Signal Words and Symbols Used In This Manual
This Owner’s Manual and Installation Guide contains specific precautions and symbols to identify safety-
related information. You will find DANGER, CAUTION, WARNING and NOTICE symbols which require
special attention. Please read them carefully and follow these precautions as indicated! They will explain how to
avoid hazards that may endanger you or persons using or maintaining your pool or spa.
SUCTION ENTRAPMENT HAZARD:
DEATH or SERIOUS INJURY will result from pool or spa drain covers or
grates that are improperly installed, missing, clogged, or broken.
• Inspect pool and spa before each use to ensure that drain covers and
grates are properly in place and secured.
• Ensure that drain covers are not damaged, cracked, broken, loose, clogged, not properly
secured, or missing because these conditions increase the chance of death or serious injury from
entrapment.
• If a drain cover is discovered damaged, cracked, broken, loose, clogged, not properly secured, or
missing, you shall:
• Close the pool or spa immediately; and,
• Post a closure notice and keep the pool or spa closed until an appropriate ANSI/APSP/ICC-16
2017 certified drain cover is properly installed.
• Missing, broken, or cracked SOFA component shall be replaced before bathers are allowed to use the pool.
• Loose cover/grates shall be reattached before bathers are allowed to use the pool.
DANGER
DANGER DEATH or SERIOUS INJURY will result from hair entanglement or
limb entrapment.
• Keep clear of pool and spa drains.
• Hair sucked into pool or spa drains will tangle and knot trapping the
swimmer underwater. Avoid placing your hair near a pool or spa drain.
• Avoid sitting on pool or spa drains because the suction can cause
severe intestinal damage, evisceration, and/or disembowelment.
WARNING indicates
a hazardous situation
which, if not avoided,
could result in death or serious injury.
WARNING
CAUTION indicates
a hazardous situation
which, if not avoided,
could result in minor or moderate injury.
CAUTION NOTICE is used to
address practices
not related to
physical injury.
NOTICE
• DEATH or SERIOUS INJURY will result if a drain cover or grate is
not installed and used correctly.
• Pool and spa pumps produce high levels of suction and move high volumes
of water, which can cause death or serious injury if a person comes in close proximity to pool or spa drains.
• SOFA shall not be located on seats or the back rests for seats
• Any modification that increases the flow rate of the circulation system shall require reevaluation of the cover/
grate and sump to ensure that the flow rating of the Suction Outlet Fitting Assembly (SOFA) is not exceeded.
• Keep clear of pool and spa drains to avoid death or serious injury from suction.
DANGER

DANGER DEATH or SERIOUS INJURY will result from contact with a
damaged, loose, or missing drain cover.
• Do not allow limbs to contact or be inserted into a drain pipe with a
damaged, loose, or missing drain cover. This could result in swelling of
the limb and/or trapping a swimmer underwater.
• Avoid mechanical entrapment of jewelry, swimsuit, hair decorations,
finger, toe, or knuckle in a drain pipe with damaged, loose, or missing
drain cover. This may result in trapping a swimmer underwater.
• Do not allow body to come into contact with a drain pipe that has a damaged, loose, or missing
drain cover. This may result in trapping a swimmer underwater.
MAINTENANCE INSTRUCTIONS & WARNINGS:
WARNING DEATH or SERIOUS INJURY can result from pool or spa drain covers
or grates that are clogged by debris.
• Any field modification made to a SOFA not authorized by the
manufacturer’s instructions shall void the SOFA certification.
• No modification shall be made to the SOFA structure or flow path unless the new configuration has
been certified as a new SOFA.
• All pool and spa drain covers may become obstructed by debris and should be cleaned periodically
due to clogging from debris, such as pieces of plastic, hair, fabric, twigs, leaves, seeds, etc.
• The frequency of periodic cleaning will vary depending on the amount and type of debris introduced
into the pool or spa
• Clogging of the drain cover will increase the suction effect and increase the likelihood of death or
serious injury from those hazards listed above.
• A clogged drain can negatively affect the safety of the drain.
• It is advisable to have a qualified pool or spa professional perform this inspection and debris removal
from the pool an spa drain covers.
• When servicing the drain cover, the pump connected to the suction must be turned off.
• Do not perform any service of the drain cover in water level above your waist.
• Use drain covers only with a pumping system rated for the corresponding flow or less. Failure to do
so can result in hair or body entrapment which can cause death or serious injury. If in doubt about
the rating of your system, consult a qualified pool or spa professional.
• Use only the supplied stainless-steel screws with the drain cover. Screws put into the frame
anywhere except in the original screw holes will not hold and will allow the drain cover to come off
the main drain, causing an entrapment hazard. If a screw hole(s) is stripped, inserts missing, loose,
or damaged, consult your owner’s manual and installation guide for proper steps to replace, correct,
or reattach the compromised drain or drain component.
• The use of adhesives or other attachment methods that prevent access to suction piping or SOFA
components requiring periodic service is prohibited.
WARNING Suction can pose a serious hazard to swimmers just as electricity can be a
hazard. Both are important for proper water filtration and both must be treated
with respect. Suction safety begins with a professional design that includes a
quality suction system installed by a certified contractor.
Certified builders will address the following issues when designing and installing a proper filtration system:
• Properly bond-grounded pumps, time clocks, switches and any other metal in or near water. This is required to
address Electrical Shock Hazards.
• Design the suction piping so there are no single-point suction hazards; single-point suction (one drain) is a
leading cause of Body Suction Entrapment Hazards. Note: your certified builder has many effective options for
addressing this hazard; they may include dual-drain systems, like MDX-R3, skimmers, gutters, negative edge
features and many more products and piping designs known to professionals.
• Install ANSI/APSP/ICC-16 2017 listed drains, suction covers and debris removal systems. This is the ONLY
approved option for preventing Hair Entrapment Hazards, the leading cause of suction related injuries.
• Design and install an effective circulation system (including optional cleaning systems), to direct filtered water
to all areas and interior surfaces. NOTE: Suction fittings can NOT clean or direct filtered water for proper
sanitation; that can only be done on the pressure (return) side of the filtration system.

