Connect thermostat (black and white leads in control cable)
in series with magnetic starter operating coil so that in case
of overheating, pump will shut down. Failure to connect ther-
mostat circuit voids warranty.
Connect red lead of leak detection circuit to leak detection
probe. Green lead is connected to pump case; connect it to
ground or neutral side of indicating circuit. Either connect
seal leak detection circuit (red and green wires in control
cable) to an indicating circuit in control panel (to show seal
failure) or monitor circuit with an ohmmeter periodically. A
drastic drop in resistance across detection circuit indicates
seal failure.
MOTORS
Single Phase: NEMA design L or M with class B insulation.
Suitable for operation in liquids with a maximum temperature
of 40°C (104°F).

Single phase units
that are not installed
with Sta-Rite control
panels require a
capacitor/overload
package. Purchase
the package through
the Sta-Rite catalog.
