Unpacking And Inspection; System Assembly - Pentair EVERPURE MRS-350BL Manual

noteS:
• Please read this manual prior to installing and operating the
system.
• Incoming water supplies that do not meet these requirements
may need additional pre-treatment prior to the system. System
performance may be affected if requirements are not met,
including system output production and cartridge change-out
frequency.
• If the supply pressure exceeds 80 PSI, install a pressure reducing
valve. Adjust the pressure reducing valve to the required
operating pressure, not to exceed 80 PSI.
• Consult with your local building inspector for approval and
required permits to install this system. Additional equipment, such
as back-flow prevention devices, seismic restraint equipment, air
gaps, etc., may be required. Completed installation must meet all
local and national codes.
Do not connect the MRS system after any water filtration system,
unless specifically provided for use with the MRS.

unPackIng and InSPectIon

The MRS includes all the necessary fittings for installation. Lengths
of 1/4" tubing have been provided for connecting to the wastewater/
drain connection. Supply lines and distribution piping/tubing are not
included.
The MRS system is packaged as a complete unit in two cartons. At a
minimum, you should have the following:
carton 1 -
Plate Mount Processor Assembly Including:
A. Pump system
B. Cartridge heads
C. Transformer, pressure switch & gauges
carton 2 - cartridge kit including:
A. 6TO-BW or 7TO-BW cartridge
B. MR-100, 225 or 350 RO cartridge
C. 7CC-BW Calcium carbonate (CC) cartridge (optional), or
BW 4400 Cartridge (optional)
Inspect the cartons for damage. Report any damage to freight
carrier immediately. Carefully unpack each item. Save the packaging
material temporarily, as it may be used to protect painted surfaces
during assembly.

SySteM aSSeMbly

The MRS is configured as a two piece unit; with the processor
mounted on a vertical surface and the storage tank located nearby.
Locate the system in an area that is convenient to the inlet water
supply and drain facilities, with access for routing the product water
tubing/piping to the equipment. Install in a dry location, away from
all forms of corrosive and/or flammable materials. Consider ease of
access for servicing when selecting a location.
Processor assembly Mounting
1. If the optional Pre-filter has been supplied, go to step to 2. If not
supplied, go to step 5.
2. Position the MRS processor assembly so the rear of the
mounting plate is accessible. Secure the wing bracket to the rear
of the mounting plate as shown Figure 1. Use the 5/16" hex bolts
and washers provided. Align the wing bracket so it is inward
and upward as far as possible – use a combination square to
maintain alignment. Tighten both bolts securely.
3. Attach Pre-filter head to Pre-filter bracket with 5/16" hex bolts,
nuts and washers provided.
4. Insert elbow fitting into solenoid valve inlet. Connect 3/8" OD
tubing between pre-filter outlet and elbow fitting on solenoid
valve.
5. The processor framework has 6 mounting holes (3 keyhole
slots, 3 standard) on 5.5" centers for securing to a stationary
vertical surface. Evaluate the mounting surface for its ability
to properly support the weight of the processor when in
operation (Approximately 40 pounds).
