DESCRIPTION
The OS3 oil-sensing sump system is designed and approved for
the safe pumping, alarming, and monitoring of elevator sump pits,
transformer vaults, and leachate wells. The OS3 will activate a pump
to remove water from elevator pits in accordance with ASME A17.1.
Remote alarm has additional
auxiliary contacts for building
alarm system.

The OS3 stops the pump before oil or other harmful substances
enter the water supply. Indicator lights will illuminate on the control
panel for the following: power, pump running, high alarm, high
oil, and pump overload (optional). The panel has a set of auxiliary
contacts that activate on power loss or high oil/water conditions.
These contacts can be connected to the OS3 remote alarm panel,
which contains audio/visual alarming along with auxiliary contacts
for connection to building automation system or SCADA system.
When the water level rises to the START probe, the pump turns on.
The pump remains on until the water level drops below the OFF
probe. The OFF probe senses air or oil and turns the pump off so
the oil layer will not be pumped out of the sump. If the liquid level
reaches the ALARM probe and HIGH-LEVEL float, the system will
differentiate between water and oil and activate the remote alarm.
WARNING: RISK OF ELECTRICAL SHOCK. PLEASE OBSERVE
THE FOLLOWING SAFETY GUIDELINES.
WARNING: Installation of the system must comply with all federal,
state and local codes, regulations and practices.
The system must be installed by qualified personnel familiar with
all applicable local electrical and mechanical codes. Refer to
BEFORE
the national electrical code (NFPA 70). Failure to properly install
SERVICE
and test this product can result in personal injury or equipment
malfunction.
Do not use with flammable or explosive fluids such as gasoline, fuel
oil, kerosene, etc. Do not use in explosive atmospheres.
Use probe/float switch with water only.
Do not handle the system with wet hands or when standing on a wet
or damp surface or in water.
Disconnect all electrical service before working on or handling the
system.
Ensure that the incoming voltage matches the system voltage.
To prevent electrical shock and equipment malfunction, use only
with a pump supplied with a grounding conductor and grounding-
type attachment plug. Be certain to plug the OS3 panel into a
properly grounded, grounding-type outlet.
Mount the control panel and alarm indoors. Consult the manufacturer
for outdoor applications.
Use caution with models that use an overload relay. The pump
motor may start immediately when the overload is reset.
Secure the level sensor on a discharge pipe at a level that guarantees
partial pump submergence when water level is just below the OFF
probe. Failure to properly mount the level sensor may cause the
pump to activate even when oil is present in the sump.
