7)Venlated area
Ensure that the area is in the open or that it is adequately venlated before breaking into the system or
conducng any hot work. A degree of venlaon shall connue during the period that the work is carried
out. The venlaon should safely disperse any released refrigerant and preferably expel it externally into
the atmosphere.
Repair and maintenance to electrical components shall include inial safety checks and component
inspecon procedures. If a fault exists that could compromise safety, then no electrical supply shall be
connected to the circuit unl it is sasfactorily dealt with. If the fault cannot be corrected immediately
8)Checks to the refrigeraon equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct
specificaon. At all mes 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 installaons using flammable refrigerants:
The charge size is in accordance with the room size within which the refrigerant containing parts are
installed;
The venlaon machinery and outlets are operang adequately and are not obstructed;
If an indirect refrigerang circuit is being used, the secondary circuit shall be checked for the presence
of refrigerant; Marking to the equipment connues to be visible and legible. Markings and signs that
are illegible shall be corrected;
Refrigeraon pipe or components are installed in a posion where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless the components are co
nstructed of materials which are inherently resistant to being corroded or are suitably protected against
being so corroded.
9)Checks to electrical devices
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure
the technician is aware of potenally flammable atmospheres. Ensure that the leak detecon
equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately
sealed or intrinsically safe.
5)Presence of fire exnguisher
If any hot work is to be conducted on the refrigeraon equipment or any associated parts, appropriate
fire exnguishing equipment shall be available to hand. Have a dry powder or CO2 fire exnguisher
adjacent to the charging area.
6)No ignion sources
No person carrying out work in relaon to a refrigeraon system which involves exposing any pipe
work that contains or has contained flammable refrigerant shall use any sources of ignion in such a
manner that it may lead to the risk of fire or explosion. All possible ignion sources, including cigaree
smoking, should be kept sufficiently far away from the site of installaon, repairing, removing and
disposal, during which flammable 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
flammable hazards or ignion risks. No Smoking signs shall be displayed.
3)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 confined spaces shall be avoided. The area around the workspace shall
be seconed off. Ensure that the condions within the area have been made safe by control of
flammable material.
4)Checking for presence of refrigerant
Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable
gas or vapour being present while the work is being performed.
Safety Precautions
Page 6 

Do not apply any permanent inducve or capacitance loads to the circuit without ensuring that this will
not exceed the permissible voltage and current permied for the equipment in use. Intrinsically safe
components are the only types that can be worked on while live in the presence of a flammable
atmosphere. The test apparatus shall be at the correct rang. Replace components only with parts
specified by the manufacturer. Other parts may result in the ignion of refrigerant in the atmosphere
from a leak.
8.Repair to intrinsically safe components
and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 %
maximum) is confirmed. Leak detecon fluids 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 flames shall be removed/ exnguished.
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.
10.Detection of flammable refrigerants
The following leak detecon methods are deemed acceptable for systems containing flammable
refrigerants. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensivity
may not be adequate, or may need re-calibraon. (Detecon equipment shall be calibrated in a
refrigerant-free area.) Ensure that the detector is not a potenal source of ignion and is suitable for
the refrigerant used. Leak detecon equipment shall be set at a percentage of the LFL of the refrigerant
11.Leak detection methods
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibraon, sharp edges or
any other adverse environmental effects. The check shall also take into account the effects of aging or
connual vibraon from sources such as compressors or fans.
9.Cabling
Under no circumstances shall potenal sources of ignion be used in the searching for or detecon of
refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.
7.Repairs to sealed components
1)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 operang form of leak detecon
shall be located at the most crical point to warn of a potenally hazardous situaon.
2)Parcular aenon 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 protecon is affected. This shall include damage
to cables, excessive number of connecons, terminals not made to original specificaon, damage to
seals, incorrect fing 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 prevenng the
ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer's
specificaons.
NOTE: The use of silicon sealant may inhibit the effecveness of some types of leak detecon equipment.
Intrinsically safe components do not have to be isolated prior to working on them.
but it is necessary to connue operaon, an adequate temporary soluon shall be used. This shall be
reported to the owner of the equipment so all pares are advised.
Inial 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 connuity of earth bonding.

