■INTRODUCTION
Thank you for purchasing the MJ Series Mist Collector. To ensure its long use and operational
safety, read this operation manual carefully before operating the product. After reading the
manual, keep it close at hand so that you can refer to it when necessary.
■
The MJ Series Mist Collector is to be mounted on a machine tool in order to collect water-soluble
mist or *oily mist.
※ If high density mist is drawn in, the MJ unit may not be able to process it completely, causing the mist to leak
from the outlet. Therefore, attach an after filter (option) before collecting high density or oily mist.
■
The MJ unit is not equipped with a protective device for the motor. Thus, power must be supplied
from the machine tool circuit equipped with a protective device. (See page 16 for power connection
details.)
■
To operate the MJ unit separately, provide an electrical component equipped with a protective
device (electromagnetic switch with thermal relay, fuse-less breaker, or earth leakage breaker).
■The installation of optional parts will render the product inapplicable for CE conformity (excluding
the use of ducts, cuffs, or hose clamps).
■The use of non-standard power supply voltage specs will render the product inapplicable for CE
conformity (power supply specs other than 3-phase 200V 50Hz/60Hz or 3-phase 220V 60Hz are
inapplicable).
■The MJ series need a periodical check to maintain the designed performance. (Refer to page 31 for
the periodical check.)
■ The manufacturer and dealers are not responsible for accidents or damage due to the following causes.
・Improper operating conditions or usage different from that specified in this manual.

－１２－
 The lifting hooks on the unit may only be used for suspending the MJ unit. If a frame is placed below
the unit, it may not be suspended.
１） A rubber vibration damper is placed between the MJ unit and the base at the bottom. This
rubber piece is supporting the unit. Therefore, if the lifting hooks on the unit are used to
suspend the unit with a frame attached to it, the attached frame could fall off.
２） When a frame is attached to the unit, its center of gravity becomes high. If the unit is
suspended in this condition, it could lose balance and topple.
 If you mount an optional frame with casters, use the casters only for moving. During operation, secure
the frame in place and take proper measures to prevent it from toppling.
 Attach the duct hose to the inlet and secure firmly with a hose band, clamps, etc.
 To prevent mist from accumulating inside, do not allow the duct hose at the inlet to droop down in the
middle of its routing. To minimize its suction resistance, keep the duct hose as short as possible.
 Allow a space of 50 cm or more above the outlet hole.
 Keep the operating ambient temperature between 5 and
40°C.
 Keep the operating ambient humidity between 10 and 90%
(no condensation).
 According to IEC-60664-1, the unit is rated at “pollution
degree 3”.

 On the machine tool side where the mist is generated, it is recommended to allow an ample clearance
between the mist source and the inlet or provide a baffle plate between them, in order to keep the
admission of cutting chips to a minimum.
Storage Conditions
Observe the following conditions for storing the unit. Failure to do so can cause the product to
malfunction or prevent it from realizing its full performance.
 Install the unit indoors away from direct contact with rain, mist, and sunlight.
 Keep the temperature between 5 and 40°C and humidity between 10 and 90％(no condensation)

Installing the Drain Hose
After finishing the installation, attach the drain hose. The drain port has 1-inch female threads. Place
the tip of the drain hose 100 mm or more in the oil. The length of the drain hose to the recovery
container should be 250 mm or longer.
NOTE:
When the collected mist accumulates inside the unit, its collection efficiency decreases. In addition,
the collected mist can blow out of the drain port. Therefore, be sure to attach a drain hose properly.
１Attach the drain hose.
Attach the male-female elbow and the hose nipple to the drain port (1-inch female threads).
Then, attach the drain hose (ф25mm bore) and secure it in place with the hose clamp.
２Place drain hose in recovery container oil
the same oil as that in the collected mist into the oil pan and therein, sink the drain hose until
more than 100mm in length from its top end is submerged in oil. The length of the drain hose
from drain hole to oil surface of the drain pan should be more than 250mm.
During operation, vacuum (suction force) acts also on the drain port. In order to cancel out
the vacuum, a distance of 250 mm or longer is required between the hose and the recovery
container. The tip of the hose must be placed 100 mm or longer in the oil. Without its tip
being placed in the oil, the drain hose will draw in outside air instead of draining oil.
