• Never operate the air conditioner without the filters in place.

• Do not use the air conditioner near a bathtub, shower, washbasin, or other wet areas.

• Do not use means to accelerate the defrosting process or to clean other than those recommended by the manufacturer.

• The appliance shall be stored in a room without continuously operating ignition sources (for example open flames, an operating gas appliance, or an operating electric heater. Do not pierce or burn.

• Be aware that refrigerants may not contain an odor.

  • the maximum refrigerant charge amount is 11.46oz.

• The appliance shall be stored to prevent mechanical damage from occurring.

• Any person who is involved with working on or breaking into a refrigerant circuit should hold a currently valid certificate from an industry-accredited assessment authority, which authorizes their competence to handle refrigerants safely in accordance with an industry recognized assessment specification. Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repairs requiring the assistance of other skilled personnel shall be carried out under the supervision of a person competent in the use of flammable refrigerants.

• Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. The work shall be undertaken under a controlled procedure to minimize the risk of flammable gas or vapor being present while the work is being performed. 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 the control of flammable material.

• The area shall be checked with an appropriate refrigerant 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. no sparking, adequately sealed, or intrinsically safe.

• If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO² fire extinguisher adjacent to the charging area.

• Anyone carrying out work in relation to a refrigeration 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 sufficiently far away from the site of installation, repair, removal and disposal, during which flammable refrigerant can possibly be released into 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.

• 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.

• 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 living in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

• Check that the 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.

• Under no circumstances shall potential sources of ignition be used in the search for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.

• 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 after 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 should 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 or 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.

• 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 practices is followed since flammability 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 must be recovered and placed in the appropriate recovery cylinders. The system shall be
  “flushed” 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 fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is present in the system. When the final OFN charge is used, the system must be vented down to atmospheric pressure in order for work to be performed. 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.

• 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 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 overfill the refrigeration system.

• The system must be pressure tested with OFN before it can be charged. The system shall be leak tested upon completion of charging but prior to commissioning. Before leaving the site, a follow up leak test must be performed.

• Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details. It is recommended as good practice that all refrigerants be recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to the re-use of reclaimed refrigerant. It is critical that electrical power be available before beginning the task.

  • 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 it´s 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 overfill 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 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.
  • k) 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 must be signed and be date-tamped. Ensure that there are labels on the equipment stating that it contains flammable refrigerant.

• When removing refrigerant from a system, either for servicing or decommissioning, it is recommended as good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Check that the correct number of cylinders are available to hold the total system charge. All the 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 a 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 have 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 must 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 the 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 shall be 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 must be carried out safely.

DRAIN THE INTERNAL WATER

This portable air conditioner has two drain ports, higher one and lower one and we can use two drainage methods: manual drainage and continuous drainage.

1. Manual Drain
   This unit is designed with a highly efficient self-evaporative system, and It is suggested to use manual drainage in cooling mode, all condensate will be recycled in the unit to ensure enough water to recycle in the unit to cool condenser and enhance cooling performance advance; however in extreme humidity, water tank at chassis will be full, “FL” will show on the LED display, it will need to be drained manually from lower drain port.

2. Put the tray below the water outlet at the back of the unit.

3. Screw off the drain cover; unplug the water stopper for water flow into the tray.

4. Plug in stopper and screw the water cover tightly onto water outlet after drainage.
   Notes:

5. Move the unit carefully to avoid the leakage if it is necessary.

6. Protect the drain cover and water stopper properly.

7. Tilt the unit slightly backwards when draining.

8. Block the drain hole as soon as possible before the tray is full if it can’t hold all water in the unit to prevent the water leakage and wet the floor or carpet.

9. Water stopper and drain cover must be tightly installed, to avoid new condensate to wet the floor or carpet when the unit re-starts working.

10. Continuous drain: (strongly recommend using this method and draining from lower drain port under heating mode, because the self-evaporative cooling system doesn’t work under heating mode)

11. Screw off the drain cover

12. Connect drain-hole with φ13mm PVC drain hose, as deep as possible to avoid leakage (as Photo 16).

13. Pull the drain hose to bathroom or outdoor.
    Notes：

  * Drain hose must be installed before unit starts working.
  * It is suggested to use manual drainage when unit in cooling mode, to ensure enough water to recycle in the unit to cool condenser and enhance cooling performance.
  * Put the drain hose in an inaccessible place, not higher than drainage hole and keep the drain hose straight without any flexure.
  * Keep the drain cover and its stopper properly installed when continuous drainage is adopted.![air-choice-NPE8-08C-X1E-12000-BTU-Portable-Air-Conditioner- \(21\)](https://manuals.plus/wp-content/uploads/2023/11/air-choice-NPE8-08C-X1E-12000-BTU-Portable-Air-Conditioner-21.png)
