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.
During operation, the following environmental
conditions should not be exceeded:
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
available 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.
❑The pump is a heavy object. To
avoid muscle strain or back injury,
use lifting aides and proper lifting
techniques when removing or

Power Cord
Several power cord options are available from your
Agilent dealer. Descriptions of the available power cords
and their ordering numbers are given in Table 1.
Grounding Instructions
This product should be grounded. In the event of an elec-
trical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric current.
This pump is equipped with a power cord that has a
grounding wire with an appropriate grounding plug. The
plug must be inserted into an outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
Extension Cords
If you must use an extension cord with this product:
❑Agilent recommends using only extension cords
with a minimum of 16-gauge wire and a
maximum length of 25’ (7.6 m).
❑Use only a 3-wire extension cord that accepts the
plug.
❑Ensure the extension is in good condition.
❑Ensure the extension cord is rated high enough to
carry the current the products draws. An
undersized cord causes a drop in line voltage,
resulting in loss of power and overheating.
Circuit Breakers
Table 2 lists the circuit breaker capacity required for the
pump. Locate the switch or circuit breaker near the pump.
NOTE The pump must be connected to the
power supply using a high voltage
IEC-320 type power cord of at least 10

Mechanical Connections
Pump Location
Locate the pump on a firm, level surface.
Clearance mounting holes provided in the frame can be
used to provide permanent attachment. Attach the
provided rubber mounts to the threaded holes at the
frame base to minimize vibration.
Do not to position the equipment so that it is difficult to
operate the disconnecting device.
Vacuum Pump Isolation Valve
Scroll pumps return to atmospheric pressure quickly
when shut off. Thus, an integrated fast acting, automatic,
normally closed isolation valve is standard equipment to
prevent pump debris from being transported back into the
vacuum chamber when the pump is turned off:
❑The opening of this valve must occur 350 ms
after pump startup.
❑Valve closing must occur 250 ms after pump
shut off.
The VPI Valve status is controlled by motor
operation. The VPI Valve:
❑Opens when the pump is running and
❑Closes when it is stopped due to switch off or
overload protection.
This TriScroll 800 Inverter Scroll pump includes the
necessary communication cable, needed to operate the
pump.
Pump Inlet
Use NW40, or larger, clean vacuum hardware with as
short a length as practical between the pump inlet and the
vacuum chamber.
Use a bellows to provide both vibration isolation and
strain relief between the pump and vacuum chamber.
Pump Exhaust
A female 3/8 National Pipe Thread exhaust fitting is
located underneath the scroll module. This fitting swivels
360°. Additionally, a NW25 adapter is provided with a
3/8 National Pipe Thread male thread.
Gas Ballast
The pump incorporates an automatic gas ballast to
prevent water and other condensates from accumulating
within the pump. The standard configuration is a sintered
filter installed in the 1/4" National Pipe Thread gas ballast
port (item 8 on Figure 1 on page 6). This allows enough
atmospheric air to enter the pump in order to purge
condensates while not affecting pump ultimate pressure
or pumping speed.
For applications where the ingress of atmospheric air is
undesirable, dry nitrogen at a flow rate of  5 lpm can be
bled into the gas ballast port. See item 8 on Figure 1 on
page 6. Blocking of the gas ballast port is not
recommended.
Bearing Purge
A 1/4" National Pipe Thread bearing purge port (item 5 on
Figure 1 on page 6) protects the main crankshaft bearings
in applications where large amounts of water are being
pumped. In the standard configuration, this port is sealed.
To enable the bearing purge, dry nitrogen at a flow rate of
5 lpm can be bled into the bearing purge port. This gas
supply should be maintained at 2 psig or less and must be
kept below 5 psig.
See “Purge Kit” on page 12.

DRAFT 10/9/14
Operation
In order to reach ultimate vacuum, the pump must be left
running for about one hour with the inlet sealed.
Unlike conventional oil-sealed pumps, Agilent’s dry scroll
pumps do not have fluid to cleanse them of accumulated
dust and debris. Run the pump periodically at atmosphere
for a minute or two to flush out the pump. Flush the pump
regularly and adjust this schedule according to your
specific conditions.
Startup Procedure
1. Be sure that the vacuum system isolation valve is
closed.
2. Turn on power to the pump.
3. Open the isolation valve.
Shutdown Procedure
1. Close the vacuum system isolation valve. This
prevents debris in pump from being transported into
the vacuum system.
2. Turn off power to the pump.
Maintenance
Personnel responsible for pump operation and
maintenance must be well-trained and aware of the
accident prevention rules.
If a pump is to be discarded, it must be disposed of in
accordance with specific national and local standards.
NOTE Pump operation is interlock depen-
dent. The provided mating connec-
tor must be plugged into P1 to start
the pump.
NOTE The integrated VPI solenoid must be
connected to I/O P2 with the pro-
vided communications cable prior
starting the pump.
NOTE When the controller is switched on,
an electronic self-test occurs, during
which an orange LED illuminates for
one second and the turns off for two
seconds. During this time, the pump
will not start.
This self-test time is not required if
the pump is already powered, as
when remotely or serially operated.
WARNING ❑Death may result from contact
with high voltages. Always take
extreme care and observe the acci-
dent prevention regulations in force.
❑When the machine is powered
up, be careful of moving parts and
high voltages.
❑If you have to perform mainte-
nance on the pump after a consider-
able time in operation, allow the
pump to cool as the temperature of
the outer surface may be in excess of
55 °C (131 °F).
❑Always disconnect your power
supply to the pump before beginning
maintenance work.
NOTE Before returning the pump to the
factory for repair, the Return Autho-
rization sheet attached to this
instruction manual must be com-
pleted and sent to the local sales
office. A copy of the sheet must be
inserted in the pump package before
shipping.

