FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING . For single
phase pumps supplied with a grounded plug, DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE GROUND PIN. The plug must be inserted
into a mating grounded receptacle. If the installation does not have such a receptacle, it must be changed to the proper type, wired and grounded
in accordance with all applicable local codes and ordinances.
All three phase pumps require motor starting devices with motor overload protection. Three phase pumps
must be installed in accordance with all applicable
local codes and ordinances. Pumps are not to be installed in lo
Risk of electrical shock. Do not remove power supply cord and strain relief or connect conduit directly to the pump.
PUMP WIRING INSTRUCTIONS
Single Phase Installation
To operate a non-automatic pump automatically, a control panel or 20 amp
control switch (P/N 10-0748) must be added to the power circuit. Follow
Three Phase Installation
Three phase pumps are nonautomatic. To operate automatically, a control panel
is required. Follow the instructions provided with the panel to wire the system.
Before installing a pump, check the pump rotation to insure that wiring has been
connected properly to power source, and that the green lead of power cord, is
connected to a valid ground, momentarily energize the pump, observing the
directions of kick back due to starting torque. Rotation is correct if kick back
is in the opposite direction of rotation arrow on the pump casing. If rotation
is not correct, switching of any two power leads other than ground, should
provide the proper rotation.
For automatic three phase pumps see automatic 3 phase wiring diagram
located to the far right.
