POWERCIAT LX ST/HE/XE
These pipes must be installed in a way that ensures that
people and property are not exposed to refrigerant leaks.
As the fluids can be diffused in the air, ensure that the outlet
is far away from any building air intake, or that they are
discharged in a quantity that is appropriate for a suitably
absorbing environment.
Periodic check of the relief valves: See chapter 1.3
“Maintenance safety considerations”.
Provide a drain in the drain pipe, close to each relief valve,
to avoid an accumulation of condensate or rain water.
All precautions concerning handling of refrigerant must be
observed in accordance with local regulations.
Ensure good ventilation, as accumulation of refrigerant in
an enclosed space can displace oxygen and cause
asphyxiation or explosions.
Inhalation of high concentrations of vapour is harmful and
may cause heart irregularities, unconsciousness, or death.
Vapour is heavier than air and reduces the amount of oxygen
available for breathing. These products cause eye and skin
irritation. Decomposition products are hazardous.
1.2 - Equipment and components under
pressure
These products incorporate pressure equipment or components.
We recommend that you consult your appropriate national trade
association or the owner of the equipment or components under
pressure (declaration, re-qualification, retesting, etc.).
The characteristics of this equipment/these components are
given on the nameplate or in the required documentation,
supplied with the products.
These units are intended to be stored and operated in an
environment where the ambient temperature must be not less
than the lowest allowable temperature indicated on the
nameplate.
Do not introduce significant static or dynamic pressure with
regard to the operating pressures used during operation or for
tests in the refrigerant circuit or in the heat exchange circuits.
See section 11.2 - “Pressure vessels”.
1.3 - Maintenance safety considerations
CIAT recommends using the following maintenance logbook

nor does it invoke the manufacturer's liability):

(1) Maintenance, repairs, regular verifications (EN 378), leakage, etc.
Engineers working on the electric or refrigeration components
must be authorized, trained and fully qualified to do so.
All refrigerant circuit repairs must be carried out by a trained
person, fully qualified to work on these units. He must have been
trained and be familiar with the equipment and the installation.
All welding operations must be carried out by qualified specialists.
Any manipulation (opening or closing) of a shut-off valve must
be carried out by a qualified and authorised engineer. These
procedures must be carried out with the unit shut-down.
NOTE: The unit must never be left shut down with the liquid
line valve closed, as liquid refrigerant can be trapped
between this valve and the expansion device and lead to
the risk of a pressure increase. This valve is situated on the
liquid line before the filter drier box.
During any handling, maintenance and service operations
the engineers working on the unit must be equipped with
safety gloves, glasses, shoes and protective clothing.
Never work on a unit that is still energized.
Never work on any of the electrical components, until the
general power supply to the unit has been cut using the
disconnect switch(es) in the control box(es).
If any maintenance operations are carried out on the unit,
lock the power supply circuit in the open position ahead of
the machine.
If the work is interrupted, always ensure that all circuits are
still deenergised before resuming the work.
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. Attach appropriate safety
labels.
Units with the Power Factor Correction option are equipped
with capacitor batteries with a discharge time of five (5)
minutes after disconnecting the power. After disconnecting
the power to the control box, wait five minutes before
opening the control box. Before any intervention, verify that
there is no voltage present at any accessible conducting
parts of the power circuit.
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
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 qualified and certified personnel can
perform installation and maintenance work, run
the refrigerant circuit leak tests, prepare the
equipment for disposal, and recover the
refrigerant.
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:
