NOTICE

The  piping  and  other  pressure-containing  parts  shall  be
suitable  for  refrigerant.  Use  phosphoric  acid  deoxidised
seamless copper for refrigerant piping.

▪ Foreign materials inside pipes (including oils for fabrication) must

be ≤30 mg/10 m.

Refrigerant piping diameter

Use the same diameters as the connections on the outdoor units:

Liquid piping

Gas piping

Ø6.4 mm

Ø9.5 mm

Refrigerant piping material

Piping material:

 phosphoric acid deoxidised seamless copper

Flare connections:

 Only use annealed material.

Depending on the applicable legislation and the maximum
working pressure of the unit (see "PS High" on the unit name
plate), larger piping thickness might be required.

6.1.2

Refrigerant piping insulation

▪ Use polyethylene foam as insulation material:

▪ with a heat transfer rate between 0.041 and 0.052 W/mK (0.035

and 0.045 kcal/mh°C)

▪ with a heat resistance of at least 120°C

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.

6.2

Connecting the refrigerant piping

DANGER: RISK OF BURNING/SCALDING

6.2.1

To connect the refrigerant piping to the
indoor unit

WARNING: MILDLY FLAMMABLE MATERIAL

The refrigerant inside this unit is mildly flammable.

Pipe length

. Keep refrigerant piping as short as possible.

1

Connect refrigerant piping to the unit using 

flare connections

.

2

Wrap  the  refrigerant  piping  connection  using  vinyl  tape,
overlapping  at  least  half  the  width  of  the  tape  with  each  turn.
Keep  the  slit  of  the  heat  insulation  pipe  cover  up.  Avoid
wrapping the tape too tight.

Insulate 

the  refrigerant  piping,  interconnection  cable  and  drain

hose  on  the  indoor  unit:  See 

"8.1  To  insulate  the  drain  piping,

refrigerant piping and interconnection cable"

 [

 9].

NOTICE

Make  sure  to  insulate  all  refrigerant  piping.  Any  exposed
piping might cause condensation.

6.2.2

To check refrigerant piping joints for leaks
after charging refrigerant

1

Perform  the  leak  tests  according  to  instructions  in  the  outdoor
unit installation manual.

2

Charge refrigerant.

3

Check for refrigerant leaks after charging (see below).

Tightness test of field-made refrigerant joints indoors

1

Use a leakage test method with a minimum sensitivity of 5 g of
refrigerant/year.  Test  leaks  using  a  pressure  of  at  least  0.25
times  the  maximum  working  pressure  (see  "PS  High"  on  the
unit nameplate).

If a leak is detected

1

Recover the refrigerant, repair the joint, and repeat the test.

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

Do NOT connect the power supply to the indoor unit. This
could result in electrical shock or fire.
