All system valves can be tested using the
Valve Control
menu (Figure 17). This
menu allows the user to actuate the
Pressure Valve, Vent Valve, and Vacuum
Valve.
When the valve is actuated the user will hear the valve switch. If the
valve switch is not audible then contact the Wasson-ECE service department for
support at (970) 221-9179.

The
Leak Test
menu (Figure 18) allows the user to check that the system is leak
tight. If the system is not leak tight achieving lower vacuum will be difficult if not
impossible. From the
Diagnostics
menu select
Leak Test.
Using the arrows
choose a desired charge pressure and a soak time. If the system holds pressure
to +/- 0.4 psi the system is considered leak tight and will pass the test. If the
system fails the leak test secure all fittings and run the leak test again. The
status of the leak test is displayed in the
Leak Test
menu.
The leak test feature can also be used to ensure the canisters have been
attached properly and that none of the canister fittings are loose before cleaning.
