CONCRETE FOOTING
MDX² Plumbing (Fig. 1)
1.
Position the MDX² Sump even with the finished
depth of the pool, spa or basin
(Fig. 1)
.
Whichever pool base is used, the drain sump must
be encased in concrete as shown to anchor it in
place
2.
Position the REQUIRED SDX High Flow Safety
Drain on a sidewall of the pool below water level (if
pool will be winterized, place it high enough to
reach from the deck). Option: The SDX High Flow
Safety Drain may be positioned on the floor a
MINIMUM of three (3) feet away from any other

Liner Install
1.
Make sure bottom gasket is in place before
installing liner.
2.
Set liner in pool and draw tight with vacuum.
3.
Install top gasket, seal ring and 12 screws.
4.
Cut out liner inside of sump. Be sure to trim liner
right up to the inside diameter of seal ring.
Hydrostatic Fitting
The hydrostatic port inside the MDX² Sump is
equivalent to a 2" Threaded Female Adapter and a 2"
Slip Fitting Outside the MDX² Sump. Paramount
recommends the use of the 2” thread plug provided. Do
not use check valves here that are prone to sticking
open causing the need to open the drain cover
exposing a suction risk. This port is for the purpose of a
hydrostat only. If a hydrostat is not used, plug this port
from bottom with pipe and cap. Do not install any
suction equipment (pump) to this port
