2.1.- INSTALLATION GUIDELINES
2.2.- OPTIONAL OPERATIONS PRIOR TO UNIT INSTALLATION:
VENTILATION FOR CIC-CIH UNITS IS PROVIDED 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.
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 necesary 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.
If there are problems of height, the transport supports can be removed by unscrewing them from
the base
(Units 020S to 085D).
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).
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.

2.3.- SERVICE SPACE
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.
2.4.- DRAINAGE
All units have a 3/4” steel threaded drainage pipe welded to the condensation tray.
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. UNIT
Min. 80 mm
Inspection and cleaning cap.
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 REMOVED 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 COVERED, IN ORDER TO PREVENT HUMIDITY AND
DIRT FROM GETTING INTO THEM.
TAKE SPECIAL CARE TO ENSURE THAT REFRIGERANT PIPES ARE INSULATED.
AVOID 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.
2. INSTALLATION
Legislation does not allow refrigerant gas emissions to the atmosphere, so the refrigerants have to be recycled to avoid being
released to the atmosphere. Those recycled refrigerants shall be processed afterwards by an authorized waste manager.
Those components derived from the recycling of the unit have to be managed by authorized waste manager or be left in local
waste facilities according the local normative in each country.

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 (0-10V).
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.

FREE COOLING
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.
