4 The DynaPak 2000 Pump is adjustable from 0 to .4 cc/stroke. The pump is actuated by pipeline gas which passesthrough a filter/regulator and to a 12 VDC solenoid. Thesolenoid strokes the pump each time it is energized by Theory of OperationDP-2000 Version 09092002YZ Systems , Inc. 3101 Pollok Drive Conroe, Texas USA 77303 P: F: The Sampler should be a minimum of five pipediameters from any device which could cause aerosols orsignificant pressure The Sampler should not be located within the definedmeter tube region (AGA 3-1985 ED.).A = The number of unobstructed, straight pipe diametersupstream (see AGA - 3 manual).

The positive lead connects tothe red wire and the negative lead connects to the Before applying pipeline pressure to the DynaPak 2000,ensure that the isolation valve and purge valve are After pipeline pressure has been applied to the Sampler ,check the probe body/pipeline connection using a liquidleak 1/4" stainless steel tubing must be connected from asource of supply actuation gas with a minimum pressure of65 psig to the external gas supply connection for the FilterRegulator located on the left side of the Sampler .

6 Incorrect operation of valves (over tightening)can result in damage to the valve components(isolation valve bonnet assembly) which mightresult in the valve stem being screwed out of theprobe body. This of course results in product atpipeline pressure being vented continuallythrough this port until this section of the pipelineis shut in. Be aware of the following proceduresand information. DynaPak valves are of soft seatdesign and should only be closedor opened with fingers. Nowrenches should ever be used. If a valve will not seal off withfinger tight operation the valveshould have maintenanceperformed to allow properoperation of the System InstallationCenter 1/31/31/31/3 Center 1/31/31/31/3 ExternalGas SupplyConnectionDP-2000 Version 09092002YZ Systems , Inc.
