a. Because of the variety of installation arrangements possible with
the PWS/DS, there is no single sequence of procedures for shutdown of the
system. It is recommended, however, that as much water be removed from the
system as possible while it is still intact. This involves using the 125-
GPM pump to drain the storage tanks to remove as much water as possible
before the pumps are disconnected.
If the water is to be discarded, the
hypochlorination unit can be disconnected before water is pumped from the
storage tank. Unused chlorine solution should be considered hazardous waste
and properly disposed.
b. Disassemble the system in reverse order of assembly.
Perform the
following steps prior to repacking: Drain, dry, and then cap and plug all
hose assemblies. Drain and dry all metal assemblies, such as valves and tee
assemblies. Cap and plug these items, as applicable. Remove and retain the
two quick-disconnect elbows from the suction and discharge side port nipples
on the top of each of the collapsible tanks. Then attach a protective cap
to each of these nipples. Drain each tank by turning the gate wheel on the
drain hose assembly which is attached to the drain fitting in the tank
bottom. Then, remove the drain hose assembly and thread the protective plug
into the tank drain fitting. Collapse, fold, and repack the tank into its
container.
