must be carried out by QUALIFIED PERSONNEL.

The unit must be transported in a VERTICAL POSITION on its metal mounting frame. Any other position may cause

serious damage to the machine. When the unit is received, it should be checked to assure that it has received no

shocks 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 stating why the machine is unacceptable on the transport agent’s

delivery note. Any later complaint or claim made to the LENNOX Distribution Department for this type of damage

cannot be considered under the Guarantee.

Suffi cient space must be allowed to facilitate installation of the unit.

The unit may be mounted outdoors. When the unit is mounted on the fl oor, ensure that the position is not subject

to fl ooding.

When positioning the unit, be sure that the Rating Plate is always visible since this data
will be necessary to ensure correct maintenance.

The units are designed to be installed with ducts designed by qualifi ed technical staff. The joints to be used between

ducts and openings in the unit should be Elastic Joints. Avoid the use of BYPASS joints between the extraction air

and input air. The structure where the unit is placed must be able to support the weight of the unit during operation.

2.2.- UNIT ACCEPTANCE

All units have Metal Bedplate Profi les.
If unloading and installation require the use of a crane, then the suspension cables must be secured as shown
in the diagram.

How to hoist the unit

THE VENTILATION IS FORMED BY:

1.- Centrifugal fan ( single or double).

2.- Activating motor.

3.- Fixed pulley at the fan.

4.- Adjustable pulley at the motor fan.

5.- transmission pulley or pulleys.

6.- Base of the motor with displacement system for
tensioning of belts.

7.- Tensing screw.

FLOW REGULATION IN THE FANS

The fan in the outdoors units have a variable pulley incorporated into the activating motor, by which it is possible to vary,
when the fan is off its diameter to modify the air fl ow of the unit, as required.

1. Fixed part

2. Mobil part

3. Fixing screw

CLOSE PULLEY:
To increase the fan fl ow, turn the mobile part in
direction “B” (Clock wise).
OPEN PULLEY:
To reduce the fl ow, turn in direction “A”
(Unclock wise).

TENSION OF BELTS

The belts can be easily tensioned through the
tensing screw incorporated into the bases of
the motor of the transmitting units which also
enables a good servicing to be carried out.

When the tensing screw is moved, the motor

2.3.- UNIT LOCATION

- The bedplate is made up of two metal channels, capable of with standing the weight of the units whether hung from the ceiling or
mounted on the fl oor.

- If the unit is fl oor mounted, then the profi les should be isolated with shock absorbing material such as anti-vibration or pads. Keep in
mind that fans rotate at approximately 850 rpm.
For the ones with variable pulley belts, see performances tables.

- The unit is able to work in normal radioelectronic conditions for commercial and residential installations. For any other conditions
please consult.

- If the outside temperature in the area where the heat pump unit is to be installed is low or the cycle functioning are too long, it may
necessary to install an electrical heater, below the likely coils on the drip tray, which avoids the causing of ice in the coil during defrost
cycle.

- If the outdoor unit is going to be installed outside, it is needed to install isolation around the panel of electrical box, to make sure it
became hermetic as well as isolate the electrical panel to avoid condensations. It is also needed to install isolation around the access
panels and seal joints of the casing to make sure the unit became hermetic.

UNIT INSTALLED ON SHOCK ABSORBERS

SERVICE SPACE
Space should be left free for access or servicing, to ease the installation of cables, drainage connections, electric installation and

cleaning fi lters, as well as easy access to the unit.

LOCATION
The unit can be installed outside. If it is installed, air entry and exit ducts should be fi tted. The unit should be assembled on bases
previously made and stood on absorbent and antivibrating material to avoid the vibrations being transmitted to the structure of the
building.

2.6.- DRAINS

All the indoor and outdoor sections of these units have a 3/4” steel threaded drain pipe welded to the condensation tray.

Drainage pipes will be fi tted 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 an inclination of 2% to ease drainage of
condensation.

Mín. 80 mm.

Inspection and cleaning stopper

Also slightly tip the unit (2%) toward the drainage side. Check that the condensation trays are clean and free from dirt and other debris
from the works and that water drains correctly.

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 version.

- Proportional (0-10V).

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

3.1.- PRELIMINARY CHECKS BEFORE FIRST INSTALLATION

- Check that the power supply is the same as stated on the Rating Plate which is in agreement with the electrical
diagram for the unit and that cable sizes are correct.

- Check that tightness of the electrical connections to their terminals and to ground.

