INSULATED CONTAINER CONTINUED
Emergency Escape Hatches
There are two emergency escape hatches in the container in the form of two small doors that are hinged on their side.
One is located in the side door and the other is located in one of the rear doors. The emergency escape hatches can
be opened from inside the container only when the doors are closed. They are also used as blowout panels during air
transportation, when the handles are placed in the open position. There are three quarter-turn handles on the escape
hatches that when rotated clockwise will allow the emergency escape hatch to be pushed open.
Pressure Equalization Vent
Pressure equalization vents allow pressure equalization between the container interior and ambient air pressure.
These vents have been sized to prevent structural damage to the container.
Drains
The drains consist of a hole in the floor of the container that has a protective screen over it to prevent insects from
entering the container. Water condensate from the evaporators drains to the container exterior through drains within
the container wall.
Fuel Tank
CAUTION
The refrigeration unit diesel engine can operate using JP-8 or diesel fuel only. Do not
use any other fuel type. Do not use gasoline. Use of an unapproved fuel type will
result in damage to the refrigeration unit diesel engine.
A 75-gallon fuel tank is located at the lower front side of the MTRCS to provide either JP-8 or diesel fuel to power the
refrigeration unit. The tank is equipped with an external fuel pump to provide fuel to the diesel engine, a fuel liquid
level gauge, fuel level sending unit, filler cap, and two drain-cocks to allow fuel tank draining. The fuel tank is also
equipped with a fuel pump strainer located inside of the fuel tank that is used to trap sediment and other debris from
entering the fuel system.
Container Electrical
The container has electrical wiring that connects the various components throughout the MTRCS.
The container electrical consists of a power box, electrical cables, cam-action switches for power source selection and
internal lighting, fuel level indicators, visual and audible indicators, a microprocessor controller for the refrigeration
unit, and a temperature chart recorder.
Power Box Assembly
The Power Box Assembly (Figure 2) located on the front exterior under the refrigeration unit serves as a built-in power
supply circuit selector and protector while the MTRCS operates using external power sources. The power box has two
(2) fifty-foot attaching power supply cables and two six-foot pigtails with connectors that can be connected to four
different electrical input voltages as shown in Table 1. When using an external power source the rotary cam action
switches must be set to correspond to incoming electric voltage.
