A 25-foot rubber suction hose assembly (fig. 3-2) is furnished with the bath unit to convey water from the water source to
the water pump. Three 25-foot canvas hose assemblies (fig. 3-3) are furnished-one hose carries water from the water
pump to the water heater and the other two hoses carry the warm water from the water heater to the two shower stands.
The hoses are equipped with quick coupling connections. On one end of each canvas hose, the connection consists of a
coupler fitted with a gasket and two locking levers. The other end consists of an adapter with a shank. Each end of the
rubber suction hose consists of a coupler with a gasket and two locking levers. The following instructions apply to the
rubber and to the canvas hose assemblies.
a. Inspection. Inspect the assembly for dirty, cracked, broken, collapsed, and deteriorated hose; for broken or
missing clamps; and for broken locking levers, couplers, adapters, and gaskets.
b. Removal. Disconnect the canvas hose assembly from the water heater and the water pump or from the water
heater and the shower stand (as applicable). Disconnect the rubber hose assembly from the suction hose strainer and
the water pump.
c. Cleaning. Scrub the hose assembly with a brush, using a mild, soapy-water solution.
d. Installation. Replace defective hose assembly with a serviceable one as authorized. Reverse the procedure in b
above, being sure to insert a new gasket in the coupler. Insert the adapter into the coupler and pull the two locking levers
of the coupler downward. This action locks and seals the coupler and the adapter, thus preventing leaks.
