sure tank (when pump shuts off). This fi gure represents CYCLE TIME.
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 fi gure 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 IMPORTANT NOTE
The addition of other water treatment devices (such as an acid neutralizer) may reduce the fl ow rate at the fi lter drain to an inadequate level to properly
backwash the fi lter. If you are uncertain whether your fl ow rate is adequate, contact your Dealer/Installer or our Customer Service Department at 1-800-
222-7880 BEFORE installing the APPM 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 fl oor 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
fi lters and softeners and will void the factory warranty.
5) Do NOT install a fi ltration 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 suffi cient 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 fl ow switch will describe the
proper installation for these types of applications.
THE IMPORTANCE OF YOUR PRESSURE TANK:
The APPM 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 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 APPM
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 suffi cient ground connec-
tion across the fi lter installation piping — refer installation to qualifi ed personnel.
• Do not use the system if the power cord is damaged — contact qualifi ed service personnel for repair.
If lawn sprinkling, geothermal heating/cooling or water for other devices/activities are to be treated by the fi lter, a larger model fi lter MUST be selected to
accommodate the higher demands of these items. The pumping rate of the well pump must be suffi cient to accommodate these items plus the backwashing
requirement of the softener. Consult your Dealer/Installer or our Customer Service Department at 1-800-222-7880 for alternative instructions if the pumping
rate is insuffi cient.
Remember that the fi lter 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 fi ttings required. Typical
system schematics shown in Figure 1 will be of assistance (page 3-1).
