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 (Fig. 1).
• 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 damaged 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.
