TekStak™ MANUAL AND REFERENCE INFORMATION

In addition to the included components listed, the items listed below are necessary in order to assemble the stack. These items are not included, except where noted.

Flow Ports ≥Required for Assembly

1. Insert 4 of the O-rings into the 4 O-ring grooves on the underside of each plastic endplate. Next gently press the 2 current collector plates into the recessed pockets on the plastic endplates. When pressing the current collector plate into place, it is important that the plate be inserted into the recessed pocket properly. The tab on the current collector should extend beyond the plastic endplate on the same side as ports 2 and 3. The tab should be closest to port 2. If the current collector plate is misaligned, the stack will leak when assembled, resulting in a potentially hazardous situation and poor stack performance.

2. One plastic endplate has nuts pressed into the bolt holes. Take this plate and lay it flat on the table so the Parker logo faces down.

3. Insert the 4 -1/8”-diameter plastic assembly dowels into the flow ports of the plastic endplate. The flow ports are the small diameter ports located within the O-ring grooves.

10. The stack assembly will be completed by positioning the second plastic endplate and using the stack bolts to fasten the stack together. Begin by properly aligning the plastic endplates. If the plastic endplates are aligned correctly, the current collector tabs should protrude from the same side of the stack and both tabs should be visible when looking at the stack from above. This ensures that both current collectors are properly seated in the plastic endplate and that the flow ports are in the correct positions. For a visual example of proper alignment, refer to the image of the assembled stack included at the end of this manual. This image shows how the current collector plates will line up when the stack has been assembled properly. Next, carefully remove the 4 assembly dowels from the stack as necessary to slide the plastic endplate into place. After positioning the endplate, reinsert the dowels through the two open ports (ports 3 and 4).
