If  the  temperature  is  higher  than  30°C  and  the  humidity  is  higher
than RH 80%, the thickness of the insulation materials should be at
least  20  mm  to  prevent  condensation  on  the  surface  of  the
insulation.

13.2

Connecting the refrigerant piping

DANGER: RISK OF BURNING/SCALDING

INFORMATION

▪ For 

liquid piping

, use a flare connection.

▪ For 

gas  piping

,  use  the  attached  piping  (accessory)

and  fix  it  with  the  hexagon  head  bolts  and  spring
washers (accessory)

13.2.1

To connect the refrigerant piping to the
indoor unit

CAUTION

Install  the  refrigerant  piping  or  components  in  a  position
where  they  are  unlikely  to  be  exposed  to  any  substance
which  may  corrode  components  containing  refrigerant,
unless  the  components  are  constructed  of  materials  that
are  inherently  resistant  to  corrosion  or  are  suitably
protected against corrosion.

Pipe length

. Keep refrigerant piping as short as possible.

 using the attached piping (accessory).

Fix  it  to  the  unit  using  hexagon  head  bolts  (M10×40)
(accessory) and spring washers (accessory). Place sealing (on
the attached piping) between the connection.

NOTICE

▪ Join  the  attached  piping  (accessory)  and  the  field

refrigerant piping (field supply) by brazing before fixing
the attached piping to the unit.

▪ Do  NOT  braze  the  refrigerant  piping  directly  to  the

indoor unit.

CAUTION

Do  NOT  reuse  sealing  (on  the  attached  piping).  Always
use new sealing to prevent refrigerant gas leaks.

Electrical installation

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

Use  an  all-pole  disconnection  type  breaker  with  at  least
3  mm  between  the  contact  point  gaps  that  provides  full
disconnection under overvoltage category III.

WARNING

If the supply cord is damaged, it MUST be replaced by the
manufacturer,  its  service  agent  or  similarly  qualified
persons in order to avoid a hazard.

WARNING

Prevent hazards due to inadvertent resetting of the thermal
cut-out:  power  to  this  appliance  MUST  NOT  be  supplied
through  an  external  switching  device,  such  as  a  timer,  or
connected to a circuit that is regularly turned ON and OFF
by the utility.
