Disposal Label - Ariston 801 Instructions For Installation, Use, Maintenance

DISPOSAL (for authorised personnel)
WARNING!
THE WATER HEATER IS SUPPLIED WITH 0.15 KG OF R290 REFRIG-
ERANT.
THE R290 REFRIGERANT (PROPANE) IS A FLAMMABLE AND
ODOURLESS REFRIGERANT.
THE REFRIGERANT RECOVERY OPERATIONS MAY ONLY BE CAR-
RIED OUT BY QUALIFIED PERSONNEL WITH THE APPROPRIATE
PERSONNEL CERTIFICATION CERTIFYING THEIR KNOWLEDGE
OF AND ABILITY TO MANAGE PLANTS CONTAINING HC-TYPE
GASES SUCH AS R290 (PROPANE), AND WITH ADEQUATE
EQUIPMENT.
Before carrying out this procedure, it is essential that the technician
is completely familiar with the equipment and all its detail. It is rec-
ommended good practice that all refrigerants are recovered safely.
Prior to the task being carried out, an oil and refrigerant sample shall
be taken in case analysis is required prior to re-use of recovered
refrigerant. It is essential that electrical power is available before the
task is commenced.
The following procedure should be performed:
- Become familiar with the equipment and its operation.
- Isolate system electrically.
- Before attempting the procedure, ensure that:
- Mechanical handling equipment is available, if required, for han-
dling refrigerant cylinders.
- All personal protective equipment is available and being used cor-
rectly.
- The recovery process is supervised at all times by a competent
person.
- Recovery equipment and cylinders conform to the appropriate
standards.
- Pump down refrigerant system, if possible.
- If a vacuum is not possible, make a manifold so that refrigerant can
be removed from various parts of the system.
- Make sure that cylinder is situated on the scales before recovery
takes place.
- Start the recovery machine and operate in accordance with in-
structions.
- Do not overfill cylinders (no more than 80 % volume liquid charge).
- Do not exceed the maximum working pressure of the cylinder,
even temporarily.

DISPOSAL LABEL

Equipment shall be labelled stating that it has been de-commissioned
and emptied of refrigerant. The label shall be dated and signed. For
appliances containing flammable refrigerants, ensure that there are
labels on the equipment stating the equipment contains flammable
refrigerant.
RECOVERING THE REFRIGERANT GAS
When removing refrigerant from a system, either for servicing or de-
commissioning, it is recommended good practice that all refrigerants
are removed safely.
When transferring refrigerant into cylinders, ensure that only appro-
priate refrigerant recovery cylinders are employed. Ensure that the
correct number of cylinders for holding the total system charge is
available. All cylinders to be used are designated for the recovered
refrigerant and labelled for that refrigerant (i.e. special cylinders for
the recovery of refrigerant). Cylinders shall be complete with pres-
sure-relief valve and associated shut-off valves in good working or-
der. Empty recovery cylinders are evacuated and, if possible, cooled
before recovery occurs.
The recovery equipment shall be in good working order with a set
of instructions concerning the equipment that is at hand and shall
be suitable for the recovery of all appropriate refrigerants including,
when applicable, flammable refrigerants. In addition, a set of cali-
brated weighing scales shall be available and in good working order.
Hoses shall be complete with leak-free disconnect couplings and in
good condition.
Before using the recovery machine, check that it is in satisfactory
working order, has been properly maintained and that
any associated electrical components are sealed to prevent ignition
in the event of a refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant suppli-
er in the correct recovery cylinder, and the relevant waste transfer
note arranged. Do not mix refrigerants in recovery units and espe-
cially not in cylinders.
If compressors or compressor oils are to be removed, ensure that
they have been evacuated to an acceptable level to make certain
that flammable refrigerant does not remain within the lubricant.
The evacuation process shall be carried out prior to returning the
compressor to the suppliers. Only electric heating to the compres-
sor body shall be employed to accelerate this process. When oil is
drained from a system, it shall be carried out safely.
INFORMATION AND PERSONNEL TRAINING
The training should include the substance of the following:
- Information about the explosion potential of flammable refriger-
ants to show that flammables may be dangerous when handled
without care.
- Information about potential ignition sources, especially those that
are not obvious, such as lighters, light switches, vacuum cleaners,
electric heaters.
Information about the different safety concepts:
- Safety of the appliance does not depend on ventilation of the
housing. Switching off the appliance or opening of the housing
has no significant effect on the safety. Nevertheless, it is possi-
ble that leaking refrigerant may accumulate inside the enclosure
and flammable atmosphere will be released when the enclosure
is opened.
Information about refrigerant detectors:
- Principle of function, including influences on the operation.
- Procedures, how to repair, check or replace a refrigerant detector
or parts of it in a safe way.
- Procedures, how to disable a refrigerant detector in case of repair
work on the refrigerant carrying parts.
Information about the concept of sealed components and sealed
enclosures according to IEC 60079-15:2010.
Information about the correct working procedures:
a) Commissioning
- Ensure that the floor area is sufficient for the refrigerant charge
or that the ventilation duct is assembled in a correct manner.
- Connect the pipes and carry out a leak test before charging with
refrigerant.
- Check safety equipment before putting into service.
b) Maintenance
- Portable equipment shall be repaired outside or in a workshop
specially equipped for servicing units with flammable refriger-
ants.
- Ensure sufficient ventilation at the repair place.
- Be aware that malfunction of the equipment may be caused by
refrigerant loss and a refrigerant leak is possible.
- Discharge capacitors in a way that won't cause any spark. The
standard procedure to short circuit the capacitor terminals usu-
ally creates sparks.
- Reassemble sealed enclosures accurately. If seals are worn, re-
place them.
- Check safety equipment before putting into service.
c) Repair
- Portable equipment shall be repaired outside or in a workshop
specially equipped for servicing units with flammable refriger-
ants.
- Ensure sufficient ventilation at the repair place.
- Be aware that malfunction of the equipment may be caused by
refrigerant loss and a refrigerant leak is possible.
- Discharge capacitors in a way that won't cause any spark.
