2. INSTALLATION 2. INSTALLATION
2.3.1 Inlet port Connection
* Connection Tip : To achieve specifiedpumping speed, make the lengthof pipeline between
vacuum chamber and the pump as short as possible.Alsothe internal diameter ofthe pipeline is
at leastthe same as inlet port; the narrow inlet line can reduce pumpingspeed.
You can p rotect the p ump with applying proper accessories such as separators, filters and cooling
traps etc.between vacuum chamber and pump.However, the conductance val ue of the accessory
could cause areduction inpumpingspeed.
Connection
Connect the intake and exhaust lines with a clamp and centering each.
-Default : Connect to the NW25 flange suppliedonthe pump;use the clamp andcentering.
-Option 1 : The hose nipple canbe provided upon request. Applicableto vacuum hose.
(Ф 12 OD, Ф16 OD, Ф26 OD for NW25, Ф36 OD for NW40 available depending on hose size.)
-Option 2 : Screw nipple canbe used.Applicabletoscrewvalves etc.
(1/4″,3/8″,1/2″,3/4″, 1″for NW25, 1&1/4” for NW40; available depending on connecting devices.)
Inlet filters canbe installedfor very dusty applicationsorpumpingcondensable vapor.
Valve s can be used for isolating the pum p from the vacuum system;to maintain vacuum when the
pump isswitched off.Werecommend to install the Angle Valve.(refer section 7.2)
2.3.2 Outlet port Connection
WARNING
If the exhaust gases from the vacuumpump are harmful to human
body, these must be safely lead away and subjected to post-treatment
as required
* Connection Tip : Designing the exhaust line lower than the pump can prevent condensate
from flowing back into the pump.
Oil vapors can be discharged from the exhaust port in low vacuum section(760 Torr~10 Torr)
since the large amount of air is suckedinto the vacuum pump.In order toreduce the emissionof
oil vapors, we recommendthe installation of an additional exhaust filter (WSA oil misttrap : refer
section7.2)especiallywhenthe oil mistcannot be leadout by separate hood or duct system.
Contact WSA for the detailedinquiry.
Connection
Exhaust connecting options are the same asInlet Connection
*Connection Tip :Ensure that the internal diameter of the exhaust line is at least the same as outlet
port;the narrow exhaust l i ne can accumulate the inner pressure in the p ump and it can damage
the pump se als therefore cause oil leaks.The maximum pressure in the oil case m ust not exceed 1.5
bar (absolute).
CAUTION
If the temperature of the pump-body exceeds 70°C (158 °F),
you must fit suitable guards to prevent contact with hot surfaces.
7 8
1. Unpack and Inspect
Remove all packingmaterials and protectivecovers.
Leave the inlet and outlet lids on before connection of the pump.
(The pump issuppliedfilledwithoil.)
①Check the pump and accessories if they are the same type you have ordered.
②Check the oil level contained through the sight glass.
③Check the pump ifit has any sign of loose bolts,spiltoil, and broken/loose parts.
④Do not use the pump ifit is damaged;notify WSA withyour order and serialnumber.
2. Location
The pump canbe usedfree-standing on its baseplate.
To firmlyinstall the pump inplace,use bolts andfasten it to the ground or to a secure object
through holes in the baseplate.It is recommended to use anti-vibration pads betweenbase plate
and fixingsurface.
Locate the pump where youcan check the oil level sight-glass and access the controls including
oil filling-plug, oil drain-plug, and gas-ballast.
When installingthe pump ina closedhousing, make sure there is sufficient air circulation.
We use vacuum oil, ‘MR-200’ as our default vacuum oil and it isrecommended to use the pump
over 7 °C (45 °F)
WSA standard pump isnot suitedfor installationin explosion hazard areas.
If you needto apply the pump to such area, please contact us first.
2.3 Mechanical connection
Before connecting the WAS pump, remove the shipping seals from the inlet and exhaust
connection flanges. (WSA pumpsare sealedwithwhite PEseals for domestic and ocean transport
and metal blank clampedfor air shipmenttomaintainoil inside)
WSA pumpsare shippedwithoil contained inside, so take extra care not to spill it
Retain shipping seals in case you needto store the pump in the future.
Ensure that sealing surfaces are clean and scratch-free prior to assembly.
WARNING
Do not carry out any unauthorized conversions or
modifications on the pump
CAUTION
The pump should be set up on a flat, horizontal surface.

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 saturationpressureof the vapor and it can prevent condensation of vapors in the
pump;the condensates cause contamination of the oil.
In general use,itisrecommended to use the pump with gas-ballastclosed.
Operating pump withGBcontrol openwill 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 decontaminatethe oil
WARNING
Never operate the pump with a sealed exhaust line.
There is the danger of injury.
Ensure all vacuum connections are completely sealedbefore switch on the pump.
Operating pump withbeingexposed to normal pressureinlongperiodof time cancause serious
mechanical troubles.
Do not operate the pump with inlet port open. It would overload the pump andcause oil loss.
Neverexposeanypart of the body to the vacuum. It mightcause personal injury.
* In case of Emergencystop or Power failure
There is no need of a particular procedureto prevent from loosing vacuum incase ofan emergency
stop or power failure.
The oil regulator builtinside ofthe pump prevents Back-Flow of oil when the pump stops.
However,it ismore recommendedtovent the inlet side of the pump ifit stops accidentally.
Procedure
①Check that the pump oil-level is between the H and L marks through the oil-levelsight-
glass; if it is not, refer to sec 4.3 (Neveroperate the pump with the oil level belowLmark.)
②Turn the gas-ballastcontrol to the requiredposition if you pump condensable vapor.
③Switch on the electricalsupply to the pump.
④For 3 phase pump,check the direction of rotation of the motor.
When starting-up ap um p after prolonged storage period, the actual vacuum level might not be
able to reach to the ultimate pressure, specified on the p ump .It is ge nerall y because of the
contaminationof the oil inside.Replacewith new vacuum oil.

