2.- INSTALLATION
2.1.- INSTALLATION GUIDELINES
2.2.- OPTIONAL OPERATIONS PRIOR TO UNIT INSTALLATION:
The unit must be transported in a HORIZONTAL POSITION on its metal legs. Any other position may cause serious
damage to the machine. When the unit is received, it should be checked to ensure that there are no knocks 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 explaining on the transport agent’s delivery notice why the machine is
unacceptable. Any complaint or claim made subsequently 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.
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 nece-
sary 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.
�ENTILATION FOR CIC-CIH UNITS IS PRO�IDED BY:
1.- Centrifugal fan (single or double).
2.- Drive motor.
3.- Pulley fixed to the fan.
4.- Adjustable pulley on the fan motor.
5.- Pulley belt.
6.- Base of the motor with displacement system for tensioning belts.
7.- Tensioning screw.
REGULATING AIRFLOW AT THE FANS
The unit fan has an adjustable pulley on the drive motor so that, when the fan is switched off, the pulley diameter can
be adjusted to modify the unit’s air flow, as required.
1. Fixed part. 2. Moving part. 3. Fixing screw.
CLOSE PULLEY:
To increase the air flow from the fan, turn
the moving part in direction “B”. (Clockwise).
OPEN PULLEY:
To reduce airflow, turn in direction “A”.
(Anticlockwise).
ADJUSTABLE PULLEYS
SIMPLE PULLEY DOBLE PULLEY
TENSION OF BELTS
The belts can be easily tensioned by means of the tensioning screw
incorporated into the base of the motor in the transmission unit,
which also makes it easy to carry out servicing properly.
When the tensioning screw is turned, the fan motor is moved
sideways in order to tension the pulley. DISPLACEMENT
If there are problems of height, the transport
supports can be removed by unscrewing them from
the base. (Units 020S to 085D).

2.- INSTALLATION
2.3.- SER�ICE SPACE
2.4.- DRAINAGE
All units have a 3/4” steel threaded drainage pipe welded to the condensation tray.
Free space should be left to enable access for servicing, in order to check
the installation of the cables, drainage connections, electrical installation
and cleaning filters, as well as to give easy access to the unit.
Drainage pipes will be fitted for each tray through a siphon with a height
difference of 80 mm. to avoid drainage problems from the depression formed
by the fans. The pipes should have a 2% slope to enable condensation to be
drained easily.
Also tip the unit slightly (2%) toward the drainage side. Check that the
condensation trays are clean and free of dirt and other debris from the
installation work and that water drains correctly.

2.5.- REFRIGERANT CONNECTIONS
The unit is supplied with gas and liquid lines, sealed with copper caps.
THE UNITS ARE SUPPLIED WITH NITROGEN GAS. THIS MUST BE REMO�ED BEFORE PROCEEDING AS
FOLLOWS:
1 Remove the nitrogen gas through the top and bottom 5/16” service ports, leaving a vacuum as a safety measure.
2 Remove the caps from the connecting pipes.
3 Braze the connecting pipes.
(When brazing refrigerant pipes, nitrogen gas must be supplied through the service ports into the pipes to remove
any air).
DURING INSTALLATION OPERATIONS, KEEP GAS AND LIQUID PIPES CO�ERED, IN ORDER TO PRE�ENT
HUMIDITY AND DIRT FROM GETTING INTO THEM.
TAKE SPECIAL CARE TO ENSURE THAT REFRIGERANT PIPES ARE INSULATED.
A�OID COLLAPSE ON PIPE LINES INSTALLATION.
- 100D and 120D units model use different sizes of pipe connections:
big size for circuit 1 and small size for circuit 2.
Please be sure to connect indoor unit circuits C1 and C2 to the corresponding C1 and C2 circuits of the outdoor unit.

PROTECTION AGAINST FREEZING:
• Use glycol water. GLYCOL IS THE ONLY EFFECTI�E
PROTECTION AGAINST FREEZING.
This kit includes a safety thermostat with a probe located inside the
hot water coil. When the temperature drops below 4ºC, the unit will
stop in order to protect the hot water coil and to prevent the unit from
working with very low evaporating temperatures.
Five wires must be added between indoor and outdoor unit with this
option.
Hot water coil includes regulating valve:
- ON/OFF for standard and multi split.
- Proportional (0-10�), for C50 version.
A HEATING COIL FROZEN DUE TO LOW AMBIENT CONDITIONS IS NOT CO�ERED BY THE WARRANTY.
2.- INSTALLATION
You must ensure that manual or automatic air vents have been installed on all high points in the system. In order to
drain the system, check that drain valves have been installed at all low points of the system.

* Mixing and return fan sections can be together or not.
1.- OPERATION
The control compares the values of temperature/enthalpy between outside air and room air by means of the probes;
if there is a negative difference and the safety elements allow (discharge temperature probes) then the control acts
on the servomotor, which opens the outside damper and closes the return damper, allowing cool outside air to enter
the room.
The damper is proportionally regulated.
If there is not a great demand for air indoors, it may be enough just to have free cooling to condition the room. If there
is a greater demand for air, the free cooling and the unit may need to be working in different cooling mode stages.
2.- SUPPLY AND INSTALLATION
The free cooling option can be delivered as a packaged system or as a split system.
The mixing section will be delivered with the unit for models 020S to 045D and as a split system for the remaining
models.
Return fan section will be delivered with the unit.
