The use of two 45˚ in place of a 90˚ allows for the best debris removal
and minimizes large debris from getting caught in the line.
MDX-R3 SYSTEM DESIGN
These MDX-R3 instructions provide two methods to choose from, with additional methods for
specific jurisdictions, (California specifically but not limited to that state). Your local codes may
require additional safety measures. Paramount Pool & Spa Systems and its representatives cannot
recommend or endorse installation methods other than those provided in these MDX-R3 instructions.
Maximum Pump Size:
MDX-R3 is rated for a maximum of 132 GPM (500 LPM). 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 132 GPM (500 LPM).
NOTICE
In the event of one suction outlet being completely blocked, the remaining suction outlets serving that
system shall have a flow rating capable of the full flow of the pump(s) for the specific suction system.

NOTICE
Plumbing of the included enlarged suction element (13” of
4” pipe) to the 4" port of the MDX-R3 is required.
After the
enlarged suction element, the included reducer adapter may then
be used to reduce the pipe size to 2½”. A 3” coupler may be attached to the outside diameter of
the reducer or a 4” coupler directly to the enlarged suction element for systems where the flow
through the MDX-R3 is intended to exceed 90 GPM.
Use of 2½” pipe minimum throughout
the suction side of the system is strongly encouraged for optimum performance.
For
your convenience, Paramount Pool & Spa Systems includes the enlarged suction element, and the
reducer adapter with the MDX-R3. To order separately, please see page 12 for the part number.
