Install the suction drawing tube only for the CRD-H Series and CRH-H
Series Mistresa. Install both the suction and discharge drain tubes for the
CRN and CRH Series.
①
Be sure to
[liquid seal]
the suction drain tube.
Otherwise, the suction
drain tube sucks air
through its end, causing
the drain to flow back
but not drain. This in
turn could lead to
premature clogging of
the next step filter.
②
Do not connect the
suction drain tube with
the discharge drain tube.
③
Make sure that the
discharge drain tube is
[open to atmosphere]
.
Otherwise, it does not
drain well, possibly
causing the drain to
remain inside the main
body.
④
Use a plug or a similar
element to close the
drain tube that is not
connected to the drain
system.
