3.1 Gas-ballast control
The gas ballast introduces a small amount of air(or inert gas) during the compression stage in order
to adjust the saturation pressure of the vapor and it can prevent condensation of vapors in the
pump; the condensates cause contamination of the oil.
In general use, it is recommended to use the pump with gas-ballast closed.
Operating pump with GB control open will lower ultimate vacuum level and raise the temperature
of the pump body. Also it will increase the speed of oil loss from the pump.
3.2 Start-up procedure
GB control closed
GB control open
to achieve ultimatevacuum
to pump high concentrations of
condensable vapor
to pump dry gases
to decontaminate the oil
WARNING
Never operate the pump with a sealed exhaust line.
There is the danger of injury.
Ensure all vacuum connections are completely sealed before switch on the pump.
Operating pump with being exposed to normal pressure in long period of time can cause serious
mechanical troubles.
Do not operate the pump with inlet port open. It would overload the pump and cause oil loss.
Never expose any part of the body to the vacuum. It might cause personal injury.
* In case of Emergency stop or 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 built inside of the pump prevents Back-Flow of oil when the pump stops.
However, it is more recommended to vent the inlet side of the pump if it stops accidentally.
Procedure
①
Check that the pump oil-level is between the H and L marks through the oil-level sight-
glass; if it is not, refer to sec 4.3 (Never operate the pump with the oil level below L mark.)
②
Turn the gas-ballast control to the required position if you pump condensable vapor.
③
Switch on the electrical supply to the pump.
④
For 3 phase pump, check the direction of rotation of the motor.
When starting-up a pump after prolonged storage period, the actual vacuum level might not be
able to reach to the ultimate pressure, specified on the pump. It is generally because of the
contaminationofthe oil inside. Replacewithnew vacuum oil.

④
After wiring the motor, check its direction of rotation by operating the pump for short time(2~3
sec) before connecting the pump to your vacuum system. If the rotation is the opposite to the
direction of the arrow on the motor cap, change the codes from outside (ex. 1 2 3 -> 1 3 2) and
check the directionagain.
Depending on the type of application or the kind of pumped media, the corresponding regulations
and information sheets must be observed.
2.4 Electrical connection
If you don’t have knowledge of 3 phase power connection, please inquire of WSA.
WSA can not be responsible for any trouble caused by electrical connection.
* For 1 phase pump, no specific connection process is needed.
Simply connect the plug to the power.
Connection (3 phase)
①
Open the cover of terminal box. You can see 6 or 9 electric cords need to be connected.
②
For 3 phase motor, 3 external power cords and 1 extra electric cord to earth should be supplied.
③
With referring to the diagram on the back of terminal cover, connect the motor to the power.
WARNING
ELB(Earth leakage breaker) must be installed to prevent electrical accident.
Electrical connections for 3 phase must be done by a qualified electrician.
