installation & owner’s manual

Wiring routing must be properly arranged so that control 
board cover is fixed properly. 

If  control  board  cover  is  not  fixed  perfectly,  it  will  cause 
heat-up  at  connection  point  of  terminal,  fire  or  electrical 
shock.

If the supply cord is damaged, it must be replaced by the 
manufacture  or  its  service  agent  or  similarly  qualifued 
person in order to avoid a hazard.

An  all-pole  disconnection  swith  having  a  contact 
separation  of  at  least  3mm  in  all  poles  should  be 
connected in fixed wiring.

When carrying out piping connection, take care not to let 
air substances go into refrigeration cycle. 

Otherwise,  it  will  cause  lower  capacity,  abnormal  high 
pressure in the refrigeration cycle, explosion and injury.

Do not modify the length of the power supply cord or use 
of extension cord, and do not share the single outlet with 
other electrical appliances. 

Otherwise, it will cause fire or electrical shock.

Carry out the specified installation work after taking into 
account strong winds, typhoons or earthquakes.

Improper installation work may result in the equipment falling 
and causing accidents.

If  the  refrigerant  leaks  during  installation,  ventilate  the 
area immediately.

Toxic gas may be produced if the refrigerant comes into the 
place contacting with fire.

The temperature of refrigerant circuit will be high, please 
keep  the  interconnection  cable  away  from  the  copper 
tube.

After  completing  the  installation  work,  check  that  the 
refrigerant does not leak.

Toxic  gas  may  be  produced  if  the  refrigerant  leaks  into  the 
room and comes into contact with a source of fire, such as a 
fan heater, stove or cooker.

To install properly, please read this "installation manual" at 
first.

The air conditioner must be installed by qualified persons.

When installing the indoor unit or its tubing, please follow 
this manual as strictly as possible.

If  the  air  conditioner  is  installed  on  a  metal  part  of  the 
building,  it  must  be  electrically  insulated  according  to  the 
relevant standards to electrical appliances.

When  all  the  installation  work  is  finished,  please  turn  on 
the power only after a thorough check.

Regret for no further announcement if there is any change 
of this manual caused by product improvement.

2.    INSTALLATION INFORMATION

Ground the air conditioner.

Do  not  connect  the  ground  wire  to  gas  or  water  pipes, 
lightning  rod  or  a  telephone  ground  wire.Incomplete 
grounding may result in electric shocks.

Be sure to install an earth leakage breaker.

Failure  to  install  an  earth  leakage  breaker  may  result  in 
electric shocks.

Connect the outdoor unit wires , then connect the indoor 
unit wires.

 

You  are  not  allow  to  connect  the  air  conditioner  with  the 
power  source  until  wiring  and  piping  the  air  conditioner  is 
done.

While  following  the  instructions  in  this  installation 
manual,  install  drain  piping  in  order  to  ensure  proper 
drainage  and  insulate  piping  in  order  to  prevent 
condensation.

Improper  drain  piping  may  result  in  water  leakage  and 
property damage.

Install the indoor and outdoor units, power supply wiring 
and  connecting  wires  at  least  1  meter  away  from 
televisions  or  radios  in  order  to  prevent  image 
interference or noise.

Depending on the radio waves, a distance of 1 meter may not 
be sufficient enough to eliminate the noise.

The appliance is not intended for use by young children 
or infirm persons without supervision.

Don't install the air conditioner in the following locations:

There is petrolatum existing.

There is salty air surrounding (near the coast).

There is caustic gas (the sulfide, for example) existing 

in the air (near a hot spring).

The Volt vibrates violently (in the factories).

In buses or cabinets.

In kitchen where it is full of oil gas.

There is strong electromagnetic wave existing.

There are inflammable materials or gas.

There is acid or alkaline liquid evaporating.

Other special conditions.
