START-UP
Check rotation of the motor as described in Power
Requirements on page 4
. Fill the pump with
oil as described in Filling the Pump With Oil on
page 5 .
Start the pump with the inlet closed. Run the pump
for a few minutes and then shut it down. Check
the oil level again and make sure the oil level is
between the 3/4 mark and the FULL mark on the
upper oil sight glass.
Add oil, if necessary. Add pump oil only when the
pump is off and circulating oil has sufficient time to
return to the oil sump.
STOPPING THE PUMP
To stop the pump, turn off the power. A built-in anti-
suckback valve will prevent oil in the oil reservoir
from being sucked back into the cylinder after the
pump is shut down. Do not use the anti-suckback
valve as a check valve. Consult Tuthill Vacuum &
Blower Systems for proper check valves.
GAS BALLAST
KVA pumps are equipped with a gas ballast. The
gas ballast valve is located between the inlet port
and the exhaust box. Its main function is to prevent
water vapor from condensing in the pump, which
causes emulsification of the oil that can result in
pump failure.
In applications when the quantity of water vapor
is moderate, Tuthill Vacuum & Blower Systems
recommends running the pump for 10 minutes to
its normal operating temperature prior to going on
process. Also operate the pump off process for
10 minutes prior to shutdown. A slight air bleed
(purge) is recommended during these 10-minute
cycles to prevent the vapor from condensing in the
pump.
