For use of units in applications with temperature alarm settings it
is advised to foresee a delay of 10 minutes for signalling the
alarm in case the alarm temperature is exceeded. The unit may
stop for several minutes during normal operation for "defrosting
the unit", or when in "thermostat stop" operation.
Tighten the flare nut according to the specified method such as
with a torque wrench.
If the flare nut is tightened too hard, the flare nut may crack after
a long time and cause refrigerant leakage.

"9. Precautions on refrigerant piping" on page 8
and follow these procedures correctly.
Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant
is in state of gas, its composition changes and the system will
not work properly).
The connected indoor unit must be the EKHBH/X008 unit
designed exclusively for R410A.
3.3. Installation
For installation of the indoor unit, refer to the indoor unit
installation manual.
Never operate the unit without the thermistors, burning of the
compressor may result.
Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.
When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.
