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.
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 each shower.
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 105F.
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 can.
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.
I. WATER PUMP HEATER-HOSE 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 water heater.
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 pump.
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.
Locate the bath unit so drainage from the shower area is carried downstream or downhill from the suction hose strainer to prevent wastewater from beingContinue Reading
