Heat Kit Selection; Troubleshooting - Goodman AVPTC42D14 series Installation & Operating Instructions Manual

If an electric heater kit has not been installed, set dip switches 9, 10, and 11 to any valid heater kit setting (see ariflow
table for valid settings). This will prevent an Ec Error code from being displayed.
NOTE: For installations not indicated in the preceding Temperature Rise Tables, the following formula is to be used:
Where: TR = Temperature Rise
kW = Heater Kit Actual kW
3412 = Btu per kW
Voltage Correction
1.08
CFM
NOTE: The Temperature Rise Tables can also be used to determine the air handler airflow delivery. When using these
tables for this purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions.
Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature
minus the room air temperature.
Use HKR specification sheets to determine the HKR available for a given air handler.

19.1 Electrostatic Discharge (ESD) Precautions
NOTE: Discharge body's static electricity before touching unit. An electrostatic discharge can adversely affect electrical
components.
Use the following precautions during air handler installation and servicing to protect the integrated control module from
damage. By putting the air handler, the control, and the person at the same electrostatic potential, these steps will help
avoid exposing the integrated control module to electrostatic discharge. This procedure is applicable to both installed and
uninstalled (ungrounded) blowers.
1. Disconnect all power to the blower. Do not touch the integrated control module or any wire connected to the control
prior to discharging your body's electrostatic charge to ground.
2. Firmly touch a clean, unpainted, metal surface of the air handler blower near the control. Any tools held in a person's
hand during grounding will be discharged.
3. Service integrated control module or connecting wiring following the discharge process in step 2. Use caution not to
recharge your body with static electricity; (i.e., do not move or shuffle your feet, do not touch ungrounded objects, etc.).
If you come in contact with an ungrounded object, repeat step 2 before touching control or wires.
4. Discharge your body to ground before removing a new control from its container. Follow steps 1 through 3 if installing
the control on a blower. Return any old or new controls to their containers before touching any ungrounded object.

Refer to the Troubleshooting Chart at the end of this manual for
assistance in determining the source of unit operational prob-
lems. The 7 segment LED display will provide any active fault
codes. An arrow printed next to the display indicates proper
orientation (arrow points to top of display). See Figure 31.
