Installation 4
SERIES C/CC CENTRIFUgAL PUmPS
The “C” and “CC” Series pumps are close coupled pumps with optional
traps. “CC” Series have cast iron volutes and adapters. “C” Series have
bronze volutes and adapters. Impellers on both series are bronze.
INSTALLATION
Location of Unit
Install pump as close to liquid source as possible, using short, simple
suction piping.
Piping should be as direct as possible; elbows and other fittings greatly
increase friction losses.
Allow service and maintenance access.
Mount on solid, rigid, vibration-free foundation.
Protect pump against flooding and excess moisture.
Piping
Pump is not self-priming. Unless liquid source level is above pump
suction at all times, install a foot valve on suction pipe.
Support both suction and discharge piping independently near the pump
to avoid placing strains on pump. Start all piping at pump to avoid strains
left by a gap at last connection.
If possible, increase size of both suction and discharge piping if more
than short runs are required.
NOTICE: Never use a suction pipe smaller than the suction connection of
the pump.
NOTICE: If a reducer is necessary in the suction piping, always use an
eccentric reducer with the straight side on top.
NOTICE: BE SURE suction does not leak. Suction pipe must slope
gradually upward to the pump. Avoid any fittings which might cause an air
trap.
Install gate valve and union in suction and discharge lines. If complete
pump removal is required for service, close gate valves and disconnect at
unions.
Grounding the Motor
Hazardous
voltage
Can shock, burn or cause death.
Ground motor before working
on pump or motor.
Install, ground, wire and maintain this pump in accordance with the
National Electrical Code, Article 250, or applicable local Codes and
Ordinances.
Ground the pump permanently using a wire of size and type specified
by National or Local Electrical Code.
Connect ground wire first. Connect to ground first, then to motor
terminal provide. Do not connect motor to electrical power supply until
unit is permanently grounded. Any other sequence may cause serious
shock hazard. Do not ground to a gas supply line.
The motor grounding wire need not be larger than the wires supplying the
motor, provided the supply wires conform to the wiring date included in
this manual (see Table I, Page 5).

Installation / Maintenance 5
Wiring
NOTICE: For 575 volt installations, see motor nameplate. Consult a
licensed electrician for wiring information. Installation must meet code.
For 200, 230, and 460 volt installations, check fusing/wiring data chart
(Table I, below) before connecting pump to power source.
Check that voltage/frequency on motor nameplate are identical with
voltage/frequency of incoming power supply.
NOTICE: Wire dual voltage motors correctly according to wiring diagram
on motor.
Check rotation of motor. Look through opening in adapter. Rotation
should be clockwise when viewed from the motor end. If not:
• TurnpumpOFFanddisconnectfrompowersource.
• Forthree-phasemotors,reverseanytwoleadstomotorstarter.
• Forsinglephasemotors,re-connectaccordingtowiringdiagramon
motor.
Priming the Pump
NOTICE: NEVER run pump dry. To run pump dry may damage seals.
To Prime:
1. If pump is installed below liquid source level, open gate valve in
suction line and flood suction.
2. If pump is not installed below liquid source level, fill pump through a
tee installed in pump discharge and fitted with a priming plug in the
upright position.
Tighten priming plug securely after priming!
IMPORTANT: BE SURE lead wire opening on end of
motor is fully sealed when conduit or a pressure switch
is not used. Failure to seal it properly will allow dirt, rain,
bugs, etc. to enter back compartment of motor through
conduit opening and cause switch malfunction.
