SECTION 2
INSTALLATION
2.1 GENERAL INFORMATION
The ECC is usua lly shipped already mou nted to
the pump. Installation, therefore, is usually only a
matter o f con necting the sign al wir ing ( paragraph
2.6.1) and primary power wires (paragraph 2.6.4).
2.1.1 Field Installation of ECC
Field installation of the ECC to an existing pump is
usually not recommended due to the precise align-
ment required.
MacRoy G and MacRoy D p umps cannot be con-
verted in the field to ECC operation.
MRoy A/B pumps manufactured before 1987 can-
not be converted in the field to ECC operation. The
mRoy A/B pum
p ho using must have
bee n
machined to mo unt an ECC. Co ntact the M ilton
Roy ser vice dep artment if you wi sh to conver t a
manually adjusted mRoy pump manufactured after
1987 to ECC operation.
If the ECC was supplied as a field m ounting kit,
refer to field installation instructions for the follow-
ing p umps; maxRoy B ( Appendix A) , Milroyal B
(Appendix B) o r Mi lroyal C (Ap pendix C). Upo n
completion of the retrofit, proceed with service con-
nections (paragraph 2.4).
2.1.2 ECC Circuit Board Replacement
As ECC circuit boards fail (ECC(s) built before Jan-
uary 2000) at f ield installations, they are replaced
with an ECC circuit board retrofit kit (see Table 9).
The circuit board retrofit kit replaces the old circuit
board with a new unit. Match your Milton Roy pump
to the correct circuit bo ard retrofit kit part number
using Table 9. Refer to
CIRCUIT BOARD RETRO-
FIT KIT INSTALLATION
(paragraph 2.7)
2.1.3 Circuit Board Replacement For ECC(s)
Built After January 2000 and/or After A Circuit
Board Retrofit Kit Is Replaced.
After a conversion kit is installed in the field and/or
a new ECC circuit board (ECC(s) built after Janu-
ary 2000) fails order replacement board p/n 30300
for all pu mps e xcept Milroyal C. Order p/ n 39 320
for Milroyal C pumps.
When ordering the replace-
ment board (p/n 30300/39320) specify what
pump the unit is being installed on to insure
the replacement board is configured for your
pump. This will eliminate problems during installa-
tion. Refer to Printed Circuit Board Replacement
(paragraph 4.4, Section 4
)
2.2 UNPACKING
Units are shipped f.o.b. factory and the title passes
to the customer when the carrier signs for rec eipt
of the unit. In the event that damages occur during
shipment, it is the responsibility of the customer to
notify the carrier immediately and to file a damage
claim.
Carefully examin e the ship ping cr ate/box upon
receipt from carrier to be sure there is no obvious
damage to conten ts. Open the crate/box carefully
