REQUIREMENTS
1. The pump should be located in a well-
ventilated but frost-free area.
2. The distance between pump-motor and
other objects should be at least 6 inches to
avoid overheating.
3. To minimize inlet wear, use the shortest
inlet pipe possible.
4. Ensure check valve is installed on discharge
pipe. If pump is used for boiler water supply,
a check valve must be installed in the piping
between the pump and boiler.
5. Pump should be installed on cement base,
or other similar base with suitable height. It
can also be bolted securely to a wall.
6. When installing the drainage pipe, support
pipe weight to avoid strain on the pump and
twisting of the pipe.
! WARNING !
Pump should never be mounted with the
motor hanging upside down.
7. Arrows on the inlet and outlet indicate the
direction of liquid flow through the pump.
Verify that liquid can flow easily before
starting the pump.
8. Before installation, the inlet pipeline should
be cleaned. If the pumped liquid contains
impurities, a strainer should be installed 1.5’
to 3’ in front of the inlet (particularly
recommended for pumps with flows less
than 35 gpm).
9. Avoid airlocks when installing the inlet pipe.
Refer to

10. Install bypass on outlet pipe to ensure
adequate lubrication and cooling.
11. Motor should be correctly grounded. Pump
can be damaged by phase loss, unstable
power or power surge.
12. Install a pressure meter on pump outlet to
monitor pump operation.
ELECTRICAL CONNECTION– SECTION C
! WARNING !
Electrical installation should be carried out
in accordance with the local electrical code.
Make sure that the electricity supply has
been switched off before electrical
connection.
Use care when accessing pump electrical
components.
SPECIFICATIONS
Electrical specifications (voltage, hertz) are
shown on the pump nameplate. Verify that the
power supply voltage and hertz match pump
requirements. An external ON/OFF switch must
be installed.
CONNECTION
Electrical connection should be in accordance
with diagram shown on the connecting box, and
motor current should be within rated amps as
shown on nameplate. Three phase pump
requires extra magnetic starter with protection.
ROTATION DIRECTION
On this three phase motor, rotating direction is
critical. The rotating direction is indicated on the
fan cover (counterclockwise viewing from fan
cover end). Interchanging any two leads with
power off can reverse the pump rotation.
POSITIONING CONNECTION BOX
The position of the motor connecting box is
adjustable. Referring to
Figure 4
, the position
can be changed by removing the motor fan
cover, unscrewing the frame bolts, and turning
