C OMPONENT D ESCRIPTION
Auto-Cooling Valve Keeps the hydraulic fluid clean and cool by circulating the fluid through the
return filter and the heat exchanger while the HPU is in high pressure mode
and the fluid demand by the external circuit is very low.
Control Panel Controls the operation of the power unit and indicates the current status of
several detectors.
Electrical Enclosure Houses the electrical and control components of the HPU. The main power
lines enter the unit at the top. The power disconnect switch removes electrical
power whenever the enclosure door is opened.
Filler Cap Vents the hydraulic fluid reservoir. This is where you add hydraulic fluid.
Filter Filters particles out of the hydraulic fluid as it is returned to the HPU.
