Safety Precautions To prevent personal injury, injury to others or property damage, please comply with the following: Incorrect operation due to failure to follow instructions below may cause harm or damage, the seriousness of which is classified as below: This appliances is not intended for accessibility by the general public. WARNING This sign warns of death or serious injury. CAUTION This sign warns of injury or damage to property.
Safety Precautions Do not insert your fingers or other objects into the air conditioner indoor or outdoor unit, rotating parts may cause injury. To prevent overheating, fire or electric shock: • Insert the power plug properly. • Dust on the power plug should be periodically wiped with a dry cloth. Do not touch the outdoor unit during lightning, it may cause electric shock. Stop using the product if any abnormality/failure occurs and disconnect the power plug or turn off the power switch and breaker.
CAUTION Indoor unit and outdoor unit Do not wash the indoor unit with water, benzine, thinner or scouring powder to avoid damage or corrosion at the unit. Do not use for preservation of precise equipment, food, animals, plants, artwork or other objects. This may cause quality deterioration, etc. Do not use any combustible equipment in front of the airflow outlet to avoid fire propagation. Do not expose plants or pet directly to airflow to avoid injury, etc.
Safety Precautions WARNING This appliance is filled with R32 (mild flammable refrigerant). If the refrigerant is leaked and exposed to an external ignition source, there is a risk of fire. Indoor unit and outdoor unit The appliance shall be installed, and/ or operated in a room with floor area larger than Amin (m²) and keep away from ignition sources, such as heat/ sparks/open flame or hazardous areas such as gas appliances, gas cooking, reticulated gas supply systems or electric cooking appliances, etc.
• Any part of refrigerating circuit (evaporators, air coolers, AHU, condensers or liquid receivers) or piping should not be located in the proximity of heat sources, open flames, operating gas appliance or an operating electric heater. • The user/owner or their authorised representative shall regularly check the alarms, mechanical ventilation and detectors, at least once a year, where as required by national regulations, to ensure their correct functioning. • A logbook shall be maintained.
Safety Precautions 1. Installation (Space) • Product with flammable refrigerants, shall be installed according to the minimum room area, Amin (m²) mentioned in Installation Instructions. • In case of field charge, the effect on refrigerant charge caused by the different pipe length has to be quantified, measured and labelled. • Must ensure the installation of pipework shall be kept to a minimum. Avoid use dented pipe and do not allow acute bending.
2-2. Work • Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the precautions in #2-2 to #2-8 must be followed before conducting work on the system. • Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapour being present while the work is being performed.
Safety Precautions 2-7. 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.
3. Repairs to sealed components • 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.
Safety Precautions 7. The following leak detection methods are deemed acceptable for all refrigerant systems • No leaks shall be detected using detection equipment with sensitivity to detect leakage of 5g/year of refrigerant or better under a pressure of at least 0.25 times the maximum allowable pressure (>1.04 MPa, max 4.15 MPa), for example, a universal sniffer. • Electronic leak detectors may be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need recalibration.
9. Charging procedures • 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 refrigerating system is earthed prior to charging the system with refrigerant.
Safety Precautions 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 refrigerating system unless it has been cleaned and checked.
Precautions for Use Installation • This air conditioner must be installed properly by qualified installation technicians in accordance with the Installation Instructions provided with the unit. • Before installation, check that the voltage of the electric supply in your home or office is the same as the voltage shown on the nameplate. WARNING Avoid the following locations for installation. • Locations where smoke or combustible gas exists. Also locations of extremely high temperature such as a greenhouse.
Names of Parts Indoor Unit At standard installation (Horizontal installation in the ceiling, rear side air intake) Air outlet duct * Suspension bolt * Air outlet grille * NOTICE: This air conditioner incorporates a device that generates a biocidal product. Free radicals generated by a device incorporated in the air conditioner have the capacity to inhibit pollutants, such as certain types of bacteria, viruses, mould. Active substances : Free radicals generated in situ from ambient air or water.
Maintenance WARNING CAUTION • For safety, be sure to turn the air conditioner off and disconnect the power before cleaning. (Otherwise, electric shock or injury may result because the fan is rotating at high speed.) • Do not pour water on the indoor unit. (This may damage the internal components and cause an electric shock hazard.) • Never use solvents or harsh chemicals. Also, do not wipe plastic parts using very hot water. (This may cause deformation or change in colour.
Maintenance Operation Mechanism ■ Heating performance • This air conditioner utilizes outside air for heating; its heating performance reduces as outside temperature decreases. - In the event that heating is not sufficient, please use an additional heating appliance. ■ Defrosting • This appliance may start defrosting operation to melt frost formed in the outdoor unit. 1. Defrosting starts: The indoor unit fan stops (or the speed becomes extremely slow). - “ ” (STANDBY) appears. 2.
How to Use: nanoe™X Function Display during operation of nanoe™X Example: Initial screen of remote controller 20:30 (THU) room A MODE COOL SET TEMP. FAN SPEED 28 °C FLAP : Under operation of nanoe™X nanoe™X For a freshness and cleaner environment nanoe™X generates negative ions using the air in the room to give a healthy air. It also reduces the smell in the room, and constrains propagations of mold and bacteria. When purchased, the nanoe™X function is designed to automatically operate.
Troubleshooting Check before consulting or requesting services. Symptom Cause / Action Indoor Unit Noise Sound like streaming water is heard during operation or after operation. Cracking noise is heard during operation or when operation stops. Discharged air smells during operation. Dewdrops accumulate near the air outlet during cooling operation. Fog occurs during cooling operation. Fog occurs during heating operation. The fan is rotating for a while even though operation stops. Dust is discharged.
