Pressure Tank - Franklin Electric Inline 1100 Manuel Du Propriétaire

Refer to the included Inline System's performance tables
(Appendix 1) and friction loss tables (Appendix 2) to
determine the amount of head lost for a given application.

The Inline System needs a small pressure tank placed on
the pump outlet to maintain constant pressure. The tank
supplies water while the pump ramps up to speed and
in circumstances where only a small amount of water is
required for a short period of time. In addition, the tank
prevents water hammer by acting as a system buffer. This
buffer also helps to prevent pressure spikes when there is
a sudden change in demand.
For 12 gpm (45 LPM) fl ow or greater, minimum pressure
tank size is 4 gallons (15 L); for 12 gpm (45 LPM) fl ow,
minimum pressure tank size is 2 gallons (7.5 L).
Pressure Tank Pre-charge (PSi)
The pressure tank pre-charge setting should be 70% of
the system pressure sensor setting as indicated in the
preceeding table.
NOTe: Check tank pre-charge regularly to maintain
optimum pressure regulation.

Hazardous voltage can shock, burn or
cause death.
C A U T I O N
Improper wiring can result in permanent
damage to the system. Pump connection must comply
with National Electric Code (NEC) or Canadian Electric
Code (CEC), and all applicable local codes.
C A U T I O N
If you are not sure of the proper electrical
connections, employ a competent electrician for the
installation. This ensures the installation complies with all
noted electrical codes.
Disconnect power at electrical panel before making
any electrical connections. Supply voltage must be
+/- 10% of Inline System nameplate voltage (230V).
Low or high voltage can damage the Inline System and
will void the warranty. Connect pump to dedicated branch
circuit with no other appliances on it.

4. Install inlet and outlet plumbing and pressure tank as

shown in Figure 2. A check valve must be installed
42
in the inlet and outlet plumbing. The outlet check valve
46 should be between the pump and the pressure tank to
prevent the possibility of backfl ow in to public water
49
systems, and to ensure proper system operation. The
53
inlet check valve should be used when no other backfl ow
56
prevention device is present. This inlet check valve
should be installed before the optional bypass loop if that
plumbing is used. Be sure to check all local plumbing
codes to ensure that all requirements pertaining to
backfl ow prevention are met.
5. Install the pressure sensors at the pressure tank tee
downstream of the pressure tank. (The pressure tank
should be between the pressure sensor and the pump.)
The pressure sensor has a 1/4-18 National Pipe Thread
(NPT) connection. The pressure sensor should not be
installed in an inverted orientation (upside down). Make
sure the pressure sensor and tank are not located more
than 5 feet off the main piping.
6. Install a pressure relief valve downstream of the check
valve. The discharge must be plumbed to a drain rated for
maximum pump output at relief pressure setting.

relief valve able to pass full pump fl ow at 100 PSI
(6.9 bar). Install the pressure relief valve near the
pressure tank.
