NOTE - Refer to the unit -mounted charging sticker to determine correct amount of charge required. 0 Outdoor Coil Fan • Direct drive fan • Vertical air discharge • Louvered steel top fan guard • Totally enclosed fan motor • Ball bearings • Inherently protected High Capacity Liquid Line Drier • Furnished with unit for field installation • Drier traps moisture or dirt • 100% molecular -sieve, bead type, bi-flow drier High Pressure Switch • Shuts off unit if abnormal operating conditions cause the discharge pressure to rise above setting • Automatic reset 13ACXN - 1.5 to 5 Ton Air Conditioner / Page 3 FEATURES REFRIGERATION SYSTEM (continued) Refrigerant Flow Control • Units applicable to expansion valve systems or RFC systems when matched with specific indoor coils RFCIV: • Accurately meters refrigerant in system • Refrigerant control is accomplished by exact sizing of refrigerant metering orifice • The principle involves matching indoor coil with proper bore size of orifice in metering device RFCIV METERING SYSTEM ORIFICE BODY RFCIV (On Coil) "BULLET" ORIFICE O-RING o/ LIQUID � LINE LIQUID LINE SCREEN SEAL NUT SWEAT CONNECTION • Equalizes pressure shortly after compressor stops, unit starts unloaded, eliminating need for additional controls Optional Accessories Expansion Valve Kits • Field installed on certain indoor units • See TXV Usage Table • Chatleff-style fittings Freezestat • Senses suction line temperature • Cycles compressor off when suction line temperature falls below it's setpoint • Opens at 297 and closes at 58°F • Installs on or near the discharge line of the evaporator or on the suction line Loss of Charge Switch Kit • Protects the compressor from damage due low refrigerant charge conditions • SPST, normally -closed switch • Automatic reset switch • Mounted on liquid line Refrigerant Line Kits • Refrigerant lines are shipped refrigeration clean • Lines are cleaned, dried, pressurized and sealed at factory • Suction line fully insulated • Lines are stubbed at both ends COMPRESSOR 0 Scroll Compressor • High efficiency with uniform suction flow • Constant discharge flow, high volumetric efficiency and quiet operation • Low gas pulses during compression reduces operational sound levels • Compressor motor is internally protected from excessive current and temperature • Muffler in discharge line reduces operating sound levels • Compressor is installed in the unit on resilient rubber mounts for vibration free operation Scroll Compressor Operation • Two involute spiral scrolls matched together generate a series of crescent -shaped gas pockets between them • During compression, one scroll remains stationary while the other scroll orbits around it • Gas is drawn into the outer pocket, the pocket is sealed as the scroll rotates • As the spiral movement continues, gas pockets are pushed to the center of the scrolls. Volume between the pockets is simultaneously reduced • When the pocket reaches the center, gas is now at high pressure and is forced out of a port located in the center of the fixed scrolls • During compression, several pockets are compressed simultaneously resulting in a smooth continuous compression cycle • Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency • Compressor is tolerant to the effects of slugging and contaminants. If this occurs, scrolls separate, allowing liquid or contaminants to be worked toward the center and discharged Optional Accessories Compressor Crankcase Heater • Protects against refrigerant migration that can occur during low ambient operation Compressor Sound Cover • Reinforced vinyl compressor cover • 1-1/2 inch thick batt fiberglass insulation • All open edges are sealed with a one -inch wide hook and loop fastening tape 13ACXN - 1.5 to 5 Ton Air Conditioner / Page 4 FEATURES CONTROLS Optional Accessories iComfort® M30 Smart Wi-Fi Thermostat • Wi-Fi-enabled, electronic 7-day, universal, multi -stage, programmable, touchscreen thermostat • 4 Heat/2 Cool • Auto -changeover • Dual -fuel control with optional outdoor sensor • Controls dehumidification during cooling mode and humidification during heating mode • Offers enhanced capabilities including humidification / dehumidification / dewpoint measurement and control, Humiditrol° control, and equipment maintenance reminders • Easy to read 4.3 in. color touchscreen (measured diagonally) • LCD display with backlight shows the current and set temperature, time, inside relative humidity, system status (operating mode and schedules) and outside temperature (optional outdoor sensor required) • Smooth Setback Recovery starts system early to achieve setpoint at start of program period • Compressor short -cycle protection (5 minutes) • Up to four separate schedules are available plus Schedule IQTM • One -Touch Away Mode - A quick and easy way to set the cooling and heating setpoints while away • Smart Away"" - Uses geo-fencing technology to determine when the homeowner is within a predetermined distance from the home to operate the system when leaving, away and arriving • Wi-Fi remote monitoring and adjustment through a home wireless network for desktop PCs, laptops and apps for smartphones or tablets • Smart home automation compatible with Amazon Alexa°, Google Assistant and IFTTT NOTE - See the iComfort° M30 Smart Wi-Fi Thermostat Product Specifications bulletin in the Controls section for more information.

AHRI STANDARD 210/240 Cooling or heating capacities are net values, including the effects of blower motor heat, and do not include supplementary heat. Power input is the total power input to the compressor(s) and fan(s), plus any controls and other items required as part of the system for normal operation. Units which do not have an indoor air -circulating blower furnished as part of the model, i.e., split system with indoor coil only, is established by subtracting from the total cooling capacity 1250 Btu/h per 1,000 cfm, and by adding the same amount to the heating capacity. Total power input for both heating and cooling is increased by 365 W per 1,000 cfm of indoor air circulated. 13ACXN - 1.5 to 5 Ton Air Conditioner / Page 10 REVISIONS Sections Approvals and Warranty LE--7 NNOX Description of Change Corrected compressor warranty. 0 A ©40HMI ,/MEMBER COMPANY �M C us ntertek Visit us at www.lennox.com For the latest technical information, www.LennoxPros.com Contact us at 1-800-4-LENNOX NOTE - Due to Lennox' ongoing commitment to quality, Specifications, Ratings and Dimensions subject to change without notice and without incurring liability.
