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 horizon-
tal plane (Fig. 4C)
.

Installation
Requirements
•
Thoroughly clean and flush the system prior
to pump installation
•
Ensure that water does not enter the terminal
box during the installation process.
•
DO NOT START THE PUMP UNTIL THE SYSTEM
HAS BEEN FILLED AND CHECKED FOR LEAKS.
•
Do not use the pump to vent the system.
•
Never operate the pump dry. The bearings
require water lubrication and will be dam-
aged otherwise.
•
Fill system with water. This will result in
immediate lubrication of the bearings.
•
Operate the pump for 5 minutes, when
control installation is complete, to purge
remaining air from the bearing chamber. This
is especially important when installing the
pump during the off-season.

Electrical
Provisions for a 115 V grounded outlet within 6
feet of the pump mounting location, should be
made.
All electrical work should be performed by a qualified
electrician in accordance with the latest edition of the
National Electrical Code, local codes and regulations.
All speed control signal wiring terminates in the
wiring chamber on the control. All field installed
wiring should meet or exceed requirements for
class 2 wiring per article 725 of the National
Electrical Code rated at 30VAC/250VA.
Test the Speed Control Signal Wiring.
Make sure exposed wires and bare terminals are
not in contact with other wires or grounded
surfaces. Turn on the control signal and measure
the voltage/mA across the leads using a voltmeter
to confirm the pump signal is present.
Electrical Connections To The Control
CAUTION:
The installer should confirm that no
current/voltage is present at any of the wires.
Current Speed Control Signal Connections:
Connect the current signal wires to terminals
"Com(-)” and “DEM/I” (Fig 6A. ).
Voltage Speed Control Signal Connections:
Connect the voltage signal wires to the “Com (-)”
and “Out/V” terminals (Fig. 6B).
Note: Control signal wires must be run through and
secured by the stain relief on the terminal board.
Note: No speed control signal is necessary if speed
is to be regulated using the manual % dial.
