SAFETY
The safety information contained in this manual is provided as a guide for the safe handling of this
installation. LENNOX does not vouch for the completeness of this information and can therefore not
accept liability for any possible omissions. In the roof tops, heat is being transported by a pressurized
refrigerant, with changes in pressure and temperature. For air cooled roof tops, fans have been provided
to discharge heat into the environment. The protection of operating and maintenance personnel was
central in the design of the roof top. Safety features have been included to prevent excessive pressure
in the system. Sheet metal parts have been fitted to prevent inadvertent contact with (hot) pipes. For
air cooled roof tops, the fans are equipped with protective grids and the electrical control panel is
completely touch-proof. This excludes some parts operating at a safe voltage (< 24 Volt). The service
panels can only be opened using tools.
The electrical control panel is completely touch-proof. This excludes some parts operating at a safe

INTRODUCTION
Notwithstanding that the units are equipped with extensive safety and protection features, the
utmost care and attention is needed when carrying out operations on the machine. Furthermore,
ear protection should be worn when working on or in the vicinity of the roof tops. Operations on the
cooling circuit or electrical equipment should be carried out by authorized personnel.
It is essential to follow non exhaustive recommendations hereunder:
Never work on a unit that is still energized. Wait 15 minutes before working on the machine after a
power outage (discharge of the capacitors).
Any manipulation (opening or closing) of a shut-off valve must be carried out by a qualified and
authorized engineer. These procedures must be carried out with the unit shut-down.
• Never work on any of the electrical components, until the general power supply to the unit
has been cut. During any maintenance operations on the unit, lock the power supply circuit
in the open position ahead of the machine. If the work is interrupted, check the lock before
resuming the work.
• WARNING: Even if the unit has been switched off, the power circuit remains energized, unless
the unit or circuit disconnect switch is open. Refer to the wiring diagram for further details.
• In case of maintenance operations on fans (grills replacement …) ensure that the power is
shut off to avoid automatic restart.
• Before the opening of the refrigerant circuit, check the pressure with manometers or pressure
sensors, and purge the circuit.
• Never leave a unit stopped with valves closed on the liquid line, refrigerant could be trapped
and the pressure would rise.
• All installation parts must be maintained by the personnel in charge, in order to avoid
material deterioration and injuries to people. Faults and leaks must be repaired immediately.
The authorized technician must have the responsibility to repair the fault immediately. Each
time repairs have been carried out to the unit, the operation of the safety devices must be
re-checked.
• Follow guidance and recommendations given in safety and machine standards such as EN378,
ISO5149, etc.
• Do not use oxygen to purge lines or to pressurize a machine for any purpose. Oxygen gas
reacts violently with oil, grease, and other common substances.
• Never exceed the specified maximum operating pressures.
• Verify the allowable maximum high- and low-side test pressures by checking the instructions
in this manual and the pressures given on the unit name plate.
• Do not use air for leak testing. Use only nidron or dry nitrogen.
• Do not unweld or flame cut the refrigerant lines or any refrigerant circuit component until
all refrigerant (liquid and vapor) has been removed from roof top. Traces of vapor should be
displaced with dry air nitrogen. Refrigerant in contact with an open flame produces toxic
gases.
• Do not siphon refrigerant
• Avoid spilling liquid refrigerant on skin or splashing it into the eyes. Use safety goggles. Wash
any spills from the skin with soap and water. If liquid refrigerant enters the eyes, immediately
and abundantly flush the eyes with water and consult a doctor

INTRODUCTION
• Attention: The high-pressure safety switches are essential elements which guarantee the
system remains within the admissible operating limits. Before switching on the installation,
always ensure all electrical connections are correct on these elements which are used to
isolate the electrical power supply to the compressor(s) they protect. Carry out a test to
ensure the electrical power supply is effectively isolated when the pressure switch attains
its set value.
• In case of installation in a seismic zone or in a zone which may be effected by violent
natural occurrences such as storms, tornados, floods, tidal waves, etc.…, the installer and/
or operator will refer to valid standards and regulations in order to ensure the devices
required are available as our units are not designed to operate under such conditions
without prior precautions.
• The equipment is not designed to resist fire. The installation site will therefore have to
respect valid standards with regard to protection against fire (emergency instructions,
map…).
• In case of exposure to corrosive external atmospheres or products, the installer and/or
operator shall take the necessary precautions to avoid damage to the equipment and
will make sure the equipment provided has the necessary and sufficient anti-corrosion
protection.
• To respect a sufficient number of supports for the piping according to their size and
weight under operating conditions and to design the piping to avoid a water hammer
phenomenon
• For technical reasons, it is not possible to carry out hydrostatic tests on all our units so
leak tests are carried out as a compensatory measure. (The entire circuit is checked using
leak detectors). For machines charged with refrigerant, at the end of the test, an HP test
is carried out in the factory to make sure the pressure switch is working properly.
• Before any work is carried out on the refrigeration circuit, the dry air or nitrogen pressure
our units are supplied with must be released (For units not charged with refrigerant in the
factory.)
• The emissions of refrigerant via the safety relief valves must be channeled to the exterior
of the machine room. The outlet relief valve will have to be sized in compliance with
EN13136.
• Installation and maintenance of these machines must be carried out by personnel qualified
to work on refrigeration equipment.
• All interventions must be carried out in conformity with valid safety regulations (e. g.: EN
378), as well as the recommendations indicated on the labels and handbooks provided
with the machine. All actions shall be taken to avoid access of unauthorized persons.
• It is essential that any pipework or other components of the refrigeration circuit hazardous
to people because of their surface temperature are insulated or identified.
• Ensure that the installation zone (room or area) of the machine has restricted access and
ensure the good condition of the covering.

