3.1.2 Mounting
 During transport and installation, do not apply shock to the product,
such as by dropping doing so will affect its precision.
 For the installation posture, place it perpendicular to the ground, with
the zero point on the reading of a pressure gauge facing down.
 Do not install it in an area that is exposed to high temperature or
humidity, because doing so will lead to improper operation.
 To screw in the pressure gauge, make sure to turn the gauge by
placing a wrench over the square wrench flats. If the pressure gauge
is screwed in by holding it on some other area, air leakage or
damage may result.
 Recommended tightening torque: R 1/8: set between 7 to 9 N.m,
R1/4: 12 to 14 N.m respectively.

 Before piping make sure to clean up chips, cutting oil, dust etc.
 When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread exposed
on the end of the pipe/fitting.
 Tighten fittings to the specified tightening torque.
