The recovery equipment shall be in good working order with a set of instruc

ti

ons concerning the equipment that is at

hand and shall be suitable for the recovery of

ammable refrigerants. In addi

ti

on, 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 condi

ti

on. Before using the recovery machine, check that it is in sa

ti

sfactory working order, has been properly

maintained and that any associated electrical components are sealed to prevent igni

ti

on in the event of a refrigerant

release. Consult manufacturer if in doubt.

The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the
relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially 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

fla

mmable refrigerant does not remain within the lubricant. The evacua

ti

on process shall be

carried out prior to returning the compressor to the suppliers. Only electric hea

ti

ng to the compressor body shall be

employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

DECOMMISSIONING

Before carrying out this procedure, it is essen

tia

l that the technician is completely familiar with the equipment and

all its detail. It is recommended good prac

ti

ce 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 reclaimed
refrigerant. It is essen

ti

al that electrical power is available before the task is commenced.

a) Become familiar with the equipment and its opera

ti

on.

b) Isolate system electrically.
c)

Before a

tt

emp

ti

ng the procedure ensure that:

-

Mechanical handling equipment is available, if required, for handling refrigerant cylinders;

-

All personal protec

ti

ve equipment is available and being used correctly;

-

The recovery process is always supervised by a competent person;

-

Recovery equipment and cylinders conform to the appropriate standards.

d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the

system.

f)

Make sure that cylinder is situated on the scales before recovery takes place.

g) Start the recovery machine and operate in accordance with manufacturer's instruc

ti

ons.

h) Do not ove

rfil

l cylinders. (No more than 80 % volume liquid charge).

i)

Do not exceed the maximum working pressure of the cylinder, even temporarily.

j)

When the cylinders have been

fill

ed correctly and the process completed, make sure that the cylinders and the

equipment are removed from site promptly and all isola

ti

on valves on the equipment are closed o

.

k) Recovered refrigerant shall not be charged into another refrigera

ti

on system unless it has been cleaned and

checked.

CHARGING PROCEDURES

In addi

ti

on to conven

ti

onal charging procedures, the following requirements shall be followed.

-

Ensure that contamina

ti

on of d

iff

erent refrigerants does not occur when using charging equipment. Hoses or

lines shall be as short as possible to minimise the amount of refrigerant contained in them.

-

Cylinders shall be kept upright.

-

Ensure that the refrigera

ti

on system is earthed prior to charging the system with refrigerant.

-

Label the system when charging is complete (if not already).

-

Extreme care shall be taken not to ove

rfil

l the refrigera

ti

on system.

Prior to recharging the system, it shall be pressure tested with OFN. The system shall be leak tested on comple

ti

on of

charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

The safety wire model is 5*20_5A/250VAC, and must meet the explosion-proof requirements.
