important SAFETY INFORMATION INSTALLER: Please read all instructions before servicing this equipment. Pay attention to all safety warnings and any other special notes highlighted in the manual. Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING indicates a potentially hazardous situation that if not avoided, could result in personal injury or death.

Air conditioner INSTallATION General Information The S4BD series air conditioner is designed only for outdoor rooftop or ground level installations. This unit has been tested for capacity and efficiency in accordance with AHRI Standards and will provide many years of safe and dependable comfort, providing it is properly installed and maintained. Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards.
PAGE 4
Connecting Refrigerant Tubing Between the Indoor & Outdoor Unit CAUTION: When servicing, cover or seal openings to minimize the exposure of the refrigerant system to air to prevent accumulation of moisture and other contaminants. After outdoor and indoor unit placement has been determined, route refrigerant tubing between the equipment in accordance with sound installation practices.
PAGE 5
• Provide power supply for the unit in accordance with the unit wiring diagram, and the unit rating plate. Connect the line-voltage leads to the terminals on the contactor inside the control compartment. • Use only copper wire for the line voltage power supply to this unit as listed in Table 1. Use proper code agency listed conduit and a conduit connector for connecting the supply wires to the unit. Use of rain tight conduit is recommended.
PAGE 6
NOTES: • Factory installed modules have different thermostat demand signal wiring. Always follow manufacturer wiring instructions when replacing the module. • After the thermostat demand signal is connected, verify that 24 VAC across Y & C when demand is present. Interpreting the Diagnostic LED’s When an abnormal system condition occurs, the Comfort AlertTM module displays the appropriate ALERT and/or TRIP LED will flash a number of times consecutively, pause and then repeat the process.

Charging the Unit in AC mode at outdoor temperatures above 55° F for optimized sub-cooling of 10° F - 12° F. 1. With the system operating at steady-state, measure the liquid refrigerant pressure (in psig) at the outdoor unit service valve. 2. Measure the liquid refrigerant temperature (in Fahrenheit) at the service valve. 3. Determine the required liquid refrigerant pressure from the appropriate charging chart (Figures 3 - 9).
