Installation Instructions

  1. Unpacking
    Carefully unpack the unit and inspect the contents for damage. If any damage is found at the time of delivery, proper notification and claims should be made with the carrier.
    Check the rating plate to assure model number and voltage, plus any kits match with what you ordered. The manufacturer should be notified within 5 days of any discrepancy or parts shortage.

  2. Location
    The air handler should be centrally located and may be installed in a closet, alcove, utility room, basement, crawl space or attic. Minimum clearances must be met.
    The unit should be installed in a level position to ensure proper condensation drainage. Up to an additional 1/4” rise over the width or depth of the unit is allowed to create additional sloping towards the drain. Unit must be positioned between level and ¼” rise, sloping toward the drain connections. When the unit is installed in a closet or utility room, the room should be large enough, and have an opening to allow replacement of the unit. All servicing is done from the front and a clearance of 21″ is needed for service unless the closet door aligns with the front of the air handler.
    If you are installing the unit in an unconditioned space such as an attic or crawl space, you must ensure that the area provides sufficient air circulation to prevent moisture collection on the cabinet during high dew point conditions. A drain pan must be installed under the entire unit when it is installed in or above a finished ceiling or in an unconditioned space.

  3. Duct Work
    The duct work should be installed in accordance with the NFPA No. 90A “Installation of Air Conditioning and Ventilating systems” and No. 90B “Residential Type Warm Air Heating and Air Conditioning Installation.”
    The ductwork should be insulated in accordance with the applicable requirements for the particular installation as required by HUD, FHA, VA the applicable building code, local utility or other governing body.

  4. Condensate Drain
    The unit is supplied with primary and auxiliary condensate drains that have 3/4″ NPT connections. The primary drain must be trapped outside the unit and piped in accordance with applicable building codes.
    The figure shows the operation of a properly designed trap under normal operating conditions when the blower is running and the condensate is draining. Note the difference in height of the water column must at least equal the normal negative static pressure existing during operation between the cooling coil and blower. It is advisable to have the difference in water column height somewhat greater than the normal maximum operating static to allow for greater static caused by dirty filters or for the bounce of the water column on start up.

    • Proper operation of condensate trap under normal operating conditions.

    • “A” height of water column equals negative static pressure existing in system. “C” dimension should at least equal two times the maximum negative static pressure that can occur in system.
      Do not reduce the drain line size less than the connection size on the drain pan. Condensate should be piped to an open drain or to the outside. All drains must pitch downward away from the unit a minimum of 1/4″ per foot of line to ensure proper drainage

    • Important: If cleanout Tee is used, stand pipe must be sealed/capped.

    • Important: If a vent Tee is used, it must be downstream from the trap. Insulate the primary drain line to prevent sweating where dew point temperatures may be met. (Insulation is optional depending on climate and application needs.)

  5. Refrigerant Piping
    Refrigerant piping external to the unit shall be sized in accordance with the instructions of the manufacturer of the outdoor equipment.

  6. Metering Device
    All units are shipped and installed with an internally-checked, non-bleed TXV designed for air conditioning or heat pump operation. Some outdoor models may require a start assist kit. See outdoor unit for more information.

  7. Blower
    This unit is supplied with a variable speed motor with a direct drive blower wheel which can obtain various air flows. The unit is shipped with factory set cooling and heating air flows. Performance tables are available for additional airflow settings. Disconnect all power to the unit before making any adjustments to the airflow settings. Be sure to check the air flow and the temperature drop across the evaporator coil to ensure sufficient air flow.

Electric Code NFPA No. 70 and any local codes. Check rating plates on unit for rated volts, minimum circuit ampacity and maximum over current protection. Supply circuit power wiring must be 75 degree C (167 degree F) minimum copper conductors only. Copper supply wires shall be sized to the National Electric Code or local code requirements, whichever is more stringent.

The unit is shipped wired for 230/240 Volt AC 60 HZ 1 Phase Operation. If the unit is to be operated at 208 VAC 60HZ, follow the instructions on the indoor unit wiring diagram to change the low voltage transformer to 208 VAC operation (Ensure unit is properly grounded).

Class 2 low voltage control wiring should not be run in conduit with power wiring and must be separated from power wiring unless class 1 wire with proper voltage rating is used.
Low voltage control wiring should be 18 Awg, color coded (105 degree C minimum). For lengths longer than 100ft., 16 Awg wire should be used. Make certain that separation of control wiring and power wiring has been maintained.

