To ensure your safety and comply with the terms of
the warranty, all units must be installed in
accordance with these instructions.
The pump must be installed in a location that it is
readily accessible for servicing.
An arrow is affixed to the outside of the pump scroll to
indicate the direction of rotation of the impeller.
The standard rotation of the impeller is in the
counterclockwise direction.
