Applications —Lennox designed and built up-flo evaporator
coils can easily be installed with most Lennox up-flo fur-
naces. Coils match most plenum openings of Lennox fur-
naces. See Coil to Furnace Selector in this bulletin for more
information. See condensing units bulletins (section Cooling
Units — Condensing Units) for evaporator unit applications
and cooling capacities. See heat pump outdoor unit bulletins
(section Heat Pumps — Matched Remote Systems) for indoor
coil applications and cooling and heating capacities. See
FM21 bulletin in Heat Pumps— Matched Remote Systems for
more information.
Construction — Lennox designed and fabricated coils are
constructed of precisely spaced ripple -edged enhanced alu-
minum fins machine fitted to rifled Cooper tubes. Lanced fins
allow'for maximum exposure of fin surface to air stream.
Copper rifled -tubing construction provides long coil life and
ease of service. Rifled tubing provides superior refrigerant
flow resulting in maximum heat transfer. Twin coils as-
sembled in an "A" configuration provides extra large surface
and contact area for maximum efficiency. Fins have collars
that grip tubing for maximuT contact area resulting in excel-
lent heat transfer. Flared shoulder tubing joints and s ' ilver sol-
dering provide tight leakproof joints. Coils are thoroughly
tested under pressure to insure leakproof construction.
Drainpan is cons * tructed of a non -corrosive polymer and has
dual 3/4 inch .(19 mm) f pt drain connections. Two-piece end
panel allows easy access for coil servicing and cleaning. Re-
frigerant lines are equipped with sweat connections on both
suction (vapor) and liquid line.
Fully Tested— Evaporator units have bee n thoroughly tested
with matching condensing and heat pump units in the Len-
nox Research Laboratory environmental test room. Air resis-
tance data is from tests conducted in the Lennox air test
chamber. Coil assemblies are shipped factory assembled and
ready for installation.
Check and Expansion Valve Kit Furnished— Check and expani-
Sion valve is factory installed on all models.
Adjustable CoflAdaptorBase Furnished— Adjustable adaptor
base is furnished with coils to provide quick and easy installa-
tion in a wide variety of applications. See Coil to Furnace Selec-
tor, dimension drawings and application drawings,
CF30-00 Non -Adjustable Adaptor Base (Optional) — Fixed
width base (46J43) is available for C22 installations with
G20E-Q5/6-150 model furnaces. See Specifications table, Coil
to Furnace Selector, dimension drawings and application
drawings.
Full Height Empty Coil Cabinet Cabinet (Optional) — Cabi-
nets are fully insulated with thick fiberglass insulation and are
constructed of heavy gauge steel with a deluxe baked -on
enamel paint finish, Bend -up flanges are provided in outlet
opening of cabinet for ease of plenum connection in conven-
tional. See Specifications tables, Empty Coil Cabinet to Fur-
nace Selector and dimension drawing.
Up -Flo tod. Twinning Kit (Optional) -7 Twinning kit
LB-65597A.(3OJ76) is available to operate two C22-41, C22-46
or C22-65 coils simultaneously with one HS17 condensing
unit and two furnaces. Kit contains necessary plumbing fit-
tings to interconnect coils. Must be ordered extra.
