Decommissioning Procedure; Recovery Requirements And Guidelines - Cornelius VIPER E 2 FLAVOR Manual

Viper Installation, Service & Decommissioning Manual
Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and
all its detail. It is recommended 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 procedure is commenced.

Decommissioning Procedure

1) Become familiar with the equipment and its operation.
2) Isolate the system electrically by disconnecting all AC power sources.
3) Before beginning the procedure, ensure that:
Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
All personal protective equipment is available and being used correctly;
The recovery process is supervised at all times by a competent person;
Recovery equipment and cylinders conform to the appropriate standards.
4) Pump down the refrigerant system, if possible. NOTE: If a vacuum is not possible, make a manifold so that refrigerant can
be removed from various parts of the system.
!
CAUTION:
Do not overfill cylinders (no more than 80% volume liquid charge).
Do not exceed the maximum working pressure of the cylinder, even temporarily.
!
CAUTION:
When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the
equipment are removed from site promptly and all isolation valves on the equipment are closed off.
!
CAUTION:
Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and
checked.
!
CAUTION:
DO NOT switch recovery system on/off near the source of flammable refrigerant that may be leaking out or may leak out
during recovery-system line connection/disconnection.

Recovery Requirements and Guidelines

When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that
all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate 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 labeled for that refrigerant (i.e. special cylinders for the recovery of
refrigerant). Cylinders shall be complete with pressure-relief valve and associated shut-off valves in good working order.
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
calibrated 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.
