Pneumercator LC1000 SERIES - Leak Sensor Installation - Steel Tanks

LC1000 INSTRUCTION MANUAL INSTALLATION DETAILS

EXTERNAL LEAK SENSOR INSTALLATION
The interstitial or double-wall space of steel tanks and vaulted tanks as well as many other secondary
containment areas can be fitted with leak sensors. Switch actuation may be factory set for either
NORMALLY OPEN or NORMALLY CLOSED.
2.3 LEAK SENSOR INSTALLATION IN STEEL AND VAULTED TANKS
Check the specific design drawings for the job, or use the LS600LD Series as illustrated in Figure
1-5. Install sensor per Figure 2-3 as follows:
1. Remove the watertight CORD CONNECTOR supplied by sliding it off the sensor cable.
2. Thread the watertight CONNECTOR into the top of a 2" by 1/2" reducer bushing or monitor pipe
cap pre-tapped for a 1/2" NPT hole. (The use of any standard monitor cap from 2" to 4" pipe size
is recommended. The cap or reducer bushing IS NOT SUPPLIED with the sensor and must be
provided by the installer. A 2” (SK2) or 4” (SK4) Sensor Cap Kit can be ordered separately from
Pneumercator).
3. Measure the "MOUNTING HEIGHT" from top to bottom of monitoring pipe.
4. Feed the sensor cable through the watertight CONNECTOR from the BOTTOM SIDE of the
REDUCER (or CAP) fitting to a cable length suitable for the MOUNTING HEIGHT; or to allow
sensor to rest on the monitor pipe bottom; or as required by local codes. Cable may be cut or
extended to proper length.
5. Re-tighten the CORD CONNECTOR to fix the sensor cable length.
6. Mate the REDUCER or CAP to the top of the monitor pipe. Tighten the CONNECTOR to ensure
a WATERTIGHT SEAL.
7. Route the sensor cable to the junction box and complete the wiring installation in accordance with
Section 3.
