Helpful Hints Continued
Extension Cords and Low Voltage
Vacuum pumps will work best when the voltage at the machine (while it is running) is between
115 and 122 volts.
Check that the voltage coming from the source outlet is adequate. Please note that the circuit
could have many other items on it e.g. light fixtures, appliances, or other motors. All of these extra
loads on the circuit will cause a lower voltage and reduced performance.
Likewise, long and thin extension cords also starve the motor of necessary voltage and can cause
very dangerous overheating of the motor and extension cord. Extension cords should be at least
12AWG and not longer than 15 ft.

Care and Maintenance
Cleaning the Input Debris Screen
The TEZ8 is equipped with a clear monitor tube located in the right-front corner of the machine
which allows you to observe the incoming airflow for debris, oil, or any other material which could
damage the pump.
A small filter screen is located in the fitting at the top of this monitor tube to prevent large debris
from entering the pump and causing damage. For best results, this screen should be cleaned
regularly.
Open the door located on the right side of the ma
-
chine to access the clear monitor tube.
Grab the monitor tube and pull it straight down to
release it from the input fitting, then remove it from
the machine. (Fig. 1)
Remove the screen from the input fitting, clean it
thoroughly and place it back into the fitting. If the
screen is damaged, it should be replaced. (Fig.

Connect the monitor tube back up to the pump with
the tube opening facing towards the top. Make sure
that the spring is pushing against the bottom of the
