliedwith this heater package. All wires are stamped withwire numbers that correspond with terminalnumbers on the wiring diagram and stampednumbers on the heat strip. Limit switch wires areterminated with insulated quick connect terminals.See Figure 4.

10. Attach adhesive wiring diagram directly above unitwiring diagram on inner control panel cover.

11. Recheck all wiring. Break out appropriate circuitbreaker tabs on inner control panel cover to allowtrip lever to protrude. Replace control panel andheater access panels

12. Resupply power to the unit and check for properoperation.

13. Remark serial plate with self-adhesive label attachedto the front of this manual. See Figure 6.

3. Remove electric heater access panel and controlpanel cover, both inner and outer. See Figure 2 or2A.

4. All heaters are installed with the line break limitspositioned to the top of the unit. Install heat strip(s)through heater access opening. Position heat stripsupport rod in heater support hole 1, 2, or 3 asindicated in Table 1 and Figure 3. Secure in placewith 2 sheet metal screws in mounting holes asindicated in Table 1 and Figure 3.

INSTALLATION OF HEATER PACKAGE 1. Disconnect all power to unit before installation.

WARNINGDisconnect all power to unit before installingheater package. Hazard of electrical shock.Failure to disconnect power could result ininjury or death.

WARNINGInstall only heater packages listed on unitserial plate. Hazard of fire or electrical shock.Failure to install listed heater package couldresult in fire, injury or death.
