Installation and Operations Manual
17
H Check wire size and length. Incorrectly sized wires can cause voltage drop at the pump. If temperature of wire is high,
use larger wire size.
I Check to see if motor turns.
J Pump or motor may be seized. Contact the factory.
K Check rotation. Rotation should be clock-wise when facing back end of motor.
L Check oil. If oil is varnished, replace at once. Check hour meter. Oil should be replaced as specified in the Installation
and Operations manual of the pump.
M Check vacuum pump gauge. Gauge may be faulty.
N Check oil level. Oil level should be maintained at the middle of the top sight glass on the side of the pump reservoir.
(Check when pump is off and is stationary).
O Check to see if the inlet to the pump is wide open.
P Check coupling between pump and motor. If damaged, replace. In an inlet filter is installed, check to see if
filter element needs to be replaced. Note: The rotary vane vacuum pump models PVL200-PVL540 have built
in inlet filters.
Q Check backpressure on pump. Exhaust element may need to be replaced. Refer to Installation and Operation manual
For maximum pressure and replacement instructions.
R Check oil for foaming. If foaming, replace.
S Make sure that pump is being cooled correctly. Check that pump is located in a well-ventilated area. Maximum
ambient temperature for the rotary vane vacuum pumps is 100 deg. F. All standard pumps are air-cooled. Inspect fan
for damage. Clean motor and pump air grills if needed.
T Check to see if the oil is contaminated. If the oil has been used longer than the recommended life expectancy, the
pump will not draw ultimate vacuum. Allow pump to cool before changing oil.
U Check to see I system is holding vacuum. This can be done by shutting the pump system down and observing over
time if the gauge on the receiver is holding. If vacuum is not holding, check all pipe connections for leaks using
conventional leak detection methods.
V Check to see if inlet screen on pump is plugged. If plugged, clean wire screen and reinstall. If an inlet filter has not
been installed, and the problem persists, install an air filter. Refer to Installation and Operation manual. Note that the
rotary vane vacuum pumps models PVL200-PVL540 have build in inlet filters.
W Check to see if inlet valve assembly is stuck in closed position from contamination. Disassemble and clean inlet valve
and screen as required. Refer to Installation and Operations manual.
X Check around pump for oil leaks. Oil tubing may be damaged or defective. Replace and/or tighten fittings as needed.
Y Internal parts may be worn or damaged. Contact factory.
Z Check pump model. The PVLB design will not achieve the same ultimate vacuum as the PVL.
AA Check power supply. Excessively high or low voltage will damage motor.
BB Check to see if pump is overfilled with oil. Oil level should be up to the middle of the top sight glass on the side of the
pump reservoir. (Check when pump is off and is stationary).
CC Check oil. Oil may be too heavy (high viscosity) or the ambient temperature is below 5 deg. C (41 deg. F). If oil is too
heavy. Refer to the Installation and Operations manual and replace the oil with Travaini’s recommended oil.
DD Foreign particles may have carried over into pump causing damage to the vanes or other internal parts. Contact the
factory.
EE Check operating temperature. Excessive heat will cause smoking.
FF Check internal exhaust element. Exhaust element may not be seated correctly with o-ring.
GG Check anti-suckback valve. Valve may be clogged or may be functioning incorrectly. Refer to exploded view in
Installation and Operations manual for position of check valve.