While suction injuries are extremely rare, drowning and diving injuries are far too common and there is little your
certified builder can do to eliminate these hazards. You must educate yourself and your guests. Below are some
important safety issues every swimmer must know and recognize.
• PREVENT DROWNING: Watch children at all times, no swimming alone.
• NO DIVING IN SHALLOW WATER: You can be permanently injured.
• PREVENT SUCTION ENTRAPMENT: Inspect suction covers before swimming, keep swimmers away from
suction fittings, protect long hair, don’t swim with loose clothing or large and dangling jewelry.
For more information about the Virginia Graeme Baker Pool and Spa Safety Act, contact the Consumer
Product Safety Commission at [phone] or visit www.cpsc.gov.
Always turn off all power to the pool pump before installing the cover
or working on any suction outlet.
WARNING
• Cover/Grates and all other SOFA components shall be replaced at or before the end of their service
life. Service life begins the month and year in which the SOFA is installed with or without water. See
parts breakdown at end of this manual for specific component service life notations.
• Any SOFA component that is severely faded, chalking, or brittle when flexed shall be replaced even if it
has not reached its indicated service life.
• If the sump/mud ring or any screw receptacle is stripped, cracked or broken that component must be
replaced.
• Any SOFA component held in place by the pool finish or concrete substrate that becomes cracked
or broken; the material that holds it must be stripped from around the SOFA and new components
“mudded” in place. The surface substrate must be free of deterioration and voids.

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.
MDXR3 is a blockable SOFA and must be installed only as a multiple SOFA system as described in this
installation manual.
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). This VGBA
Suction outlet has an installation specific flow rating and this product
SHALL NOT be installed on a pumping system that is capable of exceeding this limit, which varies
based on the number and location of installed suction outlets. READ and FOLLOW the section
of the included installation instructions explaining how to calculate the suction system flow ratings
and that of the installed pumping system.
WARNING
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.

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.
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 three (3)
feet 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 2" 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.

The SDX2 High Flow Safety Drain® installed
in a concrete shell utilizes a small cutout in the
concrete to form the sump which is sometimes
made of plastic or fiberglass. This concrete sump
provides superior shell strength by eliminating the
large hole associated with plastic sumps. The
water seal is formed against the suction pipe in the
same way a water tight seal is formed with return
pipes. The concrete cutout is typically eleven (11)
inches wide, by two (2) inches deep, with a finger
size cutout around the pipe to allow room for a
watertight seal. (Fig. 3)
Rebar Steel (Fig. 5)
Concrete reinforcing steel should be kept 3" away
from all pipe and fittings.
Concrete Shell Sump (Fig. 3)
Form a concrete sump around each suction pipe.
Concrete Shell Preparation (Fig. 4)
Prior to installing the interior finish, cut each SDX2
riser pipe approximately 1" behind the concrete
shell’s surface.

SDX2 CONCRETE INSTALLATION
Suction Safety
Standards require
that main drain
grates used to cover concrete sumps, must
have the suction pipe cut at least 1 ½ times
the pipe diameter behind the drain cover. This
is to allow room for even water flow through all
drain cover holes. This is not necessary with
the SDX2 drain because the Patented Design
provides uniform suction regardless of pipe
location. However, if the pipe is too close to
the surface, it may restrict water flow to the
pump, reducing hydraulic efficiency, but this
does not pose a suction safety hazard.
