About the Manual Identifying Information on the Cover
The front cover displays pertinent identifying information for this manual. Most important, are
the published manual number (part number) /ECN (date code). Generally, when a replacement
manual is furnished, it will have the same published manual number, but the latest available
ECN. This provides the user with the latest information applicable to his machine. Similarly all
documents comprising the manual will be the latest available as of the date the manual was
printed, even though older ECN dates for those documents may be listed in the table of
contents.
When communicating with the Milnor factory regarding this manual, please also provide the
other identifying information shown on the cover, including the publishing system, access date,
and whether the document ECN’s are the latest available or exact.

hardware/software (hereafter referred to as “equipment”), will be free from defects in material
and workmanship for a period of one year from the date of shipment from our factory with no
operating hour limitation. This warranty is contingent upon the equipment being installed,
operated and serviced as specified in the operating manual supplied with the equipment, and
operated under normal conditions by competent operators.
Providing we receive written notification of a warranted defect within 30 days of its discovery,
we will – at our option – repair or replace the defective part or parts, FOB our factory. We

brake and clutch linings and similar parts – are not covered by this warranty, nor are parts
damaged by exposure to weather or to chemicals.
We reserve the right to make changes in the design and/or construction of our equipment
(including purchased components) without obligation to change any equipment previously
supplied.

1. Model and serial number of the machine for which the parts are required
2. Part number
3. Name of the part
4. Quantity needed
5. Method of shipment desired
6. In correspondence regarding motors or electrical controls, please include all
nameplate data, including wiring diagram number and the make or
manufacturer of the motor or controls.
All parts will be shipped C.O.D. transportation charges collect only.
Please read this manual

ÈFUSE/CIRCUIT BREAKER AND WIRE SIZING
•Grounding
•Fuse Sizing
•Circuit Breaker Sizing
•Wire Sizing
ÊGrounding
Ground machine to an earth ground (zero potential). Use a ground wire of at least as large a gauge as that
required for incoming power; do not rely on conduit, machine anchorage, etc. Connect the ground wire between the
ground lug on the incoming power junction box on the machine and the external disconnect box or other location
as required to assure a reliable earth ground.
ÊFuse Sizing
Size external fuses per the external fuse and wire size table in the schematic manual. The recommended fuse
sizes are per National Electric Code (NEC) section 430-52, exception No. 2 Part B, as follows:
The rating of a time-delay (dual-element) fuse shall be permitted to be increased, but shall in no case exceed
225 percent of the full-load current.
UNSAFE OPERATION AND MACHINE DAMAGE HAZARDS—Correct fuse must be used. An
extract motor may take up to two minutes to accelerate the basket to full speed, during
which time the motor draws nearly locked rotor current. All motors on dryers and mem-
brane presses may run at the same time requiring fusing for the whole group.
☞NEVER use fuses other than those specified in the tables in the schematic manual.
☞Use only Bussmann Fusetron FRN (up to 250V), FRS (250 to 600V) or similar lag type
fuses.
ÊCircuit Breaker Sizing
If an inverse time circuit breaker is to be used, it should have the same characteristics as FRN/FRS type fuse,
which will allow you to use the Fuse Size as shown in the table; otherwise, use the Circuit Breaker Size shown in
the table. The calculation is per National Electric Code (NEC) section 430-52, exception No. 2 Part C, as follows:
The rating of an inverse time circuit breaker shall be permitted to be increased but shall in no case exceed
400 percent for full-load currents of 100 amperes or less.

ÊWire Sizing
Size wire as follows:
1. Except as noted in item 2, below, size wire per the external fuse and wire size table in the schematic manual,
for runs up to 50 feet (15 meters). Use next larger size for runs 50 to 100 feet (15 to 30 meters). Use wire
two sizes larger for runs greater than 100 feet (30 meters).
2. If an inverse circuit breaker is to be used and local code requires a larger wire size than called for by the exter-
nal fuse and wire size table, abide by the local code.
UNSAFE OPERATION AND MACHINE DAMAGE HAZARDS—Correct wire size must be
used. Smaller wire—even though its current-carrying capacity may be greater than the re-
quired fuse—may cause voltage drops, thereby reducing starting torque. (A 5% voltage
drop causes motor to produce only 90% of its rated torque.) The voltage drop is greatest
the instant the motor is energized, thus when highest torque is required.
☞Never use wire of a smaller size than called for by the external fuse and wire size table
in the schematic manual.
Wire size shown in the
external fuse and wire size table
may sometimes appear to be too
small for the fuse/circuit breaker shown. However, the listed wire size is acceptable for the
load imposed by the machine and commensurate with the National Electric Code.
