INTRODUCTION
CONGRATULATIONS on your purchase of a new KINNEY®KVA or KVAH oil lubricated, rotary vane vacuum pump from Tuthill
Vacuum & Blower Systems. Please examine the pump for shipping damage, and if any damage is found, report it immediately to the
carrier. If the pump is to be installed at a later date, make sure it is stored in a clean, dry location and rotated regularly. Make sure
covers are kept on all openings. If pump is stored outdoors be sure to protect it from weather and corrosion.
KINNEY KVA/KVAH vacuum pumps are built to exacting standards and if properly installed and maintained will provide many years
of reliable service. We urge you to take time to read and follow every step of these instructions when installing and maintaining your
pump. We have tried to make these instructions as straightforward as possible. We realize that getting any new piece of equipment
up and running in as little time as possible is imperative to production.
This manual is written to cover KVA and KVAH Model vacuum pumps. Please identify the model number and serial number when
ordering parts.
WARNING: Serious injury can result from operating or repairing this machine without first reading the service
manual and taking adequate safety precautions.
IMPORTANT: Record the model and serial numbers of your pump in the OPERATING DATA form on the inside back cover
of this manual. You will save time and expense by including this reference identification on any replacement part orders,
or if you require service or application assistance.
INSTALLATION
UNPACKING
Inspect the box and pump carefully for any signs of damage incurred in transit. Since all pumps are ordinarily shipped F.O.B. from our
factory or regional warehouse, such damage is the normal responsibility of the carrier and should be reported to them.
The vacuum pump is bolted to the skid, and the fasteners must be removed to free the pump.
The inlet and exhaust of the pump are covered with plastic caps to prevent dirt and other foreign substances from entering the pump.
Leave these 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 its rubber feet. Leave 12-18” of
access around the pump to allow proper cooling. Adequate ventilation must be provided for the fans, radiator, and motor.
Allow access to the oil sight glass in order to inspect the oil level, and the exhaust port for easy access to change the exhaust filters.
Do not tip the pump over if filled with oil.
POWER REQUIREMENTS
A schematic diagram for the electrical motor terminal connections is located in the junction box of the motor or on the motor
nameplate.
The motor must be connected according to the electrical codes through a fused switch in order to protect the motor against electrical
or mechanical overload conditions. The overload of the motor starter must be set at a level equal to the full load motor current listed
on the motor nameplate.
If the pump is supplied with a motor starter, it is preset at the factory according to customer specifications. It is advisable to check that
these settings are in line with the voltage at your location. If the voltage is different, please contact Tuthill Vacuum & Blower Systems
for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counter clockwise when looking at the motor from
the motor’s fan side.
NOTE: After electrical connections have been made, but prior to filling with oil, the rotation of the motor should be checked.
If backward, reverse any two leads of the three at the power connection.
