CONTAINERIZED SHOWER & SHOWER, ENCLOSED UNIT, SYSTEM
THEORY OF OPERATION
Each model of shower is a self-contained, portable facility accommodating twelve individually controlled,
modular shower units (1), internal fluorescent lighting (2), an exhaust fan (3), and a sump pump (4). Cold
water inlet (5), hot water inlet (6), and graywater discharge (7) connections are fitted to the container (8).
An internal water distribution system (9) uses -inch copper piping or flexible hose to distribute freshwater
to the showers.
On the Containerized Shower (stand alone configuration), a power service panel (10) contains a 60A input
connector (11), two 20A connectors (12), and a double 110V AC GFCI convenience outlet (13). A circuit
breaker panel (14) and internal power lines distribute power to the interior lights (2), the space heater (15),
and the sump pump (4). Power for the M-80 water heater (16), 30 gpm water pump (17), and shave stand
lighting (18) is supplied through external connectors on the power service panel (10).
The Shower, Enclosed Unit, System (Force Provider configuration) receives power, freshwater, and
graywater service as a component of Force Provider. Hot water for the Shower, Enclosed Unit, System is
provided by an M-80 water heater (16). The M-80 water heater and additional components for the
Shower, Enclosed Unit, System are packed in TRICON containers 4A and 4E in the Force Provider
packing plan (refer to TM 10-5419-206-13).
Modified General Cargo Container
The container (8) is a modified 20-foot x 8-foot x 8-foot ISO shipping container. Its external dimensions
and transportation characteristics are not affected by the shower modifications. User access to the
container is gained through a personnel door (19) at one end. Operator access for the Containerized
Shower is gained through double service doors (20) at the other end of the container. The Shower,
Enclosed Unit, System is not fitted with service doors. Both models are electrically grounded through the
power source. The Containerized Shower may also be grounded using a grounding rod (21) connected to
a grounding terminal (22) located on the power service panel (10).
A space heater (15) located above the mixer valve (23) provides heat for the Containerized Shower. A
roof-mounted exhaust fan (3) provides ventilation for both models. The exhaust fan is operated by a
switch accessible by the personnel entry door.
TEMPER Tent Section With Bootwall
A TEMPER tent (24) section with modified endwall (bootwall) is connected to the personnel door (19) end
of the container. For the Containerized Shower, two shave stands (18) accommodating three persons
each are located in the 16-foot TEMPER. For the Shower, Enclosed Unit, System (Force Provider)
configuration, four shave stands are available to accommodate twelve persons in a 32-foot TEMPER.
Freshwater supply and graywater outflow for the shave stands are conducted through flexible hoses
connected to the container. Power for the TEMPER interior and shave stand lights is provided through the
convenience outlets on the container power service panel (10) on the Containerized Shower, and through
Force Provider power supply on the Shower, Enclosed Unit, System.
