Warning
In case of accident from electric shock, shut down power unit at once. If power unit cannot
be shut down, free victim from live conductor with a board or any non-conductor. If victim is
unconscious, apply artificial respiration and obtain medical help.
c.
Operation to Deliver Cooled Air. Refer to figure 2-26 for operation of cooled air system.
Note
Vent air doors (fig. 2-21) should be opened as required during operation of the cooled air
system to permit intake of makeup air to the system.
Caution
Condenser air inlet panels (fig. 2-21) and condenser air outlet doors (fig. 2-21) must be open
before operating the cooled air system.
d.
Operation to Deliver Heated Air. Refer to figure 227 for operation of heated air system.
Note
Vent air doors (fig. 2-21) should be opened as required during operation of the heated air
system to permit intake of makeup air to the system.
e.
Operation to Deliver Ventilating Air. Refer to figure 2-28 for operation of ventilating air system.
Note
Vent air doors (fig. 2-21) should be opened as required during operation of the ventilating air
system to permit intake of makeup air to the system.
f.
Operation to Deliver Compressed Air. Refer to figure 2-29 for operation of compressed air system.
g.
Operation to Deliver Hot and Cold Water. Refer to figure 2-30 for operation to deliver hot and cold water.
Note
Water system shall have been primed and connected as described in paragraph 2-3, b, (5)
prior to attempting water delivery.
h.
Operation to Provide Vacuum Suction. Refer to figure 2-31 for operation of the vacuum system,
i.
Emergency Operation. If the protective devices in the power unit shut down engine or generator operation for
any reason other than engine overspeeding, the protective devices can be bypassed and operation of the power unit
continued on an emergency basis. When such operation is imperative, open the lockout cover over the emergency
operation switch (fig. 2-22) and place switch in ON position. When emergency operation is no longer required, place the
switch in the OFF position and correct condition that caused actuation of the protective devices before continuing
operation.
Warning
The emergency operation switch should be used only in extreme emergencies when need for
continued operation justifies risks incurred in loss of equipment and possible injury to
personnel.
j.
Standby Operation. When it is desirable, or necessary, to have a standby power unit available for immediate
takeover of 60 Hz and 400 Hz electrical power delivery in event of malfunction of an operating power unit, the standby
power unit should be connected as follows.
Note
Emergency power transfer electrical kit assembly is required for interconnecting the electrical
outputs of the standby power unit and the operating power unit.
(1)
Place standby power unit as close as practical to the operating power unit. If power units cannot be
positioned within 50 feet, additional cable assemblies will be required to interconnect the power units and the emergency
power transfer electrical kit assembly.
Note
If greater separation of power units is required, connect additional power cable assemblies
together and use adapter cable assemblies provided with electrical kit assembly to connect
additional standby operation cable assemblies together.
(2)
Check that standby power unit is in fully operable condition and that batteries are fully charged. Check that
standby unit is adequately supplied with fuel.
(3)
Check that all controls on standby unit are in OFF, OPEN, or prestart position. Refer to paragraph 2-14.
Check that engine air inlet door is secured in open position.
(4)
Connect 60 Hz and 400 Hz power cable assemblies to output receptacles on electrical output connection
panel (fig. 2-3) on both power units and connect other end of cable assemblies to appropriate receptacles on emergency
power transfer electrical kit assembly.
