SAFETY PRECAUTIONS

!

 WARNING

!

 CAUTION

 Installation  and  maintenance  should  be  performed  by 
qualified  persons  who  are  familiar  with  local  code 
and  regulation,  and  experienced  with  this  type  of 
appliance.
 All field wiring must be installed in accordance with the 
national wiring regulation.
 Ensure that the rated voltage of the unit corresponds to 
that of the name plate before commencing wiring work 
according to the wiring diagram.
 The  unit  must  be  GROUNDED  to  prevent  possible 
hazard due to insulation failure.
 All electrical wiring must not touch the water piping or 
any moving parts of the fan motors.
 Confirm  that  the  unit  has  been  switched  OFF  before 
installing or servicing the unit.
 Risk  of  electric  shock,  can  cause  injury  or  death. 
Disconnect  all  remain  electric  power  supplies  before 
servicing.
 DO  NOT  pull  out  the  power  cord  when  the  power  is 
ON. This may cause serious electrical shocks which may 
result in the fire hazards.
 Keep  the  indoor  and  outdoor  units,  power  cable  and 
transmission wiring, at least 1m from TVs and radios, 
to prevent distorted pictures and static. {Depending on 
the type and source of the electrical waves, static may 
be heard even when more than 1m away}.

Please take note of the following important points when 
installing.

 Ensure that the drainage piping is connected properly. 

If the drainage piping is not connected properly, it may 
cause water leakage which will dampen the furniture.

 Ensure  that  the  unit’s  panel  is  closed  after  service 
or installation.

Unsecured panels will cause the unit to operate noisily.

 Sharp edges and coil surfaces are potential locations 
which may cause injury hazards. Avoid from being 
in contact with these places.

 Before  turning  off  the  power  supply  set  the  remote 
controller’s  ON/OFF  switch  to  the  “OFF”  position  to 
prevent the nuisance tripping of the unit. 

If this is not done, 

the unit’s fans will start turning automatically when power 
resumes, posing a hazard to service personnel or the user.

Do not install the units at or near doorway.
 Do not install the units at area like hot spring or oil 
refinery plant where sulphide gas exists.
 Do not operate any heating apparatus too close to the 
air conditioner unit or use in room where mineral oil, 
oil vapour or oil steam exist, this may cause plastic 
part to melt or deform as a result of excessive heat 
or chemical reaction.
 When  the  unit  is  used  in  kitchen,  keep  flour  away 
from going into suction of the unit.
 This unit is not suitable for factory used where cutting oil 
mist or iron powder exist or voltage fluctuates greatly.
 Ensure  the  color  of  wires  of  the  outdoor  unit  and  the 
terminal markings are same to the indoors respectively.
 IMPORTANT : DO NOT INSTALL OR USE THE AIR 
CONDITIONER UNIT IN A LAUNDRY ROOM.
 Don’t  use  joined  and  twisted  wires  for  incoming 
power supply.
 The equipment is not intended for use in a potentially 
explosive atmosphere.
