VPS Installation Tools Required
6
An desiccant tube is recommended for the VPS in wired/wireless vent stack installations (see kit in Table 3).
Tools Required
1. Wrenches suitable for tightening tubing/pipe fittings.
2. Necessary pipe fitter’s equipment (including threading equipment as needed) and a non-hazardous work
space suitable to modify the dispenser vapor line or the vapor vent stack for VPS sensor installation.
3. T25 Torx bit for tamper-resistant screws to secure vent stack enclosure door.
Under Dispenser Installation Steps
1. Before installing this device, turn Off, tag/lock out power to the system, including console and submersible
pumps.
2. Determine which dispenser is closest to the tank/tanks being monitored. Remove that dispenser’s lower
sheet metal doors to gain access to the vapor plumbing.
3. Refer to VPS dispenser installation examples in Figure 1 through Figure 5 to locate a suitable port or plumb a
suitable fitting for the VPS tubing in either the vapor return shear valve or in the vapor return line.
4. Install one of the 68CA-4-4 male connectors (item 2 in Table 1) from the kit into the tapped hole.
5. Install VPS (item 1 in Table 1) vertically to the dispenser frame or piping using the 2-inch conduit clamp,
rubber shim, and necessary bolts, nuts, and washers from the included Universal Sensor Mounting kit. Wrap
the rubber shim (item 10 in Table 1) around the sensor before inserting it into the clamp.
The VPS sensor must be installed in a VERTICAL position with the sensing port pointing
down. Its connection in the base of the dispenser in the vapor return line must be made
BELOW the vapor return line shear valve mechanism, AND BELOW the Air Flow Meter (AFM)
outlet (if an AFM is installed).
6. Attach one end of the 62CA-4 union (item 3 in Table 1) to the pressure sensing port in the base of the VPS.
7. Install the remaining 68CA-4-4 male connectors (item 2 in Table 1) from the kit into each of the three ports in
the 3-way calibration valve (item 13 in Table 1).
8. Measure, fabricate, and install a ¼" OD copper tube (item 12 in Table 1) that runs between the 62CA-4
union in the base of the VPS and the center port of the 3-way calibration valve.
9. Measure, fabricate, and install a ¼" OD copper tube that runs between the ¼" tube end of the male
connector fitting installed beneath the shear valve mechanism and the right port on the 3-way valve, being
careful not to create any potential liquid traps (Note 3-way valve orientation in Figure 5).

10. Screw the 59CA-4 plug, item 4, from the kit onto the left port’s male connector. Make sure the valve’s handle
is set to connect the VPS to the vapor return line and not to the capped (ambient) port.
All plumbing’s pitch to drain should be 1/4” vertical per 12” horizontal to eliminate liquid
traps.
11. Install a cord grip from the kit into a I.S. junction box knockout. Route the VPS cable into the I.S. junction box
and tighten the cord grip. Observing polarity, connect the field wiring from the TLS console to the VPS wiring
with wire nuts (see Figure 6).
For Wireless installations skip Steps 11 - 13. The VPS sensor connects to a TLS RF
transmitter, not to field wiring from the TLS Console (see manual 577013-964 for
instructions).
12. Seal wire nuts in epoxy sealant following the instructions in Figure 7. Push the epoxy sealed bag into the
junction box. Replace and tighten the junction box cover.
13. For TLS-450PLUS console, connect VPS field wiring to a USM module (see Figure 8). For TLS-350
Consoles, connect VPS field wiring to a Smart Sensor Module (see Figure 9).
14. Replace lower dispenser sheet metal doors onto dispensers.
15. After the VPS has been installed, pressurize the tank ullage space and vapor piping to at least 2 inches WC
and test for leaks using leak detection solution.