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 filled correctly and the
process completed, make sure that the cylinders and the equipment are removed from site promptly
and all isolaon valves on the equipment are closed off.k) Recovered refrigerant shall not be charged
into another refrigeraon system unless it has been cleaned and checked.
15.Labelling
Equipment shall be labelled stang that it has been de-commissioned and emped of refrigerant. The
label shall be dated and signed. Ensure that there are labels on the equipment stang the equipment
contains flammable refrigerant.
Before carrying out this procedure, it is essenal that the technician is completely familiar with the
equipment and all its detail. It is recommended good prac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al that electrical power is available before
the task is commenced.
14.Decommissioning
a) Become familiar with the equipment and its operaon.b) Isolate system electrically.c) Before
aempng the procedure ensure that: Mechanical handling equipment is available, if required, for
handling refrigerant cylinders;All personal protecve equipment is available and being used correctly;
The recovery process is supervised at all mes 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ons.h) Do not overfill
13.Charging procedures
In addion to convenonal charging procedures, the following requirements shall be followed. Ensure
that contaminaon 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 refrigera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 overfill the refrigeraon system. Prior to recharging the system it
shall be pressure tested with OFN. The system shall be leak tested on compleon of charging but prior
to commissioning. A follow up leak test shall be carried out prior to leaving the site.
12.Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for any other purpose convenonal
procedures shall be used. However, it is important that best pracce is followed since flammability is
a consideraon. 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 cung or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be flu-
shed with OFN to render the unit safe. This process may need to be repeated several mes. Comp-
ressed air or
oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system with OFN and connuing to fill unl
the working pressure is achieved, then venng to atmosphere, and finally pulling down to a vacuum.
This process shall be repeated unl no refrigerant is within the system. When the final OFN charge is
used, the system shall be vented down to atmospheric pressure to enable work to take place. This
operaon is absolutely vital if brazing operaons on the pipe-work are to take place.
Ensure that the outlet for the vacuum pump is not close to any ignion sources and there is venla-
on available.

16.Recovery
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended
good pracce that all refrigerants are removed safely. When transferring refrigerant into cylinders, en-
sure 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 refr-
igerant). 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 instrucons concerning the

a set of calibrated weighing scales shall be available and in good working order. Hoses shall be com-
plete with leak-free disconnect couplings and in good condion. Before using the recovery machine,
check that it is in sasfactory working order, has been properly maintained and that any associated
electrical components are sealed to prevent igni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 flammable refrig-
erant does not remain within the lubricant. The evacuaon process shall be carried out prior to ret-
urning the compressor to the suppliers. Only electric heang to the compressor body shall be empl-
oyed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
Operation of Current Device
The power supply cord contains a current measuring device
that detects damage to the power cord. Test your power
supply cord as follows:
1. Plug in the air condioner.
2. The power supply cord will have TWO buons on the
plug head. Press the TEST buon. You will noce a click as
the RESET buon pops out.
3. Press the RESET Buon. You will noce a click as the
buon engages.
4. The power supply cord is now supplying electricity to
the unit. (On some products this is also indicated by a light
on the plug head.)
NOTICE
The power supply cord with this air condioner contains
a current detecon device designed to reduce the risk of
fire.
In the event that the power supply cord is damaged, it
can not be repaired. It must be replaced with a cord from

Mobile air condioner with combined exhaust hose need the Exhuast Adaptor to test the condenser
inlet and outlet airflows. The Exhuast Adaptor must be provided by the manufacturer. The Exhuast
Adaptor connect the condenser inlet and outlet airflows to the airflow measuring instrument in
laboratory.
Because of a new federal test procedure for Portable Air Condioners, you may noce that the
cooling capacity claims on portable air condioner packaging are significantly lower than that of
models produced prior to 2017. This is due to changes in the test procedure, not to the portable
air condioners themselves.
What should I look for first when purchasing a portable air condioner?
The right air condioner helps you cool a room efficiently. An undersized unit won't cool adequately
while one that's too large will not remove enough humidity, leaving the air feeling damp. To find
the proper air condioner, determine the square footage of the room you want to cool by
mulplying the room length by its width. You also need to know the air condioner's BTU (Brish
Thermal Unit) rang, which indicates the amount of heat it can remove from a room. A higher
Why is the cooling capacity lower on newer models than on older units?
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 condioner will be placed in a very sunny room, in a
kitchen, or in a room with high ceilings. Aer you’ve found the right cooling capacity or your
room, you can look at other features.
Federal regulaons require manufacturers to calculate cooling capacity based on a specific 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 condioners has not changed.
What is SACC ?
SACC is the representave value of Seasonally Adjusted Cooling Capacity, in Btu/h, as determined
in accordance with the DOE test procedure at tle 10 Code of Federal Regulaons (CFR) 430,
subpart B, appendix CC and applicable sampling plans.
NOTICE
The appearance of your unit might be slightly different.
