NOTE

About Fluorinated Gasses
- This air-conditioning unit contains fluorinated gasses. For specific information on the type of gas and the amount,

please refer to the relevant label on the unit itself. Compliance with national gas regulations shall be observed.
- Installation, service, maintenance and repair of this unit must be performed by a certified technician.
- Product uninstallation and recycling must be performed by a certified technician.
- If the system has a leak-detection system installed, it must be checked for leaks at least every 12 months. When

the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.

Do not install the unit in the following places:
- Where there is mist of mineral oil, oil spray or vapors. Plastic parts may deteriorate, and cause them to come loose 

or water to leak.
- Where corrosive gases (such as sulphurous acid gas) are produced. Where corrosion of copper pipes or soldered

parts may cause refrigerant to leak.
- Where there is machinery which emits electromagnetic waves. Electromagnetic waves can disturb the control

system and cause equipment malfunction.
- Where flammable gases may leak, where carbon fiber or ignitable dust is suspended in the air or where volatile

flammables such as paint thinner or gasoline are handled. These types of gases might cause a fire.
- Where the air contains high levels of salt such as near the ocean.
- Where voltage fluctuates a lot, such as in factories.
- In vehicles or vessels.
- Where acidic or alkaline vapors are present.
This appliance can be used by children 8 years old and above and persons with reduced physical, sensory or mental 

capabilities or lack of experience and knowledge if they are supervised or given instruction on using the unit in a 

safe manner and understand the hazards involved. Children should not play with the unit. Cleaning and user 

maintenance should not be done by children without supervision.
Children should be supervised to ensure that they do not play with the appliance.
If the supply cord is damaged, it must be replaced by the manufaturer or its service agent or a similarly qualified 

person.
DISPOSAL: Do not dispose this product as unsorted municipal waste. Collection of such waste seperatelly for 

special treatment is necessary. Do not dispose of electrical appliances as municipal waste, use seperate collection 

facilities. Contact your local goverment for information regarding the collection systems available. If electrical 

appliances are disposed of in landfills or dumps, hazardous substance can leak into the groudwater and get into the 

food chain, damaging your health and well-being.
The  wiring must be performed by professional technicians in accordance with national wiring regulation and this 

circuit diagram. An all-pole disconnection device which has at least 3mm seperation distance in all pole and a 

residualcurrent device(RCD) with the rating not exceeding 30mA shall be incorporated in the fixed wiring according 

to the national rule.
Confirm the safety of the installation area ( walls, floors, etc. ) without hidden dangers such as water, electricity, and 

gas.Before wiring/pipes.
Before installation , check whether the user's power supply meets the electrical installation requirements of unit ( 

including reliable grounding , leakage , and wire diameter electrical load, etc. ). If the electrical installation 

requirements of the product are not met, the installation of the product is prohibited until the product is rectified.
When installing multiple air conditioners in a centralized manner, please confirm the load balance of the three-phase 

power supply, and multiple units are prevented from being assembled into the same phase of the three-phase power 

supply.
Product installation should be fixed firmly, Take reinforcement measures, when necessary.
