TACTICAL WATER PURIFICATION SYSTEM (TWPS)
PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS
COLD WEATHER SET-UP OPERATION UNDER UNUSUAL CONDITIONS
RAW WATER INTAKE DEPLOYMENT
The OISS may be used for raw water intake whenever the beach conditions are suitable. The floating
inlet strainer should only be used when the raw water source is free of ice, or the ice is thin and the
strainer can be pulled below the water surface. The ice hole strainer should be used if the raw water
source is iced over and will safely support a person and the OISS is not used.
WARNING
Health hazard. Do not attempt to use product water hoses to handle raw water or
raw water hoses to handle product water. When installed with the proper adaptors
as directed, the hoses cannot be interchanged. Failure to observe this warning
and mixing hoses could cause contamination of water resulting in serious illness.
NOTE
If the OISS is to be used, refer to WP 0008, OISS Set-Up, for the procedures for
installing the OISS.
If the raw water source is not frozen and the floating inlet strainer is used, refer to
installing the floating inlet strainer and anchor. Use the anchor rope to pull the
strainer below the surface of the water.
If the ice hole strainer is to be used, deploy it as follows (see Figure 28):
WARNING
The blade of the ice auger is very sharp. Keep the blade cover on except when
using the auger. Avoid touching the blade. Failure to observe this warning may
result in severe injury.
NOTE
When selecting the location to open an ice hole, keep in mind that it is best to limit
the hose that will be exposed out of water to two 10 ft. lengths. Also, deeper water
will allow access to water that is above freezing.

preferred.