Air Filter
To protect the coil, blower and other internal parts from excessive dirt and dust an air filter must be installed before air enters the evaporator coil. A remote filter must be installed. Consult the filter manufacturer for proper sizing and maximum velocity requirements.

Important: Air filters shall meet the test requirements in UL 900.

Operational and Checkout Procedures
To obtain proper performance, all units must be operated and charge adjustments made in accordance with procedures found in the Service Facts document of the outdoor unit. After installation has been completed, it is recommended that the entire system be checked against the checkout list located at the back of this document. See “Checkout Procedures,” p. 27.

Maintenance
The system air filter(s) should be inspected, cleaned or replaced at least monthly. Make certain that the access panels are replaced and secured properly before placing the unit back in operation. This product is designed for dependable service; however, periodic maintenance should be scheduled and conducted by trained professional service personnel. This service should be conducted at least annually and should include testing and inspection of electrical and refrigerant components, flushing of condensate drain, and repriming of condensate trap.

    The installing and servicing technician should have an understanding of the sequence of operation to be able to properly setup and diagnose functions of the air handler.
    See unit, electric heat, and field wiring diagrams for additional information

Continuous Fan

Important: If the indoor air exceeds 60% relative humidity or simply feels uncomfortably humid, it is recommended that the indoor fan only be used in the AUTO mode.

  1. When a fan request is received from the thermostat, the AFC sends a command to the serial communicating blower motor to run. Airflow can be adjusted through the thermostat.
  2. Humidity Control – When enabled at the thermostat, this feature will disable any blower off delays and disable continuous fan mode when the humidity is above the dehumidification setpoint. This will help prevent coil condensation from being evaporated back into the air stream.

Cooling Mode

  1. When a request for 1st stage cooling is received, the AFC sends a command to the serial communicating blower motor to run at 1st stage cooling airflow. (Delay profiles from the thermostat may change blower motor timing and actual airflow demand)
  2. When a request for 2nd stage cooling is received, the AFC sends a command to the serial communicating blower motor to run at 100 % cooling airflow.
  3. When a request for cooling is removed, the AFC will turn off the blower motor after any user selected fan-off delays have expired.
    Note: Delay profiles from the thermostat may change blower motor timing and actual airflow demand

Heat pump (compressor only)

  1. When a request for 1st stage heat is received, the AFC sends a command to the serial communicating blower motor to run at 1st stage heating airflow.
  2. Humidifier contacts close on demand from thermostat.
  3. When a request for 2nd stage mechanical heat is received, the AFC sends a command to the serial communicating blower motor to run at 100 % heating airflow.
  4. When a request for heat pump is removed, the AFC will turn off the blower motor after any user selected fan-off delays have expired.

Note: Delay profiles from the thermostat may change blower motor timing and actual airflow deman

Electric Heat

  1. When a request for electric heat is received, the AFC will energize the on board 24 volt relays per the amount of heat requested from the thermostat and the size of the heater installed.
  2. The AFC sends a command to the serial communicating blower motor to run proper airflow and close the blower interlock relay on the EHC.

Defrost

  1. The OD unit will initiate defrost and send a message to the AFC.
  2. Electric or hydronic heat will be energized to help temper the air.

Unit Test Mode
Unit Test Mode will exit if any demand is given to the unit.

To enter Unit Test Mode:

  1. Set System Switch on comfort control to Off.
  2. Scroll down to the Unit Test selection and push the “Enter” button

Sequence of Unit Test Mode (OD unit is not energized during the Unit Test Mode

  1. AFC energizes the blower at 50% and then continues to ramp until it reaches 100% cooling airflow.
  2. Humidifier contacts close when the blower starts.
  3. AFC energizes the W relays in 10 second intervals. The blower remains at 100% air flow.
  4. All relays de-energize and the blower shuts off five seconds after the last bank of heat is energized.
    Note: If an error occurs during the Unit Test Mode, the Fault LED will flash a code and continue the test.

•        † Factory Setting

•        Status LED will blink once per 100 CFM requested. In torque mode, actual airflow may be lower.

