REFRIGERATION SYSTEM
Refrigerant
Non−chlorine, ozone friendly, R−410A.
Unit pre−charged with refrigerant.
See Specification table.
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 fins.
Copper tube
construction.
Lanced fins provide maximum exposure of fin surface to
air stream resulting in excellent heat transfer.
Fin collars grip tubing for maximum contact area.
Inverted coil circuiting prevents ice buildup at coil base in
low ambients. Discharge gas enters bottom of coil during
defrost and heat of refrigerant flows counter to water
drainage resulting in extremely clean and unobstructed
fins and tubes.
Fin spacing allows rapid and complete water drainage.
Flared shoulder tubing connections/silver soldering
construction.
Coil is factory tested under high pressure to insure
leakproof construction.
Entire coil is accessible for cleaning.
