AIR CONDITIONER INSTALLATION General Information The S5BP 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 A.R.I. 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.
Ground Level Ground level installations must be located according to local building codes or ordinances and these requirements: • Clearances must be in accordance with those shown in Figure 2 (page 6). • A suitable mounting pad (Figure 3) must be provided and be separate from the building foundation. The pad must be level and strong enough to support the unit’s weight. The slab height must be a minimum of 2” (5 cm) above grade and with adequate drainage.
ELECTRICAL WIRING WARNING: To avoid risk of electrical shock, personal injury, or death, disconnect all electrical power to the unit before performing any maintenance or service. The unit may have more than one electrical supply. Label all wires prior to disconnection when servicing the unit.
Unbalanced 3-Phase Supply Voltage Voltage unbalance occurs when the voltages of all phases of a 3-phase power supply are no longer equal. This unbalance reduces motor efficiency and performance. Some underlying causes of voltage unbalance may include: Lack of symmetry in transmission lines, large single-phase loads, and unbalanced or overloaded transformers. A motor should never be operated when a phase imbalance in supply is greater than 2%.
START UP & ADJUSTMENTS Pre-Start Check List Verify the indoor unit is level and allows proper condensate drainage. Verify the outdoor coil and top of the unit are free from obstructions and debris, and all equipment access/ control panels are in place. Verify that the duct work is sealed to prevent air leakage. Verify that the line voltage power leads are securely connected and the unit is properly grounded.
After refrigerant line connections are completed, it is required that you leak check and evacuate the indoor section and all line connections (using proper methods) before finalizing the full system refrigerant charge. For final charges based on matched systems and specified line lengths, see physical and electrical specifications (Table 4, page 13).
COMPONENT FUNCTIONS Anti-Short Cycle Timer (ASCT) A protective short cycle timer is factory installed and located in the control panel of the outdoor section. If power to the compressor low voltage control circuit is interrupted, the outdoor unit will not energize for approximately 5 minutes. High Pressure Switch (HPS) A high-pressure switch is factory-installed and located in the liquid line internal to the outdoor unit.

S5BP CHARGING CHARTS - COOLING ONLY Application Notes on the Use of Charging Charts • This equipment’s cooling system contains refrigerant under high pressure. Always use safe and environmentally sound methods when handling refrigerant handling or servicing the unit. Review the factory literature and safety warnings prior to servicing. • When repairing system leakages, always use a nitrogen (inert) gas to protect the refrigerant system and pressure check the repair before re-charging.