Pump Electrical Controller
The pump is powered by an inverter that converts single
phase line power into 3-phase power that drives an
induction motor at a user selectable frequency.
Several operational variables are modifiable through the
J2 serial port when using Agilent T-Plus software. A
number of additional system variables are also viewable.
Pump operation is interlocked through the P1 connector.
Pins 4 and 5, and Pins 8 and 9, must be connected
together to enable operation. A prewired connector is
supplied with the pump and should be plugged into P1.
The maximum power output of the inverter is 950 Watts.
At pump inlet pressures above approximately 20 Torr, the
pump will be power limited and the output frequency
will be reduced. This mode is known as autotuning.
At pump start, the drive frequency is ramped up over
several seconds. This provides for smooth starting and
eliminates large in-rush currents.
Technical Specifications
❑Input voltage: 200 V-240 V / 50-60 Hz
❑Max frequency: 65 Hz, factory set @ 62Hz
❑Normal Operation maximum power: 850 W
❑Protection level: IP 20
Remote speed setting allows you to control rotational
speed using a 0-10 V analog input:
❑Vin > 9 V: Driving frequency will be the full
speed (factory set @62 Hz)
❑Vin <1 V: Driving frequency will be the minimum
speed (35 Hz)

one second and the turns off for two
seconds. During this time, the pump
will not start.
This self-test time is not required if
the pump is already powered, as
when remotely or serially operated.

TriScroll 800 Inverter Vacuum Pump

pump is power limited and will run at a lower
frequency (auto-tuning mode). This condition
continues until the power required drops below 750
Watts.
The target frequency is stored in the inverter even
when power to the pump is removed.
Purge Kit
A purge kit (Agilent part number PTSPURGEKIT) is
available to properly purge either the bearing purge or the
gas ballast. This kit contains a flowmeter and all
necessary valving and tubing.
Exhaust Silencer Kit
In certain applications it is desired to lower the noise
level emitted by the pump. For these cases, Agilent offers
Exhaust Silencer Kits (P/N EXSLRTRISCROLL, Manual
P/N: 699904380), which breaks up noise pulsation in the
discharge line.
The Exhaust Silencer Kits contain two basic components,
as well as installation hardware. A cylindrical resonator
chamber has been selected to attenuate the frequencies
associated with the exhaust gas pulsation noise. The
resonator is then plumbed to an exhaust muffler/filter.
This muffler provides the majority of the actual noise
reduction. It also contains an integral 5-micron paper
filter element to capture any tip seal debris. This paper
filter is replaceable; the recommended service interval is
whenever the pump tip seal or module maintenance is
performed.

Vibration Isolation Kit
A set of vibration isolation mounts (P/N PTSVIBISOKIT,
Manual P/N: 699904385) are available for Agilent scroll
pumps. These are used in place of the standard feet
installed on the pump for applications that require
minimal vibration transmission from the pump to the
installation. They can be used alone, or with inlet flexible
bellows to provide pump isolation.
The vibration isolation mounts in the Vibration Isolation
Kit have been designed to ensure the lowest vibration
level transmitted at the base of the pump.
Vibration level in every direction (axis), transmitted to the
surface the pump sits on, is reduced by a significant
amount. Typical vibration reduction levels are 75% for
the TriScroll 800 pump.
The TriScroll Vibration Isolation Kit consists of (4)
vibration isolation mounts. They have a M6 metric
threaded screw to attach to the TriScroll frame; the screw
is provided.
These mounts increase the height of the TriScroll pumps
by 0.75" compared to the standard mounting feet.
HEPA Inlet filter
Agilent now offers inlet filters for the scroll pumps, which
protect the pump from ingested particles, and keep
particles from migrating out of the pump. These HEPA
filters provide a rated 99.97% efficiency in trapping
particles > 0.3 microns.
