SET-UP AND MAINTENANCE
Set-up and First Use
1 . Unpack the Shop Pro ST and remove cable ties from
hoses .
2 . Remove the vent cap from the filtration unit .
3 . Pour diesel fuel into the clear cover until it reaches the
black band on the filter element . (This fuel will be on
the “dirty” side of the filter, meaning that the fuel will be
filtered before flowing through the Shop Pro ST to the
engine or tank .)
4 . Reinstall the vent cap and tighten by hand until it clicks .
The Shop Pro ST is now ready for use .
5 . Connect the Shop Pro to a power source . Install the
pick-up wand (green hose) and dispensing wand (red
hose) . Put the wands in a five gallon (minimum) fuel
container or truck fuel tank . Turn the Shop Pro power on
and circulate fuel until there are no bubbles in the sight
tube . Turn off the Shop Pro . Close the ball valves on both
hoses . Remove the wands from the hoses and return
them to their storage area . Connect the hoses to the hose
retainers . (Refer to photo on page 2 .)
Filtration Unit Maintenance
Drain Water
Water that has been separated from fuel will collect in the
bottom of the body of the filtration unit . Drain the water
periodically . The frequency will depend on how often the
Shop Pro is used and the quality of the fuel it has filtered .
1 . Open the vent cap slightly to break the vacuum . Place the
end of the drain hose in a suitable container and open the
drain valve .
2 . When only fuel is coming out of the hose, shut the valve .
Hand tighten the vent cap until it clicks .
Filter Replacement
Replace the filter in the filtration unit when there is low flow/
pressure or when the filter is visibly contaminated . The filter
change will also include replacement of the seals on the vent
cap and on the collar .
1 . Remove the vent cap and open the drain valve to drain
the fuel below the collar level . Close the drain valve .
2 . Remove the collar (use the DAVCO wrench) then remove
the clear cover . Remove the filter . Remove the seals from
the cover and the vent cap . Dispose of the filter and the
seals properly .
3 . Using a clean shop rag, clean the cover, vent cap, collar
and threads on the filtration unit body . Do not use any
acetone based cleaners on the clear cover .
4 . Install the new filter and the seals (included with the
replacement filter) .
