Page 7: Fuel Pump
Adjustable Vacuum Switch Device Vaccum is the removal of pressure created by the atmosphere. This means that, in a perfect system, the absolute maximum vacuum level attainable with any device or combination of devices cannot exceed the atmospheric pressure where the system is installed. At sea level, the max level is 14.7 PSI or 29.92 in-Hg full vacuum. To protect the pump from damage, the vacuum switch is factory calibrated to a safe operating level. -
Page 8: Secondary Filter
Adjustable Pressure Switch Device To protect the pump and secondary filter from damage, the pressure switch is factory calibrated to a safe operating level. This setpoint can be recalibrated to accommodate installation configurations by following the Switch Adjustments. Adjustable Factory Setpoint: 22 PSI. •... -

Page 10: Installation
Installation It is recommended that only qualified, experienced personnel, familiar with this type of equipment, who have read and understood all the instructions in this manual should install, operate, and maintain the system. Plumbing installation must be in accordance with all applicable federal, state, and local rules, laws, standards, and regulations. Installation Diagram Key: Priming-T Check Valve... -
Page 11: Electrical
Flexible plumbing is strongly recommended for system inlet and outlet connections to the external plumbing in order to avoid issues with thermal expansion, prevent putting any stress on the internal fittings of the system, and enable ease of maintenance/installation. The pick-up line(s) should originate from the lowest point of the tank to ensure all water is removed and should be kept as short as possible. -
Page 12: Commissioning/Initial Start-Up
If the motor is running in the wrong direction and is built using 3-phase power, simply switch any 2 of the 3 hot wires provided from a 3-phase delta source. If this is not the case or switching the wires (3-phase only) does not resolve the problem, contact AXI International immediately. -
Page 13: Priming Procedure
Priming Procedure The head of the pump on the system is shipped from the factory oiled to facilitate initial lubrication. This will not eliminate the obligation to completely prime the system. The primary filter along with the suction line(s) must be completely filled with fuel (no trapped air) before initial system start-up. - Page 14 Reset the system alarm to resume operation. Slowly close the system inlet isolation ball valve while observing the system vacuum gauge reading. When the system vacuum reaches the switch calibrated setpoint, the controller will alert the condition is active. The pump will turn off after the vacuum debounce period has elapsed and the system controller will indicate high vacuum preventing the pump from operating further.

Page 18: Internal Pressure Relief Adjustment
8. Replace the rubber plug. Internal Pressure Relief Adjustment Please consult AXI International before performing any internal pressure relief adjustments to avoid warranty issues and potential damage to the system. The pump used on the STS systems comes from the factory with a pre-set internal pressure relief bypass. If the pressure on the discharge of the pump rises past this setpoint, the internal bypass will open and recirculate the fuel in the head of the pump to protect itself and any downstream components. -