5.2. SAFETY STANDARDS
THE MANUFACTURER DECLINES ALL LIABILITY FOR THE FAILURE TO OBSERVE THE
FOLLOWING SAFETY STANDARDS.
IT FURTHERMORE DECLINES ALL LIABILITY FOR DAMAGE CAUSED BY THE IMPROPER USE OF
THE UNIT AND/OR MODIFICATIONS MADE WITHOUT AUTHORISATION.
INSTALLATION MUST BE PERFORMED BY SPECIALIST PERSONNEL.
• During installation, always wear suitable safety clothing, for example: glasses, gloves, etc., as
described in the EC 686/89 and following standards.
• During installation, all work must be performed in complete safety, in an environment that is
clean and free of obstacles.
• Always observe the laws in force in the country where the unit is installed relating to the use
and disposal of the packaging and the products used for the cleaning and maintenance of the
unit, as well as the recommendations of the manufacturer of such products.
• Before starting the unit, check that the various components and the entire system are in
perfect order.
• Never touch or stand between the moving parts.
NEVER START ANY MAINTENANCE OR CLEANING WORK UNTIL THE POWER SUPPLY HAS
BEEN DISCONNECTED.

• When decommissioning the unit, observe the legislation in force relating to the prevention
of pollution.
N.B. When operating the unit, the installer and user must consider and prevent all other types of
risk relating to the system. For example, risks deriving from the introduction of foreign matter, or
alternatively risks due to the intake of dangerous flammable or toxic gases at high temperature
5.3. SELECTING THE SITE OF INSTALLATION
• Make sure that the support surface is able to support the weight of the unit(units) and will
not cause vibrations.
• Make sure that the support surface is perfectly horizontal so as to allow the correct coupling
of the various sections, if necessary, making up the unit.
• Make sure the unit is level, using, if necessary, spacers below the supports, so as to ensure
that the doors open correctly and the pans are drained.
• Never position the unit in rooms where there are flammable gases or acidic, aggressive or
corrosive substances that may irreparably damage the various components.
• Leave a minimum amount of free space around the unit, as shown in the figure, so as to allow
for installation, maintenance and the replacement of components, such as coils, filters etc.
• If the unit is hung from the ceiling, given the weights involved, all the sections that make up
the air handling unit must be connected to the ceiling.
As the motor-fan assembly and the moving parts feature vibration dampers and are dynamically
insulated from the structure by the vibration dampers on the base and the flexible joint on the outlet,
external vibration dampers are not required.
If, for technical-structural requirements, vibration damping supports are installed between the unit
and the support base, elastic joints must also be used on the water fittings (coils, humidifier, drains,
etc.) and on the air fittings (air outlets, fan openings, etc.).
5.4. JOINING THE SECTIONS
A special slide-in joint acts as a guide for coupling the various sections together, and ensures perfect
seal when assembly is complete.
AS MENTIONED IN PAR. 1.1, THE MATERIALS REQUIRED FOR ASSEMBLY ARE ALL SENT INSIDE
THE VENTILATING SECTION
• To assemble the sections making up the unit, proceed as follows:
• Make sure that the support surface is level.
• Apply a bead of silicon, supplied, around the entire perimeter of the joint.
• Bring the sections together, using the slide-in joint as a reference.
• Fasten the self-threading screws, supplied, into the holes provided. These must be screwed in
from inside the unit, through the inspection doors or by removing the panels adjacent to the
joint, according to the dimensions or the configuration of the unit.

