ASSEMBLY
1. CLOSE RO-V-11, media filter drain valve (figure 1, item 1).
! CAUTION
The media filter should be filled 2/3 full with substrate, at a ratio of two parts sand to one
part gravel. Overfilling the media filter with too much substrate can cause damage to
other systems cooled by the general service system, due to evacuation of the substrate
during backflush and rinse cycles.
2. Place 200 lbs (90.7 kg) of media sand in the media filter.
3. Place 100 lbs (45.4 kg) of size 8-12 media garnet in the media filter.
4. Lubricate a new O-ring (figure 2, item 3) with silicone lubricant and install the O-ring on the inlet elbow
(figure 2, item 2).
5. Install the inlet elbow (figure 2, item 2) in the media filter.
6. Install the inlet piping union (figure 2, item 1) to the inlet elbow (figure 2, item 2).
7. Remove the lockouts and tagouts (FM 55-502).
