Section X – Start-up and Test
A. Start-up
Start the system and sequence the unit through all
positions while watching for appropriate movement of
actuators. Improper or erratic movement of the actuators
may indicate incorrect assembly of the unit or presence of
trapped air.
B. Test
A test stand having regulated flow, temperature control and
special fixtures is required to fully test the performance of
the rebuilt unit. Because of this, only the functional test
shown in the start-up paragraph is given. If such a test
stand is available, test the unit to the requirements set forth
in the installation drawings.
