Chapter 3 Transport and Installation

3.2.6Piping

Only expert engineers or personnel who have adequate knowledge of and experiences with piping installation are allowed to install piping. Potential fluid leakage or stagnant fluid may occur if disregarded.

zInstall piping properly. Failure to conduct proper piping installation may result in the entry of supplied and drained water into the inside of the building, which may cause the work area and equipment to get wet.

zKeep facility water pressure below 0.5MPa.

zMake sure the locations of IN and OUT ports for circulating fluid supply. The reverse connection inhibits proper operation of the unit.

zMake sure no entry of dust and foreign materials into the water circuit during piping installation.

zHold the piping connected port with a pipe wrench when tightening the pipe. Excessive force will damage the port and cause leaks if disregarded.

zHold the piping connected port with a pipe wrench when tightening piping.
