I. DESCRIPTION
A. PURPOSE AND BASIC SPECIFICATIONS
The system is intended to receive, store and feed the distillate tc, the
battery wells for battery make-up. As distilled water is consumed, I- e
ing the stowage tanks is accomplished by the use of the electric distilling
plant.
The distilled water stowage tanks are of the following stowage capa-
cities:
tank No.1 - 2730 lit;
tank No.2 - 2060 lit.
The total distilled water stowage capacity of the submarine is
4790 lit.
The basic char-a.cteristics of the distilling system-pipe lines are
tabulated below.

Prior to feeding the distillate tor filling the tanks and for make-up of
the battery, the distillate shall be sampled and tested-in accordance with
the Submarine Storage Batteries 7,_7_,keep Instructions.
A sample of water is taken through sampling -.-alve 24.
If water does not correspond to the requirements specified in ti-.4.2

II. MAINTENANCE INSTRUCTIONS
A. GENERAL SUPERVISION AND UPKEEP
I. In the course of operation of the distilling system, keep the fitiings
and the pipe lines in good order, take care that they are properly secured
to the hull structural members.
2. When operating the distilling system:
(a) keep the pipe lines and the fittings in constant readiness for im-
mediate action;
(b) ensure that the pipe lines, joints and fittings are perfectly tight;
immediately eliminate leaks in union connections and in gland packings;
(c) see to it that all the valves and the hoses are always easy to get..at;
(d) smoothly open the valves on the pipe lines under pressure;
(e) tighten up and repack the glands if necessary.
3. Care should be exercised to see that the pressure gaug::- 3 and the
safety valves arc n good order and sealed; if the pressure gauges produce
wrong readings, thei.- sealing is disturbed or the term of their check is up,
they shall, be sent for checking or replaced. -- -
4. With the distilling plant in operation, pay attention to condition of the
fittings and the pressure gauges, See to it that the pipes are free from cracks
and their joints are perfectly tight.
5. In case of disassembly and reassembly of the pipes care should be
taken that no foreign matter is allowed to get into _them, for which purpose
blank off the ends of the disconnected pipes with wooden or metal plugs.
Never blank off the pipes with rags since they are likely to get into the
disassembly and reassembly of the pipes use the specified tools
