Important Notice
●The air conditioner for general use. Food, animals and plants, precision machinery and preservation of works of art and other special purpose,
please do not use.
●Do not install in the following places. If you have gas and oil droplets exist around, it will cause fires and machine deformation, corrosion,
damage.
○Oil (including machine oil) of the droplets, oil gas and more places. ○The sulfur gas and hot springs more places.
●Do not install in the following places, it will cause corrosion.
○Near the sea (in the salty environment). ○An acid or alkaline environment.
●When produce electromagnetic waves used in medical equipment places, please note that the air conditioner to prevent malfunction.
○Do not install the outdoor unit where the electromagnetic wave is directly radiated to the electrical box.
○Do not install the indoor unit, outdoor unit, controller and cable within approximately 3 meters from strong electromagnetic waves such as
medical equipment.
●Do not install in the animals or plants will be directly affected by the wind to the place, otherwise have adverse effects on plants and animals.

Safety Summary
●Before installation, This is a " Safety Summary " in the content, be sure to read, for the correct installation.
●In this manual to note that the "
Therefore, an important part of safety, please be sure to actually follow.
●When the installation is complete, and then test run, to confirm whether there is abnormal. Please follow the manual's instructions, using the
method, maintenance method for illustration to customers, and the installation manual and operation manual by the customers really to keep.
【Definition for signal words】
DANGER:Immediate hazards which will result in severe
personal injury or death.
About electrical works
●When perform electrical work , please have a qualified personnel. Please note that the construction is not completely by
yourself, there will be occurred an electric shock.
●Perform electrical work according to Installation Manual and all the relevant regulation and standard. If the instructions are
not followed, an electrical shock and fire may occur due to insufficient capacity and inadequate performance.
●The wiring between products, please use the specification wire. Select the wrong wire, it will cause fire or electric shock.
DANGER
●Ensure that the wiring terminals are tightened securely with the specified torques. If not, generating fire or electrical shock at
the terminals connection part may occur.
●Fix the cables securely. External forces on the terminals could lead to a fire.
●Use an ELB(Earth Leakage Breaker);In the event of fault, there is danger of an electric shock or a fire if it not used.
●Due to electrical wiring, inspection work and open the service cover, completely turn off the power to implement in order to
avoid electric shock.
●Check that the ground wire is securely connected. If the unit is not correctly grounded, it leads electrical shock. Do not
connect the ground wiring to gas piping, water piping, lighting conductor or ground wiring for telephone.
About installation
●When installation, make sure you follow the installation manual. If the instructions are not followed, it may result in a water
leakage, electric shock or a fire.
●Please install the unit where is able to withstand the weight. Strength, and installation is not complete, the body may fall and
cause injury.
●Please do not place flammable gas and have doubts about the place to the installation, it may cause fires and other
DANGER
accidents.
●Do not climb air conditioner, or place objects on top, so as to avoid falling damage.
●In case of refrigerant leakage occurs, please immediately turn off the fire source (such as: stoves and other appliances),
remove the refrigerant on the ground, open the doors and windows to ventilation , and contact your service contractor.
●The indoor unit drain pipe do not directly into the drainage ditches. The biogas will be produced through the drain pipe into
the indoor, resulting in poisoned phenomenon.
