3. Inlet Pressure Requirements
The amount of pressure required at the inlet of the pump is a
function of the temperature of the water as shown in Table 2B.
In a pressurized system, the required inlet pressure is the
minimum allowable system pressure.
In a system open to the atmosphere, the required inlet
pressure is the minimum distance the pump must be
located below the lowest possible water level of the water
source (tank, pool, etc.).
Installation
Position of terminal box:
Proper installation of the pump
will have the terminal box located to one side of the pump
or the other, with the conduit entry down. See Figure 3A.
If the terminal box position needs to be changed, it is
best to do so before installation. However, if the pump
is already installed, ensure that the electrical supply is
turned off and close the isolation valves before removing
the Allen screws.
To change terminal box position:
1. Remove the four (4) Allen screws (4 or 5mm
wrench) while supporting the stator (motor).
2. Carefully separate the stator from the pump
chamber and rotate it to the correct terminal box
orientation.
3. Replace the Allen screws and tighten diagonally and
evenly (7 ft.-lb. torque).
4. Check that the impeller turns freely. If the impeller
does not turn easily, repeat the disassembly/
reassembly process.
