WARNING

The following applies to R-32 refrigerant systems.

  • 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.

  • Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapours 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 control of flammable material.

  • Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-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.

  • No person 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, 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.

  • 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.

  • 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:
    1. the charge size is in accordance with the room size within which the refrigerant containing parts are installed;
    2. the ventilation machinery and outlets are operating adequately and are not obstructed;
    3. if an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant; 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.

  • Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures.

  • Initial safety checks shall include:
    1. that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
    2. that no live electrical components and wiring are exposed while charging, recovering or purging the system;
    3. that there is continuity of earth bonding.

  • 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.

  • 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 specification, damage to seals, incorrect fitting of glands, etc.

  • Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres.

  • Replacement parts shall be in accordance with the manufacturer’s specifications.

  • 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 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 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 ageing or continual vibration from
    sources such as compressors or fans.

  • 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 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 shall be recovered into the correct 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 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 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.

  • 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.

  • Prior to recharging the system it shall be pressure tested with OFN.

  • DD.12 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.

  1. Become familiar with the equipment and its operation.

  2. Isolate system electrically.

  3. 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.

  4. Pump down refrigerant system, if possible.

  5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

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

  7. Start the recovery machine and operate in accordance with manufacturer’s instructions.

  8. Do not overfill cylinders. (No more than 80 % volume liquid charge).

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

  10. 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.

  11. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

  • This process shall be repeated until 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 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.
  • 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.
  • Prior to recharging the system it shall be pressure tested with OFN. DD.12 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.
  • 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 flammable refrigerant.
  • 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 are 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 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.
  • Warning: disconnect the appliance from its power source during service and when replacing parts.
  • These units are partial unit air conditioners, complying with partial unit requirements of this International Standard, and must only be connected to other units that have been confirmed as complying to corresponding partial unit requirements of this International Standard.

02.02. Optimum Operation
According to the characteristics of cold air sinking and hot air rising, in order to improve the effect of refrigeration and heating, it is suggested that the air guide bar and the ceiling should be at an angle of 30 °~65 ° for air outlet during refrigeration and heating operation.ActronAir MOC 018CS Mini
VRF 1 Way Cassette - Optimum Operation

CAUTION
Long-term air outlet at an angle of 30 ° may cause condensation on the surface of the air guide bar. It is recommended to have the angle of the air guide bar between 30 ° and 65 °.
Operating Range
To maintain good performance, operate the air conditioner under the following temperature conditions:

Cooling Indoor Temperature 16~32 °C
Indoor Humidity ≤80%

(When the humidity exceeds 80%, long-time operation of the Indoor Unit may cause dew condensation on the surface of the Indoor Unit or generate mist-like cold air from the air outlet.)
Heating| Indoor Temperature| 15~30°C

CAUTION
The Indoor Unit operates stably within the temperature range given in the table above. If it exceeds this normal operating range, the Indoor Unit may stop running and display an error code.

Symptoms That Are Not Faults

Normal Protection of the Air Conditioner
During operation, the following phenomena are normal and do not require maintenance.

**** Protection| When the power switch is on, if you start the system right after it is stopped, it is normal that the Outdoor Unit does not operate for about four minutes as frequent compressor start/stop is not supported.
---|---
Anti-cold air protection| In heating mode (including heating in automatic mode), when the indoor heat exchanger does not reach a certain temperature, the indoor fan temporarily shuts off, or runs in Low mode until the heat exchanger heats up to prevent the blowing of cold air.
Defrosting (Heat pump type)| When the outdoor temperature is low and the humidity is high, the Outdoor Unit’s heat exchanger may become frosted, which may reduce the heating capacity of the air conditioner. If this occurs, the air conditioner will stop heating, enter automatic defrosting mode, and return to heating mode after defrosting has been completed.
During the defrosting, the outdoor fan stops running and the indoor fan runs using the anti- cold air protection function.
The defrosting operation time varies depending on the outdoor temperature and the degree of frosting. It generally takes 2 to 10 minutes.
During the defrosting process, the Outdoor Unit may emit steam due to the rapid defrosting, which is normal.
Anti Condensation| When the Indoor Unit detects high humidity, the air conditioner will adjust the louver angle and the fan speed to prevent condensation and avoid dripping. (If a third-party panel is selected, this function is not available.)

