Parts orders must include the following information:
Pump serial number (on pump nameplate)
Model number (on ECC nameplate)
Part description
Quantity required
Always include the serial and model numbers in all
correspondence regarding the unit.
4.2 RETURNING UNITS TO THE FACTORY
Electronic Capacity Control (ECC) units will not
be accepted for repair without a Return Material
Authorization, available from the Factory Repair
Department. If the ECC is being returned attached
to a pump, process liquid should be flushed from
the pump liquid end and oil should be drained from
the pump housing before the pump is shipped.
Label the unit clearly to indicate the liquid being
pumped.
NOTE
Federal law prohibits handling of equipment that
is not accompanied by an OSHA Safety Data
Sheet (SDS). A completed SDS must be packed
in the shipping crate if the ECC is returned
attached to a pump. These safety precautions
will aid the troubleshooting and repair procedure
and preclude serious injury to repair personnel
from hazardous residue in pump liquid end.
All inquiries or parts orders should be addressed
to your local Milton Roy representative.
Representatives can be found on our website

4.3 MAINTENANCE
Because of its solid-state design, the Milton Roy
ECC is exceptionally reliable and should seldom
need maintenance or repair. Aside from calibrations
(the unit is calibrated at the factory and should
not need calibrated initially), the only typical
maintenance procedures are replacement of the
printed circuit board, feedback potentiometer, nylon
worm gear, and/or replacement of the motor.
