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.
The MDX² Anti-Entrapment Debris Drain is only available to certified contractors for the same reason certified
electricians are required to connect filtration pumps to public utilities; both require proper training and certification to
assure no hidden hazards are built into the project.
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 azards.
• 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 azards. Note: your certified builder has many effective options for addressing
this hazard; they may include dual-drain systems, like MDX², skimmers, gutters, negative edge features and many
more products and piping designs known to professionals.
• Install ASME A112.19.8 - 2007 listed drains, suction covers and debris removal systems. This is the ONLY approved
option for preventing air Entrapment azards, 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 S ALLOW 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.
WARNING: MDX² and SDX must be installed in accordance with Paramount's written instruction manual, and in
conformity with applicable Federal, State, Local and Swimming pool industry building and safety codes.

MDX² RETR INSTALLATI N MANUAL

N TICE — Maximum Pump Size:
MDX² Retro is rated for a maximum of 90 GPM (340 LPM). While system flow rate will vary with pump size and the
Total ead 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 (340 LPM). 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:
When replacing the MDX Cover and Funnel Assembly with the MDX² Retrofit cover D N T disable the secondary
drains or the third layer of protection. The third layer of protection may be another submerged drain or a vent tube. If
you do not have a third layer of protection on this system then you will need to add an SVRS or cut the floor of the
pool and add a SDX drain teed into the main suction line 3’ 10” minimum from the MDX. When replacing the MDX be
sure to check all other submerged suction outlets in the pool for broken or missing covers, correct or missing screws
and compliant covers. Be sure to replace these covers with a SDX or SDX retro covers to bring all suction outlets into
compliance.
D N T INSTALL THE MDX2RETR UNLESS THERE IS AN MDX SUMP AVAILABLE T ACCEPT THE

Hydrostatic Fitting
The hydrostatic port inside the MDX² Sump is equivalent to a 2" Threaded Female Adapter and a 2" Slip Fitting
Outside the MDX² Sump. 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. This port is
for the purpose of a hydrostat only. Do not install any suction equipment (pump) to this port

2. If 3rd suction line is installed remove grate, install a 13-
¾ blow-through plug and blow line to achieve airlock.
3. Go to canister instructions step 1 - 4 below.
4. If vent tube is installed, install blow through plug and
blow line to achieve airlock. Repeat vacuum out

If vacuum relief suction outlets are located below freeze
line skip steps 1 and 2.
1. Remove grate from second suction and install a
13-¾ blow through plug and blow line to achieve airlock.
2. If 3rd suction line is installed remove grate, install a 13-

3. If vent line is installed in main suction line, plug vent line
and install blow through plug in pump inlet and blow
line to achieve airlock.
4. Lastly, blow vent line to achieve airlock.
VENT TUBE WARNING LABELS (Figures 8 and 9)
Included in each MDX² are two warning labels that need
to be placed on the pool equipment if the pool is to be
winterized and has a vent tube on any of the drains
plumbed on the pool. Attach the smaller label to the vent
pipe where it terminates to atmosphere. (See Fig. 8)
Attach the larger label to the control panel next to the
controller for the pump with the vent tube plumbed to it.
(See Fig. 9)
1. Remove outer lid, inner lid and basket, clean and
dry off, and store in same area as modules
2. Install and secure regular winterization plug in
equalizer line of canister to pool at poolside.
3. Install and secure Schrader plug or blow out plug
from canister to main drain. Blow out and obtain air
lock as previously described, if skimmer is tied into
canister, repeat procedure to skimmer.
4. Bottom port of canister to pump may require an
extended pipe for ease of blowing out. Install and
blow out line from canister to pump. Install and
secure plug in pump. Using a wet/dry shop vac,
remove all water from within canister components.
5. Extension pipe can be removed and replaced with
plug or Gizmo type container if Gizmo not used. Be
sure to install device to absorb ice expansion in
canister area. Failure to do this may result in
potential ice freeze damage to canister.