Normal Phenomena that Are Not Air Conditioner Faults
The following phenomena are normal during operation of the air conditioner. They can be solved according to the instructions below or do not need to be solved.

The Indoor Unit emits white mist| 1. In an environment where the indoor relative humidity is too high, when the Indoor Unit runs in cooling mode, white mist may appear due to the humidity and the temperature difference between the air inlet and outlet.
2. When the air conditioner is switched to heating mode after defrosting, the Indoor Unit discharges the moisture generated from defrosting as steam.
---|---
The Indoor Unit blows dust| When the air conditioner has not been used for a long time or is used for the first time, the air filter should be cleaned. Otherwise, dust that has entered the Indoor Unit will be blown out.
The Indoor Unit emits odor| The Indoor Unit absorbs the odors of rooms, furniture or cigarettes, etc., and disperses the odors during operation. It is advised to have the air conditioner cleaned and maintained regularly by professional technicians.
Water drips on the air conditioner surface| When the indoor relative humidity is high, it is normal for condensation or slight water blowing to occur on the surface of the air conditioner.
“Self-cleaning” sound of icing| During self-cleaning, there may be a slight clicking sound for about 10 minutes, indicating that the Indoor Unit is freezing, which is normal. w
The air conditioner makes low noise| 1. When the air conditioner is in “Auto”, “Cool”, “Dry”, and “Heat” modes, it may emit a low continuous “hissing” sound, which is caused by the refrigerant flowing between the Indoor Unit and the Outdoor Unit.
2. A “hissing” sound may be heard for a short time after the air conditioner stops operation or during “defrosting”, which is caused when the refrigerant stops flowing or changes its flow.
3. When the air conditioner is in Cool mode or Dry mode, a small and continuous rustling sound can be heard, which is caused by the drain pump.
4. When the air conditioner starts or stops running, you may hear a squeaking sound which is produced by the expansion or shrinkage of parts or surrounding aesthetic materials due to temperature change. The sound will disappear when the air conditioner is running normally.
Switching from cooling/ heating (not available for cooling only units) mode to fan only mode| When the Indoor Unit reaches the set temperature, the air conditioner controller automatically stops the compressor operation and switches to the fan only mode. When the room temperature rises (in cooling mode) or falls (in heating mode) to a certain level, the compressor is restarted and cooling or heating operation is resumed.
In winter, the outdoor temperature is low, and heating effects may be decreased| 1. During the heating operation of the heat pump type air conditioner, the air conditioner absorbs heat from the outdoor air and releases it to heat the indoor air. This is the heat pump heating principle of the air conditioner.

2. When the heat pump runs in heating mode, the Outdoor Unit blows out cold air, causing the outdoor temperature to drop. When the outdoor temperature is extremely low, the heating capability of the air conditioner drops gradually. You are advised to use other heating devices for heating.

Mode conflict| All Indoor Units in the same air conditioning system can only operate in the same mode, for example, cooling, heating or others. If Indoor Units are in different modes, a conflict will occur, making the system unable to start. Make sure that all the Indoor Units operate in the same mode.
No heating or cooling options| For the same air conditioning system, if Outdoor Unit operates in changeover mode, the main wired controller allows users to select modes supported by the Indoor Units, while the wired controller of a non-master Indoor Unit displays the icon of “No heating or cooling options”. In this case, the mode setting is unavailable, and other Indoor Units operate in the same mode as the master Indoor Unit.

