AIR CONDITIONER INSTALLATION General Information The NS6QD 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.H.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.
Connecting Refrigerant Tubing Between the Indoor & Outdoor Unit CAUTION: This system uses R-410A refrigerant with POE oil. 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.
Line Voltage • A wiring diagram is located on the inside cover of the electrical box of the outdoor unit. The installer should become familiar with the wiring diagram before making any electrical connections to the outdoor unit. • An electrical disconnect must be located within sight of and readily accessible to the unit. This switch shall be capable of electrically de-energizing the outdoor unit.
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 air filters are cleaned and properly installed. Verify duct work is sealed to prevent air leakage. Verify line voltage power leads are securely connected and the unit is properly grounded.
• If the pressure measured in Step 1 is less than the required liquid refrigerant pressure determined in Step 3, there is too little charge in the system. Add refrigerant and repeat Steps 1 through 3 until the system is correctly charged. AIR CONDITIONER MAINTENANCE WARNING: To prevent 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.

NS6QD 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.
