WARNING The compression seal (contractors plug) is not intended to replace the vapor explosion seals required by the NEC. All materials used between the power supply box and the pump junction box must be gasoline and oil resistant. Failure to comply with these, and all applicable NEC guidelines, could result in an unsafe installation. 14 a.) SINGLE PHASE UNITS: Connect the ground wire to the lug in the junction box; using the wire nuts supplied (from hardware pack p/n 400301901) connect the wires from the power supply to the orange and black wires in the junction box. Color coding is not necessary. 14 b.) THREE PHASE UNITS (except IST): Connect the ground wire to the lug in the junction box. Connect any three wires from the pump to any three wires from the three-phase power source using the wire nuts supplied (from hardware pack p/n 400301902). Install a pressure gauge in the line test port (See Figure 2), turn on the pump, and read the pressure gauge. Turn off the pump at the power supply, and change the connection of any two wires at the pump. Turn the pump back on and read the pressure gauge again. The electrical connection which gives the higher reading on the pressure gauge is the correct one. 14 c.) IST UNITS: Connect the ground wire coming from indoors to the ground lug in the junction box. Connect any three wires from the pump connector assembly to the three power wires coming from the IST- Variable Frequency Controller (indoors). Detailed installation instructions for the IST-VFC should be referenced when connecting the IST-VFC. These are supplied with the IST-VFC. � WARNING1 Not installing a ground wire increases the risk of potentially lethal electric shock and equipment failure. All holes of the compression seal (contractors plug) must be filled IV with wires or a celcon rod to enable it to seal. 15. Replace the junction box cover and tighten securely. I A� —CAUTION IThe pump discharge manifold has two labeled ports: one for the syphon system and one for the tank. A piston leak detector must be vented to the tank port (lower port) only. Do not connect a piston leak detector to the syphon port because this will make the leak detector inoperative, resulting in an increased risk of contamination of the environment (see tank port, FIG. 1). SYPHON SYSTEMS (Optional): Some jurisdictions allow two or more tanks of the same product grade to be manifolded together with a syphon loop. These systems usually have a single submersible pump, and the syphoning action keeps the tanks level while pumping out of only one tank. All FE Petro submersible pumps have syphoning capability built into the pump. However, if a syphon check valve is required, it must be requested when ordering the pumps. The outlet of the syphon check valve should be connected with a line to the highest spot in the syphon loop. When correctly installed, the syphon action between the tanks will continue whether the pump is running or not, as long as the product level in the tanks is higher than the bottom of the syphon loop vertical piping. The function of the pump in the syphon system is merely to prime the syphon line, removing the air and allowing the syphon to take place. Tanks should be of the same diameter when a syphon system is used. When this is not possible, the bottoms of the tanks should be on the same level, and the pump should be installed in the larger tank. 11
