Page 4: Installation Checklist
INSTALLATION CHECKLIST Please Check or fill out as Completed PIPING CONNECTIONS Ensure both vapor and liquid lines are fully insulated separately with at least ½” wall insulation. Ensure the liquid line filter drier is installed near the air handler, and insulated as well. If a vertical riser of 10’ or more is present on the line set, the line set must be properly trapped to prevent oil slugging to the compressors; good practice in any riser. When making brazed connections, trickle nitrogen through the system (e.g. 2 PSI) to maintain clean braze joints and eliminate carbonization inside the piping during the braze process. The Acadia system comes pre‐charged with 50 PSI of dry nitrogen. This can be used for nitrogen trickling by cracking the service valves slightly. AIR HANDLER Install indoor air handler, ensuring proper duct sealing, insulation & distribution. Ensure all registers, supply and return, are open and unblocked. Ensure a duct flex connector is used to eliminate vibration transmission to the home. Ensure a proper air filter is installed on the return side of the air handler. Ensure condensate drain is installed properly, and trapped. Run 10‐conductor (minimum), 18 AWG control wiring from air handler to the thermostat, and from air handler to outside condenser unit. Connect control wiring following color codes provided in the install manual, Appendix B. Disconnect the low‐voltage leads from the transformer provided in the air handler from the air handler control board 24 VAC and Common terminals. Line‐voltage leads to the transformer must remain connected to power the ECM blower motor. Connect 24VAC and 24C provided from outdoor unit to the ¼” terminals labeled COM and 24VAC on the indoor AHU control board (seen in Appendix A, FIG1). Ensure the electrical service to the air handler is adequate for both the air handler and electric heat kit, if one is installed, per NEC and/or local codes. Ensure appropriate electrical disconnect size is installed, per NEC and/or local codes. Ensure the HP/AC jumper on the air handler control board is set to HP (Heat Pump). If an electric heat kit is installed, ensure the HEAT/NO HEAT Jumper on the air handler control board is set to the HEAT side. Leaving this jumper on NO HEAT disables all auxiliary heat relays. Set airflow jumpers in air handler in accordance with Appendix A. THERMOSTAT Install thermostat in a location where it will not be directly exposed to conditioned air or drafts from doors and/or windows. Insulate between the base plate of the thermostat and the wall to prevent drafts from affecting the thermostat. Ensure that a jumper between W2 and W/E is not installed on the thermostat. Ensure that a jumper between RC and RH is installed on the thermostat. Configure the thermostat’s installer configuration menu as indicated in the installation manual, Appendix A: ‘Thermostat Settings’. ... - Page 5 INSTALLATION CHECKLIST OUTSIDE CONDENSER UNIT Ensure proper clearances are observed around the unit in accordance with Appendix D in the installation manual, making sure to provide appropriate space for accessibility to the compressor compartment’s access panel (30 inches minimum). Ensure condenser is placed on appropriate snow stands (not blocks, sleepers, etc.) per climate region with a minimum of 12” clearance to ground. Ensure outdoor unit is level. Ensure the outdoor coil’s drainage holes are not obstructed, providing full drainage runoff during the defrost cycles. Check factory tubing to ensure tubes are not rubbing against each other or any sheet metal. Pay close attention to distributor tubes on both indoor and outdoor coils. Ensure transformer is wired appropriately for applied line voltage. For correct wiring, see Line Voltage diagram in Appendix B. Unit is factory wired for 230VAC. Ensure the 10 conductor, 18 AWG control harness has been correctly wired between the thermostat, indoor air handler, and outdoor unit, following color codes and schematics provided in Appendix B. Ensure the electrical disconnect is properly sized for the outdoor unit, per NEC and/or local codes. Ensure all electrical connections are weather tight. Ensure all cabinet and electrical fasteners are secure. Shipping vibration can loosen connections. Ensure control wiring is not chaffing/grommet is installed. Charging the System Ensure both vapor and liquid service valves are open and back‐seated. Ensure system has been properly evacuated to at least 500 microns. A triple evacuation is the preferred method for a clean installation. Ensure the R‐410A INITIAL CHARGE is weighed in as a liquid through the 3/8” service valve port inside the compressor compartment. FINAL CHARGE (if required) is to be weighed in through the ¼” charging port on the outside of the unit while the system is operating (this port is always reading the low pressure side of the system). The vapor service valve port is high‐pressure gas during heating operation and low‐pressure gas during cooling operation. Charging operations should always be performed in heating mode. If the unit must be charged in cooling mode, a return trip may be required to check the charge during heating season. Total charge amount is dependent on the total length of the liquid line. See the Line Set Charging Chart in Appendix C. ...
- Page 6 INSTALLATION CHECKLIST System Startup and Checkout Ensure the access cover to the air handler is in place to establish proper air flow across the indoor A‐coil while the system is operating. After applying power, ensure electrical voltage ratings are within specifications. If the voltage is outside of specification, contact your local utility company. Verify control board heartbeat is active, and no error conditions are present. Obtain an accurate measurement of the outdoor temperature at the outdoor unit. Measure liquid line temperature by attaching and insulating an accurate thermistor type or electronic thermometer to the 3/8” liquid line near the outdoor coil. Place the system into a Stage 2 heating call (24V on Y2 terminal at outdoor unit). A minimum anti‐short cycle timer of 5 minutes will elapse before any compressor operation is permitted by the control board. Operate the unit for a minimum of 30 minutes before checking charge. Measure liquid service valve pressure by attaching an accurate R410A rated gauge to the 3/8” service port. Refer to Appendix C ‘Charging Chart’ for required sub cooling temperatures. For every 1 lb of additional refrigerant added, allow a sufficient time for the system to settle before taking another sub cooling indication. Complete the service sticker on the electrical box cover during installation. IMPORTANT: Before leaving the job, be sure to do the following: Ensure that all wiring and tubing is secure in unit before adding panels and covers. Securely fasten all panels / covers and ensure all fasteners remain tight. Tighten service valve stem caps to 1/12‐turn past finger tight. Leave Owner’s Manual with owner. Explain system operation and periodic maintenance requirements outlined in manual. Go over owner’s check list with the new Acadia owner. Fill out the Dealer Installation Checklist and place in customer file. Fill out the installation data sheet on the last page and mail or fax it to Hallowell International. ...
