Franklin Electric INLINE 400 El Manual Del Propietario página 18

What is the maximum output pressure?
The Inline will maintain a "NO-FLOW" system pressure equal to the incoming pressure (psi) plus the shut-off pressure from the pump operating curve.
For example, if the input pressure is 38 psi, at shut off the system will boost an additional 55 psi. This means ALL plumbing downstream of the Inline
would be subject to maintaining 93 psi (38 + 55). If this high pressure is undesirable due to the condition and/or configuration of the existing plumbing
or appliances, installing a PRV on the discharge of the Inline is recommended to limit the maximum distributed pressure.
What is the maximum operating temperature of the Inline?
The Inline is equipped with two temperature sensors. One is installed integral to the motor to protect the motor windings. The other is installed in the
control head and senses the internal temperature of the water. In both cases, the unit will fault at a max temp of 120 °F and turn back on when the
temperature drops below 95 °F.
Do I have to install the Inline vertically?
The Inline can be installed horizontally as long as the discharge port is directed upwards. This orientation places the air bleed valve in the upward
position, allowing it to function properly during the initial priming of the pump.
How do I prime the Inline system?
The Inline will need to be properly primed before initial operation (before unit is plugged in). Because there are two spring-loaded check valves
integrated into the Inline head, a small amount (1.5 psi) of positive water pressure is needed to open these valves and properly prime the unit.
With the unit fully plumbed into the system, open the water supply valve and allow pressurized water to flow through the unit. You will probably want
to place a small bucket under the Inline tank to capture water that is expelled from the unit during priming. With a small flathead screwdriver, slowly
open the air bleed valve (located directly under the outlet) to allow air to exit the internal pump and tank. When the valve stops sputtering and only a
fine stream of water is being expelled, close the air bleed valve. The unit is now primed and ready for operation.
NOTE: Do not open the air bleed valve when the pump is running.
Can the Inline system be used in suction-lift applications?
It is not recommended to use the Inline in suction lift applications greater than five feet lift. A secondary pressurized water source (i.e. hose from
municipality or 3' riser pipe) may be required in order to provide adequate pressurized priming as described above.
