INSTRUCTION MANUAL
ULVAC KIKO, Inc.
Important
Before Operating the UFO-003, small size oil filtration be sure to
read this instruction manual thoroughly to ensure efficient and safe
operation.

Special Notes
This pump has been used by many of our customers, but while it is rare for this to happen, this
circulating pump inadvertently stops and as a result requires repair.
The reason for this is described below.
To help prevent this circulating pump from stopping inadvertently and use it with peace of mind,
we recommend that you consider the following items.
(1) Rust forms on the circulating pump from the residual water, which
results from the pump being stopped for a long time.
(2) Foreign objects have built up in the circulator pump from
circulating extremely contaminated oil.
(1) Rust tends to form while the circulating pump is stopped. Therefore, even
after the work task is finished, continue to start up the pump only and
circulate oil.
If the pump must be stopped for a long time, separate the water sufficiently
after the vacuum pump has stopped, and drain it.
Thereafter, replace the vacuum pump oil with new oil, circulate the new oil
(without water) in the pump and then stop the pump.
(2) When the oil becomes extremely contaminated, replace it with new oil right
away.

5.Installation
5-1.Location of installation
Place it horizontally nearby a vacuum pump
Also、avoid these inadequate places for installation.
1) Places that occur rough vibrations.
2) Places that generate inflammable vapors or special gases
3) Places in high-temperature and humidity, or that suffer heat/water disasters.
5-2.Connection to vacuum pump
The model, which can be connected to our oil-sealed rotary pump, is the GCD series only.
In case of connecting to other models, an optional adaptor and additional set-up work is
necessary; please consult us for further details.
Please connect it to the vacuum pump by following the procedures described on previous
page and Section 6 below.
6.Preparation for Operation and Supplement
6-1.Place this vacuum pump the same level as oil level or lower (within 1m).
（If the unit is placed higher than the pump, the oil might flow back to the pump side）.
6-2. Connect the unit to the oil rotary pump by following the procedure on Section 4.
1) Install the attached hose nipple tubes into both the oil inlet and oil drain port of the
GCD series.
2) Connect the inlet①to the oil drain port of the vacuum pump by using the attached tube,
and fix it firmly with the hose band.
3) Connect the outlet③to the oil inlet of the vacuum pump by using the attached tube, and fix
it firmly with hose band.
6-3.For oil supplement, install the tube into the oil refill port of the Inlet side 3-way
valve.
6-4.Prepare oil as supplement: 1 litter for the UFO‐003 and necessary amount of oil for the
vacuum pump.
6-5.Turn the Inlet side 3-way valve to the oil supply port②side, and insert the tip of the
container of the supplement oil. Place the Outlet side 3-way valve face upward.
For a pressurized pump, if the connecting hose of “IN”side is too long、or vertical interval to the
vacuum pump is too wide, it will cause a failure on inlet or damages on the circulating pump.
Length of connecting hose within1.5m
Vertical interval to the pump same level or within a range of lower level of 1m

7
6-6.Plug into an outlet for single-phase 100V, and switch on. It starts operating the circulating
pump, and then the oil flows into the vacuum pump; proper amount of oil should be flown
into the pump depending on the oil level on the gauge.
After a certain amount of oil reaches at a specified level, turn the Inlet side 3-way
valve to the inlet①side from the oil supply port②
6-7.Check the oil level and any oil leakage. If the amount of oil is insufficient, turn the 3-way
valve back to the side of the oil supply port and supply oil.
7.Operation
7-1.Turn the Inlet side 3-way valve to the inlet side. Put the Outlet side 3-way valve face
upward.
7-2.Be sure that power source plug is connected to the outlet for single-phase 100V.
Turn on the main switch; it starts operating.
8.Shutdown
8-1.Turn off the main switch.
8-2.Close both the Inlet side 3-way valve and Outlet side 3-way valve (neutral position).
※The Inlet side 3-way valve faces upward; the Outlet side 3-way valve places
sideways.
Caution）The 3-way valve（both Inlet and Outlet）are never to be operational with
“closed position!” It is extremely dangerous. However, they must be closed
during its shut-down. (the oil would back up).
9.Maintenance & Check
The frequency of maintenance for the unit varies considerably, depending on how it has
been used or circumstances on the system.
Regarding the following check items, please set up plans and implement regularly
according to the circumstances.
9-1.Maintenance
Please check up the following items at least once a day while its operation.
（１） If any oil leakage from the connecting part on the vacuum pump.
（２） If any oil leakage from the connecting hose, pipes, or the main unit.
（３） If any abnormal noise from the pump.
If any trouble, follow the instructions written on the “Trouble-check List.”

10. Replacement of Element
10-1.Replace the element when: the outlet pressure of the
circulating pump is above 0.3MPa, or absorption of
the element deteriorates.
10-2.Prepare the container for oil drain beforehand.
10-3.Place the container under the drain port.
10-4.Turn off the power of the UFO-003.
10-5.Remove the drain port with a wrench.（Beware of oil
leaks).
10-6.Turn the Outlet side 3-way valve to “closed position”
(neutral position).
Turn the Inlet side 3-way valve to the refill port side.
(oil comes out).
※The O-rings are used between
filter case and housing head.

10-7.Turn on the power source of the UFO-003, and operate for
a few minutes. Drain all the oil inside.
10-8.Stop operating after making sure that draining stops
from the drain port.
10-9.Loosen the upper joint of the filter case and remove
the hose.
10-10.Remove the filter case by turning it anti-clockwise.
（If it is stiff, put rubber bands three places
around the case and turn it. It is also easy to turn it
by using a belt wrench. Should not use any other
tools for removing; it might cause damages).
10-11.Remove the element from the housing head.
10-12.After cleaning the inside and outside of the housing
area, place a new element.
10-13.Install the filter case and the hose.
10-14.Install a plug to the drain port.(Be sure to fix with the seal tape around screw area).
10-15.Supply some oil by following the directions on Section 6-2～6-7.
Caution） If the oil is badly degraded, and frequent replacement
of the element is needed, a drain valve (optional) is
very useful.
11.Oil Replacement of Vacuum Pump
11-1. For oil draining of the vacuum pump、follow the directions on Section
10-2 to 10-8. The Inlet side 3-way valve should face to the
inlet side.（The Outlet side 3-way valve is at closed position）
11-2. For supplying oil into the vacuum pump, follow the directions on
Section 6-2 to 6-7
