④
Positioning the intake port too close
to the mist generation source could
result in large amounts of mist,
cutting chips, and dust to be sucked
in, causing blow leakage and
accelerated clogging of the filters and
demister. Either provide an adequate
distance (approx. 500mm) between
the mist generation source and the
intake port, or install an impact plate
to prevent clogging from sucked-in
mist, cutting chips, and dust.

) Drain tube piping (Not required with the CRM-V 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.