5.5 CONNECTIONS TO THE DUCTS
IMPORTANT: THE UNITS MUST NEVER BE OPERATED IF THE FAN OUTLETS ARE NOT DUCTED
OR PROTECTED BY SAFETY MESH, AS PER THE UNI 9219 AND FOLLOWING STANDARDS.
• The ducts must be sized according to the ratings of the system and the characteristics of
the fans. Incorrect calculation of the size of the ducting may lead to a drop or an increase in
output, causing the activation of any safety devices in the system.
• To prevent the formation of condensate and attenuate the level of noise, insulated ducts
should be used.
• Electrical continuity between the duct and the unit must be guaranteed by an earth wire.
5.6. WATER CONNECTIONS
The installation and connection of the pipes are operations that may compromise the correct operation
of the system, or worse, cause irreversible damage to the unit. These operations must be performed
by specialist person.
5.6.1. COIL WATER CONNECTIONS
The units are supplied with coils with threaded “male” fittings. Upon request, flanged fittings can be
supplied.
THE WATER INLET AND OUTLET MUST BE FITTED SO AS TO ALLOW COUNTER-CURRENT
HEAT EXCHANGE BETWEEN THE AIR AND THE FLUID (WATER OR WATER AND ANTI-FREEZE
MIXTURE), WITH THE INLET AT THE BOTTOM AND THE OUTLET AT THE TOP. FOR THIS REASON,
APPROVAL IS ALWAYS REQUIRED OF THE CONSTRUCTIONAL DRAWINGS THAT HIGHLIGHT
THE SIDE OF THE FITTINGS. MOREOVER, THE UNITS ARE FITTED WITH SPECIAL PLATES THAT
INDICATE THE WATER INLET AND OUTLET.
• The direct expansion coils have welded fittings.
• The connections should be tightened with care taken to avoid damage.
• The path of the pipes must be designed so as not to create obstacles when removing the coil
or the filter from the unit and to guarantee access to the inspection doors.
• Suitably support the pipes outside of the unit to avoid loading the weight of these onto the
coil.
• When the pipes have been connected, push the external rubber gasket firmly against the
panel, to avoid air leaks.
• The insulation must touch against the panel, to avoid the risk of burns / condensation.
• Install on-off valves to isolate the coil from the rest of the circuit in the event of special
maintenance.
• In the case of installation in particularly cold areas, if the use of an electric anti-freeze device
or the addition of anti-freeze (glycol) to the water are not envisaged, empty the system when
it remains inactive for extended periods.
• Remove, where envisaged, the fastening bolts for transport so as to restore the play required
to guarantee the expansion of the pipes
WARNING: ALWAYS USE TWO SPANNERS WHEN TIGHTENING THE COIL FITTINGS TO THE
PIPES, SO AS TO AVOID STRESS (TORSION, THRUST) THAT MAY DAMAGE THE MANIFOLDS
INSIDE THE UNIT.

5.6.2. DISCHARGE CONNECTIONS
Connect the discharges from each condensate
collection pan to the sewerage system either
directly or via the manifold.
• On each pan with discharge, fit a
drain trap of suitable height so as to
prevent air entering into the system by
depression, and stopping the correct
drainage of the water. A correct drain
trap also prevents the infiltration of bad
odours.
• The sizing and the construction of
the drain trap must comply with the
following formula: H >= P, where P,
expressed in mm w.c., is equal to the
pressure gain of the unit installed.
• The drain trap must be fitted with a bleeding cap at the lowest point, and must be made so
as to allow quick dismantling for more complete cleaning.
• The path of the condensate drain pipe must always slope down towards the outside.
• Check that the condensate drain pipe does not stress the discharge fitting on the unit.
5.7. ELECTRICAL CONNECTIONS
BEFORE STARTING ANY OPERATIONS, MAKE SURE THAT THE MAIN POWER LINE IS
DISCONNECTED.
• The electrical connections must be performed by specialist personnel.
• Check that the voltage and frequency shown on the unit’s rating plate match the mains
power supply.
CONNECT THE UNIT AND ALL ITS ACCESSORIES USING LES WITH A SUITABLE CROSS-
SECTION FOR THE POWER RATINGS AND IN COMPLIANCE WITH THE LOCAL STANDARDS IN
FORCE. THE SIZE OF THE CABLES MUST IN ANY CASE GUARANTEE A VOLTAGE DROP WHEN
STARTING OF LESS THAN 3% OF THE RATED VALUE.
• Never use adapters, multiple sockets and/or extensions in the main power supply to the unit.
THE INSTALLER MUST ENSURE THAT A POWER DISCONNECTING SWITCH AND ANY OTHER
DEVICES THAT PROTECT THE ELECTRICAL PARTS ARE INSTALLED AS NEAR AS POSSIBLE TO
THE UNIT.
• All the ventilating sections are fitted with door lock safety micro- switches; the connections
to the micro-switch must be made by the installer. The micro-switch disconnects power to
the motor when opening the inspection door.
CAUTION: WAIT 60 SECONDS BEFORE APPROACHING AND ENTERING THE VENTILATING
SECTION, SO AS TO ALLOW THE VENTILATING ASSEMBLY TO COME TO A COMPLETE STOP.
• Connect the unit to an effective earth wire.
6.0. CHECK BEFORE STARTING
Before starting, the air handling unit should undergo the following checks.
1. Check that the discharges are properly connected, ensuring the correct draining of the
condensate.
