Chapter 3. MOUNTING AND WIRING
„
Piping
CAUTION
Mount the device horizontally. However, do not mount it with the display fac-
ing down.
Doing so might cause measurement error or equipment failure.
When making the pipe connections, hold the hexagonal part of the connector
section and turn the pipe to tighten. After connecting, check that there are no
gas leaks.
If using Rc connections, take care not to coat with too much sealant. Foreign
matter or burrs in the pipes may also cause measurement errors.
Handling Precautions
•
Make sure that the gas flows into the device in the direction indi-
cated by the FLOW arrow on the main unit. Otherwise, the flow
rate cannot be controlled correctly.

Do not touch the pipe sections of a controller treated to be oil-
free with your bare hands. Doing so will degrade the oil-free
treatment.
•
Do not hold the top part of the main unit with your hand when
connecting piping. Doing so might deform the case.
