WARNING
BEFORE BEGINNING INSTALLATION OF THIS MURPHY PRODUCT
✔ Disconnect all electrical power to the machine.
✔ Make sure the machine cannot operate during installation.
✔ Follow all safety warnings of the machine manufacturer.
✔ Read and follow all installation instructions.
The SM Series System
can monitor above or below ground,
single or multi-tank systems (4 tanks maximum). The SM Series
includes BGT1 gage (s) in a wall mounting panel. The SMVR series
includes a vapor recovery option that compensates for gas blankets or
head pressure caused by vapor recovery storage systems.
The SM includes a push-button actuated electrical pump assembly, that
supplies the air to clear sensing lines for current readings. Pump operating voltages available are 120 or 230 VAC (see below).

WARNING: Installation of the SM and SMVR Series MUST BE made by qualified installer. Hazardous conditions exist with flam-
mable and corrosive products. Extinguish all smoking materials. Risk of explosion, fire and burning can cause serious or fatal injury.
Installing a Tank Plug Kit (all models)
The tank plug kit includes 12 ft. (3.6 m) x 1/4 in.
(6 mm) dia. stainless steel tube and fittings.
Tank plug is available in 2 NPT or 4 NPT.
1.
Locate tank(s) service cover and install
a UTKN tank plug kit for each tank.
Necessary hardware is available from
Murphy, refer to “Service Parts and
Accessories” section, on page 4.
2.
Route a tubing line (1/4 in. [6 mm] outside dimension) from the tank top to the
panel location. If applicable, cut a channel in the
driveway surface to route the tubing. The use of rigid conduit is recommended especially when routing the tubing line under a driveway surface.
Refer to Fig. 1, at right.
3.
Before inserting the 1/4 in. (6 mm) dia.
stainless steel tubing (probe) through tank
plug fitting, make sure tubing can reach
bottom and also will allow extra tubing for adjustments. Now lower the
tubing until it touches the bottom
of the tank, do this as follows
(refer to Detail A, at right):
A. First, loosen ferrule and ferrule
fitting nut.
B. Insert the tubing through the
ferrule nut and fitting.
C. Mark tubing at top of fitting–raise tub-
ing exactly 3 in. (76 mm) off bottom and
finger tighten ferrule and compression nut.

D. Cut excess stainless steel tubing allowing 1/2 in. (13 mm) extension
4.
Connect tubing line to tank probe as shown
(refer to Detail B, at right).
5.
Now connect other end of tubing line
to the SM/SMVR gage panel fitting. Tubing should be continuous
length without splices.
6.
For SMVR models, connect a
second line from the tank top (if
using UTKN kit, remove Hole
Plug and install second sensor fitting and line) to the SMVR gage 1/8
NPTF fitting line. Second sensing line
is to be installed through the tank top and
into the tank, but keep the tip of the line above
product level (refer to Fig. 2, at right and Fig. 3, next page).
7.
Securely tighten all fittings; all connections must be air tight.
