OPERATING INSTRUCTIONS

2-1. GENERAL.

The instructions in this chapter are published for the informa-

tion and guidance of personnel responsible for operation of the

aviation fuel laboratory. The operator must know how to perform

every operation of which the aviation fuel laboratory is capable.

This chapter provides instructions on starting and stopping various

items in the laboratory. Since nearly every job presents a different

problem, the operator may have to vary given procedures to fit the

individual job. Power to the laboratory is provided by a 15 kw, 60

Hz, 120-208 vac generator or equivalent electrical power from

commercial source.

Grounding for the laboratory is provided through

the 4-wire cable from the power generator to the

laboratory junction box (2, fig. l-l). Be sure

generator and laboratory are properly grounded.

Failure to observe this warning may result in

serious injury or death.

Main power circuit breaker CB-1, (4, fig. 1-4)

must be in the ON position prior to starting

generator. CB-1 shall NOT be manually shut off

except in an emergency. Turning CB-1 ON with

power applied could result in spark ignition of

any combustible vapors that may be present in the

laboratory.

Ensure that the power cable is properly connected

to the generator set. Color coding is as follows:

Black wire - Phase A (Ll), White wire - Phase B

(L2), Red wire - Phase C (L3), Green wire - Ground

(G).

The ice maker and analytical balance may be

adversely affected so that they are either inoper-

able or give incorrect readings if the laboratory

is not properly leveled.
