OWNER'S MANUAL
CENTRIFUGAL PUMPS
DDD/DDS SERIES
BEFORE INSTALLING PUMP, BE SURE TO READ
THIS OWNER’S MANUAL CAREFULLY.
Mechanical shaft seals do not run dry.
Fill pump with water before starting or pump will be
damaged. The motor on this pump is guaranteed by
the manufacturer and in event of failure it must be
returned to an authorized service station for repairs.
Motor warranty is void if repairs aren’t made by an
authorized repair station.
INSTALLATION
Suction Piping
The pump should be installed as close as possible to
the source of water in order to minimize the length of
suction piping. The suction pipe should never be smaller
in diameter than the suction opening of the pump. It
must be free of all leaks, and should slope continuously
upward from the water source to the pump, with no high
spots, which can trap air. A foot valve must be used to
maintain the prime.
General Piping Instructions
In order to avoid strain on the pump, both the suction
and discharge piping should be properly supported,
and a pipe wrench should be put on the suction and
discharge bosses when installing pipes in them.
Electrical Connections
Remove the end cover (canopy) from the motor, and
using the diagram on top of the motor, make sure it is
connected for the correct voltage.