3. Locate a suitable port in an existing Schedule 40 piping fitting (tee, cross, etc.) or plumb a suitable Schedule
40 pipe fitting (tee, cross, etc.) into the vapor vent stack line (maximum length of copper tubing limited by
dimension in Figure 10).
4. Install the VPS (item 1 in Table 2) vertically onto the center of the composite panel (item 3 in Table 2) using a
2-inch conduit clamp, rubber shim, and necessary bolts, nuts, and washers included in the kit. Be sure the
symbol on the panel is facing upwards (see Figure 11). Wrap the rubber shim (item 22 in Table 2) around
the sensor before inserting it into the clamp. Also make sure the VPS cable outlet is facing up and the
pressure sensing port tube in the base of the VPS is facing down. Locate the VPS in the clamp, but leave the
conduit clamp screw somewhat loose for later height adjustment.
5. Install two169CA-4-4 male elbows (item 4 in Table 2) into each end of the 3-way calibration valve (item 11 in
Table 2) as shown (see Figure 11).
6. Install one 68CA-4-4 male connector (item 5 in Table 2) into the center port of the 3-way calibration valve,
and then directly attach it to the VPS inlet port (see Figure 7).
7. Screw the 59CA-4 plug (item 6 in Table 2) onto the left port’s male elbow (see Figure 11).
8. Install the two plastic enclosure mounting plates to the back of the enclosure. Use the four short flat-head
screws included in the enclosure hardware bag.
9. Install the composite panel into the enclosure (item 2 in Table 2) such that the VPS cable outlet is facing up
and the pressure sensing port tube in the base of the sensor is facing down. The symbol on the panel
should be facing upward. Use the four short screws included in the enclosure hardware bag.
10. Make sure that the white flanged porous vent (factory installed - item 17 in Table 2) is still securely installed
into the hole in the bottom of the enclosure (see Figure 11).
11. Insert the S-bend ¼" OD copper tube (item 9 in Table 2) into the right-side male elbow of the 3-way
calibration valve, but do not fully tighten the compression nut (see Figure 11).
12. Locate the 62CABH-4 bulkhead union (item 7 in Table 2) and remove the compression nut and the
adjustable nut then place a large washer (item 8 in Table 2) against the fixed, integral body nut. Slide the
compression nut that was removed onto the bottom portion of the S-bend tube.
13. Partially insert the bulkhead union into the bottom center hole in the enclosure. Slide a large washer over the
body, and thread the adjustable nut back onto the body.
14. Insert the bottom portion of the S-bend tube into the bulkhead union and fully tighten the bulkhead union
adjustable nut against the large washer and enclosure wall. Adjust the VPS vertically in the shim/ conduit
clamp to make sure the S-bend tube is fully inserted into the union and male elbow.
15. Fully tighten the compression nuts to connect the S-bend tube to the union and to the male elbow. Tighten
the sensor conduit clamp screw to secure the sensor in its final vertical position (see Figure 11).
16. Mount the plastic enclosure onto the vapor vent stack or suitable rigid structure ABOVE the vapor vent stack
port using two conduit clamps (for 2" or 3" pipe), bolts, nuts, and washers included, or use other customer
supplied suitable mounting hardware (Example: Unistrut®). Leave the mounting hardware somewhat loose for
later enclosure height adjustment (see Figure 10).
17. Measure, fabricate, and install customer supplied pipe and pipe fittings between the vapor vent stack port
and within a few inches of the bulkhead union in the bottom of the enclosure.

18. Install one 68CA-4-4 male connector (item 5 in Table 2) onto the top of the new pipe (see View A-A,
Figure 10).
19. Measure, fabricate, and install ¼" OD copper tubing (item 10 in Table 2) between the bulkhead union and the
male connector. Adjust the enclosure vertically on vent pipe to make sure the copper tube is fully inserted into
the bulk head union and male connector.
20. Fully tighten the compression nuts to secure the fabricated tube to the bulkhead union and to the male
connector. Tighten the enclosure mounting hardware to secure the enclosure in its final vertical position.
All pitch of all vapor plumbing to drain should be 1/4" vertical per 12" horizontal to eliminate
any potential liquid traps.
21. Make sure the 3-way valve handle is set as shown in Figure 11.
22. Get the contents of the VPS drying tube kit (Table 3). Thread a tie wrap (item 3)through the slots in each of
the self-adhesive mounts (item 4). Place the top mount against the large cap on one end of the tube and
tighten the tie wrap until it is against the tube cap but you can still rotate the tube. Place the second mount
against the other end cap of the tube, again pulling the tie wrap through the mount until it is against the tube
cap but you can still rotate the tube.
23. Remove the two soft plastic seals from each end port of the drying tube. Get the Tygon tubing (item 2) from
the kit and attach one end of the tubing to one end of the drying tube. Slide the tubing onto the drying tube
as far as you can (snug). Referring to Figure 11, position the drying tube vertically in the enclosure with the
open port of the tube up, and estimate the length needed to loop from the bottom of the drying tube over to
the vent port (off center) of the VPS. Cut the Tygon tubing at the estimated length (approximately a foot or
so). Remove the paper cover from the self-adhesive base of the two tie wrap mounts and stick the drying tube
to the inside of the enclosure as shown in Figure 11. Pull each of the tie wraps snug and cut off the excess.
Attach the other end of the Tygon tubing to the vent port (off center) of the VPS.
The upper port of the drying tube must remain open and be oriented up as shown in
Figure 11.
For VPS sensor wireless installations, install the desiccant tube after installing the wireless
transmitter and battery pack components.
24. Install ½" electrical conduit from the conduit hub in the bottom of the enclosure to the customer supplied
weather-proof junction box (see Figure 10).
For Wireless installations skip Steps 24 - 27. The VPS sensor connects to a TLS RF
transmitter, not to field wiring from the TLS Console (see manual 577013-964 for
instructions).
25. Route the VPS cable into the I.S. junction box below the enclosure. Observing polarity, connect the VPS
wiring to the field wiring from the TLS console to the VPS wiring with wire nuts (see Figure 6). Seal wire nuts
in epoxy sealant following the instructions in Figure 7.
26. Push the epoxy sealed bag into the junction box. Replace and tighten the junction box cover.
27. For TLS-450PLUS console, connect VPS field wiring to a USM module (see Figure 8), For TLS-350
Consoles, connect VPS field wiring to a Smart Sensor Module (see Figure 9).
28. Close and secure the enclosure door by tightening the two T25 tamper-resistant Torx screws.
29. After the VPS sensor is installed, pressurize the tank ullage space and vapor piping to at least 2 inches WC
and test for leaks using leak detection solution.
