（1） Pressure guide tube thickness should be appropriate, the general inner diameter is 6 10mm, the length should be as short as possible, the maximum length should not be more than 50M, in order to reduce the delay of pressure indication. Má tá sé os cionn 50m, ba cheart an tomhas brú is féidir a tharchur achar fada a roghnú.
（2） When the pressure guide pipe is installed horizontally, it should be guaranteed to have a tilt of 1:10 1:20 to facilitate the discharge of the liquid (or gas) accumulated in it.
（3）Nuair is furasta an meán tomhaiste a chomhdhlúthú nó a reo, is gá píblíne rianaithe caomhnaithe teasa a chur leis.
（4）There should be a cut-off valve between the pressure outlet and the pressure gauge to prepare for the use of maintenance pressure timing. Ba cheart an chomhla scoite a shuiteáil in aice leis an asraon brú.
