SAFETY CODES & REGULATIONS
THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH LOCAL SAFETY CODES AND REGULATIONS AND CAN ONLY BE
USED IN WELL VENTILLATED AREA.
PLEASE READ CAREFULLY THE MANUFACTURER’S INSTRUCTIONS BEFORE STARTING THIS UNIT.
INSPECTIONS AND REQUALIFICATION ACCORDING PRESSURE EQUIPMENT DIRECTIVE MUST FOLLOW THE LOCAL
REGULATIONS WHERE THE UNIT IS INSTALLED.
EMC DIRECTIVE COMPLIANCE
WARNING:
The units FLATAIR ADVANCED 2 range are designed to heat or cool buildings in industrial, commercial and residential environ-
ments. What di󰀨erentiates these environments is the position of the HT / LV transformer in the power supply to the buildings. In
the case of the industrial environment, the HT / LV transformer is dedicated and installed in the industry itself. On the other hand,
for the residential, commercial and light industry, the HT / LV transformer is common to a zone and supplies both commercial, light
industrial buildings and houses (individual houses and buildings) in parallel.
So to meet all of these environments, the units have been tested according to the most stringent standards of the 2 environments
that are:
• EN61000-6-3: emission for residential, commercial and light industry environments:
• EN61000-6-2: immunity for industrial environment.
As regards immunity, all the tests carried out were in conformity.
As regards emissions:
• Meets the EN61000-6-3 (emission for residential, commercial and light industry environments)
• The short-circuit ratio Rsce > 350 corresponding to the standard EN 61000-3-12 concerning the measurement of harmonics
on the network.
• No maximum permissible impedance of the network Zmax is necessary to declare from standard EN 61000-3-11 because
the equipments tested are in conformity with the standard. The connection to the main is not a conditional connection (the
connection is possible to all the mains without restriction on the impedance value).
All units are compliant with the PED directive.
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 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 e󰀨ectively isolated when the pressure switch attains its set value.
2. In case of installation in a seismic zone or in a zone which may be e󰀨ected by violent natural occurrences such as
storms, tornados, oods, 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 re. The installation site will therefore have to respect valid standards with
regard to protection against re (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 neces-
sary and su󰀩cient anti-corrosion protection.
5. To respect a su󰀩cient number of supports for the piping according to their size and weight under operating condi-
tions 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 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.
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. 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.
9. Installation and maintenance of these machines must be carried out by personnel qualied to work on refrigeration
equipment.
10. All interventions must be carried out in conformity with valid safety regulations (e. g.: NF 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 ot
her components of the refrigeration circuit hazardous to people because of their surface temperature are insulated or
identied.
12. Ensure that the installation zone (room or area) of the machine has restricted access and ensure the good condi-
tion of the covering.

SAFETY
It is essential to follow non exhaustive recommendations hereunder:
• Never work on a unit that is still energized.
• Anymanipulation (opening or closing) of a shut-o󰀨 valvemust be carried out by a qualied and authorised engineer.These proce-
dures 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 o󰀨, the power circuit remains energized, unless the unit or circuit disconnect
switch is open. Refer to the wiring diagram for further details.
• For some units, a separate 220V power supply may exist, check the electrical wiring for more information’s
• In case of maintenance operations on fans (grills replacement …) ensure that the power is shut o󰀨 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 immedia-
tely. 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 specied 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 refrigerant or dry nitrogen.
• Do not unweld or ame cut the refrigerant lines or any refrigerant circuit component until all refrigerant (liquid and vapour) has
been removed from rooftop. Traces of vapour should be displaced with dry air nitrogen. Refrigerant in contact with an open ame
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 ush the eyes with water and consult a doctor.
