MDX-R3 Plumbing (Fig. 1)
1. Position the MDX-R3 Sump even with the
finished depth of the pool, spa or basin
(Fig. 1). Orientate the sump so the elbow is
perpendicular to inside wall or end wall of pool.
Whichever pool base is used, the drain sump
must be encased in concrete as shown to
anchor it in place.
2. Position the REQUIRED SDX2 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 SDX2 High Flow Safety Drain may be
positioned on the floor a
MINIMUM of one (1) meter away from any other
Suction Outlet.
HYDROSTATIC FITTING: The hydrostatic port inside the MDX-R3 Sump is equivalent to a 2" Threaded
Female Adapter and a 50mm Slip Fitting Outside the MDX-R3 Sump. This port is for the purpose of a
hydrostat only. 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. 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!
Pressure Test-READ BEFORE INSTALLATION:
New Style Test Plug
The 4" pressure test plugs (005-252-1610-00) use
an o-ring to make the seal.
Wrap once with Teflon tape to prevent plastic
threads from binding. Insert plug into threaded
socket. Use an adjustable wrench, a 1½" 12 pt
socket or pliers on lug and tighten by hand until
snug. Over tightening may cause parts to break.
Pressure should remain on the system through
construction until interior cleanup.
