INSTALLATION

PIPING - GENERAL
Support both suction and discharge piping independently at a
point near the pump to avoid putting a strain on the pump housing.
Start all piping AT THE PUMP.
Increase pipe diameter at both the suction and discharge by one
(1) standard pipe size (minimum) to obtain desired performance
and flow rate. Refer to Table I when sizing pipe for your pumping
system.
NOTICE: Do not use pipe with smaller diameter on the suction
side of pump.

SUCTION PIPE
Increase pipe size from pump tapping as shown in Table I shown
above. Figure 1 (Page 4) depicts a recommended run of pipe and
fittings for the suction side of a centrifugal pump. Please refer to
this illustration when choosing pipe and fittings for your suction
connection.
IMPORTANT: All connections must be air tight! Figure 2 (Page
4) depicts conditions that are NOT DESIRABLE on the suction
side of a centrifugal pump and may cause problems in flow rate
and priming. Please look this illustration over carefully before
choosing pipe and fittings for your suction connection.

DISCHARGE PIPING
Increase pipe size from pump tapping as show in Table I. Figure
1 (Page 4) depicts a recommended run of pipe and fittings for
the discharge. Install tee with priming plug as close to pump
as possible. Figure 2 (Page 4) notes conditions that should be
avoided. Please read over carefully before making discharge
connection.
PRIMING THE PUMP
A pump is primed when all air in the suction line and pump volute
has been evacuated and replaced with water.
To Prime:
1. Close valve in discharge line.
2. Remove priming plug from tee and fill pump and suction line
with water until water is flowing back out of tee.
3. Replace priming plug.
4. Start pump and slowly open valve until desired water flow
is achieved.
NOTICE: If water is not being pumped, turn off pump, close valve,
and repeat steps 1 through 4.
If pump volute is rotated as shown in Figure 1 (Page 4), loosen
vent plug when priming to evacuate air trapped inside volute
and tighten when volute is completely filled with water.
Risk of explosion and scalding. Never run pump
against closed discharge. To do so can boil water inside pump,
causing hazardous pressure buildup and possible explosion.
Risk of flooding. Do not run the pump dry. This will
damage mechanical seal and void warranty. It may cause burns
to person handling pump.
Motor normally operates at high temperature and
will be too hot to touch. It is protected from heat damage during
operation by an automatic internal cutoff switch. Before handling
pump or motor, stop motor and allow it to cool for 20 minutes.
