Parts orders must include the following information:
1. Quantity required.
2. Part number.
3. Part description.
4. Pump serial number.
5. PCC model number.
Always include the serial and model numbers in all
correspondence regarding the unit.
4.2 RETURNING UNITS TO THE FACTORY
PCC units will not be accepted for repair without a
Return Material Authorization, available from the
Factory Repair Department. If the PCC is being
returned attached to a Milroyal
®
B 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 PCC 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 or sent to:
www.miltonroy.com.
4.3 REMOVAL OF CONTROL UNIT
Before removing the Control from the pump, it is
necessary to position the control at 100% capacity
by applying proper instrument air signal (usually
15 psi (103 kPa)). Then:
1. Shut OFF supply air pressure and disconnect
line at the control.
2. Shut OFF instrument air pressure and disconnect
line at the control.
3. Remove the oil drain plug (1460)
(see drawing
on page 12)
from the bottom of the reservoir
and collect oil in a shallow pan.
4. Remove Control mounting screws (1350)
and pull Control away from mounting collar
(1330) until adapter shafts (1100 & 1320) are
exposed.
5. Unbend locking tabs on lock ring (1310) located
against flat actuating shaft (1100).
