INITIAL SETUP 

 

  High  pressure  fluids  are  potentially  hazardous.    Energy stored in pressurized fluids can be released 

unexpectedly and with extreme force.  High pressure systems should be assembled and operated only by 
personnel who have been instructed in proper safety practices. 

To set up the MPG2 for operation, proceed as follows: 

   Set the MPG2 on a hard, flat surface.  If desired, anchor the MPG2 to a stable working surface using 

the mounting holes on the bottom of the MPG2 platform or the clamp openings on the front.  The 
mounting hole diameter is 6.4 mm (0.26 in.) suitable for M6 or 1/4 in. screws.  If mounting to a wood 
bench top, use of threaded inserts and machine screws is recommended. 

  Connect the TEST1 and/or TEST2 port to the system into which pressure is to be generated and 

controlled.  All MPG2 pressure connections are DH500 female (DH500 is a gland and collar type 
fitting for 1/4 in. (6 mm) coned and left hand threaded tube.  DH500 is equivalent to AE F250C, HIP 
HF4, etc.).  If a TEST port is not being used, plug it using the DH500 plug supplied in the MPG2 
accessories. 

 

  ALWAYS use external tubing and fittings rated for pressures equal to or greater than the maximum 

pressure which MPG2 will be used to generate. 

 

  DH500 F fittings are delivered with disposable, orange, plastic dummy plugs installed.  These are NOT 

intended to hold high pressure.  They should be removed and replaced with appropriate fittings or stainless 
steel plugs before high pressure operation.  Each dummy plug carries a DH500 collar.  Remove and retain the 
collar for use in connecting to the mating tube. 

   Fill the fluid reservoir:  Close the reservoir shutoff valve.  Remove the reservoir cover by rotating it 

CW.  Pour the desired fluid into the reservoir.  Do not overfill.  MPG2 is tested with a low viscosity, 
fluorinated liquid and should be free of significant fluid residue as delivered. 

  Prime and leak check pressurized system (see Section 3.2.1).