Be sure to use the optional accessories specified by our company.
Improper installation by yourself may result in water leakage, electric shock or fire.
Do not wash the air conditioner with water; otherwise, it may cause an electric shock.
Use a stable standing platform.
05.02. Cleaning the Air Filter

CAUTION

  • Air filters are optional.
  • Air filters can be used to remove dust or other particles from the air, and if clogged, the effectiveness of the air conditioner will be greatly reduced.
  • Therefore, be sure to clean the air filter frequently when using it for an extended period.
  • For the Indoor Unit with constant speed mode, if it is installed in a place with a lot of dust, it is recommended that you clean the filter once a month.
  • For Indoor Units with a constant air flow mode, clean the filter when you receive the reminder of the wired controller.
  • If excess dirt makes the filter difficult to clean, replace the filter.
  • Do not remove the air filter unless it is being cleaned; otherwise, it may cause malfunction.

Procedure:

  1. Remove the air inlet grille.
    Hold both hands on the clip of the return air outlet and slowly open it downward, pull it inward, and press the clip of the dust screen to take it out.

  2. Remove the filter.
    NOTE
    Only professionals can change and disassemble the filter. Any improper operations may cause electric shock or injuries due to touching rotating parts.

  3. Clean the filter.
    Clean the filter with a vacuum cleaner, with the air inlet side of the filter facing upwards.| Clean the filter with clean water (except for the activated carbon module), with  the air inlet side of the filter facing downwards.
    ---|---
    |

CAUTION
• To avoid deformation of the filter, do not use fire or a burning appliance to dry the filter.
• If the filter is heavily soiled, use a soft brush and neutral detergent to clean it, then shake off the water and dry it in a cool place.
• Non-professionals should not disassemble, replace or repair the filter.

  1. Reinstall the filter.
  2. Reinstall and close the air inlet grille by following steps 1 and 2 above in reverse.

05.03. Cleaning Air Outlets and Exteriors Panels

  1. Wipe the air outlet and panel with a dry cloth.
  2. If a stain is hard to remove, clean it with clean water or neutral detergent.
    CAUTION
    • Do not use gasoline, benzene, volatile agents, decontamination powder or liquid insecticides. Otherwise, the air outlet or panel may become discolored or deformed.
    • Do not expose the inside of the Indoor Unit to moisture, as it may result in electric shock or fire.
    • When cleaning the louver with water, do not scrub it violently.
    • If the air conditioner is used without an air filter, the accumulation of dust in the air conditioner will often cause malfunctions due to the failure to remove dust from the indoor air.

05.04. Maintenance

  1. During in-depth maintenance, the air conditioner should be cleaned and maintained by professional technicians every 2 to 3 years.

  2. For the Indoor Unit in constant speed mode, the primary efficiency filter is usually cleaned every three months.
    When operating in a dusty environment, the air flow and capacity of the filter will decrease. The filter may even become blocked, and the air conditioner performance and indoor air compromised.

  3. Preheat the unit in advance.
    When the heating season comes, power on the outdoor Unit master unit for preheating more than 4 hours before use. The preheating time depends on the weather temperature. This can make the air conditioner operate more stably and help the refrigeration oil in the air conditioner compressor to maintain the best lubrication state, which can prolong the service life of the compressor.

  4. Complete the following steps before the air conditioner is put out of use for a long period:
    • If the air conditioner is not in use for a long time due to seasonal changes, keep the unit running for 4-5 hours in fan mode until the unit becomes completely dry. Otherwise, it may grow mold indoors nd have negative health effects.
    • When not in use for a long time, power off or unplug the power plug to reduce standby power consumption, and wipe the wireless remote controller with a clean soft dry cloth and remove the battery.
    • Turn on the power switch 12 hours before using the air conditioner again. In addition, in seasons when air conditioners are frequently used, keep the power switch on. Otherwise, failures may occur.
    CAUTION
    • Before the air conditioner is idle for a long time, the internal components of the outdoor Units should be checked and cleaned regularly. For more details, please contact the customer service or special technical service department.
    • Check the return air inlet and outlet of the outdoor Unit and Indoor Unit after long periods of use to see if they are blocked; if an inlet/outlet is blocked, clean it immediately.
