5. Check radiator coil and generator air intake screen for cleanliness. If required, clean using compressed air,
reversing the normal air flow.
6. Check air cleaner for cleanliness and clean if necessary. (Refer to Section 5.4.12 .)
7. Check in-line fuel strainer and clean if necessary. (Refer to Section 5.4.4 .)
8. Drain water from fuel tank sump and filter bowl.
9. Fill fuel tank with diesel fuel. (Refer to Section 2.10 , table entry g.)
10. Check air intake heater amperage. (Refer to Section 2.10 , table entry h.)
11. Check battery terminals for cleanliness and secureness. If required, clean, then coat with a battery terminal
sealant.
12. Check, and if required, tighten all electrical connections.
13. Check, and if required, tighten all hardware (brackets, etc.).
14. Ensure the main generator set circuit breaker (CB1) is in the OFF position. Connect power cable to refriger-
ation unit and proceed to Section 3.3.2 .
3.3.2 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 con-
junction with the air intake heater.
NOTICE
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, operate 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 engine workshop manual listed in
Section 2.2 ).
1. Standard Units
a. Make sure that CB-1 is in the OFF position.
b. Hook up the 460 volt cable from the refrigerated unit to the Genset receptacle.
c. Hold intake heater switch (see Figure 2.10 ) in the PREHEAT position. Suggested hold times for a cold
engine are as follows:
COLD ENGINE PREHEAT TIMES
Ambient Temperature Time
78°F/26°C 5 seconds
32°F to 78°F (0° to 26°C) 10 seconds
18°F to 32°F (-8° to 26°C) 20 seconds
Below 18°F/-8°C 30 seconds
