Depending on the condition of the fuel and the amount of sludge build-up, it is recommended to initially
use a double dose of one to twenty-five hundred (1:2500) instead of one to five thousand (1:5000) This
has proven to be essential in accelerating the tank cleaning process. AFC-705 contains detergent,
surfactant, dispersant, corrosion inhibitor, lubricity enhancer and combustion catalyst. It does not contain
biocides. AFC-705 should always be used periodically in particular to stabilize fuel that is stored for longer
periods of time.
Note: In cases of severe tank contaminant build-up (sludge) and high water level in bottom, it
is recommended to clean the tank (vacuum bottom) and polish the fuel before initial
use of an STS system.
MAINTENANCE
! IMPORTANT ! It is recommended that only qualified, experienced personnel, familiar
with this equipment, who have read and understood all the instructions in this manual
should install, operate and maintain the system.
! IMPORTANT ! Always disconnect the system from the electric power supply before
working or servicing it. Do not proceed with any maintenance unless the pressure or
vacuum has been released, the system has been allowed to reach ambient temperature
and all fluids have been drained.
PREVENTATIVE MAINTENANCE
The STS 7030 Automatic Fuel Filtration System should be visually
inspected and tested a minimum of
every six months
according to the procedure below
during light duty cycles. Monthly inspections are
recommended for systems that are being used in excess of an average of 8 hours day and five days a week.
o
Prior to performing the maintenance procedure ensure that:
1.
The electrical sub-panel mounted main disconnect switch is operating properly,
2.
the user supplied remote circuit breaker is in the “Off” position, and
3.
All sources of power are isolated from the unit.
4.
Proceed only after this has been verified and properly tagged.
o
Drain visible water and sediment from primary filter / water separator (see Servicing Primary Filter
/ Water Separator below).
o
Check enclosure and all parts for corrosion and rust.
o
Check locking latches, door and hinge operation.
o
Check cabinet mounting hardware. Tighten as necessary.
o
Check pump/motor hardware for tightness. Pump/motor hardware will loosen after normal
operation due to vibration. This hardware is lock nutted, check all bolts for secure nuts.
o
Check all electrical terminals and connections for tightness.
o
All motors are permanently lubricated and do not require any lubrication.
o
All pumps are self-lubricating and do not require any maintenance.
o
Check all plumbing joints for leaks. Tighten fittings and joints as necessary. Remove accumulated
fuel in drip tray as necessary.
o
Inspect all filters and separators. See section below on filter inspection and service.
o
With breakers and power turned on again and pump running
check all alarms
for proper operation:
1.
Manually raise float switch located in drip/spill tray. Pump should immediately turn off and
“LEAK DETECTION” should illuminate. Reset alarm by pushing the “RESET ALARM” button on
the control panel.
2.
Slowly partially close inlet ball valve. At 12”HG pump should turn off and “HIGH VACUUM
ALARM” should illuminate. Open inlet ball valve again. Reset alarm by pushing the “RESET
ALARM” button.
