5.2
Connecting the refrigerant piping
DANGER: RISK OF BURNING
5.2.1
To connect the refrigerant piping to the
indoor unit
CAUTION
Install the refrigerating 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.
WARNING: FLAMMABLE MATERIAL
The R32 refrigerant (if applicable) in this unit is mildly
flammable. Refer to the outdoor unit specifications for the
type of refrigerant to be used.
▪
Pipe length
. Keep refrigerant piping as short as possible.
▪
Flare connections
. Connect refrigerant piping to the unit using
flare connections.
▪
Insulation
. Insulate the refrigerant piping on the indoor unit as

1
Turn up the seams of the insulation pieces.
2
Attach to the base of the unit.
3
Tighten the cable ties on the insulation pieces.
4
Wrap the sealing pad from the base of the unit to the top of
the flare nut.
NOTICE
Make sure to insulate all refrigerant piping. Any exposed
piping might cause condensation.
5.2.2
To check for leaks
NOTICE
Do NOT exceed the unit's maximum working pressure (see
"PS High" on the unit name plate).
NOTICE
Make sure to use a recommended bubble test solution
from your wholesaler. Do not use soap water, which may
cause cracking of flare nuts (soap water may contain salt,
which absorbs moisture that will freeze when the piping
gets cold), and/or lead to corrosion of flared joints (soap
water may contain ammonia which causes a corrosive
effect between the brass flare nut and the copper flare).
1
Charge the system with nitrogen gas up to a gauge pressure of
at least 200 kPa (2 bar). It is recommended to pressurize to
3000 kPa (30 bar) in order to detect small leaks.
