2. With the pressure tank full, draw water into a container of known volume, measure the number of gallons drawn until the pump starts again. This is
DRAW-DOWN. Divide this figure by CYCLE TIME and multiply the result by 60 to arrive at the PUMPING RATE in gallons per minute (gpm). To aid in your
calculation, insert the data in the following formula:
DRAW-DOWN _____ ÷ CYCLE TIME _____ x 60 = PUMPING RATE _____
(gals.) (secs.)
(gpm)
EXAMPLE: CYCLE TIME is 63 secs.; DRAW-DOWN is 8 gals.; then PUMPING RATE equals: 8 gals. ÷ 63 secs. x 60 = 7.6 gpm
IMPORTANT NOTE
The addition of other water treatment devices (such as an acid neutralizer) may reduce the flow rate at the filter drain to an inadequate level to properly
backwash the filter. If you are uncertain whether your flow rate is adequate, contact your Dealer/Installer or our Customer Care Team at 855-3M-WATER
(855-369-2837) BEFORE installing the 3MAPPM Series Iron Reduction Filtration System, so that corrective action, if required, may be taken.
LOCATE WATER CONDITIONING EQUIPMENT CORRECTLY:
Select the location of your media tank with care. Various conditions which contribute to proper location are as follows:
1) Locate as close as possible to water supply source.
2) Locate as close as possible to a floor or laundry tub drain.
3) Locate in correct relationship to other water conditioning equipment (See Figure 1, in Section 3).
4) Filtration systems and softeners (if applicable) should be located in the supply line BEFORE the water heater. Temperatures above 110°F (43.3°C) damage
filters and softeners and will void the factory warranty.
5) Do NOT install a filtration system or softener (if applicable) in a location where freezing temperatures occur. Freezing may cause permanent damage to
this type of equipment and will also void the factory warranty.
6) Allow sufficient space around the unit for easy servicing.
7) If your water source is a community water supply, a public water supply, OR you wish to bypass water used for a geothermal heat pump, lawn sprinkling, out
buildings or other high demand applications, the purchase of an FS1 Flow Switch is suggested. Instructions accompanying the flow switch will describe the
proper installation for these types of applications.
THE IMPORTANCE OF YOUR PRESSURE TANK:
The 3MAPPM Series Iron Reduction Filtration System will perform satisfactorily with either a captive-air (“bladder”) type pressure tank or a standard air-to-
water type with an air volume control (air-relief valve).
A PROPERLY SIZED PRESSURE TANK OF EITHER STYLE WILL REQUIRE A MINIMUM PUMP CYCLE OF 60 SECONDS TO REFILL FROM THE WELL PUMP ON-TO-OFF
PRESSURE SETTINGS.
IMPORTANT NOTE
If your pressure tank (or any part of your water system) is not functioning properly, corrective action MUST be taken BEFORE installation of the 3MAPPM
Series Iron Reduction Filtration System.
FACTS TO REMEMBER WHILE PLANNING THE INSTALLATION:
WARNING
To reduce the risk associated with a hazardous voltage:
• If the home electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure a sufficient ground connec
-
tion across the filter installation piping — refer installation to qualified personnel.
• Do not use the system if the power cord is damaged — contact qualified service personnel for repair.
If lawn sprinkling, geothermal heating/cooling or water for other devices/activities are to be treated by the filter, a larger model filter MUST be selected to
accommodate the higher demands of these items. The pumping rate of the well pump must be sufficient to accommodate these items plus the backwashing
requirement of the softener. Consult yyour Dealer/Installer or our Customer Care Team at 855-3M-WATER (855-369-2837) for alternative instructions if the
pumping rate is insufficient.
Remember that the filter
INLET
is attached to the pipe that supplies water (i.e. runs to the pump) and
OUTLET
is the line that runs toward the water heater
or other water treatment equipment device.
Before commencing the installation, it is advisable to study the existing piping system and to determine the size, number and type of fittings required. Typical
system schematics shown in Figure 1 will be of assistance (page 3-1).
