Installation
Note: 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.
Mounting
The unit should be permanently wall mounted on a hard, level surface. Use provided mounting holes located on the back
plate for proper fastening (Refer to mechanical drawing(s) for Mounting Hole Diameter). Ensure the system is level and
secure, enabling water to be more accurately sensed in the primary filter’s sump. Be sure to secure the system in a
location that allows all piping and electrical wiring to be safely routed to the system. This unit is designed for well-
ventilated indoor use within the specified temperature range and should be located as close to the tank as possible.
Electrical
!WARNING! To avoid the risk of electric shock, make sure that the power supply to the system is disconnected
and ensure that the system is at zero volts, before working on any of the system’s electrical parts.
Make sure that the system’s power requirements and rated voltage/frequency match your electrical system (see wiring
diagram). The system may only be connected to properly grounded power sources for operator safety. Connect all
components to the ground studs provided as shown on the provided drawings. The system connects to either 12VDC or
24VDC with the positive lead from your power source to the red wire and the negative lead to the gray wire. After the
initial wiring of the system check operation to ensure that it is running in the correct direction. If the motor is running in the
wrong direction, contact AXI International immediately.
!WARNING! The whole system (enclosure, doors, plumbing, motor, electric sub panel) must be properly
grounded for operator safety.
Depending on length of run, use wiring according to specification in wiring diagram and connect system to a separate UL
listed breaker (not included) appropriate for branch circuit protection. Connect the System Controller to the filtration unit
with the provided plugs and wiring harnesses.
Note: Wiring and electrical installation must be in accordance with all applicable federal, state, and local rules, laws,
standards, and regulations.
Plumbing
Note: Please ensure to check all of the plumbing (joints, unions, miscellaneous fittings) for tightness prior to completion.
Use proper quality approved fuel line materials with similar inner diameter (ID) to the inlet/outlet of the system. For
extended suction side plumbing runs, it is recommended to install oversized pipe, (1/4” to 1/2” increased ID) (Ref.: Page 4
– Suction Capability).
It is imperative that external, manual inlet and outlet ball valves be installed on each side of
the filtration system. That will enable it to be isolated from the external piping apparatus, eliminating the
possibility of the system to be damaged by over-pressurization of said plumbing during initial start-up testing
(IST).
Note: Flexible plumbing is strongly recommended for system inlet and outlet connections to 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. Install manual inlet and outlet ball valves prior inlet flexible plumbing and post outlet flexible
plumbing respectively.
The pick-up tube/line(s) should originate from the lowest point of the tank to ensure all water is removed. Also, it should
be connected directly to the system’s inlet port (located on the left-hand side of the system) and be kept as short as
possible. It is recommended that an oversized, low restriction foot valve be installed to keep the system primed, especially
