A liquid seal loop (trap)
can be used for the
drain hose.
□
Refer to: Suctioning requirements (Page 7); Requirements for installation site (Page 10); Requirements for connecting
ductwork (Page 12)
Important
●Arrange the hose from the drain port to the oil pan by
referring to the illustration below. The difference in height
between the drain port and the oil level in the oil pan must
be as much as smooth drainage of oil can be afforded.
●When bending the hose, be careful that the hose does not
get pinched. If it does, normal drainage will not be possible.
●We recommend that the hose diameter be as large as
possible in order to reduce the possibility of the oil clogging.
(Recommended inner diameter of hose:φ25mm)
< Other drain hose connection >
･If the user requires a loop-shaped trap in the drain hose to seal the line with oil, prepare
another hose separately.
･Such loop-shaped trap cannot be availed if the waste oil includes foreign materials such
as dust, particles, etc, because the materials are accumulated at the trap and air does
not go through out. In this sense, it is necessary to check the condition of the waste oil,
and clean or replace the hose if necessary.
･If the user requires a loop-shaped trap in the drain hose to seal the line with oil, do not
immerse the end of the hose in the oil of the reservoir.

off the power on the primary side. Otherwise, it could cause electric shock or short circuit because the
high voltage equipment is inside the electronic part.
●Make sure to use the external signal wire alone. The cable used for remote control cannot be used
together with the cable of the signal output terminals and power cord (refer to the next page) by sharing
one multi-core cable.
●Use a shield cable if the remote control takes place near to the noise source, or lay the cable in a metal
conduit.
●Input the one-shot signal 500ms and over (0.5seconds).
●Amaximum of 10m wiring extension is allowed for the external-controlled operation.
●The DC 12V 10mA signal will be output from the terminal block.
●No-volt contacts shall be used in wire connection for the external controlled operation.
