With the valve closed, make sure the trip rod is pushed fully into its sleeve, then lock the trip rod in this position by tightening the thumbscrew in the clutch top.
Slide Valve Thief: Open the valve by pulling it outward until the clutch pin holds it open. Internal Valve Thief: Open the valve by pushing the lever down until the cock pin holds it open.
Put the bail assembly hook into the slot at the top of the trip rod sleeve.
Slowly lower the oil thief to the desired level in the tank.
Give the lowering line an abrupt upward jerk. This should trip the valve closed, making the sample ready for retrieval from the tank.
TANK BOTTOM BUMP CLOSURE
Set the trip rod so its bottom end is at least 1/4 inch below bottom of oil thief, or extended to the desired sample height from bottom of tank.
Slide Valve Thief:Lock the trip rod securely in set position by tightening the thumbscrew in the clutch top. Internal Valve Thief:Lock the trip rod securely in set position by tightening the thumbscrew in the valve cock.
Open the valve.
Lower the oil thief in a continuous motion until it bumps the tank bottom and trips the valve closed. Sample is now ready for retrieval.
*All repairs must be sent back to factory for warranty to remain effective.
Mount the unit in position so that the float mechanism moves vertically and is at an elevation above the pump priming port.
Use noncollapsible hose to connect the unit OUT port to the vacuum source, for example a tee fitting spliced into the vacuum line.
Use noncollapsible hose to connect the unit IN port to the pump priming port, with the provided ball valve in between.
Close the priming line ball valve.
Close the pump discharge valve to prevent air being drawn through the discharge.
Start the vacuum source.
Open the priming line ball valve.
When water enters unit, close priming line ball valve. (Water entering unit indicates pump is primed.)
Start the pump and open the pump discharge valve.
Stop the vacuum source then allow the water to drain from the unit
*NOTE: If water does not flow from discharge, turn your pump OFF and repeat steps 2 through 5. When pump is discharging properly the priming line may be disconnected from primer and the engine providing vacuum turned OFF.
Chamber housing should be kept clean in order to observe the float valve.
*If necessary, remove the unit and flush with water or a mild soap solution. *Do not use any harsh cleanser or chemicals to clean the unit.
Use only soap and water to clean plastic parts.
Do not tighten tie bolts or plastic dome more than necessary to provide seal.
Keep the priming line ball valve closed when manifold primer/water trap not in use.
