Safety Cautions 

Please  carefully  read  this  "Safety  Cautions"  before 
installing  air  conditioner  so  as  to  ensure  correct 
installation. 
The following cautions are divided into two categories, 
related  to  safety  and  of  great  importance,  please 
carefully read. 

  Warning

…Inattention  will  lead  to  death  or 

serious injury. 

  Caution

…Inattention  will  lead  to  injury  or 

machine  damage,  and  may  also  cause  serious  injury 
according to different conditions. 

 

 

Installation  operation  must  be  conducted  by 
professional  personnel.  Do  not  conduct  without 
approval. 

 

Please  install  according  to  each  procedure  in  this 
instruction. 

Improper  installation  may  cause  water  leakage, 
electric shock or fire hazard. 

 

Please  install  the  air  conditioner  in  a  solid  place 
sufficient to bear the weight. 

Instable  base  may  lead  to  air  conditioner  falling 
and cause damage. 

 

Please  use  separate  circuit  for  power  supply.  The 
operation  of  all  the  electric  parts  must  be  in 
accordance  with  the  local  laws  and  specifications 
as well as this instruction. 

 

The operation shall be conducted by the electrician 
with professional qualification. 

Insufficient capacity or improper electric operation 
may cause electric shock or fire hazard. 

 

Use  the  specification  designated  wires;  all  the 
wires  shall  be  connected  well  to  make  connecting 
terminal  and  wire  free  from  external  force 
drawing. 

Poor  connection  and  improper  installation  may 
cause fire hazard. 

 

Straighten out and lay flat when connecting power 
line,  remote  controller  and  wire  controller  line  so 
as  to  make  electric  parts  and  wire  slot  box  cover 
fastened down. 

 

If  any  refrigerant  gas  leakage  in  installation, 
immediately 

open 

door 

and 

window 

for 

ventilation. 

The  refrigerant  gas  will  generate  toxic  gas  when 
meeting  combustion  sources  such  as  air  heater, 
furnace and stove. 

 

Please  power  off  first  before  touching  electronic 
parts. 

 

Do not touch the switch with wet hand. 

Touching switch with wet hand may cause electric 
shock. 

 

Air conditioner must be earthed. 

Earthing  wire  shall  not  be  connected  to  gas  pipe, 

tap water pipe, lightening rod or telephone line. 
Poor earthing may lead to electric shock accident. 

 

Leakage earthing breaker must be installed. 

If  leakage  earthing  breaker  is  not  installed,  there 
will be electric shock hazard or fire hazard. 

 

Please  arrange  drainage  piping  according  to  this 
instruction  to  guarantee  smooth  drainage,  and 
insulate  the  piping  in  case  of  condensed  water 
accumulation. 

Improper  piping  may  lead  to  water  leakage  and 
soak household items. 

 

Air  conditioner,  power  line  and  connecting  line 
shall be far away from more than 1m at least from 
such  electrical  equipment  as  television  set  and 
radio 

to 

prevent 

from 

interference 

of 

electromagnetic wave and noise. 

 

In  the  room  equipped  with  fluorescent  lamp 
(inverter  or  quick  start  type),  the  signal 
transmission distance of the remote controller may 
not reach the preset value. 

The  indoor  machine  shall  be  away  from 
fluorescent lamp as far as possible. 

 

Installation  should  not  be  conducted  in  the 
following places: 

(a)

 

Place where mineral oil smoke or mist or steam is 
diffused,  for  example,  kitchen.  Plastic  parts  may 
be deteriorated and damaged. 

(b)

 

Place  where  there  is  corrosive  gas  such  as  sulfur 
dioxide.  Copper  pipe  or  welding  part  may  be 
corroded to cause refrigerant leakage. 

(c)

 

Place  which  is  close  to  the  machine  generating 
electromagnetic wave. Electromagnetic wave may 
influence  the  control  system  to  make  the  air 
conditioner incapable of normally operating. 

(d)

 

Place  where  there  is  combustible  gas  leakage, 
carbon  fiber  or  combustible  dust  floating,  or 
volatile  combustible  placing  such  as  gasoline  or 
diluent. 

The  use  of  air  conditioner  in  such  places  may 
cause fire hazard. 

 

Please do not touch the fin of the heat exchanger. 

Improper  touch  may  cause  machine  damage  and 
personal injury. 

 

Please  pay  special  attention  to  product  handling. 
Do  not  handle  by  lifting  PP  strap  in  case  of  PP 
strap rupture to damage unit and harm person. 

 
 
 
 
 
 

2.

 

Before Installation 

 

Air  conditioner  shall  not  be  unsealed  before 
moved  to  the  installation  site.  If  it  is  necessary  to 
unseal,  measures  shall  be  taken  after  unsealing  to 
avoid damaging or scratching air conditioner. 

 

When  moving  the  air  conditioner  during  or  after 
unsealing, do not apply force to refrigerant piping, 
drainage  pipe  or  other  plastic  parts  in  order  to 
avoid damaging air conditioner.
