The first procedure is to check all parts against the
bills of material. This action helps to ensure that all the
parts have been included in the assemblies. Visually
inspect all the components for damage. Check for
dents, cracks, broken parts, and loose or kinked
connections. If an item is missing or damaged, you
should report the discrepancy to your supervisor, so
steps can be taken to remedy the situation.
PORTABLE BATH UNIT
The nine-shower head Portable bath unit is a liquid
fuel-fired water-heating device that supplies warm
water to each of the shower nozzles. The bath unit is
equipped with the necessary water heater, water pump
assembly, mixing unit, hoses, and shower stands to
supply all of the warm water needed for operation. The
water pump draws water through the suction strainer
and the hose from the water source and forces it through
the discharge hose to the water heater. The water heater
raises the temperature of the incoming water and
maintains it at the desired temperature. The heated
water is then forced through one discharge hose to the
mixing unit where it is mixed with cold water to provide
water at the desired temperature to the shower heads.
The electrical power required to operate the bath
unit should be supplied by a self-contained portable 3
kW, 60 Hz, 208 V, three-phase power generator source.
All of the components of the bath unit that are operated
electrically should be grounded through a fifth wire
incorporated in the power cables.
A description of major components to the portable
bath unit is listed below. The location of each
component is shown in figure 2-1
A. A SHOWER STAND ASSEMBLY. Eachofthe
three shower-stand assemblies come equipped with
three shower heads. Each shower head has a valve to
control the water flow. A curtain is supplied to enclose
B. WATER HOSE ASSEMBLY. There are five 1-
inch inside diameter (ID) hoses, each measuring 7 1/2
feet in length. The hoses interconnect with the water
pump assembly, the water heater assembly, the mixing
valve assembly, and three shower-stand assemblies
C. MIXING VALVE ASSEMBLY. The mixing
valve assembly mixes hot water from the water heater
and cold water from the water pump and water source to
provide heated water to the shower stands at
temperatures of approximately 105°F.
D. WATER HEATER. The water heater is a self-
contained, liquified fuel-fired boiler that heats water
supplied by the water pump. The major subassemblies
or components that make up the water heater are the
water vessel, the burner assembly, the blower assembly,
the control box assembly, the sight glass assembly, and
the transformer and ignition cables.
E. DRUM FILL ADAPTER ASSEMBLY. The
drum fill adapter assembly can be used with either a 55
gallon fuel drum or a 5-gallon gasoline can. The fuel
level can be checked visually and refueled without
disconnecting the fuel lines.
F. FUEL CONTAINER. The fuel container may
be either a 55-gallon fuel drum or a 5-gallon gasoline
G. FUEL FEED AND RETURN HOSE
ASSEMBLIES. Flexible hoses provide supply and
return fuel between the fuel storage container and the
fuel pump assembly on the water heater.
H. POWER CABLE ASSEMBLY. The power
cable assembly consists of two cables that extend from
the Power source to the bath unit. The short cable
connects to a 208 V, three-phase Power source. The
long cable connects to the short cable, the water heater,
and the water pump.
ASSEMBLY. The assembly consists of one 1 1/24nch
ID hose, measuring 6 feet in length that connects the
water pump to the water heater.
J. WATER PUMP. The water pump draws water
from the source through the intake hose and the in-line
strainer then supplies it through a discharge line to the
K. SUCTION HOSE ASSEMBLY. The suction
hose assembly has one l-inch ID hose, measuring 25
feet in length that connects the water supply to the water
L. SUCTION STRAINER ASSEMBLY. The
suction strainer assembly is connected to the suction
hose assembly. It prevents leaves and debris from
entering the water system.
Setting Up the Bath Unit
Locate the bath unit so drainage from the shower
area is carried downstream or downhill from the
suction hose strainer to prevent wastewater from being
