7. Turn power on to console to test sensor.
8. Test sensor (verify that an alarm is produced at
ATG console), if it does produce an alarm, seal
EYS seal fittings and electrical connectors with
epoxy.
9. Turn power off again if other devices are to be
installed (Repeat Step 3).
10. Install the TSP-MWS sensor in the well screen
pipe and latch the riser cap (ref. Figure 1 & 2).

11. Reinstall all safety covers and guards, junction
box gasket and covers – use pipe-dope to seal all
fitting threads.
12. Install the manhole cover.
13. Record the location where the sensor was
installed (Tank #,Sensor Channel #, and other
data) on the table on the back page of these
instructions.
14. Turn power on and program the ATG – Refer
to Sensors in the ATG Setup / Programming &
Installation manuals.
General Installation Notes
It is the installer’s responsibility to
comply with all applicable federal, state
and local codes. Failure to do so may
create an Environmental Hazard.
Plan your conduit routing. Dig trenches as necessary to
install conduit from each junction box to the Intrinsically
Safe (I.S.) knockouts at the ATG console. You must install
a weatherproof, electrical junction box inside each sump.
Access to sumps must be done so all entries are liquid-
proof (to keep product in the sump if a spill or leak occurs).
The junction box should be installed high on the sidewall to
prevent it from being submerged during heavy rains.
A junction box may be used inside of the building and used
as a I.S. pull box to combine several sensor cables. If this
is done, then only one I.S. conduit knockout may be used
at the console. Before pulling wires, mark them to avoid
confusion when connecting to the console.
Conduits must have EYS seal fittings
installed in accordance with NFPA
70 (National Electric Code) and NFPA
30A (Automotive and Marine Service
Station Code). Failure to seal conduits
in accordance with NFPA 30A, and
NFPA 70 could allow flammable vapors
to travel through the conduit in the
ATG console. An explosion could result
causing serious injury, property loss,
or death.
CAUTION Seal all threaded fittings and conduit threads to
produce a weatherproof seal during installation.
