NOTICE

NTRODUCTION

This booklet contains the installation and operating instruc-

tions for your air handler. All warnings and precautions within

this booklet must be observed. Improper installation can re-

sult in unsatisfactory operation or dangerous conditions and

void the warranty. Read this booklet and any instructions

packaged with accessories prior to installation. Give this book-

let to the user and explain its provisions. The user should

retain this booklet for future reference.

NOTE: Upon start up in communicating mode the circuit board

will display a “1 Flash” error code on the diagnostic LED and

an “Ec” HTR TO LARGE error at the communicating display.

This is an indication that the dip switches on the control board

need to be configured in accordance with the Electric Heat-

ing Airflow Table on page 13 of this manual. Configuring the

dip switches and resetting power to the unit will clear the

error code.

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 modular blower instal-

lation and servicing to protect the integrated control module

from damage. By putting the modular blower, the control,

and the person at the same electrostatic potential, these steps

will help avoid exposing the integrated control module to elec-

trostatic discharge. This procedure is applicable to both in-

stalled 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

modular 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.

AVPTC AIR HANDLER INSTALLATION INSTRUCTIONS ® C US THIS PRODUCT CONTAINS ELECTRONIC COMPONENTS WHICH REQUIRE A DEFINITE GROUND. PROVISIONS ARE MADE FOR CONNECTION OF THE GROUND. A DEDICATED GROUND FROM THE MAIN POWER SUPPLY OR AN EARTH GROUND MUST BE PROVIDED. NOTICE IF A “1 FLASH” ERROR CODE OR AN “EC” HTR TOO LARGE ERROR IS ENCOUNTERED ON STARTUP, VERIFY THAT THE ELECTRIC HEATER DIP SWITCHES HAVE BEEN SET TO THE APPROPRIATE HEATER SIZE.

CHECKING PRODUCT RECEIVED Upon receiving the unit, inspect it for damage from shipment. Claims for damage, either shipping or concealed, should be filed immediately with the shipping company. Check the unit model number, specifications, electrical characteristics and accessories to determine if they are correct. In the event an incorrect unit is shipped, it must be returned to the supplier and must NOT be installed. The manufacturer assumes no responsibility for installation of incorrectly shipped units.

PRE-INSTALLATION INSTRUCTIONS Carefully read all instructions for the installation prior to installing product. Make sure each step or procedure is understood and any special considerations are taken into account before starting installation. Assemble all tools, hardware and supplies needed to complete the installation. Some items may need to be purchased locally. Make sure everything needed to install the product is on hand before starting.
PAGE 4
RETURN AIR FILTERS Each installation must include a return air filter. This filtering may be performed at the air handler or externally such as a return air filter grille. Air handlers mounted in the downflow orientation, including “B” series, require external filtering. A washable filter is available as an accessory. To ensure optimum performance frequent filter cleaning is advised. Refer to Air Filter Accessory table for the appropriate filter.

24 VOLT THERMOSTAT WIRING - NON-COMMUNICATING THERMOSTAT CONNECTIONS NOTE: Wire routing must not interfere with the circulator blower operation or routine maintenance. The air handler’s integrated control module provides terminals for “Y1” and “Y2” and “W1” and “W2” thermostat connections. This allows the air handler to support the systems shown in the table below. Refer to the following figures for typical connections to the integrated control module.

Be sure to follow this checklist step-bystep to ensure the sensing bulb is not damaged during installation. 1. Loosen the 13/16 nut 1 TURN ONLY. No pressure loss indicates possible leak. Unused Move to the ON position to enable dehumidification DEHUM OFF ON S7 To enable the dehumidification function, move the dehumidification dipswitch from OFF to ON. See following figure. 2.

FRONT VIEW Field experience has shown condensate drain traps with an open vertical Tee between the air handler and the condensate drain trap can improve condensate drainage in some applications, but may cause excessive air discharge out of the open Tee. Goodman® does not prohibit this type of drain but we also do not recommend it due to the resulting air leakage.

adjusted by the installer to match the installation requirements so as to provide the correct electric heating CFM and correct cooling CFM. Use the CFM LED (green), adjacent to the integrated control module electric heat connector to obtain an approximate airflow quantity. The green CFM LED blinks once for each 100 CFM of airflow.

• Profile D ramps up to 50% of the demand for 1/2 minute, then ramps to 82% of the full cooling demand airflow and operates there for approximately 7 1/2 minutes. The motor then steps up to the full demand airflow. Profile D has a 1/2 minute at 50% airflow OFF delay.

NOTE: For installations not indicated in the preceding Temperature Rise Tables, the following formula is to be used: 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.
PAGE 14
FAULT RECALL TROUBLESHOOTING The integrated control module is equipped with a momentary push-button switch that can be used to display the last six faults on the red diagnostic LED. The control must be in Standby Mode (no thermostat inputs) to use the feature. Depress the push-button for approximately two seconds and less than five seconds. The LED display will then display the six most recent faults beginning with the most recent fault and decrementing to the least recent fault.
PAGE 15
AIRFLOW CONSIDERATION In continuous fan mode, the CTK0*AA thermostat provides the airflow demand. The thermostat may be configured for a low, medium, or high continuous fan speed. The low, medium, and high fan speeds correspond to 25%, 50% and 75%, respectively, of the air handlers’ maximum airflow capability. During continuous fan operation, the thermostat sends a fan request along with the continuous fan demand to the air handler. The air handler, in turn, sends the demand to the ECM motor.
