How To Install the A-100NV
Note:
All diagrams are strictly for guideline purposes only. Always consult an expert before installing
the A-100NV into specialized systems.
The A-100NV should be
serviced by qualified persons only.
4.1
Mounting Location
Choose an area located near the chemical supply tank, chemical injection point and electrical supply.
Although the pump is designed to withstand outdoor conditions, a cool, dry, well ventilated location is
recommended. Install the pump where it can be easily serviced.
!
Mount the pump to a secure surface or wall using the enclosed hardware. Wall mount to a solid surface
only. Mounting to drywall with anchors is not recommended.
!
Keep the outlet (discharge) tubing as short as possible. Longer tubing increases the back pressure at the
pump tube.
!
Do not mount the pump directly over your chemical container. Chemical fumes may damage the unit.
Mount the pump off to the side or at a lower level than the chemical container.
!
Mounting the pump lower than the chemical container will gravity feed the chemical into the pump. This
“flooded suction” installation can reduce the time required to prime the pump. Install a shut-off valve,
pinch clamp or other means to halt the gravity feed to the pump during servicing.
!
Your solution tank should be sturdy. Keep the tank covered to reduce fumes.
!
Be sure your installation does not constitute a cross connection with the drinking water supply. Check
your local plumbing codes.
