SAFETY INSTRUCTIONS
TO AVOID SERIOUS OR FATAL PERSONAL INJURY
OR MAJOR PROPERTY DAMAGE, READ AND
FOLLOW ALL SAFETY INSTRUCTIONS IN MANUAL
AND ON PUMP.
THIS MANUAL IS INTENDED TO ASSIST IN THE
INSTALLATION AND OPERATION OF THIS UNIT
AND MUST BE KEPT WITH THE PUMP.
This is a SAFETY ALERT SYMBOL.
When you see this symbol on the pump
or in the manual, look for one of the fol-
lowing signal words and be alert to the
potential for personal injury or property
damage.
Warns of hazards that WILL cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause per-
sonal injury or property damage.
NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS
AND WARNINGS PRIOR TO PERFORMING ANY
WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
UNIT NOT DESIGNED FOR USE
WITH HAZARDOUS LIQUIDS
OR FLAMMABLE GASES. THESE
FLUIDS MAY BE PRESENT IN
CONTAINMENT AREAS.
NOTICE: INSPECT UNIT FOR DAMAGE AND
REPORT ALL DAMAGE TO THE CARRIER
OR DEALER IMMEDIATELY.
1. Important Instructions
1. Inspect unit for damage. Report damage to carrier
immediately.
2. Electrical supply must be a separate branch circuit
with fuses or circuit breakers, wire sizes, etc., per
National and Local electrical codes. Install an all-leg
disconnect switch near pump.
ALWAYS DISCONNECT
ELECTRICAL POWER WHEN
HANDLING PUMP OR CONTROLS.
DANGER
WARNING
CAUTION
WARNING
Hazardous fluids
can cause fire,
burns or death.
3. Motors must be wired for proper voltage (check
nameplate). Wire size must limit maximum voltage
drop to 10% of nameplate voltage at motor terminals,
or motor life and pump performance will be lowered.
4. Single-Phase: Thermal protection for single-phase units
is sometimes built-in (Check nameplate). If no built-in
protection is provided, use a contactor with proper
overload. Fusing is permissible if properly fused.
5. Three-Phase: Provide three-leg protection with proper
size magnetic starter and thermal overloads.
6. Maximum Liquid Temperatures:
212ºF (100ºC) with standard seal.
250ºF (120ºC) with optional high-temperature seal.
7. Maximum allowable operating pressure: 230 PSI
(15 bars).
8. Maximum number of starts per hour: 20, evenly
distributed.
9. Regular Inspection and Maintenance will increase
service life. Base schedule on operating time.
2. Installation
1. Close-coupled units may be installed inclined or vertical.
DO NOT INSTALL WITH MOTOR
BELOW PUMP. CONDENSATION
WILL BUILD UP IN MOTOR.
2. Locate pump as near liquid source as possible (below
level of liquid for automatic operation).
3. Protect from freezing or floods.
4. Allow adequate space for servicing and ventilation.
5. For close-coupled pumps, the foundation must be flat
and substantial to eliminate strain when tightening
bolts. Use rubber mounts to minimize noise and
vibration. Tighten motor hold-down bolts before
connecting piping to pump.
6. For frame-mounted pumps, permanent and solid
foundation is required for smooth operation. Bedplate
must be grouted to a foundation with solid footing.
7. Place unit in position on wedges located at four points
(Two below approximate center of driver and two
below approximate center of pump). Adjust wedges to
level unit, bringing coupling halves into reasonable
alignment. Level or plumb suction and discharge
flanges.
8. Make sure bedplate is not distorted and final coupling
alignment can be made within the limits of movement
of motor and by shimming if necessary.
9. Tighten foundation bolts finger tight and build dam
around foundation. Pour grout under bedplate making
sure the areas under pump and motor feet are filled
solid. Allow grout to harden 48 hours before further
tightening foundation bolts.
10. All piping must be supported independently of the
pump, and must “line-up” naturally. Never draw
piping into place by forcing the pump suction and
discharge connections!
11. Angular alignment of the flanges can best be accom-
plished using calipers at bolt locations (See illustra-
tion).
WARNING
Hazardous voltage
can shock, burn or
cause death.
