1 Safety Precaution 

   

  Please take note of the safety item as followings before and after installation process: 

1

1 Preparation before Installation 

● 

To check the electrical power supply condition, electrical power supply shall meet the requirement of local concerned rule and regulation;   

● 

The  tolerance  of  voltage  shall  be  less  than 

±

10%  based  on  the  nominal  voltage,  It  is  not  allowed  to  share  the  same  power  cable  for 

welding, which will cause the vibration of power supply; 

● 

To  install the equipment  , it  is  a must to have  professional technician  or Engineer to conduct the  installation,  otherwise, If installation  is 

completely improperly, will cause units leakage of water, electric power and cause fire accident etc; 

● 

Please follow up the installation instruction of this manual to avoid any leakage of water, electric power and cause fire 

● 

To set up an independent electrical power supply cable and meet the local concerned rule and regulation; 

● 

Before installation of outdoor units, it shall build a solid base in the ground, also to take some measure to prevent the typhoon, earthquake 

etc;   

● 

The floor or base for installation of units shall be strong enough to support the weight of outdoor units; If intensity is not enough will cause 

unnecessary damage of units and loss; 

● 

To prepare the installation kits and protection kits , such as glove, uniform to avoid any kind of injury; 

1

2 Safety Notice on processing of installation 

● 

Do  not  touch  the  fins  of  heat  exchanger;  Improper  installation  will  cause  body  injury  and  fins  damage  to  cause  low  heat  exchange 

efficiency; 

● 

Do fix the outdoor unit tightly, to avoid any vibration; The cover panel of controller box shall be fixed tightly to avoid any dirt, water to enter 

to cause some failure and damage;     

● 

When installing the indoors units, please be sure the use the air filter and electrical heater provided by the supplier; 

● 

When  installing  the  units,  in  case  the  leakage  of  refrigerant,  please  open  the  window  and  door  for  good  ventilation;  to  avoid  any  fire 

because of the poisonous gas may occurred;   

● 

If the indoor unit is installed in a confined limited space, it shall take prevent measure to avoid leakage of refrigerant; 

● 

Cable of electrical power shall be far away from water, humidity, to avoid leakage of power and fire accidence; 

● 

Do not change any protector setting, otherwise it will cause units failure , fire or explosion; 

● 

Do not use the addition to check leakage of refrigerant; 

● 

Please do not pull the cable of electrical power too tight, otherwise it will cause the breakage of cable; 

● 

To ensure the cable can support sufficient ampere and power consumption; 

● 

Units earthling is a must, to avoid any leakage of electrical power ;    do not to connect earth line with telephone line; 

● 

Indoor  condensing  water  shall  be  drainage  in proper  way,  to avoid  dripping  of condensing  water,  it  shall  have the  insulation material to 

wrap the outside layer of piping;   

● 

Products shall be handled and carried very carefully, to find the profession people and right equipment for package and transportation of 

units; 

● 

After proper installation, it shall check the air tightness, to make sure no leakage of piping; 

1

3 Notice of test operation 

● 

Before running the units, it shall to start the main switch for 12 hours, if not do in this way, it will cause the damage of components; The 

power shall be in standby condition if units are required to operation frequently; 

● 

Do not to contact the main power switch if the hand is wet to avoid leakage of electrical power; 

● 

Do  not  to remove  the  front panel or  protection  guard  when  units  is  on operation;  the  high speed  running part  of  the operation  units  will 

cause unnecessary damage and injury; 

● 

Do not the touch the refrigerant piping when units is running or just stop running, to avoid unnecessary hurt for hand because the piping 

maybe too hot or too cold; 

● 

Do not switch off the power when units stop running, wait for 5 minutes to shut off the electrical power; 

 

                                                         

Warning 

For safety and proper installation of the units, please read this manual carefully before installation
