5.1 Discharge assembly
1. Remove the CME pump from the box and place on workbench
or work area.
If you purchased a completed CME-Plus from
the factory, a discharge pipe and union is
already installed in t he pum p dis cha rge and the
tank/transducer manifold is already assembled.
Attach the union assembly and then skip to
section 5.3 Attach the tank.
2. Wrap 3 to 4 turns of Teflon® tape on all of the male threads
of the discharge pipe f itting s.
3. Thread the 4-inch by discharge sized pipe into the discharge
of the pump. Thread the union, then the 2-inch by discharge
sized pipe and tee onto th e dis ch ar ge pipe so that tee is on its
side and the horizon tal opening f aces aw ay from the termin al
box.

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 opposite
of where the tank will be positioned. See fig. 4. Tighten until
wrench tight.

4. Thread the pressure transducer into the 1/4" NPT port of the
bushing that you ins talled in Step 3 (this is be fore wir ing the
transducer to the terminal box); see fig. 5. Tighten until wrench
tight.

5.2 Assemble the tank/transducer man ifold
1. Wrap 3 to 4 turns of Teflon tape on all of the male threads of
the pipe fittings and th e pres sure trans ducer. It is not
necessary to wra p Teflon tape on the tank threads.
2. Thread the 1/2” NPT plug into a port on the cross fitting until
hand tight. This por t ca n be any of the f our p orts of t he cr oss
fitting. See fig. 3.

5. Thread the 1/2” NPT pipe nipple in to the p ort o n the c ross
fitting opposite of t he 1/2 ” NPT plug from Step 2. Tighten
wrench tight; se e 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.

6.1 Set the pump parameters
Using an R100 rem ot e programmer, set the following para meters:
• SENSOR TYPE: A s per the la bel on the tran sduc er (t ypic ally
4-20 mA and range 0- 87 psi (0- 6 ba r) or 0-145 psi (0-10 bar))
• STOP FUNCTION:Active
• CONTROL MODE:C ontrolle d
6.2 Perform functional t est
Pump must be primed before functional test.
Start the pump and perform the following functional test including
monitoring for lea ks an d wat ching for an y ob viou s prob lems :
1. Reduce the setpoint to the s econ d LED light fro m the bo ttom
on the motor control pane l by pre ssing the D OWN a rrow as
many times as necess ary.
2. Slowly close the disc harge line valv e and o bser ve that the
motor reduces speed to compensate for the lower flow rate.
3. Fully close the disch arge lin e valv e to tes t the mo tor s top
function. (The mot or sh ould st op wit hin ap prox imat ely
2 minutes if there are no leaks ).
Note: The stop function may not operate properly, if the
setpoint 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 pump
starts again.

5.3 Attach the tank
1. Remove the plastic protective cover from over the tank
threads. Confirm the O-ring is in place and thread the tank into
the final port in the 1/2 ” NPT c ross f itting o pposit e the
pressure transd ucer. 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 press ure m ust be 0.7 x actua l se tpoin t.
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 and
Operating Instruc tions wit h th ese ad ditio nal steps:
– Wrap 3 to 4 turns of Teflon tape on the male threads of the
suction size pip e nipple .
– Thread the suctio n s ized pip e ni pple dir ect ly in the pu m p
inlet fitting.
– Thread the chec k valv e ont o the pipe nip ple; tig hten until
wrench tight.
If you purchased a complete CME-Plus from
the factory, the pressure transd u cer an d R100
settings are alread y inst alled .
2. Connect the mai n pow er cab le and pre ssu re tra nsdu ce r cable
to the motor terminal box according to the CME Installation
and Operating Inst ruc tions su pp lied with the pum p .
Warning
After setting your pump setpoint, be sure that
