INSTALLATION, OPERATION, AND MAINTENANCE

Planning the Installation

Location
1. Location — locate the day tank as close as practical to the engine generator.
2. Accessibility — the day tank should be located where it is accessible for inspection,
maintenance, and repair.
Piping
efore starting layout and installation of your piping system, consider the following points:
1. Size the fuel supply piping to minimize frictional head loss based on the design flow.
2. Size gravity overflow piping to assure adequate flow capacity. It should be at least one size
larger than the inlet piping of the day tank – for a single day tank installation. Where
multiple day tanks share a return flow line, the line should be adequately sized and sloped
to assure required capacity.
3. Install gravity overflow pipe so that it slopes continuously from the day tank back to the
main storage tank.
4. Be sure the inside of the pipe is clean before connecting to the day tank.
5. Be sure allowance is made for expansion and contraction of the piping so the day tank
connections are not stressed by the piping.
6. The day tank should not be used to support the piping. The weight of the pipe should be
carried by hangers and supports.
7. When fastening the piping to the day tank it should not be necessary to impose any
strain on the day tank fittings. Do not use the day tank to correct errors in piping layout
or assembly.
8. All joints of the piping system should be tight; pipe sealer will help assure leak-free
threaded joints.
9. Provide a pressure relief device in any part of a pump and piping system that can be valved
off and, thus, completely isolated. The rise in temperature causes the liquid to expand; if
there is no provision for pressure relief in the closed off section, there is a chance that the
pump or piping will rupture.
