OPERATING CHECKS:
IMPORTANT INFORMATION REGARDING THE
REFRIGERANT USED:
•
This product contains fluorinated greenhouse gas
covered by the Kyoto protocol.
•
Fluid type: R134a
•
Global Warming Potential (GWP): 1430
CAUTION:
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 gas recovery for recycling, regeneration or
destruction is at customer charge.
7. Periodic leak tests have to be carried out by the
customer or by third parties. The EU regulation set the
periodicity here after

No requirement
* From 01/01/2017, units must be equipped with a leakage detection system
8. 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.
9. Contact your local dealer or installer if you have any
questions.
Information on operating inspections given in EN 378
standard can be used when similar criteria do not exist in the
national regulation.
PROTECTION DEVICE CHECKS:
•
If no national regulations exist, check the protection
devices on site in accordance with standard EN 378:
once a year for the high-pressure switches, every five
years for external relief valves.
The company or organisation that conducts a pressure switch
test must 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 Carrier Service for this type of test. Carrier mentions
here only the principle of a test without removing the
pressure switch:
- Verify and 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 pressure gauge protected against pulsations
(filled with oil with maximum pointer if mechanical),
preferably calibrated (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).
CAUTION: If the test leads to replacing the pressure switch,
it is necessary to recover the refrigerant charge, these pressure
switches are not installed on automatic valves (Schraeder
type).
At least once a year, visually inspect the protection devices
(valves, pressure switches).
If the machine operates in a corrosive environment, inspect
the protection devices more frequently.
Check regularly for leaks and repair immediately. Ensure
regularly that the vibration levels remain acceptable and
close to those at the initial unit start-up.
After an equipment failure, carry out a refrigerant analysis
at a specialist laboratory. If required, change the refrigerant
following a procedure such as that described in NF E29-795.
If the refrigerant circuit remains open after an intervention
(such as a component replacement, etc.):
• Seal the openings if the duration is less than a day
• If more than 1 day, charge the circuit with oxygen free
nitrogen (inertia principle).
The objective is to prevent penetration of atmospheric
humidity and the resulting corrosion.
