•
The chemical pump shutoff valve can be
turned on for cleaning operations at 1,200
psi or lower.
The chemical pump shutoff valve is on when
the handle of the integrated valve is in line
with the pump (see figure 4-4).
To protect the heat exchange system,
the TMT 3000 is designed to open
the pressure relief valve if the system
registers more than 2,500 psi.
Turn the chemical pump shutoff valve