④After wiring the motor, c he ck its direction of rotati on by ope rati ng the pum p 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 c ode s from outside (e x. 1 2 3 -> 1 3 2) and
checkthe directionagain.
Depending on the type of applicationorthe kind of pumpedmedia,the corresponding regulations
and informationsheets must be observed.
2.4 Electrical connection
If you don’t haveknowledge of 3 phase power connection, please inquire of WSA.
WSA can notbe responsible for any trouble caused by electrical connection.
* For 1 phase pump,no specificconnection process is needed.
Simplyconnect the plugto the power.
Connection (3 phase)
①Open the cover of terminal box.You cansee 6 or 9 electriccords needto be connected.
②For 3 phase motor, 3 external power cords and 1 extra electric cord to earth shouldbe supplied.
③With referringto the diagram on the back of terminal c ove r, connect the motor to the power.
WARNING

When the pump hasbeenpumpingcorrosivemedia,we recommend to perform any possibly
planned maintenance work immediately in order to prevent corrosion of the pump.
After maintenance is completed and reconnect the power of 3 phase pump,
recheckthe pump rotation direction.
Do not reuse o-ring and seals if they are damaged.
4.2 Maintenance Frequency
The plan shown in the below Table details the r outi ne maintenance op e rati ons necessary to
maintainthe pump innormal use.
More frequent m ai nte nance may be required if the pump is used to p rocess corrosive or ab rasive
gases and vapors;in these circumstances, we recommend that you replace the p um p seals every
year.Ifnecessary, adjust the maintenance planaccordingto your experience.
When you maintainthe pump, use WAS spares and service kits;
there contain all of the components necessary to complete maintenance operations successfully.
The Item Numbers of the spares and kits are given in Section 7.1.
*WSA provides 2kinds of Service kits(Repair kits)
‘Minor Repair Kit is for the general use for overhaul and consists of various metal andrubber
parts. It contains mainly disposable parts which need to be periodicallyreplaced.

safetymeasures.
CAUTION
When disposing of used oil,
you must observe the applicable environmental regulation.
11 12
3. Decontamination of Oil
As the oil is gradually contaminatedduring operation by dissolved gases and vapors, the degas
process is necessary to prevent corrosion of the pump.Allowthe pump to continue operating with
inlet port closedand gas ballast control open until the oil is free of condensed vapors.
It is recommendedtoleave the pump being operating inthis mode for about 30 min after finishing
the process. To attain the ultimate pressure, close the gas ballast after this process.
4. SwitchingOff &Shutdown
You cansimplyswitch off to stop the pump,under normal circumstances.
* When motor is switched off while the gas ballast is open, the system pressurecan be risen slowly.
(Close the gas ballast to maintain vacuum level.)
If the pump is to be shutdown for an extendedperiodafterpumpingaggressive or corrosive media
or if the pump has to be stored, proceed as follows;
①Drain the oil through oil drain-plug.
②Add cleanoil until the oil-level is at the H mark and let the pump operate for some time.
③Drain the oil again and add clean oil until the oil level is at the H mark.
④Seal the connection ports.
WARNING
When pumping harmful substance, take adequate safety precautions.

4.3.2 Oil change
For proper operation of the pump,itisessentialthat the pump has an adequate supply ofthe
correct and clean oil at all times.
Clean vacuum oil isbasicallyodorlessandtransparent. (MR-200 ha s pale yellow color.)
As operatingpumps, the color of vacuum oil turns from yellow through orange into red brown.
This discoloration is causedby gases and foreign materials pumped in and this mixture would
impairsthe vacuum level anddamage the interior of pump.
Change vacuum oil when discoloration is dark yellow to red brown. (4 in above pictu re.)
When the color reach 6~7 with deterioration, the interior of pump woul d be damaged and
overhaul process is necessarybefore operating the pump again.
If the vacuum oil becomes cloudyasmilkcolor,it is causedbymoisture flowed in.
In this case, stop the pump and wait until the fluid is divided into two layers; vacuum oil and water.
Then drain the water layer completely throughoil drain plug.
Design the process so as moisture not to be pumpedinand install a coldtrap if necessary.
Before and after a prolonged storage, additional change of oil is required.
If the speedof deterioration of oil is too fast, applydustfilter or oil filter tothe pump.
(refer to sec 7.4 : WMT-250/400)
Contact WSA for further information.
Caution
Only change the oil after the pump has been switched off and
while the pump is still warm..
Procedure
①Remove the oil-drainplugandletthe used oil drain into a suitable container.
②When the flow of oil slows down, screw the oil-drainplugbackin,brieflyswitchon the pump
(max. 10 sec) and then switch it off again. Remove the oil-drainplugonce more and drain out the
remainingoil.
③Screw the oil-drain plug back in (check the gasket and reinstall a new one if necessary.)
④Remove the oil-fill plugandfill in with fresh oil.
⑤Screw the oil-fill plugbackin.
