About Your Environmental Express AutoBlock
®
Fill Station
AutoBlock® Fill provides a safe, efficient method of adding digestion reagents to water, wastewater, soil, and sludge samples
for metals analysis. The station works with any size of HotBlock®, HotBlock® Pro, and HotBlock® 200 metals digestion systems
to automate the most dangerous step of metals digestion—the reagent addition.
The station dispenses independently from up to five reagent bottles. No need to swap out reagent bottles when switching
digestion methods—a five-way valve setup provides easy switching between reagents. The reagents are dispensed by an
integrated Masterflex® peristaltic pump accurate to ±2% volume (calibratable to any dispensing volume).
The AutoBlock® Fill can be programmed and controlled via the onboard touch screen or use the included software to connect
directly to a computer. The station features preprogrammed EPA methods or the user can create customized programs.
Users should be aware of potential dangers from heating certain types of compounds. Such hazards may include explosion or
the release of toxic or flammable gases. The AutoBlock® Fill is designed to fit in a fume hood.

Installation of your AutoBlock® Fill Station
1. The AutoBlock® Fill requires some assembly prior to operation. A video showing how to perform the assembly is located
on the
AutoBlock® Fill product page
.
2. The top section of foam packaging contains the horizontal brace, the HotBlock® rails, and the vertical brace. The
bottom section of foam packaging contains the tower, base plate, XY arm assembly, and power cord and tubing. A bag
of hardware to connect all the pieces together is also included.
3. Attach the tower to the base plate. Set the base plate on a secure flat surface with the cam lock lever on the left side.
This will orient the base with the attached brace rail to the right, the wider track slot in the front, and the narrower
track slot towards the back. The far-right side will have an outline of the tower with six screw holes. The tower should
be oriented with the peristaltic pump to the front, the drain trench on the left, and the five-way valve on the right. Use
six (6) #0.25-20 x 0.75 Phillips head screws. This step and the next one are best accomplished by laying the tower on its
back and having the bottom panel facing you.
4. Attach the vertical brace to the bottom panel at the left rear corner. The rounded end will be up in the air and the flat
end will be attached to the panel. The notched side will be at the bottom facing the rear. Use two (2) #0.25-20 x 0.75
Phillips head screws.
5. Remove the side panel from the right side of the tower. You will need a Phillips head screwdriver to remove the screws.
Be sure to note which screws came from which holes. The shorter screws must go back in their specific holes to assure
proper fit. Set the panel aside.
