ROLA-CHEM Digital Controller PN 554135 12/26/18 Page: 14 of 24
NSF certification of this automated controller requires the use of a flow switch. To install a
flow switch, remove the jumper and install the flow switch leads. Note: With the flow switch
installed and the jumper removed, the flow light will no longer operate as a power light. It is
recommended the jumper be retained to assist in troubleshooting if necessary.
4.3.4 Globe Flowcell
(see Globe Flowcell Operating Manual)
Connect the Globe Flowcell grounding stud to ground in order to prevent erroneous readings
and to prevent damage to the probes.
Note: It is recommended that an inline filter be used to help keep the
Globe Flowcell (including probes) and flow switch free from debris. Debris may cause
obstruction in flow switch and prevent the switch from functioning.
