Plumbing Design:
NOTICE:
The MDX Debris Removal System
TM
requires the proper
installation of all anti-entrapment features including the
SDX High Flow Safety Drain
TM
and vent line or approved
Safety Vacuum Relief System (SVRS).*
Install 2½” pipe between MDX and the Debris Collection
Point which may be the optional Paramount Debris
Canister, or a self-priming pump basket.
NOTICE:
Extensive testing has proven that pipe smaller than 2½"
creates a significant hair entrapment hazard anytime it is
used with a large opening drain. Even 2" pipe poses an
excessive hair entrapment hazard; therefore 18" of 2½"
pipe is required as illustrated.
NOTICE — Maximum Pump Size:
MDX is rated for a maximum of 90 GPM. While system
flow rate will vary with pump size and the Total Head
Loss for a given system, virtually any modern pump is
capable of exceeding this limit, therefore it is the
responsibility of the system designer to make sure it is
not possible to exceed 90 GPM.
Plumbing:
• Position the MDX Sump 1" below the finished
depth of the pool, spa or basin. (Fig. 1)
• Position the REQUIRED 2nd Suction Outlet on a
sidewall of the pool, spa or basin. Option: the 2nd
Suction Outlet may be positioned on the floor a
MINIMUM of three (3) feet away from any other
Suction Outlet.
HYDROSTATIC FITTING:
The hydrostatic port inside the MDX Sump is equivalent
to a 2" Threaded Female Adapter and a 2" Slip Fitting
Outside the MDX Sump. For non-hydrostatic
installations, install the 2" plug provided.
