The  following  precautions  include  important  safety  items. 
Observe them and never forget.

 

Keep  this  manual  in  a  handy  place  for  future  reference. 

Before  out  from  factory,  FAN  COIL  UNIT  (AIR  UNITS)  has

 

passed Fan Coil Overpressure Resistant  Test,  Statically

 

and  Dynamically  Balanced  Adjustment,  Noise  Test,  Air 
(cool)  Volume  Test,  Electric  Property  Test,  Outline  Quality 
Detection.

 

 

This  appliance  can  be  used  by  children  aged  from  8  years 
and  above  and  persons  with  reduced  physical,  sensory  or 
mental  capabilities  or  lack  of  experience  and  knowledge  if 
they  have  been  given  supervision  or  instruction 
concerning  use  of  the  appliance  in  a  safe  way  and 
understand  the  hazards  involved.  Children  shall  not  play 
with  the  appliance.  Cleaning  and  user  maintenance  shall 
not be made by children without supervision.

 

 

 

 

The safety precautions listed here are divided into two categories. In 
either case, important safety information is listed which must be read 
carefully.

 

 

WARNING

 

 

Failure to observe a warning may result in serious injuries. 

 

CAUTION

 

 

Failure to observe a caution may result in injury or 
damage to the equipment.

 

 

After  completing  the  installation,  make  sure  that  the  unit  operates 
properly  during  the  start-up  operation.  Please  instruct  the  customer 
on how to operate the unit and keep it maintained.

 

 

 

 

WARNING

 

 

Be  sure  only  trained  and  qualified  service  personnel  to 
install, repair or service the equipment.

 

Improper  installation,  repair,  and  maintenance  may  result  in 
electric  shocks,  short-circuit,  leaks,  fire  or  other  damage  to 
the equipment.

 

Install according to this installation instructions strictly.

 

If  installation  is  defective,  it  will  cause  water  leakage, 
electrical shock and fire.

 

 

When  installing  the  unit  in  a  small  room,  take  measures 
against to keep refrigerant concentration  from exceeding 
allowable safety limits in the event of refrigerant leakage. 

Contact  the  place  of  purchase  for  more  information. 
Excessive refrigerant in  a closed  ambient can  lead  to  oxygen 
deficiency.

 

 

Use  the  attached  accessories  parts  and  specified  parts 
for installation.

 

otherwise,  it  will  cause  the  set  to  fall,  water  leakage, 
electrical shock and fire.

 

 

The appliance must be installed 2.3m above floor. 

The appliance shall not be installed in the laundry.

 

Before  obtaining  access  to  terminals,  all  supply  circuits 
must be disconnected.

 

 

The  appliance  must  be  positioned  so  that  the  plug  is 
accessible.

 

 

The  enclosure of the  appliance  shall be  marked by word, 
or by symbols, with the direction of the fluid flow.

 

 

For  electrical  work,  follow  the  local  national  wiring 
standard, regulation and this  installation instructions. An 
independent circuit and single outlet must be used.

 

If  electrical  circuit  capacity  is  not  enough  or  defect  in 
electrical work, it will cause electrical shock fire.

 

 

Use  the  specified  cable  and  connect  tightly  and  clamp 
the  cable  so  that  no  external  force  will  be  acted  on  the 
terminal.

 

If  connection  or  fixing  is  not  perfect,  it  will  cause  heat-up  or 
fire at the connection.

 

 

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  a  similarly  qualified 
person to avoid a hazard.

 

 

An  all-pole  disconnection  switch  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.

 

 

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.

 

 

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

 

 

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

 

 

The cool water  in the  unit  is not lower than 3ºC hot water is 
not higher than 65ºC. Water in the unit must clean, air quality 
must meet to the standard of PH=6.5~7.5.
