  Install  the  water  discharge  piping  according  to  the  steps 

described  in  this  manual,  and  make  sure  that  the  water 
discharge  is  smooth,  and  the  piping  is  properly  insulated  to 
prevent  condensation.  Improper  installation  of  the  water 
discharge piping may lead to water leakage, and damage the 
indoor furniture.

  When  mounting  the  indoor  and  outdoor  units,  make  sure  the 

power cord is installed at a distance of at least 1 m away from 
any TV or radio so as to prevent noise or interference with the 
images.

  The refrigerant required for the installation is R410A. Make sure 

the refrigerant is correct before installation. Incorrect refrigerant 
may cause the unit to malfunction.

  Do not install the air conditioner in the following places:

1) Where there is oil or gas, such as the kitchen. Otherwise, the 

plastic parts may age, fall off or water may leak.

2) Where there are corrosive gases (such as sulphur dioxide). 

Corrosion in the copper pipes or welded parts may cause the 
refrigerant to leak.

3) Where there are machines emitting electromagnetic waves. 

Electromagnetic  waves  may  interfere  with  the  control 
system, causing the unit to malfunction.

4) Where there is a high salt content in the air. When exposed 

to  air  with  a  high  salt  content,  the  mechanical  parts  will 
experience  accelerated  ageing  which  will  severely 
compromise the service life of the unit.

5) Where  there  are  major  voltage  fluctuations.  Operating  the 

unit  using  a  power  supply  system  that  has  large  voltage 
fluctuations  will  reduce  the  service  life  of  the  electronic 
components,  and  cause  the  unit's  controller  system  to 
malfunction.

6) Where  there  is  a  risk  of  leakage  of  flammable  gases. 

Examples are sites that contain carbon fibres or combustible 
dust in the air, or where there are volatile combustibles (such 
as diluent or petrol). The above gases may cause explosion 
and fire.

Caution

7) Do not touch the fins of the heat exchanger as this may lead to 

injury.

8) Some products use the PP packing belt. Do not pull or tug on 

the PP packing belt when you transport the product. It will be 
dangerous if the packing belt breaks.

9) Note the recycling requirements for nails, wood, carton and 

other packaging materials. Do not discard these materials 
directly as these may lead to bodily harm.

10)Tear up the packaging bag for recycling to prevent children 

from playing with it, and leading to suffocation.

11)The appliance shall not be installed in the laundry.

When the product is used for comercial application. This 
appliance is intended to be used by expert or trained users in 
shops, in light industry and on farms, or for commercial use by lay 
persons,the sound pressure level is below 70 dB(A).