•        To prevent water blow-off, the max airflow demand allowable is 1000 CFM. If an outdoor

multiplier and cooling airflow setting should result in a demand higher than 1000, the AFC will default the demand back to 1000.

| •        Torque mode will reduce airflow when static is above approximately 0.3″ water column.

•        All heating modes default to Constant CFM.

•        In communicating mode, default CFM/Ton is 400.

•        Cooling airflow values are with wet coil, no filter

Note: Heater size needs to be set in Configuration Menu.

Coil Conversion Instructions

Downflow
Follow the conversion steps when installing the air handler in downflow configuration.

  1. Remove the front panels panel from the air handler.
    The coil and line set panel do not need to be separated.

  2. Remove the fasteners on both sides of the coil.

  3. Remove the two screws holding the center horizontal bracket and rotate out of place. Retain parts.

  4. Slide the coil assembly out. Remove and discard the horizontal drain pan.

  5. On both sides of the cabinet, remove the screws that hold the coil support brackets and retain for later use. Seal the holes to prevent air leakage.

  6. Rotate and lift the two coil support brackets to remove from front slots in cabinet.TEM8A0B24V21DC-Communicating-24-Volt-Control-Convertible-Air-Handlers-FIG-20

  7. Rotate the unit into the downflow orientation.

  8. Pre-drill two clearance holes in the cabinet at dimples located below the location the screws were removed for the coil support brackets. There is one hole per side. See location of holes.

  9. Replace the center horizontal bracket removed in Step 3. Use the screws retained from Step 3 to attach.

  10. Place coil support brackets into the lower set of slots and rotate into place. Push downward to lock into place.

  11. Secure each bracket with a screw that were previously removed.TEM8A0B24V21DC-Communicating-24-Volt-Control-Convertible-Air-Handlers-FIG-21

  12. Slide the coil assembly back into the air handler cabinet as shown.

  13. Remove the appropriate knock out for the condensate piping.

  14. Replace all panels.TEM8A0B24V21DC-Communicating-24-Volt-Control-Convertible-Air-Handlers-FIG-23

Horizontal Right
Follow the conversion steps when installing the air handler in horizontal right configuration.

  1. Remove the front panels from the air handler. The coil and line set panel do not need to be separated.

  2. Remove the fasteners on both sides of the coil. Retain the coil retaining brackets and screws.

  3. Remove the two screws holding the center horizontal bracket and rotate out of place. Retain parts.

  4. Make note of the horizontal drain pan orientation (up/down).

  5. Slide the coil assembly out.
    Important: For Horizontal Right applications, ON SOME MODELS the top panel assembly of the coil must be rotated for proper condensate management.

  6. On the right side of the top baffle, position a flathead tip underneath the top baffle flange and pivot the screwdriver downward to release the front tab as shown below.

  7. Repeat for right rear tab to release top baffle assembly from coil

  8. Rotate 180 degrees and snap all four corner tabs to lock in place.

  9. Remove left side water diverter brackets and screws and reinstall on the right side.
    Important: The coil slabs are different and the mount hole locations will vary. See the illustrations on the following pages that correspond to the unit tonnage to see the correct mounting position of the water diverter bracket.
    Important: The water diverter brackets are not symmetrical and will vary by tonnage Coil Conversion InstructionsTEM8A0B24V21DC-Communicating-24

  10. Relocate the horizontal drain pan from the left side of the coil to the right side.

  11. Remove the drain pan support bracket. Do not discard. Remove the two drain plugs from the front of the drain pan and insert them in the drains at the rear of the drain pan.
    Important: When reinstalling coil in Step 13, it is important that the coil corner locks in place under the tab in the side bracket to support the coil weight horizontally.

  12. Reinstall the drain pan support bracket. The bracket should be located between the two drain plugs as shown

  13. Slide the coil assembly back into the air handler cabinet.
    Important: Make sure that the coil corner locks in place under the tab in the side left bracket to support the coil weight in the horizontal right position.

  14. Replace the center horizontal bracket using screws removed earlier in Step 3.

  15. Replace the two coil retaining brackets removed in a previous step.

  16. Replace all panels.

Checkout Procedures

The final phase of the installation is the system Checkout Procedures. The following list represents the most common items covered in a Checkout Procedure. Confirm all requirements in this document have been met.

  • All wiring connections are tight and properly secured.
  • Voltage and running current are within limits.
