a. Position the tackle supports on the front and rear top of the tunnel, securing each with the four hexagon
Figure 2-2. Installing tackle supports.
b. Thread a rope through each pulley wheel of the swivel eyes and tie one end of each to eyebolt on tunnel
c. With a suitable hoist and a four-point sling attached to lifting eyes of tunnel, lift the tunnel into position
over the storage tank. Align the tunnel so that the support rails (channels) on bottom of tunnel are directly over
the tunnel support beams and lower the tunnel onto the beams. Center the tunnel between the sides of the
d. Install the six-piece rain shield around base of tunnel as shown in figure 2-3. The rear rain shield must be
installed first, then the side rain shields, working from the rear forward, with the front rain shield installed last.
e. Open the front doors of tunnel and fold out the loading platforms. Support legs of platforms must rest on
the front stand-off guard.
f. Install the rear discharge chute (41, Figure 6-4) by hooking over the support angle welded to tunnel, just
below the discharge door frames. The outer edge of the discharge chute will rest on the rear standoff guard.
g. Install thermometer (1, Figure 6-4) by threading into opening in front wall of storage tank.
h. Install heat transfer piping and asphalt jacketed valve as shown in figure 6-1. Insure that gaskets at each
flanged coupling are not damaged or folded in such a way that would hinder sealing the joints.
Install flange joint hexagon head capscrews and nuts finger tight, until all
connections have been made then tighten all hardware securely.
i. For operation as a single unit installation, install connecting heat transfer piping and asphalt discharge
j. For installations of multiple units make interconnections of heat transfer piping and asphalt hoses as shown
k. Inspect all connections to insure that they are tight and that the storage tank drain cap, in rear of storage
tank, is installed.
l. Connect the heat transfer piping to the heat source at the 2-/2 inch reducer coupling on the ends of
m. Connect the asphalt discharge hose to supplied pumping unit for transfer of melted asphalt to working
