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.
Everyone involved in the product life cycle must perform a risk analysis. This applies to manufacturers, installers, maintainers
and end-users. If risks are not eliminated or remain at unacceptable levels of occurrence or severity, they must be
communicated to the next party (the customer in general) through the drafting of an installation, use, maintenance guide.
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. The service panels can only be opened using tools by
authorized personnel.
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. All 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 an electrical component 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 in accordance with current environmental directives.
•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. The use of
the EN 378-2 standard provides you with the state of the art with regard to the essential safety requirements of the
Machine Directives and PED.
•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. Successive purges with a neutral gas (such as dry nitrogen) are recommended to remove
all traces of refrigerant. Refrigerant in contact with an open flame produces toxic gases.
•Do not siphon refrigerant
•Wearing PPE is mandatory (glasses, cuffs, gloves, masks). Avoid splashing refrigerant on the skin or in the eyes. 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
e-BALTIC-IOM-2020.12-EN 7
PED DIRECTIVE
For units covered by the Pressure Equipment Directive (see EU Declaration of Conformity).
Warning:
1. 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. Carry out a test to ensure the electrical power supply is effectively turned off when the pressure switch
attains its set value.
2. 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.
3. The equipment is not designed to resist fire. The installation site will therefore have to respect valid standards about
protection against fire (emergency instructions, map…).
4. 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.
5. 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
6. For technical reasons, it is not possible to carry out hydrostatic tests on all our units. Our rooftops are hermetically
sealed products according to the definition of the F-Gas directive and certain local regulations such as CH35 in France.
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
7. 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.)
8. If a valve is fitted, the emissions of refrigerant via the safety relief valves must be directed to the outside, to a place free
of ignition sources, fresh air intake and human presence.. The valve should be sized and connected in compliance with
current standards.
9. Installation and maintenance of these machines must be carried out by personnel qualified to work on refrigeration
equipment.
10. 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.
11. 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.
12. Ensure that the installation zone (room or area) of the machine has restricted access and ensure the good condition of
the covering.

SAFETY AREA
The product is hermetically sealed and bears the CE mark. As such, it is for France exempted from the measures described in
§ 3 of CH35 in the context of normal operation.
A formalized periodic inspection of the product's hermeticity will guarantee the preservation of this high level of hermeticity.
Nevertheless, in abnormal operating conditions, leaks may occur (poor maintenance, maintenance with opening of the
refrigeration circuit). For these cases, prior to placing these products on the market, we carried out studies in accordance with
standards EN 60079-10-1 and EN 378. Thus the rooftop installed according to our recommendations and well maintained does
not generate an ATEX zone.
Moreover, the product is equipped with safety devices against the risk of flammability. (see § On-board safety with R32 gas).
Please maintain the detection system and the associated control chain according to EN 60079-29-1 and EN 50495. In case of
maintenance we recommend that the operators be equipped with an explosimeter, switch off the power supply to the rooftop
and do not approach any potential source of ignition without first checking the absence of a potentially flammable area due to
an undetected leak.
The end user should update the DUER (Document Unique d'Evaluation des Risques) indicating the presence on his site of
products charged with R32 fluid, and train his personnel on the good practices to be adopted for a safe use.
For particular uses or installations that do not comply with the assumptions of clearance rate calculations according to EN
60079-10-1 (see above), please contact us if you need information to perform your own ATEX zoning calculation.
INSTALLATION ON A FLAMMABLE GAS UNIT
ATEX : It is forbidden to store and install the machine in an ATEX area.
In the immediate area of the Rooftop (proximity distance ≤ to 2m):
-The presence, even temporary, of ignition sources is prohibited (electrical or heat sources see EN 378),
-It is forbidden to install fresh air vents in the building or in extracts
For ducting/ducted units, ensure that no sources of ignition as defined by EN378 (e.g. electrical and heat) are installed in or
near the ducts.
Minimum building volume:
For a given volume of building to be ventilated, the standard gives a maximum load per circuit in flammable fluid A2L/A2/A3.
According to the standard, for R32 fluid, Lennox recommends a maximum load per circuit of :
If the mass of refrigerant is between 1.8 and 12kg :
m ≤ √A x h x 0.571
If the mass of refrigerant is between 12 and 60kg :
m ≤ A x h x 0.061
m: mass of refrigerant A2L (kg)
A : area of the room (in m²)
h : air supply height in the room (in m) (max: 2.2)

POWERING UP A UNIT CONTAINING FLAMMABLE GAS
Before switching on the power supply, please carry out a refrigerant leak detection using an appropriate device to ensure that
there is no refrigerant around the machine.
ELECTRIC WIRING ON A UNIT CONTAINING FLAMMABLE GAS
When a cable passes through a wall, be sure to use a cable gland to ensure that the cable is sealed and insulated. This insulation
prevents any electric arcs that could ignite the refrigerant if leaked.
INTERVENTION ON A UNIT CONTAINING FLAMMABLE GAS
Before any intervention on a machine with A2L / A2 / A3 flammable fluid, carry out a leak detection using an appropriate device
to ensure that there is no refrigerant around the machine.
When working on a machine with flammable fluid A2L/A2/A3, do not cause sources of flammability in the area near the rooftop
(see above). For example: do not smoke, make phone calls, do not use walkie-talkies.
CORRECTIVE MAINTENANCE ON R32 GAS UNIT:
The following precautions, specific to this gas, must be taken when using the R32 refrigerant:
•The vacuum pump must be fitted with a non-return valve or a solenoid valve and comply with R32 (A2L).
•Pressure gauges and pipes suitable for refrigerant R32 must be used.
•Use only pipe cutters and no torches to open the pipes.
•The load must be applied in the liquid phase.
•Always use a scale to charge the refrigerant.
•Use the leak detector suitable for R32 refrigerant.
•Do not use mineral oil, only synthetic oil for boring, expanding or making connections.
•Keep the pipes closed before using them and pay close attention to any traces of humidity and dirt (dust, filings,
burrs, etc.).
•Brazing must always be carried out in a nitrogen atmosphere.
•The drill bits must always be sharp.
•The refrigerant bottle must contain at least 2% of the total amount.
WARNING
Care must be taken to remove refrigerant from the system before cutting or unbrazing any piping with a tool suitable for
use with R32 (A2L).
We recommend the following protocol before any piping work:
•Drain the unit with the appropriate drain device for R32 (A2L).
•Charge the unit with dry nitrogen to allow any remaining R32 in the oil to be removed.
•Repeat these operations twice
•Release the pressure in a recovery cylinder and in accordance with the F-gas directive (R32 is an HFC listed in annex
1 of the F-gas directive).

ON-BOARD SAFETY ON R32 GAS UNIT:
A2L Rooftop units are supplied with leak detectors. They are connected to a NO/NC contact, provided to the customer, which
closes in case of a major leak.
FIRE AND SMOKE SAFETY HAVE PRIORITY OVER LEAK DETECTION.
The R32 detector is composed of a gas sensor on ventilation side and a control board. The control board is only intended for
indoor application. Do not change the position of the sensor elements.
The sensitive layer of the sensors reacts chemically in the presence of R32, changing its conductivity. The different oxidation
processes modify the conductivity and therefore the measurement, which is why regular calibrations are necessary. Regular
maintenance must be carried out in accordance with the instructions. Do not generate electrostatic discharges.
The following are currently known to poison the sensor and change its sensitivity:
•Polymerizing substances such as ethylene oxide, acrylonitrile, butadiene, styrene, silicone.
•Catalytic poisons, such as Sulphur and phosphorus compounds, silicon compounds, metallic vapors.
•Organic solvents
