1. For piping:
(1) The pipe diameter should not be smaller than the diameter of the unit
connections.
(2) For steam piping, make sure the piping is connected with a downward
slope on the downstream side.
(3) The piping should be kept simple, with as few joints as possible in order to
avoid pressure loss.
(4) Make sure that the piping is arranged so that air does not accumulate
inside the piping. Take measures for the location where air may
accumulate, such as installing an air vent valve, etc. so that air does not
accumulate.
