FEATURES
Weather Resistant Cabinet — Heavy gauge galvanized steel
cabinet is subject to a five station metal wash process. This prepara-
tion process results in a perfect bonding surface for the finish coat
of baked -on enamel. The outdoor enamel paint finish gives the
cabinet long lasting protection from the weather. Drainage holes
are furnished in the base and base channels for moisture removal.
Heavy duty channels under the base raise the unit off the mount-
ing surface away from the damaging moisture.
Accessible Control Box — Conveniently located for easy access.
All controls are pre -wired at the factory.
Dependable Compressor — Rugged and reliable compressor is
hermetically sealed, suction cooled and overload protected. Inter-
nally protected from excessive current and temperature. Operates
efficiently at low outdoor temperatures during heating mode.
Strategically located discharge muffler reduces sound level. A
crankcase heater is furnished and provides proper lubrication and
protection from slugging_ Running gear is spring mounted within
sealed housing. In addition, compressor is installed on resilient rub-
ber mounts in the unit, assuring quiet and vibration free operation.
Powerful Outdoor Fan — Efficient direct drive fan moves large
volumes of air uniformly through the entire outdoor coil resulting
in high refrigerant cooling capacity. Vertical discharge of air
minimizes operating sounds and eliminates hot air damage to lawn
and shrubs. Fan motor is totally enclosed for maximum protec-
tion from weather, dust and corrosion. A rain Shield on the motor
provides additional protection from moisture. Fan service access
is accomplished by removal of fan guard. Corrosion resistant PVC
coated steel wire fan guard is furnished as standard.
Copper Tube Outdoor Coil — Lennox designed and fabricated
coil is constructed of precisely spaced ripple -edge aluminum fins
machine fitted to seamless copper tubes. Precise coil circuiting
gives uniform refrigerant distribution for high efficiency. Extra large
four sided wraparound coil configuration provides extra large sur-
face area for excellent heat transfer with minimum air resistance.
Fins are equipped with collars that grip tubing for maximum con-
tact 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 tubing connec-
tions and silver soldering provide tight, leakproof joints. Long life
copper tubing is corrosion -resistant and easy to service. Coil is
factory tested under high pressure to insure leakproof construc-
tion. Corrosion resistant PVC coated coil guard is furnished as
standard. Entire coil is accessible for cleaning.
Refrigerant Line Connections, Electrical Inlets and Service
Valves — Vapor and liquid line connections are located outside
of the cabinet and are made with sweat connections. Brass ser-
vice valves prevent corrosion and provide access to refrigerant
system. Drier with internal check valve and strainer are factory in-
stalled in the liquid line. One-shot vapor valve, liquid line service
valve and gauge ports are accessible outside of the cabinet, A field
installed thermometer well is furnished. A sight glass is furnished
and factory installed. Refrigerant line connections, valves and field
wiring inlets are all conveniently located in one central area of the
cabinet. See dimension drawing.
Defrost Control — A clock timer defrost control is furnished as
standard equipment. It gives a defrost cycle (if needed) for every
45 or 90 minutes (adjustable) of compressor "on" time. A sensing
element mounted on the outdoor coil determines when the defrost
cycle is required. Defrost pressure switch on the liquid line ter-
minates cycle.
Expansion Valve — Designed and sized specifically for use in heat
pump system. Sensor is located on the suction line between rever-
sing valve and compressor thus sensing suction temperature in
any cycle. Factory installed and piped.
Reversing Valve — 4-way interchange reversing valve effects a
rapid change in direction of refrigerant flow resulting in quick
changeover from cooling to heating and vice versa. Valve operates
on pressure differential between outdoor unit and indoor unit of
the system. Factory installed and piped.
High Pressure Switch — Factory installed and wired. Protects
system from abnormal operating conditions. Manual reset.
Start Controls — Furnished and factory installed. Provides
assistance for compressor start under loaded conditions or in the
event of low voltage.
Suction Line Accumulator (HP18-461V, 510V, 650V models
only) — Factory installed and piped. Traps and prevents large
amounts of liquid refrigerant from flooding directly into the com-
pressor and causing damage on start-ups and refrigerant cycle
change.
Thermostat (Optional) — Thermostat is not furnished with the
unit and must be ordered extra. See Accessories Section, Page
13 and the Lennox Price Book for selection.
Refrigerant Line Kits (Optional) — Lines are available in several
lengths and must be ordered extra. See Refrigerant Line Kit table
for selection. The refrigerant lines (vapor and liquid) are shipped
refrigeration clean. Lines are cleaned, dried, pressurized and sealed
at the factory. Vapor line is fully insulated. Lines are furnished with
a flare fitting (Indoor unit connection) on one end and less any
fitting (stubbed) on the opposite end for connection to the out
door unit. Refrigerant line length should not exceed 50 ft. in any
installation. If longer length lines are required, contact your Lennox
Division Service Manager.
