WARNING
Check that the seals in the test connections are seated correctly and are not worn.
Replace them if necessary.
It is important that any instrument that is to be connected is clean inside.
Information
As standard, the test connections are G ½ female.
5.4.2
Filling the base unit with liquid
1.
Remove filler plug from reservoir by prising plug out. (This plug should be left out whilst in use).
2.
Open valves A and B.
3.
Wind spindle pump handle fully clockwise.
4.
Fill reservoir with appropriate liquid. Use the oil supplied or an approved substitute for oil
systems. Do not use other liquids. Castor based oils, Skydrol, solvents or similar liquids will
attack the seals fitted in the test pump.
5.
Wind spindle pump handle fully anti-clockwise.
6.
Top up reservoir if necessary.
Wear safety goggles!
Protect eyes from flying particles and liquid splashes.
5.4.3
Post assembly test
1.
Carry out a test calibration of a known instrument (see chapter 5.5 “Procedure”) to ensure that
the unit is working correctly.
2.
Release the pressure and remove the test instrument.
Information
To remove the instrument from the system, use the appropriate size of spanners on
the top section of the pressure connection and on the body of the instrument only.
Ensure that the lower part of the pressure connection is not rotated as this may
release it from the base.
3.
The system is now ready for use.
Information
When testing equipment with a large volume, the capacity of the spindle pump (65
cm³) may be insufficient to reach the pressure required. In this case, the equipment
should be filled as far as possible with the liquid before connecting it to the system,
so that the displacement needed is reduced.
Dirty or chemically contaminated test items should not be fitted as they contaminate
the system unless they are first cleaned.
