1)Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of
ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting
work on the system.
2)Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while
the work is being performed.
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 sectioned off. Ensure that the conditions within
the area have been made safe by control of flammable material.
4)Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerating detector prior to and during work to ensure the technician is aware of
potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable
refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
5)Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing
equipment shall be available. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
6)No ignition sources
No person carrying out work in relation to a refrigerating system which involves exposing any pipe work that contains or has
contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion.
All possible ignition sources, including cigarette smoking, should be kept far away from the site of installation, 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 ignition risks. No Smoking signs shall be displayed.
7)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.
8)Checks to the refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. 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 flammable refrigerants:
-The actual refrigerant charge is in accordance with the room size where 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;
6.Information on servicing
09
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.
9.Cabling
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 flame) shall not be used. The following leak detection methods are deemed acceptable
for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable 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 confirmed.
Leak detection 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/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. Removal of refrigerant shall be
according to Removal and Evacuation.
10.Detection of flammable refrigerants
When breaking into the refrigerant circuit to make repairs – or for any other purpose–conventional procedures shall be used.
However, for flammable refrigerants it is important that best practices be followed, since flammability is a consideration. The
following procedure shall be adhered to:
a) Safely remove refrigerant following local and national regulations.
b) Evacuate.
11.Removal and evacuation
7.Sealed electrical components shall be replaced
8.Intrinsically safe components must be replaced
-Refrigerating 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.
9)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.
10
c) Purge the circuit with inert gas. (optional for A2L)
d) Evacuate. (optional for A2L)
e) Continuously flush or purge with inert gas when using flame to open circuit.
f) Open the circuit.
The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes.
For appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance
safe for flammable refrigerants. This process might need to be repeated several times.
Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants,
refrigerant purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until
the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This
process shall be repeated until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen charge
is used, the system shall be vented down to atmospheric pressure to enable work to take place. Ensure that the outlet for the
vacuum pump is not close to any potential ignition sources and that ventilation is available.
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 minimize the amount of refrigerant contained in them
• Cylinders shall be kept in an appropriate position according to the instructions.
• 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 overfill the refrigeration system.
• Prior to recharging the system it shall be pressure tested with nitrogen.
• 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.
12.Charging procedures
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.
• Become familiar with the equipment and its operation.
• Isolate the system electrically.
• 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.
13.Decommissioning
11
• Pump down the 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 instructions.
• Do not overfill cylinders. (No more than 80 % volume liquid charge).
• Do not exceed the maximum working pressure of the cylinder, even temporarily.
• 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.
• Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
Equipment shall be labeled 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 flammable refrigerant.
14.Labeling
• 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 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. 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 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.
• Non-duct connected appliances containing A2L refrigerants with the supply and return air openings in the conditioned space may
have the body of the appliance installed in open areas such as false ceilings not being used as return air plenums, as long as the
conditioned air does not directly communicate with the air of the false ceiling.

This Exhaust Control allows the air
conditioner to either circulate inside
air (Closed) or exhaust air to the
outside (Open).
The Closed position is used when
maximum cooling is desired. It may
also be used for air recirculation
without cooling when the air
conditioner is set in any FAN
position.
The Open position removes stale air
from the room and exhausts it to the
outside. Fresh air is drawn in through
normal passages in the home.
To choose operating mode, press
Mode button. Each time you press
the button, a mode is selected in a
sequence that goes from Auto, Cool,
Dry and Fan.

thereof, regardless of any defects in the Product or any part or component thereof.
B. LIMITED EXTENDED WARRANTY THROUGH PRODUCT REGISTRATION: If and only if the Original Customer registers the
Product at www.elementelectronics.com within ninety (90) days of the date of purchase by the Original Customer, then the Warranty Period
discussed in subpart 1.A. above shall be extended an additional one (1) year to a new Warranty Period equaling two (2) years from the date of
purchase by the Original Customer. If the Product is not registered as provided for in this subpart 1.B, then the standard one-year Warranty
Period set forth in subpart 1.A shall apply.
C. TIMING AND PROCEDURE: Before Warranty service can commence, the Original Customer must contact either (i) the retailer
from whom the Original Customer purchased the Product, or (ii) Element directly, in either case for problem determination and service
procedures. Valid Proof of Purchase evidencing that the Product is within the Warranty Period MUST be presented by Original Customer in
order to obtain the requested Warranty service. Please have your model and serial number available, along with your date of purchase of the
Product. To remain eligible for Warranty service, Original Customer may not return the Product or any part or component thereof to the retailer
or Element without Element’s prior written consent.
