MIRCS
± The±MIRCS±has±three±key±components±that±need±exercise:±the±generator±(15-kW±tactical±
quiet±generator),±environmental±control±unit±(ECU)±and±refrigeration±unit±(RU).±The±RU±and±
generator±need±to±run±at±least±once±a±month±for±a±minimum±of±two±hours.±The±ECU±should±
be±run±quarterly.
± The±generator±and±RU±benefit±from±exercise±by±keeping±their±batteries±charged.±Exercise±
lubricates±the±moving±parts±of±the±engine±and±fuel±injectors,±and±prevents±engine±seals±
from±drying±out.±Additionally,±exercise±prevents±the±RU±compressor±shaft±seal±from±drying±
out±and±leaking±refrigerant.
± Before±starting±the±generator,±deploy±the±generator±supports±in±accordance±with±WP±
0008-7±through±0008-11±in±TM±10-4110-263-10±(Jun±10).
± Follow±procedures±in±WP±0009-1±for±operating±the±RU.±Before±operation,±remove±the±RU±
cover±and±install±the±exhaust±extension.±
± After±operation,±allow±the±exhaust±extension±to±cool,±remove±it,±stow±it±and±replace±
the±cover.±Failure±to±replace±the±cover±will±allow±water±to±get±into±the±system,±causing±
severe±damage.
± The±ECU±is±helped±when±moving±parts±such±as±the±compressor±and±fans±are±exercised.±
To±properly±start±the±ECU,±the±MIRCS±must±be±set±up±IAW±WP±0008±in±TM±10-4110-263-10±
(Jun±10),±which±means±the±platforms±must±be±lowered±and±the±softwalls±deployed±with±
support±rods.±
± Follow±the±PMCS±guidelines±in±WP±0023±of±TM±10-4110-263-10±(Jun±10).
MTRCS
± Units± should± exercise± the± MTRCS± monthly.± Otherwise±
the± seals± within± the± refrigeration± unit± can± dry± out± and±
refrigerant±can±escape.±Refrigerant±loss±means±an±MTRCS±
that± will± not± cool± properly.± Units± have± reported± low±
refrigerant±levels±in±MTRCS±after±fully-charged±systems±sat±
idle±for±an±extended±time.
± To±help±prevent±refrigerant±from±escaping,±operate±the±
MTRCS±monthly±for±at±least±two±hours.±When±the±system±is±
not±going±to±be±used±for±90±days±or±longer,±the±refrigerant±
should±be±pumped±down±into±the±receiving±tank.±Follow±
the±pump-down±procedures±in±WP±0032±of±TM±10-8145-
222-13±(Sep±10).
LADS
± Proper± shutdown± of± systems± is± just± as± important± as±
regular±workouts.±With±LADS,±this±includes±draining±all±the±
water±from±the±system±to±prevent±damage±from±freezing.±
Follow± the± shutdown/cool± down± and± draining/storage±
procedures±in±WP±0016±of±TM±10-3510-221-10±(Jul±08).±
LADS,±MTRCS,
MIRCS……
just like
human bodies,
equipment
starts to
suffer when it’s
not regularly
exercised.
three systems
that need regular
workouts are the
multi-temperature
refrigerated
container system
(mtrcs), mobile
integrated remains
collection system
(mIrcs), and the
laundry advanced
system (lads).
even new
systems
can turn
nmc if they
sit idle
too long.
MTRCS

LADS
yo, buddy!
check it
out!
with my regular
workouts, I’m all
charged up and
ready to run!
boy, sure
wish I had
your get-up-
and-go.
I could
really
use some
exercising!
