GENERAL
UNPACKING
Inspect the box and pump carefully for any signs of damage incurred in transit and report with-in 7 days of receipt.
Since all our pumps are shipped F.O.B. our factory, such damage is the responsibility of the carrier and reported to
them. The inlet & exhaust of the pumps are covered with plastic caps to prevent dirt and other foreign substances
from entering the pump. Leave the caps in place until you are ready to pipe the pump to your equipment.
LOCATION
Install the pump in a horizontal position on a level surface so that the pump is evenly supported on it’s rubber feet.
Leave 12-18” of access around the pump to allow proper cooling. Allow access to the oil sight glass in order to in-
spect the oil level, and the exhaust port for easy access to change the filters.
DO NOT TIP THE PUMP OVER IF FILLED WITH OIL
POWER REQUIREMENTS
A schematic diagram for the electric motor terminal box is located either inside the junction box cover or on the side
of the motor itself. The motor must be connected according to applicable electrical codes
Through a fused switch in order to protect the motor against electrical or mechanical overload conditions. The over-
load of the motor starter must be set at a level equal to the full load motor current listed on the nameplate.
AFTER ELECRICAL CONNECTIONS HAVE BEEN MADE, BUT PRIOR TO FILLING THE PUMP WITH OIL, THE
ROTATION OF THE MOTOR SHOULD BE CHECKED. IF BACKWARD, REVERSE ANY TWO LEADS OF THE
THREE AT THE POWER CONNECTION
VACUUM CONNECTION
Use a pipe size that is at least the size of the pump inlet connections. Smaller lines result in reduced pump capacity.
Pumps operating in parallel on a common main line should have a manual or automatic shut-off valve or positive
acting check valve installed in the suction line of the pump. The pump built-in anti-suckback valve should not be
Used as a shut-off valve for the vacuum system.
Should the process gas contain dust of other foreign material, a suitable inline particulate filter should be connected
to the inlet port…..contact US Vacuum for recommendations.
The vacuum piping should be designed to insure that no liquids such as condensate or liquid carryover from the
process can reach the pump. If this possibility exists, a knock-out liquid separator should be installed…..contact
US Vacuum for recommendations.
If an exhaust manifold is used, install a drip leg near the pump exhaust port and drain to prevent exhaust conden-
sate from entering the pump exhaust box.
DISCHARGE CONNECTION
DO NOT RESTRICT PUMP DISCHARGE. The TV series of pumps all come with integral oil mist filters for
Oil free discharge. Access to the filters are thru the threaded discharge connection.
Do not restrict the discharge on the pump being this will generate internal pressure inside the pump and damage or
bodily injury may occur.
