The tank comes unfilled; please fill with the proper fluid as described earlier in this document.
• Fluid Cap: The cap has a 5PSI check valve to prevent moisture from entering the tank
• Fluid Level Sensor: Detects the hydraulic oil level in the tank. When fluid level is too low, the sensor will send a signal
to the DCC
• Main Electrical Feed: Supply 208/230/460 power supply from your Motor Starter Panel
• 20HP Motor: Capable of turning the pump to deliver 30 gallons of hydraulic oil per minute
• Pressure Adjustment Control: Regulates overall pressure distribution to the system
• Snubber Knob: Must be open to check and/or set the system, then closed
• Feed Pressure Gauge: Displays overall oil pressure being sent out to the system
• Return Pressure Gauge: Displays differential pressure across filter. Red indicates the need to change the oil filter
• Fluid Feed Manifold: Here you can make adjustments to the individual flow controls for speed adjustment
• Fluid Return Manifold: All return lines connect here
• Oil Filter: Oil filter used to cleanse the oil before it gets back into the tank
• Site Gauge: Visually displays fluid level in the tank as well as the oil temperature
• Drain Plug: Drain oil here for maintenance
• Hydraulic Tank: 60 gallon steel tank
