NOTICE - Recovery Pump
! !
When using aquastat as pump control in storage tank recovery application, temperature detection may be
insensitive if the aquastat is positioned in a immersion well or sits on the pipe. It is important to check against
eternal's inlet temperature by using eternal's diagnostic function to verify that the pump does shut off when "I"
reached 20
° F below the setting temperature and aquastat is setup properly.
WARNING - Aquastat