Mounting Base (Optional) — Rugged mounting base provides
permanent foundation for outdoor units. High density polyethylene
structural material is lightweight, sturdy, sound absorbing and will
withstand the rigors of the sun, heat, cold, moisture, oil and
refrigerant. Will not mildew or rot. Can be shipped singly or in
packages of 6 to a carton. HP18-21 1V-261V-31 1V-410V models use
the MB 1-22 base (99C78) 22-1 /4" x 22-1 /4" x 3" shipping weight
10lbs. HPIB-461V thru -650V models use the M81-32 base (83C83)
32" x 34" x 3" shipping weight 15 lbs.
Outdoor Thermostat Kit (Optional) — An outdoor thermostat
can be used to lock out some of the electric heating elements on
indoor units where two stage control is applicable. Outdoor ther-
mostat maintains the heating load on the low power input as long
as possible before allowing the full power load to come on the line.
Thermostat kit (LB-29740BA) and mounting box (M-1595) must
be ordered extra.
Check and Expansion Valve Kits (Optional) — Must be
ordered extra and field installed on indoor units. See ARI Ratings
table for kit requirement.
Approvals — Units have been tested with matching indoor units
in the Lennox research Laboratory environmental test room and

cedures and in accordance with ARI Standard 210/240-89. In ad-
dition, units are U. L. Listed and have been sound rated in the Len-
nox reverberant sound test room and rated in accordance with ARI
Standard 270-84. Units and components within are bonded for
grounding to meet safety standards for servicing required by U. L.
and N.E.C.

FEATURES
Durable Cabinet - Constructed of heavy gauge galvanized steel and
completely insulated with thick fiberglass insulation. The cabinets are subject
to a five station metal wash process before painting. This preparation
process results in a perfect bonding surface for the attractive finish coat
of baked -on enamel. Removable panels provide complete service access.
Lennox Evaporator Coil - Extra large surface area of Lennox designed
coil provides maximum cooling efficiency, excellent heat transfer and low
air resistance. Precise circuiting gives uniform refrigerant distribution.
Lennox fabricated coil is constructed of precisely spaced ripple -edged
aluminum fins fitted to durable seamless copper tubes. Fins are strength-
ened to resist bending and are equipped with collars that grip tubing for
maximum contact area. Flared shoulder tubing joints and silver soldering
provide tight, leakproof joints. Long life copper tubing is easy to field service.
Coil is thoroughly factory tested under high pressure to insure leakproof
construction. CB18 models are equipped with dual coils in an "A"
configuration. CBS18 models have a single slab coil.
Drain Pan - Deep, corrosion resistant drain pan has dual pipe drains
extended outside of cabinet for ease of connection. See dimension
drawings.
Refrigerant Line Connections - Suction and liquid lines are equipped
with flare fittings and extend outside of the cabinet for ease of connection.
CB18/CBS18-65 suction line requires sweat connection. See dimension
drawing for location.
Transformer and Blower Cooling Relay (Furnished) - A 24 volt
transformer and blower cooling relay are furnished as standard equipment
and are factory installed- A terminal block is also furnished as standard.
Powerful Blower - Equipped with a Lennox designed and built direct
drive blower. Each blower is statically and dynamically balanced as an
assembly before it is installed in the unit. Multispeed motor is resiliently
mounted. A choice of blower speeds is available. See blower performance
charts. Change of blower speeds is easily accomplished by a simple change
in wiring.
Electric Heat (Optional) - Additive electric heaters field install internal
to the unit cabinet and are available in several kw sizes, see Electric Heat
table. The helix wound nichrome bare heating elements are exposed directly
in the air stream resulting in instant heat transfer, low element temperatures
and long service life. Each heating element is equipped with accurately
located limit control with fixed temperature off setting and automatic reset.
In addition, elements have supplemental thermal cutoff safety fuses
providing positive protection in case of excessive temperatures. Cutoff fuses
are mounted external to the element face plate for quick and easy
replacement. Thermal sequencer relay brings the heating elements on and
off line, in sequence and equal increments, with a time delay between each
element. Sequencer also initiates and terminates blower operation. Heating
control relay(s), is furnished as standard. Control box and access cover
are constructed of heavy gauge galvanized steel. Heaters are factory
assembled with controls installed and wired and only require plug-in field
connection.
Filter Kit (Optional) - Kit must be ordered extra and field installed. Filter
box installs on return air opening external to the unit cabinet. A throwaway
frame type filter is furnished on kits for CB18 up-flo models. Filter kits for
CBS18 horizontal models are field assembled. Filter(s) are not furnished
on kits for CBS18 horizontal models and must be ordered extra. Filter box
has an access panel for removal and replacement of filter. See specifica-
tion table and dimension drawings for details.
Expansion Valve Kits (Optional) - Kits must be ordered extra and field
installed on the blower -coil unit. See kit table for requirement.
