CautionIf your pump is carrying the UL mark, official UL
approval has been given for this pump for use
with water only.
This product is Listed to applicable UL
standards and requirements by Underwriters
Laboratories Inc. for use with water only.

4. Shipment inspection
Examine the components carefully to make sure no damage hasoccurred to the pump during shipment. Care should be taken toensure the components are NOT dropped or mishandled.
Check to see that these parts are included; see fig. 8 on p. 5.

5.1 Discharge assembly
1. Remove the CME pump from the box and place on workbenchor work area.

3. Thread the 1/4” to 1/2" NPT bushing into one of the ports next
to the plug from Step 2 in the cross fitting. This will be oppositeof where the tank will be positioned. See fig. 4. Tighten until
wrench tight.

If you purchased a completed CME-Plus fromthe factory, a discharge pipe and union isalready installed in the pump discharge and thetank/transducer manifold is already assembled.
Attach the union assembly and then skip tosection 5.3 Attach the tank.

NoteThreading plug into cross fitting

2. Wrap 3 to 4 turns of Teflon® tape on all of the male threadsof the discharge pipe fittings.

4. Thread the pressure transducer into the 1/4" NPT port of thebushing that you installed in Step 3 (this is before wiring thetransducer to the terminal box); see fig. 5. Tighten until wrenchtight.

TM05 0655 1311

3. Thread the 4-inch by discharge sized pipe into the dischargeof the pump. Thread the union, then the 2-inch by discharge
sized pipe and tee onto the discharge pipe so that tee is on its
side and the horizontal opening faces away from the terminalbox.

5. Thread the 1/2” NPT pipe nipple into the port on the crossfitting opposite of the 1/2” NPT plug from Step 2. Tighten
wrench tight; see fig. 6.
6. Thread the 1/2” to discharge size NPT bushing(s) onto 1/2”
NPT pipe nipple. Tighten wrench tight; see fig. 6.

2. Discharge assembly

1. Wrap 3 to 4 turns of Teflon tape on all of the male threads ofthe pipe fittings and the pressure transducer. It is notnecessary to wrap Teflon tape on the tank threads.
2. Thread the 1/2” NPT plug into a port on the cross fitting until
hand tight. This port can be any of the four ports of the crossfitting. See fig. 3.

7. Thread the tank/transducer manifold assembly to discharge
tee as shown in fig. 7. Tighten wrench tight.

6.1 Set the pump parameters

8. Tighten the cross fitting such that the transducer, plug andbushing(s) are positioned horizontally. Tighten wrench tight.

•SENSOR TYPE: As per the label on the transducer (typically
4-20 mA and range 0-87 psi (0-6 bar) or 0-145 psi (0-10 bar))•STOP FUNCTION:Active•CONTROL MODE:Controlled

Using an R100 remote programmer, set the following parameters:

6.2 Perform functional test
NotePump must be primed before functional test.

Start the pump and perform the following functional test including
monitoring for leaks and watching for any obvious problems:
1. Reduce the setpoint to the second LED light from the bottomon the motor control panel by pressing the DOWN arrow as
many times as necessary.
2. Slowly close the discharge line valve and observe that themotor reduces speed to compensate for the lower flow rate.
3. Fully close the discharge line valve to test the motor stopfunction. (The motor should stop within approximately
2 minutes if there are no leaks).

TM05 0652 1311

Note: The stop function may not operate properly, if thesetpoint requires 90% to 100% of the motor maximum speed
or if the diaphragm tank pre-pressure is not in the desired
range.

4. Fully open the discharge line valve and observe that the pumpstarts again.
Warning
After setting your pump setpoint, be sure thatyou have not inadvertently set the pump to run on
Max Curve, Min Curve or Stop. See the CRE,CRIE...CME Installation and Operating
Instructions for more information.

5.3 Attach the tank
1. Remove the plastic protective cover from over the tankthreads. Confirm the O-ring is in place and thread the tank into
the final port in the 1/2” NPT cross fitting opposite thepressure transducer. Tank should now also be horizontal.
Tighten until hand tight.
2. The tank is pre-charged from the factory to 50 psi (+/- 7 psi)and may need to be adjusted for optimum pump performance.
Tank pre-charge pressure must be 0.7 x actual setpoint.
49 psi is the correct pre-charge setting for a 70 psi setpoint(70 x 0.7 = 49).

6. Install the pump
1. Install the pump according to the CM and CME Installation andOperating Instructions with these additional steps:– Wrap 3 to 4 turns of Teflon tape on the male threads of thesuction size pipe nipple.
– Thread the suction sized pipe nipple directly in the pumpinlet fitting.

5. The pump is ready for its normal operation now. Please see
the CME Installation and Operating Instructions supplied withthe pump for further instructions.
