2. Disconnect the tubing at the blast check valve (L)
and at the ll port check valve (ZG).
3. Make sure the bung is engaged with its seal.
Turn the selector valve to WASH, then open the
abrasive ball valve to pressurize the pot. Set the
pot pressure to 145 psi (9.9 Bar, 0.99 MPa).
4. Check the water pump to conrm that no water
is leaking from the TSL ll port.
NOTE:NOTE:
NOTE:
The pump should stall after the pot
pressurizes. If the pump does not stall, replace
the seals. Refer to the pump manual for repair
information.
5. Check for any water leaking from either check
valve. If a check valve is leaking, it must be
repaired or replaced. If the valves are damaged,
the pot will not be able to maintain pressure.
Also, check the pot pressure relief valve. If the
valve is weeping at pot pressures of 145 psi or
less, it needs to be replaced.
6. Close the abrasive ball valve , then disconnect
the quick coupler and conrm that the ball valve
is not leaking. Replace the abrasive ball valve
if it is leaking.
