General Information and Safety
ADDITIONAL EQUIPMENT REQUIRED FOR PROPER OPERATION: Manganese greensand filters require KMn04 (Potassium
Permanganate) to be injected into the feed water stream in order to regenerate the media bed. This is usually done with the use
of a chemical injection system including a chemical tank, mixer and metering pump. This equipment is sold separately and should
be designed and sized for each specific installation. The injection method and concentration of potassium permanganate
required depends on the concentration of iron and manganese in the water as well as other factors. Please contact Applied
Membranes, Inc. for assistance in sizing and purchasing the appropriate chemical injection system.
DISCLAIMER: The information contained in this document is subject to
change without notice. Applied Membranes, Inc. shall not be liable
for technical or editorial omissions made herein; nor for incidental or
consequential damages resulting from the furnishing, performance, or
use of this material.
READ THIS MANUAL: Prior to operating or servicing this unit, this
manual must be read and understood. If anything is not clear, call for
assistance before proceeding. Keep this and other associated
manuals for future reference and for new operators or qualified service
personnel.
CAUTION: Never let the filter freeze. Freezing can damage the
media tank.
USE PROPER POWER CONNECTION methods to satisfy local
electrical codes. SHOCK HAZARD: Connect this unit to a properly
grounded connection in accordance with the National Electrical
Code. DO NOT, under any circumstances, remove the ground wire
or ground prong from any power plug. Do not use extension cords or
an adapter without proper consideration.
SERVICE WARNING: To prevent electrical shock, disconnect
power to the system prior to servicing.
WARNING: Do not make any alteration or modification in the
wiring or plumbing of the system. This can result in damage to the
system and cause injury to operators or users.
WARNING: Flush the system for at least 30 minutes before use to
remove all chemicals present.
Installation
Unpack the filter. Inspect assemblies for damage (cracked couplings, broken or split pipes, loose straps, etc.).
Location
Select a location for the filter with adequate clearance from walls and other equipment to allow access on all sides of the tank.
The unit must be located near a drain able to accommodate the backwash flow rate of your unit (see the table on page 4). This is
in addition to any other equipment sharing the drain.
A grounded power supply of the appropriate voltage and a local disconnect switch is required.
Installation and Service Manual – Manganese Greensand Iron Filter
Situate downstream from the potassium permanganate injection system (see note in general information and safety).
Caution: The unit must not be located near any corrosive chemicals, or in an area where the temperature may
exceed 113F (45C).
Warning: The power supply must be properly grounded to avoid injury from electrical shock.
Loading the Media
If media shipped unloaded (packaged separately outside of the tank) then continue with the loading instructions. If the filter was
shipped loaded, please skip to plumbing.
1. Place tank on a level, solid surface in the correct position for installation. Lift the riser tube from
the tank, keeping the attached hub within the opening of the tank. Within the tank, assemble the
laterals onto the hub, twisting each lateral into the hub to lock securely. Gently lower the
assembly to the bottom of the tank. The top of the riser tube should be about level with the top of
the tank.
2. The „riser tube‰ inside the media/resin tank delivers treated water to your control valve. It will
need to be temporarily covered with tape on the top end to prevent anything from falling down
inside the tube during loading.
3. Step back and look at the tank to make sure it is standing straight, and not tilted. The black base
on the bottom of the tank should also be straightened before filling the tank. If your tank is tilted,
simply pick up the tank 2-3 inches off the floor and drop it gently (but firmly) down, favoring the
side of the base that needs to be adjusted.
4. Before loading the media, fill the tank with 2-3 feet of water (or 1/3 full, depending on the tank
size), to soften the fall of the rocks and prevent damage to the distributor. To load the media, use
a funnel in the top of the media tank with the riser tube still inside. Make sure the riser tube is
covered with tape to keep media out.
5. Scoop the media into the funnel, slowly letting it fall down inside the media tank around the riser tube. Fill the tank with the
w
media provided, pouring the media in the following order (1st
of the tank, etc.).
Note: The tank will be approximately - ⅔ full after loading is complete.

I. Gravel YMGRVL11618 0.5 CF (50 lbs) per bag
II. Manganese Greensand YMMNGS 1 CF (85 lbs) per bag
6. Remove the funnel from the top of the tank, and the tape from the end of the riser tube. Brush any loose media off the top
opening of the tank.
7. The bottom of the control valve has an opening with O-rings inside; lubricate the O-ring with a non-petroleum based lubricant.
Position the valve over the top of the media tank, making sure the top of the riser tube inserts inside the opening in the bottom
of the valve.
8. Screw the valve down into the media tank. Another person should hold the tank as the valve is being snugly tightened onto the
tank. Do not over-tighten. Tighten until snug, tighten a bit more, then STOP. The large o-ring will seal itself.

Plumbing
Note:
Caution:
All plumbing is to be done in accordance with state and local codes.
Before placing wall anchors to support piping ensure that no electrical conduit or wiring is located behind the
intended mounting location.
Note:
The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments but are not
designed to support the weight of a system or the plumbing.
1. Install connecting piping between raw water source and input pipe on
control valve.
The installation fittings connect to the control valve or the bypass valve
using nuts that only require hand tightening. Do not use a pipe wrench to
tighten nuts on installation fittings. The split ring design, incorporated into
the installation fittings allows approximately 2 degrees off axis alignment
to the plumbing system. The installation fittings are designed to
accommodate minor plumbing misalignments but are not designed to
support the weight of a system or the plumbing.
When assembling the installation fitting package, connect the fitting to
the plumbing system first and then attach the nut, split ring and o-ring.
Heat from soldering or solvent cements may damage the nut, split ring or
o-ring. Solder joints should be cool and solvent cements should be set
before installing the nut, split ring and o-ring. Avoid getting primer and
solvent cement on any part of the orings, split rings, bypass valve or
control valve. Solvent cements and primers should be used in accordance
with the manufacturerÊs instructions.
Slip the nut onto the fitting first, then the split ring second and the o-ring last. Hand tighten the nut. If the fitting is leaking
tightening the nut will not stop the leak. Remove the nut, remove the fitting, and check for damage or misalignment of the oring.
Do not use pipe dope or other sealant on threads. Use teflon tape on threaded inlet, outlet and drain fittings. Teflon tape is
not necessary on the nut connection or caps because of o-ring seals.
2. Install drain line from control valve to a free flowing drain.
If the drain line is a ⅝‰ flexible polytube, slide the nut onto the polytube, then place the polytube insert into the end of the
polytube and tighten the nut on to the ‰ drain line fitting. The nut is only designed for use with fexible polytube. Use other
nuts if attaching different materials. (To access the drain line flow control, remove the locking clip by pulling it straight out.
Pull fitting out and replace the locking clip so that it is not misplaced. The drain line fitting is pressed in and has an o-ring
seal.)
3.
4. Install piping between valve output and point of use. The installation fittings connect to the control valve or the bypass valve
using nuts that only require hand tightening.
See step 1 for handling details.
