The Oil Smart Pump Switch, when combined with a non-auto sump pump, will allow water to be pumped without the risk of pumping oil. The switch is ideal for elevator sumps, transformer containment areas, parking garages, and city underground vaults

1. Oil Smart Pump Switch
Installation Manual
Oil Smart® Pump Switch:
The Oil Smart® Pump Switch is a stand-alone pump
Controller; it will operate any pump up to 1HP. It is an
industrial grade switch that differentiates between oil
and water used to control pumps in elevators, transformer
oil containment areas, underground vaults, marine,
and other applications. The Oil Smart Switch can be
an integral part of the pump assembly or a stand alone
component wired to the pump or a control valve. Since
1995, the Oil Smart Switch has been the reliable choice
for safely pumping water. Installation of the unit allows
you to comply with State and Federal regulations while
reducing the risk of adverse publicity, fines and expensive
cleanup costs.

2. Preventive Maintenance:
The Oil Smart® Pump must be kept clean. If the switch
is submerged in water during initial installation, it must
be cleaned. Clean with a rag and household rubbing
alcohol or kerosene. Consistent inspection and
preventive maintenance ensures longevity and proper
operation of component.
Operation:
Oil Smart Switch Installation:
Caution: Remove any float switch that is currently in
use or supplied by pump manufacturer. If pump has
manual/auto set, switch to manual.
1. Branch circuit protection shall be provided by
the installer; it must be sized according to
pump/motor specifications.
2. Mount Oil Smart Pump Control panel with
enclosed mounting hardware to pump discharge
pipe. The off sensor of the Oil Smart Switch
shall be positioned at least 3” above the
impeller of the pump.
When water comes in contact with the short (on)
sensor, the pump will turn on. The pump will remain
on until water clear the long (off) sensor. If oil comes
in contact with the on sensor, the pump will not turn
on; however the pump switch will activate and pump
water from under the oil.
Testing:
Place your thumb on the short sensor of Oil Smart®
Pump Switch and the pump will turn on. While touching
the short sensor, touch the long sensor “off” with your
fingers. Remove your thumb from the on sensor and
begin to move your fingers down the off sensor. Remove
your fingers from off sensor and the pump will turn off.
OR Fill up sump area with water, when water reaches
the on sensor, the pump will turn on and remain on until
water clears the off sensor.
