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
voltage (< 50 Volt). The service panels can only be opened using tools.

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.
