TACTICAL WATER PURIFICATION SYSTEM (TWPS)
OPERATOR MAINTENANCE PROCEDURES
MICRO-FILTRATION SYSTEM
g. Roll two O-rings onto the upper end of the submodule, past the O-ring grooves, and up to
the exposed screen of the submodule. The O-rings will be rolled down into their grooves
at a later step.
h. Place the second filtrate cup fully over this end of the submodule. The filtrate cup will
loosely slide onto the submodule, allowing for easier manipulation.
i. Install the two O-rings on the bottom head, two on the top head, and two at each end of
the center tube. Make sure that the O-rings are not twisted. Lubricate these eight O-rings.
WARNING
Two-person lift. Two people are required to safely move the MF module. Lift with
your legs, not your back. Failure to observe this warning can result in back injury.
5. Install the submodule into the MF assembly as follows:
a. Install the center tube/submodule assembly into the unit, pushing the lower filtrate cup
into the lower head.
b. Push the top filtrate cup up into the upper head.
c. Roll the two O-rings on the upper end of the submodule up into their grooves. Make sure
that the O-rings are not twisted. Lubricate the O-rings.
d. Install a pair of clips on the upper end of the submodule, and use them to lift the
submodule into the upper filtrate cup until the clips contact the filtrate cup.
WARNING
Clearance between the outer sleeves of the MF modules is tight. Each filter
module contains gear-like ribs around the sleeves. Care must be taken not to get
fingers caught between filter module outer sleeves. Failure to observe this
warning can result in injury to fingers and hands.
e. Lift the top outer sleeve and push it firmly into the upper head until the O-rings engage.
Screw the outer sleeve all the way onto the upper head.
f. Lift and support the lower outer sleeve to gain access to the lower filtrate cup and
submodule.
g. Slide the lower filtrate cup downward.
NOTE
The filtrate cup must be low enough and the submodule must be high enough to
allow correct fitting of both clips. If the submodule stretches slightly while sliding
the filtrate cup, it must be lifted in order to fit the clips in place. Avoid squeezing
the exposed screen against the fibers.
h. Install the clips on the lower end of the submodule.