- Check the control panel connections.
(If the connection is incorrect, the unit will not operate and the control panel display will not light).

- Check with your hand that the fans are turning freely.

FIGURE FOR THE STANDARD UNIT CONFIGURATION FOR MODELS:

055D-070D-085D

3.- COMMISSIONING AND OPERATION

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.

28

3.- COMMISSIONING AND OPERATION

3.2.- PRELIMINARY CHECKS AT FIRST INSTALLATION

To start the unit, follow the instructions given in the User Manual for the control supplied with the unit
(requiring operation in any of the modes, cooling, heating, or automatic).
After a time delay, the unit will start.
With the unit operating, check that the fans are turning freely and in the correct direction.

CHECK THAT THE COMPRESSOR IS ROTATING IN THE CORRECT DIRECTION.

- If you have the option phase rotation indicator, use it to check the correct rotation.

- If you do not have three phase return lock, check the correct direction of rotation. The suction pressure decreases and the discharge
pressure increases when the compressor is started.

- If the connection is incorrect, rotation will be reversed, causing a high noise level and a reduction in the amount of current consumed.
If this occurs, the compressor’s internal protection system will operate to shut down the unit. The solution is to disconnect, reverse
two of the phases and connect again.

ASTP Protection is included with the unit compressors. See "Fault diagnosis" for more information.

WITH OPERATING UNIT, CHECK:

- Low pressure and high pressure.

- Use the evaporating and liquid temperature to calculate superheat and subcooling.

- Adjust the refrigerant charge and/or expansion valve according to the preceding values.

COMPRESSOR OIL LEVEL
The oil level must always be checked. When the compressor is at rest, the level should be between 1/4 and 3/4
in the sight glass, while when running the level should be between 3/4 and full.
In the event of having to add oil, remember the type of oil is synthetic POE.
The original oil charge in the compressor is ICI Emkarate RL32-3MAF. This type of oil must also be used when replacing the oil
completely.
When only topping up, RL32-3MAF or Mobil EAC Artic 22C can be used.

andregulations and can only be used in a well ventilated area.
Please readcarefully the manufacturer’s instructions before star­ting this unit

All work on the unit must be carried out by a quali• ed and
authorised employee.

Non-compliance with the following instructions may result in in­jury or serious accidents.

Work on the unit:

The unit shall be isolated from the electrical supply by discon­nection and locking using the main isolating switch. Workers
shall wear the appropriate personal protective equipment (hel­met, gloves, glasses,etc.).

Electrical system:

Electrical connections can become loose during transport. Plea­se check them before starting-up the unit Compressors with

specifi c rotation direction. Check the correct rotation direction
of the fan before closing the compressor circuit breakers. If the
direction is incorrect, the phases must be reversed at the head
of the main switch. Work on electric components shall be perfor­med with the power off (see below) by employees having valid
electrical qualifi cation and authorisation.

Refrigerating circuit(s):

After more than 12 hours of power cut, the cranckcase heater
(compressor) should be powered for 5 hours before any return
to service. Non-compliance with this instruction can cause dete­rioration of the compressors.
Monitoring of the pressures, draining and fi lling of the system
under pressure shall be carried out using connections provided
for this purpose and suitable equipment.

To prevent the risk of explosion due to spraying of coolant and
oil, the relevant circuit shall be drained and at zero pres-
sure before any disassembly or unbrazing of the refrigerating
parts takes place.
There is a residual risk of pressure build-up by degassing the
oil or by heating the exchangers after the circuit has been
drained. Zero pressure shall be maintained by venting the
drain connection to the atmosphere on the low pressure side.
The brazing shall be carried out by a qualifi ed brazier. The
brazing shall comply according to code ASME section IX follo­wing the procedures specifi In order to maintain CE marking
compliance, replacement of components shall be carried out
using spare parts, or using parts approved by Lennox.

State of hoses, tightness of screws, earthing, current consumption of the compressor and fans and check
that the unit is receiving the correct voltage.

- COOLING CIRCUIT:

Check that the pressures are correct and that there are no leaks. Check that there is no damage to the

pipe insulation, that the condition of the coils is good and that they are not blocked by bits of paper or
plastic drawn in by the air fl ow, etc.

- COMPRESSOR:

If a sight glass is fi tted, check the oil level.
Check the condition of the silentbloc mountings.

- FANS:

Check that fans turn freely and in the correct direction without excessive noise.

