AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL General Installation Information Safety Considerations Duct System All blower coil units/air coils must be installed as specified by the manufacturer’s installation instructions; however, the following recommendations should considered to minimize noise and service problems. WARNING: Before performing service or maintenance operations on a system, turn off main power switches to both units.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL General Installation Information cont. When utilizing the existing air coil or line set, only flushing compounds that vaporize should be used; which means they are packaged in a pressurized disposable cylinder. It is preferable to use a flushing agent that removes oil, water, and acid, plus, is biodegradeable and non-toxic. The flushing agent should be safe to use with both HCFC and HFC refrigerants.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL General Installation Information cont. In add-on Outdoor Split applications, the coil should be located in the supply side of the furnace to avoid condensation damage to the furnace heat exchanger. A high temperature limit should be installed upstream of the coil to de-energize the compressor whenever the furnace is operating. Without this switch, the Outdoor Split will trip out on high pressure.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL Water Quality In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time, lose heat exchange capabilities due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualified service mechanic, as special solutions and pumping equipment are required.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL Water Piping Residential split units are supplied standard with GeoLink swivel connections with P.T. ports. Flow Center Installation Flow centers FC1-GL or FC2-GL, as needed, may be internally mounted on the outdoor split, Two stub tubes with barbs are pre connected to the coax.

AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL The Aurora™ Control System Aurora ‘Base’ Control The Aurora ‘Base’ Control (ABC) System is a complete residential and commercial comfort system that brings all aspects of the HVAC system into one cohesive module network. The ABC features microprocessor control and HP, LP, condensate and freeze detection, over/ under voltage faults, along with communicating thermostat capability for complete fault detection text at the thermostat.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL The Aurora Control System cont. Aurora ‘Base’ Control Reset Configuration Mode The control is placed in reset configuration mode by holding the push button switch SW1 for 50 to 60 seconds. This will reset all configuration settings and the EEPROM back to the factory default settings. LED3 (green) will turn off when entering reset configuration mode. Once LED3 (green) turns off, release SW1 and the control will reset.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL The Aurora ‘Base’ Control System cont. Safety Features Over/Under Voltage Shutdown - An over/under voltage condition exists when the control voltage is outside the range of 18 VAC to 30 VAC. If the over/under voltage shutdown lasts for 15 minutes, the lockout and alarm relay will be energized. Over/under voltage shutdown is self-resetting in that if the voltage comes back within range of 18 VAC to 30 VAC for at least 0.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL The Aurora ‘Base’ Control System cont. Blower (G) - The blower will start immediately upon receiving a thermostat G command. If there are no other commands from the thermostat the ECM will run on “G” speed until the G command is removed. Regardless of blower input (G) from the thermostat, the blower will remain on for 30 seconds at the end of each heating, cooling, and emergency heat cycle.

AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL Refrigeration If an air handler manufactured by others is used then refrigerant should be added to the Affinity Split factory pre-charge. Refrigerant should be added for liquid line length. This should result in a slightly under-charged system exhibiting low subcooling and high superheat. As charge is added, the subcooling should rise and the superheat should fall.
AFFINITY DUAL-CAPACITY OUTDOOR SPLIT SERIES INSTALLATION MANUAL Refrigeration cont. Determining Subcooling 1. 2. 3. 4. Measure the temperature of the liquid line on the small refrigerant line (liquid line) just outside the split cabinet. This location will be adequate for measurement in both modes unless a significant temperature drop in the liquid line is anticipated. Measure the liquid line pressure by attaching refrigerant gauges to the schrader connection on the liquid line service valve.
