Installation Safety Procedures
•
Any system throttling valves or similar devices controlling flow rate must be installed in discharge line.
Do not
install
devices in supply line. Restriction in supply line may cause cavitation and pump damage.
•
"Water hammer" in system can damage pump and other system components. Water hammer often occurs when
valves in system are suddenly closed causing lines to move violently and with a loud noise. When this condition is
present, find and eliminate source of water hammer. One way to eliminate water hammer is to slow down actuation
speed of valve.
•
Do not expose pump to freezing temperatures with liquid in casing. Frozen liquid in casing will damage pump. Drain
casing before exposing to freezing temperatures.
Pump Leveling
Level pump by loosening set screws (Figure 5, item A) to
adjust length of legs.
Type 4 Seal Flush Supply Installation
Attach seal flush supply to bottom 1/4-inch pipe-threaded
hole in flush housing. Drain tubing attached to top hole
allowing continuous flooding and moderate pressure to be
supplied to seals. (Figure 6).
Electrical Connections
WARNING:
To avoid electrocution, all electrical
installation should be done by a registered
electrician following Industry Safety Standards. All
power must be off and locked out during
installation.
•
Read motor manufacturer's instructions before
making installation. Follow manufacturer's
lubrication schedules.
•
Check motor nameplate to confirm motor is
compatible with all wiring, switches, starters and
electrical supply. Ensure overload protections are
correctly sized. (Figure 7).
