14.2 Swivel Couplings Connections Swivel couplings require the use of a small swivel wrench for tightening the coupling swivel nut. The following connection procedures need to be followed for proper installation. NOTE: If standard test boots are to be used, be sure to slide the boots onto the pipe prior to connecting to the fitting. 14.2.1 Coupling Inspection Remove the protective cap from the swivel pipe coupling and verify that the flat ring gasket is seated in the back of the swivel nut and free of dirt and debris. If test boots are to be installed, make sure that they have been properly installed, as described in section 15.2 Installing Test Boots. 14.2.2 Fitting Inspection Remove the plastic protective cap from the metallic fitting or adapter. Inspect the metallic fitting or adapter to be sure that it is free of sand or debris and there is no damage to the sealing face. 14.1.3 Hand i igntening oT 5wivei Nut When installing swivel couplings, hand tighten the coupling onto the OPW-FCS fittings until it is snug. With an OPW- FCS swivel wrench, tighten the coupling nut '% turn more or to 200 in/lbs. Do not allow the pipe to rotate while tightening. The % turn procedure will prevent over tightening of the coupling past the maximum 200 in/lbs. NOTE: Failure to follow this procedure may result in damage to the coupling gasket. 15.0 TEST BOOTS Test boots are installed only onto double wall piping that is coupled and fitted with either swivel couplings & fittings. These rubber boots must be installed onto the end of double wall pipe section prior to connecting the piping section to the fitting. Standard test boots are used with swivel couplings. 15.1 Test Boot Applications Test Boots must be installed, for double wall piping applications, having swivel couplings & fittings installed and require a means for air pressure testing or continuous monitoring of the pipe's interstitial space. 5.1.1 Tank Sumps Test boots installed in these sumps should be connected to the 36" (914mm) long test tubes. The fitting on the end will accept the test gauge used for air pressure testing. 15.1.2 Junction Dispenser Sumps 15 F1:_. W0R KS BY OPW FUELING CONTAINMENT SYSTEMS Test boots installed in these sumps should be inter- connected with the approximate size connector tubes. 15.1.3 Terminating Dispenser Sumps Test boots installed in these sumps should be connected to the 36" (914mm) long test tubes and plugged on the end when conducting the air pressure test. 15.1.4 In-line Piping Sump Connections Test boots installed in these sumps should be interconnected with a custom length connector tube. 15.2 Installing Test Boots After all pipe sections have been inserted into the containment sumps and before any piping connections are made, the rubber test boots must be installed first. The test boot has an outlet opening located on the bottom for connection to either test tubes or connector tube as described in section 16 Tubing Assemblies of this product manual. Comply with the following three step installation procedures for proper installation of the test boots. Standard Test Boots (Swivel) Position the Test Boot with the outlet port facing down. Align the boot so that one clamp is over the green secondaryjacket and the other clamp is over the metal ferrule of the pipe coupling. Next tighten down band clamps to 30 in/lbs. 15.2.1 Removing Band Clamps Remove both band clamps from the test boot before installing the rubber boot over the end of the coupled flexible pipe section. 15.2.2 Installing Test Boot From inside the containment sump, slide the test boot over the installed pipe section end of the pipe section. 16.0 TUBING ASSEMBLIES OPW-FCS flexible piping systems incorporates the use of plastic tubing for purposes of providing convenient access to, and interconnecting of the interstitial space of the double wall flexible piping line. Double wall piping having either swivel or barbed piping connections and installed with test boots can be fitted with both test tubes and connector tubes. Double wall piping having coax piping connections can be fitted using only coax test tubes. 16.1 Test Tubes There are two types of test tubes available for use with double wall piping: one for connection to coaxial fittings & adapters and the other for connection to test boots installed with swivel piping connections. These 36" (914mm) long
