2 to 5 Ton Heat Pump / Page 3 FEATURES COMPRESSOR Two -Stage Scroll Compressor • High volumetric efficiency • Uniform suction flow • Constant discharge flow • Quiet operation 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 • During the compression process, there are several pockets in the scroll that are compressing gas • Modulation is achieved by venting a portion of the gas in the first suction pocket back to the low side of the compressor thereby reducing the effective displacement of the compressor • A 24-volt DC solenoid valve inside the compressor controls staging • When the 3-way solenoid is energized it moves the lift ring assembly to block the ports and the compressor operates at full -load or 100% capacity • When the solenoid is de -energized the lift ring assembly moves to unblock the compressor ports and the compressor operates at part -load or approximately 67% of its full -load capacity • The 'loading" and "unloading" of the two stage scroll is done `on the fly" without shutting off the single -speed compressor motor between stages • Low gas pulses during compression reduces operational sound levels • Compressor motor is internally protected from excessive current and temperature • Compressor is installed in the unit on specially formulated, resilient rubber mounts for better sound dampening and vibration free operation Crankcase Heater • Protects against refrigerant migration that can occur during low ambient operation Optional Accessories Compressor Sound Cover • Reinforced vinyl compressor cover • 1-1/2 inch thick batt of fiberglass insulation • Hook and loop fastening tape on all open edges 16HPX -

Thermostat • Thermostat is not furnished with unit • Lennox Price Book for selection Blower Relay Kit (for use with furnaces equipped with constant torque blower motors) • Allows furnace blower speed changes when matched with two -stage heat pumps Compressor Hard Start Kit • Single-phase units are equipped with a PSC compressor motor • This type of motor normally does not need a potential relay and start capacitor • In conditions such as low voltage, kit may be required to increase the compressor starting torque NOTE - Hard start kit is required in applications where the supply voltage is less than 230V. Indoor Blower Off Delay Relay • Delays the indoor blower -off time during the cooling cycle Indoor Blower Speed Relay Kit • Relay kit provides the option of changing blower speeds on standard permanent split capacitor (PSC) multi -tap blower motors during cooling operation • Provides optimum humidity control conditions by automatically reducing indoor blower speed during continuous fan operation or low stage compressor operation to reduce humidity levels Low Ambient Kit • Heat pump can operate in the cooling mode down to 45°F outdoor air temperature without additional controls • Allows unit to operate properly down to 30°F in the cooling mode NOTE - Crankcase heater and freezestat should be installed on compressors equipped with a low ambient kit. NOTE - A compressor lock -out thermostat should be added to terminate compressor operation below recommended operation conditions.

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.
