2. Inspection
When you receive a pump, you need to check the pump is the same type you ordered.
Please check there is any sign of loose bolts, spilt oil, and broken/loose Parts.
If you ordered accessories for vacuum system please check them in the box.
3. Installation
1) Preparation
Select a well ventilated area, free of dust.
The pump should be placed conveniently to monitor the oil level of the pump.
We recommend the pump is operated in the temperature over 7
°
C.
(We use vacuum oil named
‘
MR-200
’
as our default vacuum oil and it is best performance over 7
°
C.)
2) Fastening
The pump should be tightly fastened to the ground or to a secure object so as not to be moved by the vibration of the
pump. The pump should be installed and maintained horizontally all the time.
3) Connection by using Terminal box
① Open the Cover of Terminal box. You can see there is 6 cords connected.
② W2V20
’
s motor is 3 phase one. You need to connect 3 external cords to the pump.
③ By referencing the Terminal box cover, you can connect the pump to power.
④ After finishing connection please do not connect the pump to the system and check the electronic connection is proper
or not. ( If the connection is wrong motor will operate opposite and you need to change the connection)
4. Operation
1) Start up
Prior to start up, make sure that the line voltage and type of connections are appropriate.
( For all 200V motors, a
“
Delta
”
connection is applied initially)
Make sure that the oil level should be within the region between
“
LO
”
and
“
HI
”
marks.
( Ideally, 3/4 toward
“
High from
“
LO
”
)
Never operate the pump in the condition which vacuum oil is below
“
LO
”
In case of 3 phase line operation, make sure that the direction of motor rotation is the same as indicated on the body of
the pump.
2) Emergency Stop and Power Failure
There is no need of a particular procedure to prevent from loosing vacuum in case of an emergency stop or power failure.
The oil regulator build inside pump prevents Back-Flow of oil when the pump stops.
