1. A wall-mounted, fused disconnect sized for the unit must be provided
and fitted by the client/contractor, if a disconnect is not supplied on the
panel.
2. Fuses must be sized according to motor name plates and local electrical
codes.
3. Heaters and single skid systems are generally shipped completely
prewired. The liquid level switch on the expansion tank, when supplied,
will be shipped in the parts box and must be installed in the field. Multiple
skid systems may require wiring between the skids.
4. If the unit is not skid-mounted at the factory, the client/contractor is
required to wire the circulating pump starter.
5. When using a SCR, a Shunt Trip Breaker is required to be installed by
the customer. It will be used to remove power to the panel in the event of
an over temperature/pressure condition. The Shunt Trip Coil needs to be
wired to the boiler electrical panel as indicated on the electrical drawing.
Note
If the circulating pump motor is not supplied by Fulton Thermal Corporation, the
motor starter will not be supplied.
o) Voltage & Frequency
1. Normal supply will be 460 volts, 3 phase, 60 Hz, AC unless otherwise
specified.
2. Make sure the information on the electrical drawing corresponds to your
voltage and frequency. Check the supply voltage and make sure that
there is no over-or under-voltage exceeding 10% of the nominal value.
11. Pipework Systems
a) Certain properties of thermal fluid, including low surface tension, make it necessary to
pay particular attention to containing the fluid. Good pipework system design, welded
