"16.1 Preparing the installation site"
WARNING
The appliance shall be stored in a room without continuously operating ignition
sources (example: open flames, an operating gas appliance or an operating electric
heater).
CAUTION
Appliance not accessible to the general public, install it in a secured area, protected
from easy access.
This unit, both indoor and outdoor, is suitable for installation in a commercial and
light industrial environment.

CAUTION
▪
Do NOT use mineral oil on flared part.
▪
Do NOT reuse piping from previous installations.
▪
NEVER install a drier to this R32 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.
