2.- INSTALLATION
2.1.- INSTALLATION GUIDELINES
ALL INSTALLATION, SERVICE and MAINTENANCE operations must be carried out
by QUALIFIED PERSONNEL.
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.
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).
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.

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.
ADJUSTABLE PULLEYS
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
1m
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.
UNIT
Mín.
2% 80mm
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.
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.
C2
- 100D unit model uses different sizes of pipe connections: big size for
circuit 1 and small size for circuit 2.
C1
Please be sure to connect indoor unit circuits C1 and C2 to the corresponding C1 and C2 circuits of the outdoor unit.

HOT WATER COIL
PROTECTION AGAINST FREEZING:
• Use glycol water. GLYCOL IS THE ONLY EFFECTIVE
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), for C50 version.

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.
A HEATING COIL FROZEN DUE TO LOW AMBIENT CONDITIONS IS NOT COVERED BY THE WARRANTY.
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.

Check that drainage connections and their fixtures are secure and that the level of the unit is tipped toward the drain.
Inspect the condition of the ducts and grilles (grilles are clean and clear of obstructions, no breaks in the duct, etc.).
Check that the power supply is the same as stated on the Rating Plate and is in accordance with the electrical diagram
for the unit and that cable sizes are correct.
Check that the electrical connections are tightened onto their terminals and to earth.
Inspect the Air Filter, which should be in its housing and correctly positioned (the metal grille should be facing inwards).
Check with your hand that the fan turns freely.
SKETCH FOR THE STANDARD UNIT CONFIGURATION IN DOUBLE CIRCUIT UNITS
LOCATION
The unit can be installed outside (if an outdoor kit installation has been ordered). If this is installed, air entry and exit ducts should
be fitted. The indoor unit should be assembled on bases that have been prepared beforehand. It should stand on absorbent and
anti-vibration material to avoid vibrations being transmitted to the structure of the building.

4.1.- PREVENTIVE MAINTENANCE
PREVENTIVE MAINTENANCE HELPS TO AVOID COSTLY REPAIRS, SO PERIODIC INSPECTIONS ARE REQUIRED:
GENERAL CONDITION OF THE HOUSING:
F
ittings, paintwork, damage from knocks, rust spots, levelling and supporting, condition of the shock absorbers, if installed,
bolted on panels, etc.
- ELECTRICAL CONNECTIONS:
C
ondition of hoses, tightness of screws, earthing, current draw of the compressor and fans and checking that the unit is receiving
the correct voltage.
- COOLING CIRCUIT:
C
heck that pressure values are correct and that there are no leaks. Check that there is no damage to the pipe insulation,
that the state of the batteries is correct and that there are no material clogging the duct and obstructing the air flow, etc.
- DRAINS:
Check that water drains correctly and that the drain trays are clean.
- FAN:
Check that fans turn freely and in the correct direction without excessive noises.
- AIR FILTER :
The air filter can be removed through the side by sliding it over the rail or downwards.
(See figure).
F
or downwards removal, remove the two profiles that support it (depending on the model)
which are under the filter guide rail and screwed onto the unit.
SIDE REMOVAL
The filter should be cleaned with a vacuum cleaner or washed in soapy water.
The frequency for cleaning or changing the air filters will depend on the quality air in the area (fumes, vapors, suspended dust
particles, etc.).
Remember that the metal grille should always be toward the inside of the unit.
Remember that the Control Panel may program a notification parameter, for cleaning or replacement of air filters depending on the number of hours of fan operation in the indoor section.

4.2.- FAULT DIAGNOSIS
DIRTY FILTER INDICATION
If the filters are dirty, the detector activates an alarm, but only if the fan is ON.
SMOKE DETECTOR
In this case it would initiate shutdown sequence the unit, fully close the return air damper and open the fresh air damper up to 100% and send an alarm signal to the unit.
