3.2 START UP / OPERATIONS
A. System Checks
1. Before operating the pump tank station, verify the unit piping installation and unit
electrical installation is correct as outlined in section 2 of this manual.
2. System should be leak checked prior to pump tank system operation.
B. System Fill
1. All systems have automatic make-up. Some have mechanical and some system
useaoatswitchthatactivatesanelectricsolenoidvalve.
2. For units with electric automatic water make-up. Turn on plant water supply
to the tank and activate power supply to the tank. The water make-up solenoid
willopenandbeginllingthetank.Note: if electrical service is not connected the
tankwillnotll,manuallyllthetankuntilthewaterlevelisevenwiththelocation
of the external level switch tank.
3. For units with mechanical water make-up... turn on the plant water supply to
thetank.Thetankwilllluntilthewaterlevelreachesthemake-upoat.
4. For all units...whenthewaterlevelhasnearlyreachedthetopofthebafe,the
unit is ready to start.

4. Openasmanyprocessconnectionvalvesaspossibletoestablishawaterow
path.
D. Motor Rotation for Process Pump.
1. Activate the electrical power to the unit.
2. Turntheprocesspump‘on’momentarilyandthen‘off’again.Observetheshaftof
each motor. As the shaft slows to a stop, its rotation can be determined. Correct
rotation is clockwise when viewed from the rear of the motor.
3. If rotation for a motor is incorrect, disconnect power and reverse any two wires at
themotor’sstarterblock.
E. Motor Rotation For Tower / Evaporator Pump and Tower Fan
1. Activate the electrical power to the unit.
2. For tower system applications. It may be necessary to lower the setpoint on
the Checkmate control instrument.
3. Turnthepumporfan‘on’momentarily,then‘off’again.Observetheshaftofthe
motor. As the shaft slows to a stop, its rotation can be determined. For pump
motors, correct rotation is clockwise when viewed from the rear of the motor.
As for the cooling towers, correct rotation is counter clockwise or air should be
drawn from the bottom of the tower and out the top. For other tower cells, check
the tower cell manual for instructions on correct rotation.
4. If rotation for a motor is incorrect, disconnect power and reverse any two wires at
themotor’sstarterblock.
F. Pump Flow Adjustments
1. Whenstartingacentrifugalpump,itisimportanttoproperlysettheowrateto
prevent overloading of the pump motor. The following example is the start up
procedure for a two pump system.
2. Fully open the suction valves to the process and tower/evaporator pump. Note:
never allow the pumps to operate ‘dry’, as this can cause shaft seal failure.
3. Close the discharge valves of the process and tower/evaporator pumps. Note:
acentrifugalpumpcanbeoperatedwithnoowwithoutdamage,althoughthis
should not be for an extended period of time. Internal friction will cause the water
in the pump case to overheat.
4. Place an amp meter on one leg of the process pump wires at the motor starter.
Start the motor. Slowly open the discharge valve, allowing the process piping to
llwithwater.Afterowisestablished,continuetoopenthedischargevalve.The
ampdrawwillincreaseastheowincrease.Oncetherun-loadamprating,as
listed on the motor data tag, is reached, leave the valve in that position.

5. Note...ininitialstartup,thewaterusepointsmaynotbesufcienttofullyload
the motor. As you add use points, you should recheck the amp draw on the motor
and adjust the discharge valve as needed to prevent overloading the motor.
6. Repeat the procedure with the tower/evaporator pump.
7. On tower systems... the back pressure is very low on most tower cells. The
discharge valve may only be open one or two notches at full load.
8. Note... never operate a centrifugal pump without water in the case. Also, never
operate a centrifugal pump without checking for proper amp draw.
9. Note... always operate a centrifugal pump with the suction valve fully open.
Adjust the amp draw with the discharge valve starting from a closed position.
Starting from a wide open position can give a false reading and result in motor
overload.
10. Note... if during operations, the motor overload trips, the overloads will need to
be manually reset to restart operations. Once the pump is restarted, check for
excessive motor amps at the motor start block and throttle back the discharge
valve as needed.
G. Pump Tank Cycle
1. Two pump operation... the pump tank set is divided into two sections by a
bafe.Thesectionsarereferredtoasthe‘hotside’andthe‘coldside’.The
‘processpump’suctionisconnectedtothecoldsideandpumpswaterthrough
the distribution system. The water removes heat from the processes and returns
tothehotsideofthetank.The‘evaporatorpump’or‘towerpump’receiveswater
from the hot side of pumps the water through the chiller(s) or tower(s) and returns
the cooled water to the cold side of the tank.
2. One pump operation... the process pump suction is connected to the tank and
pumps water through the distribution system. The water removes heat from the
processes and passes through the chiller(s) or tower(s). The cooled water then
returns to the tank.
3. Standby pump operation... standby pumps are supplied as an option. If
installed on the system, they are supplied valved and wired such that switching
to back-up will take only a few minutes. A valve orientation guide is provided in
section 8 of this manual.
H. Valve Orientation for Normal and Standby Pump Operation
1. Refer to the following chart for proper position of the valves for normal and
standby operations:
I. Temperature and Pressure Gauges
1. Pressure gauges.The‘toprocess’pressuregaugesismountedonthe
dischargesideofthe‘toprocess’pumpandindicatespressuretothedistribution
system.The‘tower/evaporator’pressuregaugeismountedonthedischargeside
of the tower/evaporator pump and indicates pressure to the tower cell or chiller
evaporator.

4.2 PUMP SEAL REPLACEMENT
A. The unit pump seal is a carbon/niresist shaft
seal assembly including a stationary member,
rotatingmemberandtensionspring(gure
4.2A).
B. The operator can determine the pump seal is
leakingwhenuidisidentiedleakingfrom
the pump case adapter.
C. Generally, a pump seal will leak due to
inadequateunitpressure,excessiveowandpooruidquality.
D. The operator should follow this procedure to replace the pump seal:
1. Disengageprocessoperations.Theoperatormustbecertainprocessuid
pressureisrelieved(pressuregaugereads“0”)andwatersystemowisshutoff
and all pressure relieved.
2. Disengage main power supply. The operator must verify the Power light on the
display is off.
3. Close the suction and discharge valves.
4. Drain pump. The pump can be drained by using the drain plug located on the
pump case.
5. Locate and remove the three motor wire leads from the motor wiring terminals.
The operator should note the wire terminal locations to ensure correct rewiring.
Thepowercordshouldberemovedfromthemotorhousing(gure4.2B).
6. Locate and remove the pump casing bolts. These bolts secure the motor and
motoradaptertothepumpcasing(gure4.2C).
7. Separate the motor and motor adapter from the pump casing to expose the pump
impeller(gure4.2D).Removethemotorandmotoradapterfromtheunitand
place on a workbench to continue the procedure.
8. Locate and remove the dust cap from motor end to expose slotted motor shaft.
