Installation Requirements
Safety
Do not remove or modify any safety or insulating
equipment from the pump. To do so may create a serious
safety hazard and may void the warranty.
WARNING
This pump is designed to pump
❑
and exhaust air and inert gases only;
it is not designed to pump explosive,
flammable, toxic, or corrosive gases.
They can cause bodily injury,
explosion, or fire.
❑
Install in an area that is not
exposed to rain, steam, or excessive
humidity. They can cause electric
shock, short circuits, and severe
bodily injury.
Before inspecting or servicing the
❑
pump, be sure the electrical supply
is disconnected.
Consult a qualified electrician
❑
whenever wiring the pump.
❑
An exhaust silencer option is avail-
able for those applications in which
it is desirable to diminish the sound
level produced by the pump.
To prevent bodily injury, avoid
❑
exposing any part of the human
body to vacuum.
CAUTION
Although the pump can pump trace
particulates normally found in the
atmosphere, it is not designed for
process solids, chemicals, powders,
solvents, condensates, or other par-
ticulates. They can damage the
equipment, degrade its perfor-
mance, or shorten its useful life.
Single and three phase pumps oper-
ate in a clockwise direction when
viewed from the motor end. (Note
the arrow on the pump frame.)
Improper rotation can cause perma-
nent damage to the pump.

TriScroll 300 Series Vacuum Pump
During operation, the following environmental conditions
should not be exceeded:
Temperature:
+5 °C to +40 °C (+41 °F to +104 °F)
Relative humidity:
50 to 80% (non-condensing)
CAUTION
Do not block the fan ducts because
the pump can become overheated.
A pump surface temperature in
excess of 55 °C (131 ° F) is poten-
tially damaging. If such conditions
are observed, turn pump off and
allow to cool. Disassemble, inspect
for damage, and repair if necessary.
CAUTION
As supplied from the factory, the
pump is configured as shown in the
following table. Verify that the con-
figuration matches the supply volt-
age.
If voltage changeover is required,
configure the voltage as described in
"Electrical Connections" on page 36
and page 37.
CAUTION
To reduce the risk of electric shock,
do not expose to rain; store indoors.
