Page 8: Installation Steps
Ensure the mounting pad will not shift or swell from seasonal frost heaves. The Acadia outdoor unit must be mounted on Hallowell Approved snow stands to allow water to drain during a defrost cycle and so ice build-up will not interfere with the unit operation. -
Page 9: Step 3 - Clearance Requirements
INSTALLATION STEPS (NOTE) On rooftop applications, mount on a level platform or frame. Place the Acadia outdoor unit above a load-bearing wall and isolate the unit and line set from the structure. Arrange supporting members to adequately support the system and minimize transmission of vibration to the building. -
Page 10: Step 4 - Install Indoor Air Handler And Expansion Device
There is only one Hallowell Approved air handler. Any other air handler installed has no guarantee on the efficiency, life expectancy, and/or performance. Indoor air handlers used with an Acadia outdoor unit must be capable of operating with a minimum of 2 blower speeds. -
Page 11: Step 5-Making Piping Connections
The TXV should be mounted as close to the indoor air handler coil as possible with the thermal bulb securely mounted and insulated. (NOTE) When using the Hallowell matched air handler and/or TXV kit, see (Appendix A – Factory Supplied Air Handler TXV Kit Installation Instructions). IMPORTANT: If replacing an existing hot air furnace, make sure the ductwork is sized appropriately for the airflow needed by the Acadia. - Page 12 INSTALLATION STEPS IMPORTANT: Keep the refrigerant lines free of debris and moisture. Ensure all line set tubing meets R-410A refrigerant requirements. Install the line set with as few bends as possible, reducing the number of 90° bends where possible. Care must be taken not to damage or kink the tubing.
-
Page 13: Step 6 - Making Electrical Connections
INSTALLATION STEPS IMPORTANT: Open all service ports and all flow-control devices once the system is piped. Do not leave the system open to the atmosphere. The POE oil in the compressors is extremely susceptible to moisture absorption. Always keep the ends of the tubing sealed during the installation and free of debris. - Page 14 INSTALLATION STEPS (NOTE) Use a minimum 10 conductor, 18 AWG wire harness for control connections between the thermostat, indoor air handler unit, and the Acadia outdoor unit. A minimum 10 conductor, 18 AWG wire harness must be used to prevent incorrect wiring of the system.
