6. Information on servicing
i Checks to the area
Prior to beginning work on systems containing ammable refrigerants, safety checks are necessary to ensure that
the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied
with prior to conducting work on the system.
ii Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a ammable gas or vapour
being present while the work is being performed.
iii General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried
out. Work in conned spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that
the conditions within the area have been made safe by control of ammable material.
iv Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the
technician is aware of potentially ammable atmospheres. Ensure that the leak detection equipment being used is
suitable for use with ammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
v Presence of re extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate re
extinguishing equipment shall be available to hand. Have a dry powder or CO2 re extinguisher adjacent to the
charging area.
vi No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that
contains or has contained ammable refrigerant shall use any sources of ignition in such a manner that it may lead
to the risk of re or explosion. All possible ignition sources, including cigarette smoking, should be kept sufciently
far away from the site of installation, repairing, removing and disposal, during which ammable refrigerant can
possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be
surveyed to make sure that there are no ammable hazards or ignition risks. No Smoking signs shall be displayed.
vii Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or
conducting any hot work. A degree of ventilation shall continue during the period that the work is carried
out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the
atmosphere.

viii Checks to the refrigeration equipment
Where electrical components are being changed, they shall be t for the purpose and to the correct
specication. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt
consult the manufacturer’s technical department for assistance. The following checks shall be applied to
installations using ammable refrigerants:
The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
The ventilation machinery and outlets are operating adequately and are not obstructed;
If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of
refrigerant; Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall
be corrected;
Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any
substance which may corrode refrigerant containing components, unless the components are constructed of
materials which are inherently resistant to being corroded or are suitably protected against being so corroded.
viiii Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection
procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the
circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to
continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the
equipment so all parties are advised.
Initial safety checks shall include:
That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; That there no
live electrical components and wiring are exposed while charging, recovering or purging the system; That there is
continuity of earth bonding.
7. Repairs to sealed components
i During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being
worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply
to equipment during servicing, then a permanently operating form of leak detection shall be located at the most
critical point to warn of a potentially hazardous situation.
ii Particular attention shall be paid to the following to ensure that by working on electrical components, the casing
is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive
number of connections, terminals not made to original specication, damage to seals, incorrect tting of glands,
etc. Ensure that apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such
that they no longer serve the purpose of preventing the ingress of ammable atmospheres. Replacement parts
shall be in accordance with the manufacturer’s specications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated prior to working on them.
8. Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not
exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe components are
the only types that can be worked on while live in the presence of a ammable atmosphere. The test apparatus
shall be at the correct rating. Replace components only with parts specied by the manufacturer. Other parts
may result in the ignition of refrigerant in the atmosphere from a leak.
9. Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other
adverse environmental effects. The check shall also take into account the effects of aging or continual vibration
from sources such as compressors or fans.

10. Detection of ammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant
leaks. A halide torch (or any other detector using a naked ame) shall not be used.
11. Leak detection methods
The following leak detection methods are deemed acceptable for systems containing ammable refrigerants.
Electronic leak detectors shall be used to detect ammable refrigerants, but the sensitivity may not be adequate,
or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the
detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment
shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed
and the appropriate percentage of gas (25 %maximum) is conrmed. Leak detection uids are suitable for use
with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react
with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked ames shall be removed/
extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered
from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen
free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
12. Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall
be used. However, it is important that best practice is followed since ammability is a consideration. The following
procedure shall be adhered to:
Remove refrigerant; Purge the circuit with inert gas; Evacuate; Purge again with inert gas; Open the circuit by
cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be ushed with
OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen
shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and
continuing to ll until the working pressure is achieved, then venting to atmosphere, and nally pulling down to
a vacuum. This process shall be repeated until no refrigerant is within the system. When the nal OFN charge
is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation
is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum
pump is not close to any ignition sources and there is ventilation available.
13. Charging procedures
In addition to conventional charging procedures, the following requirements shall be followed. Ensure that
contamination of different 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 refrigeration 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 overll the refrigeration system. Prior to recharging the system it shall be
pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning.
A follow up leak test shall be carried out prior to leaving the site.
14. Decommissioning
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 reclaimed
refrigerant. It is essential that electrical power is available before the task is commenced.

a) Become familiar with the equipment and its operation. b) Isolate system electrically. c) Before attempting
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. 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 instructions. h) Do not overll cylinders. (No more than 80 % volume liquid charge). i) Do
not exceed the maximum working pressure of thecylinder, even temporarily. j) When the cylinders have been
lled 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. k) Recovered refrigerant shall not be
charged into another refrigeration system unless it has been cleaned and checked.
15. Labelling
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall
be dated and signed. Ensure that there are labels on the equipment stating the equipment contains ammable
refrigerant.
16. Recovery
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
labelled 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 ammable
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.
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 ammable 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 compressor body shall
be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Because of a new federal test procedure for Portable Air Conditioners, you may notice that the cooling capacity claims
on portable air conditioner packaging are signicantly lower than that of models produced prior to 2017. This is due to
changes in the test procedure, not to the portable air conditioners themselves.
What should I look for first when purchasing a portable air conditioner?
The right air conditioner helps you cool a room efciently. An undersized unit won’t cool adequately while one that’s too
large will not remove enough humidity, leaving the air feeling damp. To nd the proper air conditioner, determine the
square footage of the room you want to cool by multiplying the room length by its width. You also need to know the air
conditioner’s BTU (British Thermal Unit) rating, which indicates the amount of heat it can remove from a room. A higher
number means more cooling power for a larger room. (Be sure you are comparing only newer models to each other-
older models may appear to have a higher capacity, but are actually the same). Be sure to “size up” if your portable air
conditioner will be placed in a very sunny room, in a kitchen, or in a room with high ceilings. After you’ve found the right
cooling capacity or your room, you can look at other features.
Why is the cooling capacity lower on newer models than on older units?
Federal regulations require manufacturers to calculate cooling capacity based on a specic test procedure, which was
changed just this year. Models manufactured before 2017 were tested under a different procedure and cooling capacity
is measured differently than in prior years’models. So, while the BTUs may be lower, the actual cooling capacity of the air
conditioners has not changed.
What is SACC ?
SACC is the representative value of Seasonally Adjusted Cooling Capacity, in Btu/h, as determined in accordance with
the DOE test procedure at title 10 Code of Federal Regulations (CFR) 430, subpart B, appendix CC and applicable
sampling plans.
