6. Installation
6.1 Installation requirements
1. Ensure that water does not enter the
terminal box during the installation process.
2. DO NOT START THE PUMP until the
system has been filled and checked for
leaks.
3. Do not use the pump to vent the system.
4. Never let the pump run dry. The bearings
require water lubrication and will be
damaged otherwise.
5. Fill system with water. This will result in
immediate lubrication of the bearings.
6. Thoroughly clean and flush the system prior
to pump installation.
7. Operate the pump for 5 minutes, when
controller installation is complete, to purge
remaining air from the bearing chamber.
This is especially important when installing
the pump during the off-season.
8. When making pipe connections, be sure to
follow the pipe manufacturer's
recommendations and all code requirements
for piping material.
6.2 Mechanical installation
6.2.1 Preferred pump and terminal box
orientation
Arrows on the side or bottom of the pump
housing indicate direction of flow through the
pump.
The pump must be installed with the motor shaft
positioned horizontally. Under no circumstances
should the pump be installed with the shaft
vertical or where the shaft falls below the
horizontal plane. See fig.

Terminal box orientation
6.2.2 How to change terminal box position
How to change terminal box position:
1. Remove the four (4) hex socket head screws
(4 or 5 mm wrench) while supporting the
stator (motor).
2. Carefully separate the stator from the pump
housing and rotate it to the correct terminal
box orientation.
3. Replace the hex socket head screws and
tighten diagonally and evenly (7 ft.-lb. torque).
4. Check that the motor shaft turns freely.
Remove the large screw in the middle of the
nameplate, insert a small flat-blade
screwdriver into the end of the shaft, and
turn gently.
5. If the shaft does not turn easily, repeat the
disassembly/reassembly process.
Caution
Consult pipe manufacturers for
material selection before installing
this pump. Absence of pumped
liquid may damage some piping
materials.
Caution
Thoroughly clean and flush the
system prior to pump installation.
Caution
For indoor use only.
Warning
If the terminal box position needs
to be changed, ensure that the
power supply is turned off and
close the isolating valves before
removing the hex socket head
screws.
