2.3 STARTING AND STOPPING INSTRUCTIONS
2.3.1 Pre-Start Inspection
a. Check engine lubrication and fuel filters, oil lines, and
connections for leaks. If required, tighten connec-
tions and/or replace gaskets.
b. Check engine lubricating oil level. (Refer to para-
graph 1.10, table entry f.)
c. Check poly V-belt for fraying or cracks and proper ten-
sion. (Refer to paragraph 4.4.11).
d. Check radiator hoses for leaks and check radiator
coolant level. (Refer to paragraph 1.10, table entry k.)
e. Check radiator coil and generator air intake screen for
cleanliness. If required, clean using compressed air,
reversing the normal air flow.
f. Check air cleaner for cleanliness and clean if neces-
sary. (Refer to paragraph 4.4.12.)
g. Check in
−
line fuel strainer and clean if necessary.
(Refer to paragraph 4.4.4.)
h. Drain water from fuel tank sump and filter bowl.
i. Fill fuel tank with diesel fuel. (Refer to paragraph 1.10,
table entry g.)
j. Check air intake heater amperage. (Refer to para-
graph 1.10, table entry i.)
k. Check battery terminals for cleanliness and secure-
ness. If required, clean, then coat with a battery termi-
nal sealant.
l. Check, and if required, tighten all electrical connec-
tions.
m.Check, and if required, tighten all hardware (brack-
ets, etc.).
n. Ensure the main generator set circuit breaker (CB1)
is in the OFF position. Connect power cable to refrig-
eration unit and proceed to paragraph 2.3.2.
2.3.2 Starting Instructions
Before start up, both the Genset circuit breaker (CB1)
and the refrigerated unit should be OFF. After start up,
the Genset unit should be run for at least two minutes to
allow the power source to stabilize before supplying
power to the refrigerated unit. This will eliminate the
potential of any cold start transient spikes from reaching
the refrigerated unit. Cold start transient spikes can
potentially cause nuisance over voltage alarms on
refrigerated units that are sensitive to electrical spikes
or transients.
WARNING
Beware of moving poly V-belt, belt driven
components and hot exhaust components.
WARNING
Under no circumstances should ether or
any other unauthorized starting aids be
used in conjunction with the air intake
heater.
NOTE
Piston rings in engines that have operated less
than 100 hours may not be fully seated. This
may lead to the possibility of oil seepage from
the exhaust pipe. To properly seat the rings, op-
erate the engine under full load for a period of 24
hours. If the condition persists, check valve
clearance when the engine is cold. (Refer to en-
gine workshop manual listed in paragraph 1.2).
a. Standard Units
1 Make sure that CB-1 is in the OFF position.
2. Hook up the 460 volt cable from the refrigerated unit
to the Genset receptacle.
3. Hold intake heater switch (see Figure 1-7) in the
PREHEAT position. Suggested hold times for a cold
engine are as follows:

4. With the intake heater switch held in the PREHEAT
position, place the ignition switch in the
START posi-
tion.
5. After the engine has started, continue to hold the in-
take heater switch in the PREHEAT position until the
engine develops sufficient oil pressure to close the
oil pressure safety switch (approximately 5
seconds). When released, the intake heater switch
will automatically return to the OFF position and the
heater will remain energized for 3 minutes.
b. Units with Auto Start
1 Make sure that CB-1 is in the OFF position.
2. Hook up the 460 volt cable from the refrigerated unit
to the Genset receptacle.
3. Place the Ignition switch (IGN) in the RUN position.
4. If the low coolant sensor (LCS) is immersed in cool-
ant, the auto restart module will energize the heater
for 30 seconds and the safety buzzer will sound. Af-
ter the 30 second delay, the unit will attempt to start.
