Checking STPs for leaks
Replacing The WPLLD Sensor
6
4.
Follow the instructions in Figure 2 (above) to connect the WPLLD sensor to the
pump.
5.
Replace the shield into the capacitor housing with open side up. Hold the shield at
an angle and place notched tab into the compartment first. Guide the two wires
from the WPLLD sensor into the notch on the shield, leaving as much slack in the
wires as possible above the shield (this will prevent stressing them when the
WPLLD sensor is threaded into the pump).
6.
Lightly lubricate the O-ring on the WPLLD sensor with mineral oil or other
suitable lubricant.
7.
Rotate the sensor about three turns counterclockwise, then screw the Wireless
Line Leak Sensor into the pump compartment and tighten it securely.
8.
Reconnect the sensing line to the WPLLD sensor and tighten it securely.
9.
With the two 6-32 x 0.375” screws provided, attach the capacitor cover bracket
(removed from the original WPLLD sensor) to the top of the new WPLLD sensor.
Snap the capacitor cover into the bracket.
Checking STPs for leaks
After connecting all of the sensors, apply power to each pump and check for leaks.
Verify that the functional element, sensing lines, and check valve threads into each
pump are not leaking. Product leakage can create serious environmental and safety
hazards.
❑
Tighten any leaking fittings until the leak is stopped. Be careful not to overtighten
and strip the threads. If the leak cannot be stopped, turn OFF power to the pump
and check the fitting for thread damage or improper sealing.
❑
Replace or reseal the fitting(s) as required.
