6. Start the pump unit (Page 0006 00-1). Open VALVE NO. 1 for this operation. Remove the hopper tank lid.
CAUTION
Cycle water containing M2 antiset for at least 3 minutes. The M2 antiset must be completely dissolved.
NOTE
If the M2 antiset is caked, it must be crushed as finely as possible before adding it to the water in the tank
unit assembly.
7. Add the M2 antiset and silicone antifoam agent. Operate for 3 minutes to fully blend these additives.
8. To prepare STB decontaminating agent for loading, open the 26 cans of STB decontaminating agent (Page 0028 00-2,
item 8).
NOTE
Before starting the loading and blending operations, break up the large lumps of STB to prevent clogging
of the lines and to ensure the best possible water-slurry mixture. To prevent damage to the equipment, do
not strike the metal drums containing the STB decontaminating agent against the tank or any other part of
the tank unit.
9. Add the 1,300 pounds of STB decontaminating agent (Page 0028 00-2, item 8) in one continuous operation. When
loading agent, see that hopper does not run out of STB decontaminating agent. If the supply of agent is exhausted before
loading is completed, the slurry in the tank may foam. Stop foaming by adding additional silicone antifoam agent.
CAUTION
After the slurry is blended, it must be agitated constantly until used.
10. After blending is complete, replace tank lid. Agitate the slurry mixture.
