Carrier AquaForce PUREtec 30XAV-ZE 401 Installation, Operation And Maintenance Instructions page 7

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.
OPERATING CHECKS:
IMPORTANT INFORMATION REGARDING THE
REFRIGERANT USED:
• This product contains fluorinated greenhouse gas
covered by the Kyoto protocol.
• Fluid type: R1234ze(E)
• Global Warming Potential (GWP): 1
CAUTION:
1. Any handling of refrigerant contained in this product
must comply with the F-Gas Directive N° 517/2014
and any other applicable local legislation.
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
strictly 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. The customer has to carry out periodic leak tests In
the European Union, article 2 of regulation (EU)
No. 517/2014 makes these mandatory and sets their
frequency. The table below shows this frequency, as
originally published in the regulation. Check whether
an inspection frequency is also set by other
regulations or standards applicable to your system
(e.g. EN 378, ISO5149, etc.).

• A logbook must be established for the systems that
require a tightness check. It should contain the
quantity and the type of fluid present within the
installation (added and recovered), the quantity
of recycled fluid/regenerated/destroyed, the date
and output of the leak test, the designation of the
operator and its belonging company, etc.
• Contact your local dealer or installer if you have any
questions.
