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 MPG1 for operation, proceed as follows:
Anchor the MPG1 to a stable working surface using the mounting holes on the bottom of the MPG1
platform. The mounting hole diameter is 6.6 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 MPG1 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 a DH500 plug supplied in the MPG1
accessories.
ALWAYS use external tubing and fittings rated for pressures equal to or greater than the maximum
pressure which MPG1 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 ISOLATION valve. Remove the reservoir cover by
lifting it off gently. Pour the desired fluid into the reservoir. Do not overfill. MPG1 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).