2. EXCLUSIONS AND LIMITATIONS TO WARRANTY SERVICE
The Warranty covers manufacturing defects in materials and workmanship of the Product encountered in the normal, non-commercial use of
the Product, and does not cover (a) damages or malfunctions resulting from improper or unreasonable use or maintenance, abuse, negligence,
failure to follow instructions contained in any written materials that accompany the Product, deterioration by reason of excess moisture,
corrosive atmosphere, lightning, power surges, connections to improper voltage supply, unauthorized alteration, or other external causes such
as extremes in temperature or humidity, modifications, scratches or discoloration; (b) any damage caused by using non-authorized parts or
service facilities for repair of Products (however, for avoidance of doubt, using non-authorized parts or service facilities will not, in and of itself,
void the Warranty); (c) transportation, shipping, delivery, pickup, insurance, installation, or set-up costs; (d) ordinary wear and tear, cosmetic
damage, or damage due to acts of nature, including but not limited to, water, floods, wind, storm, tornado, earthquake, or fire, or due to
damage caused by extraordinary impact events, such as dropping, crushing, demolition or other extraordinary damage; (e) commercial use of
the Product, or use of the Product for anything other than single-family household or residential use; or (f) modification of the Product or any
part of the Product.
This Warranty is made to the Original Customer only and does not cover Products sold AS IS or WITH ALL FAULTS. The Warranty is invalid if the
factory-applied serial number has been altered or removed from the Product. This Warranty is valid only in the United States, and only applies
to Product if it was purchased and serviced in the United States. The addition of equipment or features to the Product that are not
manufactured or recommended by Element could affect the intended function of the Product, and therefore may void the Warranty.
Furthermore, the exposure of the Product to chemicals, heat, cold, humidity, or other elements can affect the Product components, and
therefore, the Warranty does not cover discoloration, fading, cosmetic changes, rust, or any damages or failure related to any such items. The
Warranty is contingent upon the proper use, maintenance, and care of the Product. The Warranty may be void if the Product has been used in
a manner contradictory to, or in violation of, the terms of the user’s manual, warnings, or instructions accompanying the Product.
THIS WARRANTY IS MADE IN LIEU OF AND SUPERSEDES ALL OTHER WARRANTIES OR CONDITIONS OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE OR GENERAL USE, WHETHER EXPRESS, IMPLIED, COLLATERAL, STATUTORY, OR PROVIDED BY COMMON LAW, THE
UNIFORM COMMERCIAL CODE, OR OTHERWISE. ELEMENT FURTHER DISCLAIMS ALL WARRANTIES AFTER THE END OF THE WARRANTY TERM
DEFINED ABOVE. NO OTHER EXPRESS WARRANTY OR GUARANTY GIVEN BY ANY OTHER PERSON, FIRM, OR ENTITY WITH RESPECT TO THE
PRODUCT SHALL BE BINDING ON ELEMENT. REPAIR, REPLACEMENT, OR REFUND OF THE ORIGINAL PURCHASE PRICE, AT ELEMENT’S SOLE
DISCRETION, ARE THE EXCLUSIVE REMEDIES OF THE CUSTOMER.
ELEMENT SHALL NOT BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES CAUSED BY THE USE, MISUSE, OR INABILITY TO USE
THE PRODUCT. THESE INCLUDE, BUT ARE NOT LIMITED TO, ANY DAMAGES IN THE FORM OF LOST PROFITS, LOSS OF USE, LEGAL FEES,
ECONOMIC LOSS, PERSONAL INJURIES, OR ANY OTHER DAMAGES CAUSED BY CIRCUMSTANCES BEYOND THE CONTROL OF ELEMENT.
NOTWITHSTANDING THE FOREGOING, ELEMENT’S AGGREGATE LIABILITY TO ANY CUSTOMER SHALL NOT EXCEED THE ORIGINAL PURCHASE
PRICE OF THE PRODUCT. THIS WARRANTY SHALL NOT EXTEND TO ANYONE OTHER THAN THE ORIGINAL CUSTOMER WHO PURCHASED THE
PRODUCT, AND IS NOT TRANSFERRABLE. NO PERSON IS AUTHORIZED TO ALTER, EXTEND, OR WAIVE THIS WARRANTY OR ANY OF ITS TERMS
OR CONDITIONS.
Some states do not allow the exclusion or limitation of incidental or consequential damages, or allow limitations on warranties, so the above
limitations or exclusions may not apply to you. This Warranty gives you specific rights, and you may have other rights, which vary from state to
state. The exclusions and limitations to the Warranty apply to the maximum extent permitted by law and unless restricted or prohibited by
law. Where any term of this Warranty is prohibited by applicable law, it shall be null and void, but the remainder of this Warranty shall remain
in effect.
