1. MDX-R3 INSTALLATION PROCESS NON-ADJUSTABLE CONCRETE POOLS

2. MDX-R3 Installation NON-ADJUSTABLE CONCRETE POOLS
SUBMERGED SUCTION OUTLET
FOR MULTIPLE DRAIN USE ON FLOOR |

3. Notice:
Warning: MDX-R3 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.
These instructions provide two methods to choose from with an additional method for specific jurisdictions, (California specifically but not limited to that state). Your local codes may require additional safety measures. Paramount 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, many modern pumps are 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). 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.
For technical assistance call or contact your regional representative. |

4. Maximum GPM = 132 (500 LPM) Velocity at 132 GPM = 1.294 FPS (.39 MPS)
System Design
Plumbing of the included enlarged suction element (13” of 4” pipe) to the center port of the MDX-R3 is required.
After the enlarged suction element, the included reducer adaptor 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 adaptor with the MDX-R3. (The 2 ½” tee is not included in the MDX-R3.)

Position the top edge of the MDX-R3 sump even with the finished depth of the pool, spa, or a basin. Finish concrete to bottom edge of construction cap. Orientate the sump so the elbow is perpendicular to inside wall or end wall of pool.
When using one MDX-R3 in the floor position the REQUIRED SDX High Flow Safety Drain® on a sidewall of the pool below water level. (If pool will be winterized, place the SDX high enough to reach from the deck.) The SDX will be teed into the main suction line as close to the reducer adaptor as possible. See installation method 1. In California the drains will be plumbed with equal size and length pipe from the tee to each drain. See installation method 1 California.
When using two MDX-R3s in the floor of the pool connect them together with the supplied enlarged suction elements and thru the 4” tee then use the reducer in the side port of the tee if required. See installation method 2. (4” tee is only included in the a two pack MDX-R3) |

10. Concrete
To allow the sump to be fully encased in concrete, clear dirt to completely expose the sweep elbow.
Pack concrete around and under sump to ensure seal and strength of shell.
Angle shell down to MDX-R3 sump water stop flange.
Make cut-out around MDX-R3 sump. 17¼” round by ¾” deep down to water stop. |

11. Plaster Plaster to top edge of the sump.
Pack plaster around water stop. |

12. Final Assembly Assemble the drain PRIOR TO ADDING WATER
Remove 4” pressure plug (#7).
Make sure that funnel adaptor (#4) is snapped onto funnel assembly (#3).
Install funnel assembly (#3) into sump (#5) and secure with 4 (four) security screws (#2) with a screw driver Torx T25.
Install the cover (#1) onto the funnel assembly (#3) and secure with 3 (three) security screws (#2). |
