Periodic Maintenance For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air conditioner in use be cleaned and maintained regularly to ensure efficient operation of the air conditioner. When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended. Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof treatment, if necessary. As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor unit at least once every 3 months. Ask a professional for this cleaning / maintenance work. Such maintenance can extend the life of the product though it involves the owner’s expense. Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage, and even compressor failure.

Inspection before maintenance Following inspection must be carried out by a qualified installer or qualified service person.

Warnings on Refrigerant Leakage
Check of Concentration Limit
The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.
Refrigerant R32 The refrigerant R32 which is used in the air conditioner is mildly Àammable. In Europe and areas where IEC standards apply, EN/IEC 60335-2-40 is the applicable standard. The refrigerant R 32 does not have the toxicity of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. If this appliance is connected with the outdoor unit containing R32 refrigerant, refer to the Installation and Owner’s Manual attached to the outdoor unit. Refrigerant R410A The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of space, individual control, energy conservation by curtailing heat and carrying power etc. Most importantly, the multi air conditioner system is able to hold a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit imposed by the local regulation, create an opening with adjacent rooms, or install mechanical ventilation or isolation, combined with a gas leak detection device, which complies with the local regulatory requirements. The concentration calculation method is as given below. Please note the concentration limit between R32 and R410A refrigerant differs.
Total amount of refrigerant (kg) Concentration limit (kg/m³)
Min. volume of the indoor unit installed room (m³)
Refrigerant Concentration Limit shall be in accordance with local regulations.

NOTE 1 If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as
charged in each independent device.

e.g., charged amount (10 kg)

Outdoor unit e.g., charged amount (15 kg)

Indoor unit

Room A Room B Room C Room D Room E Room F
For the amount of charge in this example: The possible amount of leaked refrigerant gas in rooms A, B and C is 10 kg. The possible amount of leaked refrigerant gas in rooms D, E and F is 15 kg.

NOTE 2 The standards for minimum room volume are as follows.

1. No partition (shaded portion)

Important
2) When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective Àoor spaces at the top or bottom of the door). Outdoor unit Refrigerant piping
Indoor unit

3. If an indoor unit is installed in each partitioned room and the refrigerant piping is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

13 Appendix

Work instructions
The existing R22 and R410A piping can be reused for inverter R32 product installations.

WARNING
Confirming the existence of scratches or dents on the existing pipes and confirming the reliability of the pipe strength are conventionally referred to the local site. If the specified conditions can be cleared, it is possible to update existing R22 and R410A pipes to those for R32 models.

Basic conditions needed to reuse existing
pipes
Check and observe the presence of three conditions in the refrigerant piping works. 1. Dry (There is no moisture inside of the pipes.) 2. Clean (There is no dust inside of the pipes.) 3. Tight (There are no refrigerant leaks.)

Restrictions for use of existing pipes

In the following cases, the existing pipes should not be reused as they are. Clean the existing pipes or exchange them with new pipes. 1. When a scratch or dent is heavy, be sure to use
new pipes for the refrigerant piping works. 2. When the existing pipe thickness is thinner than the
specified “Pipe diameter and thickness,” be sure to use new pipes for the refrigerant piping works.
The operating pressure of refrigerant is high. If there is a scratch or dent on the pipe or a thinner pipe is used, the pressure strength may be inadequate, which may cause the pipe to break in the worst case. * Pipe diameter and thickness (mm)

3. When the outdoor unit was left with the pipes disconnected, or the gas leaked from the pipes and the pipes were not repaired and refilled. There is the possibility of rain water or air, including moisture, entering the pipe.
4. When refrigerant cannot be recovered using a refrigerant recovery unit. There is the possibility that a large quantity of dirty oil or moisture remains inside the pipes.

5. When a commercially available dryer is attached to the existing pipes.
There is the possibility that copper green rust has been generated. 6. When the existing air conditioner is removed after refrigerant has been recovered. Check if the oil is judged to be clearly different from normal oil.
The refrigerator oil is copper rust green in color: There is the possibility that moisture has mixed with the oil and rust has been generated inside the pipe. There is discolored oil, a large quantity of residue, or a bad smell. A large quantity of shiny metal dust or other wear residue can be seen in the refrigerant oil. 7. When the air conditioner has a history of the compressor failing and being replaced.
When discolored oil, a large quantity of residue, shiny metal dust, or other wear residue or mixture of foreign matter is observed, trouble will occur. 8. When temporary installation and removal of the air conditioner are repeated such as when leased etc. 9. If the type of refrigerator oil of the existing air conditioner is other than the following oil (Mineral oil), Suniso, Freol-S, MS (Synthetic oil), alkyl benzene (HAB, Barrel-freeze), ester series, PVE only of ether series.
The winding-insulation of the compressor may deteriorate.

NOTE
The above descriptions are results have been confirmed by our company and represent our views on our air conditioners, but do not guarantee the use of the existing pipes of air conditioners that have adopted R32, R410A in other companies.

Curing of pipes
When removing and opening the indoor or outdoor unit for a long time, cure the pipes as follows:
Otherwise rust may be generated when moisture or foreign matter due to condensation enters the pipes. The rust cannot be removed by cleaning, and new pipes are necessary.

Existing pipes: Cannot be used.

Use new pipes.

NO

Nitrogen gas pressure 0.5 MPa

Remove the existing air conditioner from the piping and carry out flushing (nitrogen pressure 0.5 MPa) to remove any remains inside of the pipe. Note: In case of twin pipes, also be sure to flush the
branching pipe.
Was largely discolored oil or a large quantity of remains discharged?
(When the oil deteriorates, the color of the oil changes to a muddy or black color.)

(If there is discharge of remains, it is judged that a large quantity of remains are present.)
YES Clean the pipes or use new pipes.

NO Connect the indoor / outdoor units to the existing pipe.
Use a flare nut attached to the main unit for the indoor / outdoor units. (Do not use the flare nut of the existing pipe.) Re-machine the flare machining size to size for R32, R410A.
