XC14 - 1.5 to 5 Ton Air Conditioner / Page 3
REFRIGERATion SYSTEM (C0NTINUED)
Outdoor Coil Fan
Direct drive fan moves large air volumes uniformly
through entire condenser coil for high refrigerant cooling
capacity.
Vertical air discharge minimizes operating sounds and
eliminates damage to lawn and shrubs.
Fan motor has sleeve bearings and is inherently
protected.
Motor totally enclosed for maximum protection from
weather, dust and corrosion.
Fan guard constructed of corrosion-resistant PVC
(polyvinyl chloride) coated steel.
Fan service access accomplished by removal of fan
guard.
Copper Tube/Enhanced Fin Coil
Lennox designed and fabricated coil.
Ripple-edged aluminum ns.
Copper tube construction.
Lanced ns provide maximum exposure of n surface to
air stream resulting in excellent heat transfer.
Fin collars grip tubing for maximum contact area.
Flared shoulder tubing connections/silver soldering
construction.
Coil is factory tested under high pressure to ensure
leakproof construction.
Entire coil is accessible for cleaning.
Refrigerant Flow Control
Units applicable to expansion valve systems or RFC
systems when matched with specic evaporator coils.
RFCIV METERING SYSTEM
RFCIV:
Accurately meters refrigerant in system.
Refrigerant control is accomplished by exact sizing of
refrigerant metering orice.
The principle involves matching indoor coil with proper
bore size of orice in metering device.
Equalizes pressure shortly after compressor stops, unit
starts unloaded, eliminating need for additional controls.
Furnished with air conditioner.

High Capacity Liquid Line Drier
Furnished with unit for eld installation.
Approved for use with R-410A systems.
Traps any moisture or dirt that could contaminate the
refrigerant system.
High Pressure Switch
Shuts off unit if abnormal operating conditions cause the
discharge pressure to rise above setting.
Protects compressor from excessive condensing
pressure.
Manual reset.
OPTIONS
Expansion Valve Kits
Must be ordered extra and eld installed on certain
indoor units.
See TXV/Orice Usage table.
Chatleff-style ttings.
Freezestat
Installs on or near the vapor line of the indoor coil or on
the suction line.
Senses suction line temperature and cycles the
compressor off when suction line temperature falls
below it’s setpoint.
Opens at 29°F and closes at 58°F.
Loss of Charge Switch Kit
Helps protect the compressor from damage due low
refrigerant charge conditions.
SPST, normally-closed switch, automatic reset switch
mounted on suction line.
Refrigerant Line Kits
Refrigerant lines (suction & liquid) are shipped
refrigeration clean.
Lines are cleaned, dried, pressurized and sealed at
factory.
Suction line fully insulated.
Lines are stubbed at both ends.
Not available for -060 models and must be eld
fabricated.
