Dear Editor,
If you operate Avengers in cold weather, it can be difficult to fire up the
primary power unit (PPU).
Some Soldiers may not
be aware that you can prime
the PPU to make it easier
to start. Just keep pushing
‘down on the primer, which
is inside the PPU, until it’s
hard to move. Then start
the PPU. It should fire up
right away.
But before you turn on
the
environmental
control
unit (ECU)/PPU, make sure
the blower is off and the
temperature
selector
is
centered between HEAT and
COOL. Otherwise, the ECU/
PPU won’t start and you can
mistakenly think you’ve got
major problems.
One other ECU/PPU tip:
Measure as you fill it with oil.
It holds only 3
1
/
2 quarts and
it’s easy to overfill. And that
can lead to leaks. Pour in
1
/
2 quart and then measure.
Keep doing that until oil
reaches the FULL line.
