1.- GENERAL CHARACTERISTICS
1.7.- AVAILABLE OPTIONS
ELECTRIC HEATER
Optionally, these units can contain shielded element electric
heating batteries that are mounted on the inside of the unit in
the schematic opposite.
The electric heater must get its power from the unit’s electrical
box.
MAIN SWITCH
The main switch is located on the access panel to the electrical box in such a way that the unit is disconnected
when the panel is opened.
(Refer to the size diagram on pages 7 to 10 to see the position of the electrical box access panel).
Check to make sure that the main switch is large enough to handle the current for the unit if electric heaters are
installed.
PHASE SEQUENCER (THREE-PHASE UNIT)
The phase sequencer is located in the electrical box in the outdoor section, thus assuring that the unit will not
begin operation while the phase connection of the compressor is not correct. Should this occur, then just switch
two phase connections.
ON/OFF CONDENSATION PRESSURE CONTROL (MODELS 10-12-16)
The condensation pressure control consists of a pressure switch, which starts and stops the outdoor fan regulating
the condensation temperature, thus the unit will be able to operate in the cooling cycle when the outdoor
temperature is below 19ºC.
HOT GAS BYPASS VALVE
The purpose of the BYPASS valve is to make it possible for the unit to operate at low outdoor temperatures (under
0°C), to be used in cooling-only and head-pump units.
It regulates the capacity of the compressor by injecting hot gas from the compressor discharge side to the
evaporator.
CONTROL USING A PROGRAMABLE CONTROLLER:
With the programmable controller option, the desired temperature can be programmed in the area 24 hours a day,
7 days a week.
REMOTE ROOM-TEMPERATURE SENSOR, REMOTE DUCT SENSOR
This sersors may be used in conjunction with remote controller, allowing the controller to be mounted in a room
away from the conditioned space.
- REMOTE DUCT SENSOR: The sensor will be located in the return-air duct, detecting the air temperature of the
air being air-conditioned.
- REMOTE ROOM-TEMPERATURE SENSOR: The sensor will be placed in the area to be air-conditioned.
FREECOOLING THERMOSTAT KIT
The Freecooling Thermostat Kit will only operate in cooling-only or heat-pump units. This is an energy saving
system that regulates the dampers doors through which outdoor air is taken in when the outdoor temperature is
lower than the area to be air-conditioned.
This kit consists of the damper, a motor, power card and a controller with specific programming, safety thermostat
for air discharge and outdoor sensor, completely factory-assembled.

1.7.- AVAILABLE OPTIONS
Air filter
SOUND MUFFLER
Available for models 16, 22, 24, 28, 30.
Field assembled, designed to be installed at the extractor
opening of the outdoor unit in order to reduce noise,
particularly when the outdoor unit is installed without ducts,
free discharge.
This kit contains the sound muffler and adapter parts for
fixing it to the unit.
CRANKCASE HEATER (COOLING-ONLY UNITS)
When the unit is operating at low outdoor temperatures it is advisable to fit a crankcase heater.
The purpose of the heater is to keep the oil in the compressor at the correct temperature while the compressor is
stopped so that it can be properly lubricated when started again.
OUTDOOR MOUNTING KIT
Field assembly.
This kit is comprised of an air filter and grille for outdoor air intake which should be installed on the suction side
of the outdoor unit, and the anti-rain hood which should be installed on the discharge side of the outdoor fan.
OUTDOOR AIR FILTER KIT
Field assembly.
The outdoor air filter should be installed on the outdoor air inlet of the outdoor unit and is recommended when
working in heavily contaminated areas that may soil or clog the outdoor Coil.

2.- INSTALLATION
Wood
block
Securing
screw
If unloading and placement require the use of a
crane, then secure the suspension cables as
shown in the figure.
The unit must be transported in a HORIZONTAL POSITION on its metal bedplate profiles and TRANSPORTATION
BLOCKS. Any other position may cause serious damage to the machine. When the unit is received, it should be
checked to assure that there are no bumps or other damage, following the instructions on the packaging. If there
is damage, the unit may be rejected by notifying the LENNOX Distribution Department and reporting why the
machine is unacceptable on the transport agent’s delivery notice. Any later complaint or claim made to the
LENNOX Distribution Department, for this type of anomaly, cannot be considered under the Guarantee.
Sufficient space must be allowed to facilitate placement of the unit. The unit may be mounted outdoors. There
should be NO possibility of flooding if floor mounted.
2.1.- PRELIMINARY PREPARATIONS
All INSTALLATION, SERVICE and MAINTENANCE operations
must be carried out by QUALIFIED PERSONNEL.
When positioning the unit, be sure that the Rating Plate will always be visible since this
data will be necessary to assure proper maintenance.
The units are designed to be installed with ducts, calculated by qualified technical staff. The joints to be used
between ducts and the openings to the unit should be Elastic Joints. Avoid the use of BYPASS joints between the
extraction air and input air in both the outdoor and indoor sections. The structure where the unit is placed must
be able to support the weight of the unit during operation.
2.2.- UNIT RECEPTION
All the units have Metal Bedplate Profiles and Wooden Blocks for transportation.
These wooden blocks must be removed when positioning the unit in its final position.
To remove the transportation blocks,
remove the screw and slide the block along the metal profile.

The bedplate is made up of three galvanized metal channels, capable of withstanding the weight of the units
whether hung from the ceiling or mounted on the floor.
If the unit is floor mounted, then the profiles should be isolated with shock absorbing material such as anti-vibration
or pads. If used, consult the weight distribution table below to make the correct selection. Keep in mind that fans
rotate at approximately 850 rpm.
If the unit is hung, M-10 threaded rods should be used along with shock absorbing ceiling supports.
