THREE PHASE
FIELD ASSEMBLED INSTALLATION
1. Contractor shall furnish all labor, material, equipment and incidentals
required for installation of hazardous location pump.
2. Installation and piping instructions are included with the rail system and
basin instructions. If pump is being retrofitted to an existing rail system,
accessory parts may be required. Consult the factory and advise make
and model of rail system being used.
3. All electrical connections including pump to control box and power supply
to control panels must comply with the "National Electrical Code" and
applicable local codes. Installation of electrical panels and connections
should be made by a qualified licensed electrician.
4. When installing a pump with a check valve, or a rail system with a check
valve, you must give the pump case time to fill to help prevent air lock
when lowering the unit into the liquid. The X6404X/6405 pump case has
an air vent located behind the discharge. This air vent is across the pump
housing mounting surface and must be cleaned before each reinstall. An
air vent hole (3/16" [4 mm]) must be drilled in discharge pipe below the
check valve to help prevent air lock. This drilled hole must be cleaned
before each reinstall. After the pump is installed, run the unit submerged
to assure the pump case is filled (water should come out of 3/16"
[4 mm] diameter hole).
