Page 11: Primary Inspection
Primary Inspection Upon arrival, the system and accessories must be visually inspected before installation. Improper handling during shipping may cause physical or electrical problems. Immediately report or note any damages to the shipper. Checklist If the packing crate shows signs of damage inspect the system for damage. Check the entire system for damage that could indicate internal mechanical or electrical problems. -
Page 12: Installation
If the motor is running in the wrong direction, contact AXI International immediately. !WARNING!: The whole system (enclosure, plumbing, motor, electric sub panel) must be properly grounded for operator safety. -
Page 13: Typical Plumbing Installation (Schematically)
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). 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. - Page 14 Ensure all external electrical connections are linked to their corresponding ball valve as indicated by labels on the sides of the system’s enclosure. The provided external High Tank Fuel Level Alarm Inputs (see provided electrical drawings) must be wired to the Normally Closed High Level Alarm Contacts on each tank to avoid overfilling and potential spills.
