2. INSTALLATION
2. INSTALLATION
2.3.1 Inlet port Connection
*
Connection Tip
: To achieve specified pumping speed, make the length of pipeline between
vacuum chamber and the pump as short as possible. Also the internal diameter of the pipeline is
at least the same as inlet port; the narrow inlet line can reduce pumpingspeed.
You can protect the pump with applying proper accessories such as separators, filters and cooling
traps etc. between vacuum chamber and pump. However, the conductance value of the accessory
couldcause a reductioninpumpingspeed.
Connection
Connect the intake and exhaust lines with a clamp and centeringeach.
- Default : Connect to the NW25 flange supplied on the pump; use the clamp andcentering.
- Option 1 : The hose nipple can be provided upon request. Applicable to vacuum hose.
(Ф 12 OD, Ф 16 OD, Ф 26 OD for NW25, Ф 36 OD for NW40 available depending on hose size.)
- Option 2 : Screw nipple can be used. Applicable to screw valves etc.

Inlet filters can be installed for very dusty applications or pumping condensable vapor.
Valves can be used for isolating the pump from the vacuum system; to maintain vacuum when the
pump is switchedoff. Werecommendtoinstall the Angle Valve. (refer section7.2)
2.3.2 Outlet port Connection
WARNING
If the exhaust gases from the vacuum pump 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 sucked into the vacuum pump. In order to reduce the emission of
oil vapors, we recommend the installation of an additional exhaust filter (WSA oil mist trap : refer
section 7.2) especially when the oil mist can not be lead out by separate hood or duct system.
Contact WSA for the detailedinquiry.
Connection
Exhaust connecting options are the same as Inlet Connection
*
Connection Tip
: Ensure that the internal diameter of the exhaust line is at least the same as outlet
port; the narrow exhaust line can accumulate the inner pressure in the pump and it can damage
the pump seals therefore cause oil leaks. The maximum pressure in the oil case must 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

1. Unpack and Inspect
Remove all packing materials and protectivecovers.
Leave the inlet and outlet lids on before connection of the pump.
(The pump is supplied filled withoil.)
①
Check the pump and accessories if they are the same type you have ordered.
②
Check the oil level contained through the sight glass.
③
Check the pump if it has any sign of loose bolts, spilt oil, and broken/loose parts.
④
Do not use the pump if it is damaged; notify WSA with your order and serialnumber.
2. Location
The pump can be used free-standing on its baseplate.
To firmly install the pump in place, use bolts and fasten it to the ground or to a secure object
through holes in the baseplate. It is recommended to use anti-vibration pads between base plate
and fixing surface.
Locate the pump where you can check the oil level sight-glass and access the controls including
oil filling-plug, oil drain-plug, andgas-ballast.
When installing the pump in a closed housing, make sure there is sufficient air circulation.
We use vacuum oil, ‘MR-200’ as our default vacuum oil and it is recommended to use thepump
over 7 °C (45 °F)
WSA standard pump is not suited for installation in explosion hazard areas.
If you need to 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 pumps are sealed with white PE seals for domestic and ocean transport
and metal blank clamped for air shipment to maintain oil inside)
WSA pumps are shipped with oil contained inside, so take extra care not to spill it
Retain shipping seals in case you need to store the pump in the future.
Ensure that sealing surfaces are clean and scratch-free prior toassembly.
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.
Terminal box should not to exposed to excessive moisture.
