For instances where the float needs to be removed, turn off the water to the system.
Remove the (red) cap on top of the stillwell. Unscrew the 3/8” PVC coupler that mates to
the feed water line and the black threaded flange connection protruding through the tank
wall. Unscrew the coupler that mates to the plastic spray ring. The float valve can now be
pulled out the stillwell. The float itself, can be unscrewed at the clevis hinge that mates with
the open/close poppet valve. To re-install the valve assembly, repeat steps in reverse order,
making sure to use Teflon tape for replacing all NPT connections. Replace red cap and
return water supply. Verify float does close once high level is reached and system is not
flowing water.
Quartz Rock
In order to accommodate various salt types, MIOX provides a cross-shaped, slotted pipe
manifold. Thread the manifold into the bottom tank adapter. Place 7 inches of ½” x ¼” NSF
quartz rock in the bottom of the tank. Rake it flat and cover the slotted pipe manifold. Place
5 inches of ¼” x
⅛
” NSF quartz rock on top of the first layer of quartz rock. Rake flat. Be
certain to rinse quartz rock for several minutes to remove dirt and debris prior to filling with
salt.
Brine Silos
Brine silos have their own specific installation instructions. Follow the manufacturer’s
recommendations for handling and installation.
Note: On initial start-up, cell replacement or when brine plumbing connections are
modified, air is introduced to the brine line. This air must be removed for proper
operation of the brine pump. Air locks in the brine line will prohibit consistent
brine flow to the cell.
Brine Boost System Installation (Optional)
The brine boost system ensures that sufficient brine pressure is supplied to the OSG to
maintain optimal cell amperage and is required on all RIO-S OSG installations. A brine
pressure boost system includes a centrifugal booster pump and pressure relief valve/back
pressure valve (Figure 19). A separate electrical circuit is required for the brine boost
system. The brine boost pump should be mounted as low as possible in relation to the brine
generator to ensure a flooded suction.
