Operation and Maintenance Manual

Introduction

Read all instructions thoroughly. Installation of the OilTector must comply with all Federal, State and Local Codes, Regulations
and Practices. The OilTector must be installed by qualified personnel familiar with all applicable local electrical and mechani­cal codes. Refer to the National Electrical Code (NFPA 70). Failure to properly install and test this product can result in
personal injury or equipment malfunction.

The OilTector control system is designed and approved for the safe operation of pumping, alarming and monitoring of elevator
sump pits, transformer vaults and leachate well applications. The OilTector will activate a pump to remove water from elevator
pits in accordance with ASME A17.1. The OilTector stops the pump before oil or other harmful substances enter our water
supply. Indicator lights will illuminate on the control panel for the following: power, pump running, high alarm, high oil. 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
OilTector remote panel which contains audio/visual alarming along with auxiliary contacts for connection to building automation
system or SCADA system. The recommended minimum sump size is Ø18” x 30” high.

Safety Guidelines

1. DO NOT USE WITH FLAMMABLE OR EXPLOSIVE FLUIDS SUCH AS GASOLINE, FUEL OIL, KERO­SENE, ETC. DO NOT USE IN EXPLOSIVE ATMOSPHERES. PROBE/FLOAT SWITCH SHOULD
ONLY BE USED WITH WATER.

2. DO NOT HANDLE THE OILTECTOR SYSTEM WITH WET HANDS OR WHEN STANDING ON A WET
OR DAMP SURFACE OR IN WATER.

3. DISCONNECT ALL ELECTRICAL SERVICE BEFORE WORKING OR HANDLING THE OIL ALERT
SYSTEM.

4. INCOMING VOLTAGE MUST MATCH OILTECTOR SYSTEM VOLTAGE.

5. 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 OILTECTOR PANEL INTO A PROPERLY GROUNDED, GROUNDING-TYPE
RECEPTACLE.

6. CONTROL PANEL AND ALARM MUST BE MOUNTED INDOORS. FOR OUTDOOR APPLICATIONS
CONSULT FACTORY.

7. SECURE LEVEL SENSOR ON DISCHARGE PIPE AT A LEVEL THAT GUARANTEES PARTIAL PUMP
SUBMERGANCE WHEN WATER LEVEL IS JUST BELOW THE “OFF” PROBE (THE LONGEST
PROBE). (See Figure 5 on page 3 of this manual). FAILURE TO PROPERLY MOUNT THE LEVEL
SENSOR MAY CAUSE THE PUMP TO ACTIVATE EVEN WHEN OIL IS PRESENT IN THE SUMP.

8. CAUTION! REMOVE ANY FLOAT SWITCH THAT IS CURRENTLY USED OR SUPPLIED WITH THE
PUMP. IF THE FLOAT CANNOT BE REMOVED, SECURE SWITCH SO THAT IT IS ALWAYS ON.

Operation and Maintenance Manual

Operation and Maintenance Manual

Description of Operation

On water rise, level reaches pump “start” probe to start the pump. Pump will remain on until level is below
“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 alarm probe and mechanical float, the system will differentiate between
water and oil and activate the remote alarm.

Installation of the Control Panel

1. It is highly recommended to mount the control panel in the same area as the sump pump to eliminate any
splicing of sensor and pump wires. See “Installation of Preset Level Sensor Holder” for more information on
splicing.

2. Determine mounting location for the control panel. Mount panel at the desired location making sure the
mounting location of the control panel is within 6 feet of electrical receptacle.

3. Plug pump cable into control panel receptacle cable. Plug power cable into receptacle only when ready for
testing. See Testing System installation.

4. If the panel is to be installed with conduit, the cables and cord seals must first be removed. Please make
note of wire locations. The incoming power 115V is connected to L1 and L2 of the contactor, pump receptacle
is T1 and T2 on the contactor. Low voltage cable from the level sensing module: green - TB1 off probe,
yellow - TB2 start probe, red - TB3 alarm probe, white - TB4 float, black - TB5 float. Low voltage auxiliary
contacts are TB6 and TB7. Do not mix low voltage probe wires or auxiliary contacts in high voltage conduits.
See figure 3 and figure 6.

Warning – Do not mix high and low voltage circuits in the
same conduit, failure to do so will cause system malfunc­tion. The Preset Level Sensor and Auxiliary
Contact wires are low voltage class 2 circuits

- Do not install sensor cables in conduits
with main power or pump cables.
