NOTE
There are two compartments within the MTRCS accommodate cooling and freezing
of perishable items. Each compartment is operated independently of the other and
has a separate evaporator unit.
Each evaporator contains two evaporator blower motors. Removal and reinstallation
of the blower motors is the same for each evaporator. The replacement procedure for
each evaporator addresses removal of one blower motor only.

container frame when in the open position. A gust of wind can cause unsecured
doors to slam shut with great force possibly causing severe injury or death to
personnel.
