6.10 COLD WEATHER
OPERATION
The DE-18 was designed for operation in severe cold
environments. There are three sub-systems of the
cold weather equipment. They are:
• Adjustable Louvers (on the end of the
machine)
• AC Heaters
• Ether Starting Aid
In cold weather it is important to keep an eye on the
compressor discharge temperature, T5. This
temperature should not be lower than 40°F (5°C). If
T5 dips below this temperature, the condensate will
be at risk of freezing and could cause extensive
damage to the discharge system, especially the
aftercooler. The machine is fitted with adjustable
louvers at the cooling air intake. These louvers
should be adjusted so that the discharge
temperature, T5 does not dip below 40°F (5°C). This
means that the louvers will be adjusted to close off
some of the cooling air through the intake. In some
extremely cold areas, the louvers may be adjusted so
that the cooling air flow is completely closed off.
In addition to the adjustable louvers, are the AC
heaters. The heaters are recommended to be
plugged-in at temperatures below 55°F (13°C). The
heaters will keep the engine block, compressor oil
(T6), and batteries warm, and will also keep the
condensate from freezing in the water trap and
drains.
An ether starting aid system is also installed on the
DE-18. The engine will decide for itself when this
system is needed and is only used at colder
temperatures. The ether bottle should be checked
periodically for fill level. Ether should not be sprayed
into the engine/compressor intake under any
circumstances. Doing so could cause extensive
damage to both the engine and compressor as well
as causing an explosion within the machine.
NOTE
Compressor must be rotated within 24
hours of machine shutdown. Not doing so
may allow rust to form inside the com-
pressor.
