4-13. FLEXIBLE DUCTS. Two flexible ducts (storage and supply) are contained in the accessories storage box located
on the trailer. To attach the ducts to the air conditioner duct adapters, proceed as follows:
NOTE
Two people are required for installation.
a.
Remove flexible ducts from accessory box.
b.
Remove adapter end cover from the supply and return duct adapters. Store covers inside accessory box.
WARNING
Generator-set engine exhaust is located near the air conditioner and may enter the
air conditioner air inlets if they are not properly sealed. Exhaust gases can cause
eye and respiratory irritation, and may lead to carbon monoxide asphyxiation if air
conditioner air inlets are not properly sealed.
NOTE
Observe air flow directional arrow on flexible ducts. Refer to figure 4-7.
c. Slide the end of the flexible duct onto the return duct adapter, making sure the directional arrow is pointing in the
correct direction (refer to figure 4-7). When properly in place, the hem containing the strap is passed over the raised rim
of the duct adapter. Make sure the strap ends are positioned to allow tightening of retaining clamps.
d. Tighten the screw sufficiently to clamp the flexible duct securely onto the return duct adapter. Do not over tighten;
the duct will carry airflow at a relatively low pressure.
e. Repeat steps c and d as necessary to attach the supply flexible duct to the supply duct adapter, making sure the
directional arrow is pointing in the correct direction (refer to figure 4-7).
4-14. FIRE EXTINGUISHER. Remove fire extinguisher from accessory box and place securely in
holder. Refer to
figure
4-15. AUXILIARY FUEL LINE CONNECTION.
The generator-set has provisions for obtaining fuel from an external source, such as a 55-gallon diesel fuel drum. This
enables operation for extended periods, without manually refilling the fuel tank. The external fuel source can be
connected as follows.
a.
To connect auxiliary fuel source, perform the following steps.
(1)
Place the external fuel source several feet, but not more than 25 feet, away from the generator-set.
(2)
(3)
Make sure the fuel drum adapter components are clean.
(4)
Thread the fuel pickup tube (1) into the adapter (2).
