Lennox LCH092H Installation and operation manual

Corp. 1009-L7
Revised 05/2020
LCH SERIES
Service Literature
7.5 to 12.5 ton
38.1 to 70.3 kW
LCH092 through 152U
The LCH092H, 094U, 102H, 120H, 122U, 150S, 150H and
152Uunits are configure to order units (CTO) with a wide
selection of factory installed options.
Cooling capacities range from 7.5 to 12.5 tons (38.1 to
70.3 kW). All units are equipped with two compressors.
Optional electric heat is factory-or field-installed. Electric
heat operates in single or multiple stages depending on the
kW input size. 7.5kW to 45kW heat sections are available
for the 092 & 102 and 15kW to 60kW heat sections are
available for 120 &150.
Ultra-high efficiency units are available with an optional di
rect drive blower or belt drive blower equipped with a sup
ply air inverter. Standard and high efficiency units are
available with a belt drive blower equipped with an option
al supply air inverter. The blower will operate at lower
speeds when demand is low and increase to higher
speeds when demand is high.
Standard and high efficiency units come standard with a
lightweight, all-aluminum condenser coil; optional, fin/
tube condenser coils are available. Ultra-high efficiency
units come standard with a tube/fin condenser coil.
Ultra high efficiency units come standard with two single-
speed compressors plumbed in tandem to form a single re
frigerant circuit.
All LCH units are designed to accept any of several different
energy management thermostat control systems with mini
mum field wiring. Factory or field provided control options
connect to the unit with jack plugs. When "plugged in" the
controls become an integral part of the unit wiring.
Information contained in this manual is intended for use by
qualified service technicians only. All specifications are
subject to change. Procedures outlined in this manual are
presented as a recommendation only and do not super
sede or replace local or state codes.
If the unit must be lifted for service, rig unit by attaching four
cables to the holes located in the unit base rail (two holes at
each corner). Refer to the installation instructions for the
proper rigging technique.
WARNING
Improper installation, adjustment, alteration, service
or maintenance can cause property va, personal in
jury or loss of life. Installation and service must be
performed by a licensed professional HVAC installer
or equivalent, service agency, or the gas supplier
