1. Any intervention on the refrigerant circuit of this
product should be performed in accordance
with the applicable legislation. In the EU, the
regulation is called F-Gas, N°517/2014.
2. Ensure that the refrigerant is never released to
the atmosphere during installation, maintenance
or equipment disposal.
3. The deliberate gas release into the atmosphere
is not allowed.
4. If a refrigerant leak is detected, ensure that it is
stopped and repaired as quickly as possible.
5. Only a qualified and certified personnel can
perform installation operations, maintenance,
refrigerant circuit leak test as well as the
equipment disposal and the refrigerant
recovering.
6. The recovery of gas for recycling, regeneration
or destruction is paid for by the customer.
Periodic leak tests must be carried out by the
customer or by third parties. The EU regulation
set the periodicity here after

7. A logbook must be established for equipments
subject to periodic leak tests. It should contain
the quantity and the type of fluid present within
the installation (added and recovered), the
quantity of recycled fluid, regenerated or
destroyed, the date and output of the leak test,
the designation of the operator and its belonging
company, etc.
8. Contact your local dealer or installer if you have
any questions.
The information on operating inspections given in annex C
of standard EN378 can be used if no similar criteria exist in
the national regulations.
Protection device checks:
-
If no national regulations exist, check the protection
devices on site in accordance with standard EN378: once
a year for the high-pressure switches, every five years
for external safety valves.
-
The detailed description of the high-pressure switch test
method is given in the service manual for the unit.
The company or organisation that conducts a pressure switch
test shall establish and implement a detailed procedure to fix:
• Safety measures
• Measuring equipment calibration
• Validating operation of protective devices
• Test protocols
• Recommissioning of the equipment.
Consult your nearest service office for this type of test. Here is
mentions only the principle of a test without removing the
pressure switch:
- Verify and record the set-points of pressure switches and relief
devices (valves and possible rupture discs)
- Be ready to switch-off the main disconnect switch of the power
supply if the pressure switch does not trigger (avoid over-
pressure or excess gas in case of valves on the high-pressure
side with the recovery condensers)
- Connect a calibrated pressure gauge (the values displayed
on the user interface may be inaccurate in an instant reading
because of the scanning delay applied in the control)
- Complete an HP Test as provided by the software (refer to
the Control IOM for details).
At least once a year thoroughly inspect the protection
devices (valves, pressure switches). If the machine operates
in a corrosive environment, inspect the protection devices
more frequently.
Regularly carry out leak tests and immediately repair any
leaks.
1.4 - Repair safety considerations
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. After each repair of the unit, check the
operation of the protection devices and create a report of the
parameter operation at 100%.
Comply with the regulations and recommendations in unit and
HVAC installation safety standards, such as: EN 378, ISO 5149,
etc.
If a leak occurs or if the refrigerant becomes polluted (e.g. by a
short circuit in a motor or BPHE frost) remove the complete
charge using a recovery unit and store the refrigerant in mobile
containers.
Repair the leak detected and recharge the circuit with the total
R-410A charge, as indicated on the unit name plate. Do not top
up the refrigerant charge. Only charge liquid refrigerant R-410A
at the liquid line.
Ensure that you are using the correct refrigerant type before
recharging the unit.
Charging any refrigerant other than the original charge type
(R-410A) will impair machine operation and can even destroy
the compressors. The compressors operating with this
refrigerant type are lubricated with a synthetic polyolester oil.
Before any intervention on the refrigerant circuit the
complete refrigerant charge needs to be recovered.
On LGN units with remote condenser, the installer must
clearly note the total amount of refrigerant used by the
system (in kg) on the label affixed to the unit.
RISK OF EXPLOSION: Never use air or a gas containing
oxygen during leak tests to purge lines or to pressurise a
machine. Pressurised air mixtures or gases containing
oxygen can be the cause of an explosion. Oxygen reacts
violently with oil and grease.
Only use dry nitrogen for leak tests, possibly with an
appropriate tracer gas.
Failure to observe the above recommendations can have
serious or even fatal consequences and damage installations.
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.
