3 Specific installer safety instructions
Always observe the following safety instructions and regulations.
General
WARNING
Make sure installation, servicing, maintenance, repair and applied materials follow
the instructions from Daikin and, in addition, comply with applicable legislation and
are performed by qualified persons only. In Europe and areas where IEC standards
apply, EN/IEC 60335-2-40 is the applicable standard.
Unit installation (see
WARNING
The appliance using R32 refrigerant shall be stored so as to prevent mechanical
damage and in a well-ventilated room without continuously operating ignition
sources (e.g. open flames, an operating gas appliance, or an operating electric
heater). The room size shall be as specified in the General safety precaution.
CAUTION
For walls containing a metal frame or a metal board, use a wall embedded pipe and
wall cover in the feed-through hole to prevent possible heat, electrical shock, or fire.
Refrigerant piping installation (see
)
CAUTION
Piping MUST be installed according to instructions given in
62]. Only mechanical joints (e.g. braze+flare connections) that are
compliant with the latest version of ISO14903 can be used.
CAUTION
▪
Do NOT use mineral oil on flared part.
▪
Do NOT reuse piping from previous installations.
▪
NEVER install a drier to this unit to guarantee its lifetime. The drying material may
dissolve and damage the system.
CAUTION
▪
Incomplete flaring may cause refrigerant gas leakage.
▪
Do NOT re-use flares. Use new flares to prevent refrigerant gas leakage.
▪
Use flare nuts that are included with the unit. Using different flare nuts may
cause refrigerant gas leakage.
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.
