This quick start manual is prepared to help users to quickly understand the product’s operating method and display content. Please read the instruction manual beforehand for detailed usage, caution on product use, and safety information to use the pump correctly.

Every care has been taken before shipping the oil mist trap, but check the following after unpacking it.

(1) Is the unit the correct model you ordered?

(2) Is the specified product (O-ring P-32) attached?

(3) Is any part damaged in transit?

(4) Is any part off position?

(1) Ambient temperature during operation: 7°C to 40°C

(2) Surface temperature during operation: Cannot be used at above 80°C

(3) Others (during storage and operation)

a. To be free from corrosive or explosive gas

b. Not to be condensing dew on the oil mist trap

c. To be free from dust and dirt

d. To be indoors

e. Do not turn the oil mist trap sideways.

f. Do not expose to direct sunlight.

g. To be away from heat source

h. Not dry atmosphere (Store the unit at a relative humidity of 10% or more.)

Select a place as free from dust and moisture as possible, where the oil mist trap can be easily installed, removed, checked, and cleaned, and install the unit perpendicularly to the pump.

The connecting screw for this unit is G3/4 by the ISO standard. Select a pump of which exhaust port connection is compatible with this standard.

Installation and Removal

(1) Make sure that the pump is at stop.

(2) Mount an O-ring (P-32, accessory) in the connection of the oil mist trap.

(3) Attach the oil mist trap to the pump exhaust port of which connection is compatible with the oil mist trap. Hold the case at the side and turn it clockwise. Do not hold the top cover to turn it.

(4) Before removing the oil mist trap, make sure that the pump is at stop and turn it counterclockwise while holding the case at the side.

If the element is clogged, the trap cannot separate oil mist completely. If much oil mist is discharged when restarting the pump after a pause for more than 20 minutes, replace the element.

It is recommended to replace the element periodically after 1500 to 2000 hours.

(1) Make sure the pump is stopped and remove the oil mist trap from the pump.

(2) Turn the screw counterclockwise with a screwdriver to remove the seal washer and screw.

(3) Remove the top cover and remove the element from inside the case.

(4) Replace the element with a new one and attach it to the element stopper. Install the top cover over the element.

(5) Install the seal washer on the screw and thread it through the case. Tighten the screws with a screwdriver to the extent that the top cover does not rattle.

A clogged element will narrow the flow path and increase the inner pressure of the pump. If the inner pressure rises to 0.03MPa(G), the relief valve will automatically be opened to prevent pressure rise.

If the relief valve is opened, it means that the element is not functioning properly. In this case, oil mist will be generated. Replace the element.
