INSTALLATION INSTRUCTIONS

Install the JT-2P Positive Pressure Leak Sensor or

JT-2V Positive Vacuum Leak Sensor on the tank

interstice riser. All other tank ports must be sealed

with #150 class pipe fittings.Teflon paste type

sealer is suggested for all threaded joints.

Provide electrical conduit, two each #18 AWG

wires to sensor input terminals of the Models

X76S, X76VS, X76LVC, X76LVCS, X76ETM, or

X76CTM tank monitors. Contact the brown and

blue sensor wires (N.O. position). Intrinsically safe

wiring must be in a dedicated conduit only. No 115

Vac or other wiring is allowed in the same conduit.

Pressurize the tank interstice with compressed air

or nitrogen, (DO NOT USE OXYGEN), or evacuate

the tank interstice through the JT-2P or V fill and

relief valve manifold (provided with the sensor) to

2.9 psig or 10 inches Hg.When the pressure or

vacuum has been applied, the system alarm will

return to normal.

NOTE: When filling the tank annulus with com-

pressed air or nitrogen, the sensor fill and relief

manifold MUST be used. Never exceed 3 psig or

the tank warranty may be void.

WARNING: The red wire, (N.C. position) MUST be

capped off to prevent a short circuit to ground.
