<br />The tubing may be shortened.
<br />!� CAUTION: This Tins vents the air displaced by piston travel,
<br />and drains any liquid which may look past tom* piston seal.
<br />When Installing this tubing make aur* It 4 not crimped and

<br />3. Tum power on al the bad center and tum cn s 'emerged pump
<br />at a dispenser. Look for leaks at the parts )r v ked on. H there
<br />are any leaks. Immediately turn off the pc-er. g : e bad center,
<br />tag or lock out Che breaker, and repel the leaks.
<br />10. Purge remaining air from the system as Wil:- s: 'ern on power at
<br />the bad center, and dispense enough gasone `Jim the dispenser
<br />farthest from the pump to remove all the air t—, :tet line. Repeat
<br />this procedure with each disperser, working y.,.r way back to the
<br />pump.
<br />:f, on dispensing fuel In step 10 above, you and t* f.ow restricted
<br />.o 1.1,9 to 3 GPM, the look dote -dor has net opor•od. This could be
<br />due to sir trapped In the sysdem. Turn on Chs oubre-slbie pump at
<br />the dlspeneof but do not dispense any fuel. W'e't err"roxlms!*!y 2-3
<br />minutes for the punfp to pressurize the ryadern, t: -on purge the air
<br />from ail dispenoors so In stop 10 above.
<br />This look detector performs a line leak test within Lhcut 3-4 **ponds
<br />from the time the subm*m1ble pump Is turned on at the dispenser.
<br />Air or vapor In the system will cause this t-4 to be longer, In
<br />proportion to the amount of air or vapor In the line-. K the nozzle is
<br />opened before the completion of the line tee!, t"e k+k detector will
<br />detect this opening as a look and restricted flew wail result Close
<br />the nozzle for a period of tm* to allow completion of the line t**d,
<br />and the look detector will Wiow full flow again, p!v%Sded there Is no
<br />other **Cape of feet.
<br />In order to property check a line look detodor, it is necessary to
<br />have a graduated cylinder (usually g-sdue..sd in milliliters) of
<br />approxlmat*fy 30o ml volume, a testing setup cons s I hg of a piece
<br />of flexlble tubing approxime*ly 30" long with a 1:4 I.cr'T mals tittlng
<br />on on* end to a Too on the other and, to whleh a 0 to 50 Psi
<br />preeoure gouge is Installed. On the other side of :he Te* a valve Is
<br />connected to th* Too with a short nipple. A stop w-kch or a watch
<br />with a aw*+p second hand Is also required. -
<br />11. Tim If pump off at the bad center, and re:ncve ",a pipe plug in
<br />the shear -valve, beteg careful to make adeq;ate Provision to trap
<br />the squid that escapes to prevent errhnronrne!ntai contamination; and
<br />install the test fodure into the shear -valve port.
<br />Some shear -valve port are tapped 318" NPT and a reducer bushing
<br />must be used before installing the test nature.
<br />12. With the valve In the toot fbdtxe closed, urn on Ce submersible
<br />pump at the bad center and at the dispenser end look for leaks at
<br />the port of the shear -valve. K there ars a.-nyy leaks, immediately
<br />shut the pump oil at both the dispenser and at the bad center, tag
<br />or lock out the breaker, and cared the leaks.
<br />13. Turn the pump on again at both Line bad center and at the
<br />dispenser and observe the pressure gauge. 'itis pressure should
<br />increase quickly tea to 15 to 18 psi, and hesitate for 3.4 seconds Or
<br />longer ft there is air or vapor trapped in Ce system, and then
<br />Increase to approxlmatefy 21332 psi, or 40.48 psi til a High Pressure
<br />Pump. •-
<br />14. Turn the pump off at it* dispenser and open to valve 0n the test
<br />fixture, draining the fluid Into a suitable container, and observe the
<br />pressure drops to zero. Tum the submerrsble pump on again at
<br />the dispenser and direct the fluid Into a sutlabie receptacle while
<br />observing the pressure gauge, which should rot h=ase above 18
<br />psi, providing the vatye allows more than 5 gallons per hour (gph)
<br />past it.
<br />15. Gtadually close down the flow from the test fxttre until a flow rate
<br />C4 4 2 gph, which Is 265 mi68Aers per minute or 4 42 milliliters per
<br />second, is chbtafned bythe fluid Into tho graduate_ -%%-leder
<br />and recording the time, may take some Pse lee t, ;+t this
<br />exactly right. when this teak rate has been obtained, t. n tithe
<br />submersible pump off.
<br />18. After at least one minute, turn the submersible pump ba:k on at
<br />the dispenser and observe that the pressure does not gat higher
<br />than 15.18 pet. This step verities the leak detector has taxected a
<br />leak equfvalent to approximately 3 gph @ 10 psi as requi- tY the
<br />EPA. (Our lab tests have shown 4.24.4 gph @ 17 ;cu is its
<br />equivalent of 3.0 gph @ 10 psi In gasoline or rr2 S -P a at
<br />approtomalely eW F)
<br />17. Close the valve on the test fbdtre and obeerw Che ; essure
<br />Increases to 213.32 pal. Tum the subrnersble purr» oft aid drain
<br />the pressure back to zero.
<br />18. Tum the pump off at the bad center, and remove the tri i;,dhre
<br />and replace the pipe plug after apptying UL Gase'-ti'_. non -
<br />hardening. non-toxic pipe tread sealant.
<br />19. As a final check to assure Ce leak detector has been rhes e+d and
<br />is working property, before leaving Lha &Winn preform the k owing
<br />check: (It will take two people to perform this chock.)
<br />a. Turn the submersible pump on at the disperser. Dispe-ne -.,duct
<br />into a five gaiion container to assure hull flow is being
<br />obtained.
<br />b. Leaving Line dispenser switch turned on, turn the power 0t1 at the
<br />submersible pump circuit breaker (load center) and keep the
<br />nozzle open. Let stand idle for approtdmalety 1530 ser+vs.
<br />C. Turn on the power at the shbmembie pump circuit breaker.
<br />The flow out of the still open nozzle should be no more tui
<br />3 gallons per minute.
<br />d. Gose the nozzle with Line submersbte pump still running a+d
<br />wait a few w=ands or unlit you feel the pressure increase in
<br />69 line when the leak defector opens. Open the nozzle a-hd
<br />fuill flow shoed be obtained.
<br />e. Return the product Pumped to Cis storage tank.

<br />drill hole designed to socornmodate a eeefng wire, not inc4uded,
