MDX DEBRIS REMOVAL SYSTEM DESIGN
NOTICE:
The M M D D X X D D e e b b r r i i s s R R e e m m o o v v a a l l S S y y s s t t e e m m requires the proper installation of all anti-entrapment features including the 2nd
Suction Outlet and at least one of the Vacuum Breaker installations illustrated in the two options. *
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:
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.
*The MDX instructions provide two design options to choose from: other methods may be available depending on your local codes. Follow all
regulations requiring specific plumbing solutions and you may use officially approved vacuum-breaker products and vacuum breaker methods.
Additional ways to prevent a single-point-suction hazard are available through NSPI's Standard for Residential Swimming Pools. Any of these
options may be used as long as it is NOT possible for a swimmer to be exposed to single-point-suction when drains are fully disassembled.
NOTE: Paramount Pool & Spa Systems and its representatives can not recommend nor endorse installation methods beyond those provided in
the MDX Debris Removal System instructions.
MDX DEBRIS REMOVAL SYSTEM INSTALLATION
NOTICE:
18 inches of 2½" pipe is required to be connected to the center outlet of the MDX Debris Removal System. After the
18 inches of 2½" pipe you may reduce to a smaller pipe size, although it is not recommended. Use of 2½" pipe
throughout the suction side of the system is strongly encouraged for optimum performance. For your convenience,
Paramount Pool & Spa Systems includes the 18 inches of 2½" pipe plus coupler with the MDX Debris Removal
System. To order separately, please see page 6 for the part number.
