Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as splashing
fluid, follow the Pressure Relief Procedure when
instructed.
1.
Close the abrasive ball valve (M).
2.
Close the compressor supply air valve, then turn
the compressor off.
3.
Engage the blast control switch (B) to relieve
pressure in the system.
4.
Verify that the supply pressure gauge (ZC) reads
0 psi. Then disconnect the air inlet hose from the
system.
5.
Turn the selector valve (W) to OFF.
6.
Open the pot dump valve (J) until the pot
pressure gauge (L) reads 0 psi.

grounding continuity. Check the electrical resistance
of the blast hoses. If the total resistance to ground
exceeds 29 megaohms, replace the blast hose
immediately.