- CONTROL:

Check Set Points and normal operation.

4.2.- CORRECTIVE MAINTENANCE

IMPORTANT

MAKE SURE THAT THE UNIT IS FULLY DISCONNECTED FROM THE POWER SUPPLY WHEN CARRYING OUT

ANY TYPE OF WORK ON THE MACHINE.

If any component in the cooling circuit is to be replaced, follow these recommendations:

- Always use original replacement parts.

- If the component can be isolated, it is not necessary to remove the entire refrigerant charge, if the component cannot be isolating
and the refrigerant charge is removed, it should be removed through the Schrader valves located in the outdoor section. Create a
slight vacuum as a safety measure.

- Regulation prohibits the release of refrigerant into the atmosphere.

- If cuts must be made in the pipe work, use pipe cutters. Do not use saws or any other tools that produce ! lings.

- All brazing must be carried out in a nitrogen atmosphere to prevent corrosion forming.

- Use silver alloy brazing rod.

- Take special care that the " ame from the torch is directed away from the component to be welded and cover with a wet rag to

prevent overheating.

- AIR FILTER :
The air fi lter can be removed through the side by sliding it over the rail or downwards.
(See fi gure).
For downwards removal, remove the two profi les that support it (depending on the model)

which are under the fi lter guide rail and screwed onto the unit.

The fi lter should be cleaned with a vacuum cleaner or washed in soapy water.
The frequency for cleaning or changing the air fi lters 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.

PRECAUTIONS TO BE TAKEN WHEN USING OF R-410A Refrigerant:

R-410A refrigerant is used in the unit; the following standard precautions for this gas should therefore be taken:

- The Vacuum Pump must have a Check Valve or Solenoid Valve fi tted.

- Pressure Gauges and Hoses for exclusive use with R-410A Refrigerant should be used.

- Charging should be carried out in the Liquid Phase.

- Always use scales to weigh-in charge

- Use the Leak Detector exclusive for R-410A Refrigerant.

- Do not use mineral oil, only synthetic oil to ream, expand or make connections.

- Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, fi lings, burrs, etc.).

- When there is a leak, collect what remains of the charge, create a vacuum in the unit and completely recharge with new R­410A Refrigerant.

- Brazing should always be carried out in a nitrogen atmosphere.

- Reamers should always be well sharpened.

- Take very special care if 4-way or check valves are to be replaced since these have internal components that are very heat-sensitive such as
plastic, tefl on, etc.

- If a compressor is to be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing
screws and replace the old compressor with the new one. Check that the new compressor has the correct oil charge, screw it to
the base and connect the lines and electrical connections.

- Evacuate above and below through the Schrader valves of the outdoor unit until -750 mm Hg is reached.

Once this level of vacuum has been reached, keep the pump running for at least one hour.

DO NOT USE THE COMPRESSOR AS A VACUUM PUMP.

- Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are no leaks.

4.2.- CORRECTIVE MAINTENANCE

All the components derived from the recycling of the unit should be managed according local legislation, and have
to be classifi ed and separated while dealt by authorized waste manager or be left in local waste facilities.

Refrigerant fl uids, electronic boards, heat exchangers and the oil extracted from the refrigerant circuit, as well as
the oil recipients used must be recycled as hazardous waste according the local normative through an authorized
waste manager or be left in local waste facilities.

The rest of the components considered as non-hazardous wastes must be recycled according to the corresponding
norms.

At the end of its life, the equipment should be recycled in local waste facilities or by an authorized waste manager.

(three-phase compressor).

- Occasionally, when the compressor stops and starts, there is a metallic noise due to the compressor scrolls. This is
normal.

- Connect high and low pressure gauges and check that the operating pressures are normal.

- Measure electrical consumption for the unit and check that it is close to that indicated on the specifi cation plate.

- Check the electrical consumption of the compressor and the fans against that specifi ed in the physical data sheets.

- In the case of a Heat Pump unit, make a cycle change on the Control Panel, checking that the 4-way valve makes
the change correctly. Check the pressures in the new cycle.

- CL60: Low pressure switch and high pressure switch are reset automatically and if it operates 3 times in one

day, they change to manual reset, through the control unit.

ASTP COMPRESSOR PROTECTION:

This device protects the compressor against high discharge temperatures.
When the temperature reaches critical values, ASTP protection causes

the "Scrolls" to separate. The compressor stops pumping but the motor
continues to run.
