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.

ÈSERVICE CONNECTIONS FOR GAS, STEAM, AND
HOT OIL DRYERS, CONDITIONERS, AND SHAKERS
ÊGeneral
The service connections which may be required depending upon machine model and optional features are as
follows:
1. Piped Inlets and Outlets: cold water, compressed air, gas, steam, hot oil, steam condensate or hot oil return
line or gas line vent, main air intake, main air exhaust. The sizes and locations of piped inlets and outlets are
shown on the dimensional drawing for your machine.
2. Electric Power Connections.
3. Electrical Control Connections.
ÊPrecautions for Piped Connections
1. Inlet pressure must be within the minimum/maximum range specified. Pressure outside of the specified range
may cause the machine to operate inefficiently or to malfunction and may damage machine components.
Do not distort valve bodies when connecting plumbing. Hold tension
against these valves with a wrench on the side of the valve onto which the
pipe is being connected; otherwise, the valve will be twisted and distorted.
2. When connecting water and steam inlets, always install unions and shut off valves at the point of connection
to permit removal of the machine components for servicing, if necessary.

ÊPrecautions for Electrical Connections
SHOCK HAZARD—Electrical source can cause death or severe injury. Connec-
tions must be made by a competent electrician.
1. Prior to making power connections, read the instructions on all related tags.
2. “Stinger leg” if any, must only be connected to terminal L3, never to terminals L1 or L2.
3. See fuse and wire sizing information in schematic manual and on machine nameplate.
4. Verify all motor rotation. If the cylinder turns in the wrong direction, interchange the wires connected to L1
and L2. Never move L3.
ÊElectric Power Connections
The customer must furnish a remotely mounted disconnect switch with lag type fuses, circuit breakers, and
wiring between this box and the fuse box on the machine. The sizes of these fuses and wires, along with the motor
fuses supplied with your machine, depend on the machine voltage.
FIRE HAZARD—Do not operate this machine unless sprinkler is functional and
is connected to an adequate water source, as described in table of Piped Inlets.

ÈHOW TO SIZE INLET AND
DISCHARGE AIR DUCTING
ÊIntroduction
Proper airflow is a critical factor in maintaining optimum performance. The inlet and exhaust air ducts must
be correctly designed to prevent excessive pressure drop which will starve the machine of air, causing longer drying
cycles and possibly poor combustion in gas heated dryers.
It is highly recommended to always connect the air inlet to a source of outside air; other-
wise, the machine will be starved of air, unless large windows and doors ARE ALWAYS
OPEN—a climatic impossibility in most installations.
Provided the pressure drop is uniform throughout the entire drying cycle, your MILNOR machine will
provide a proper air flow against a maximum total pressure drop of .5" (13mm) water column. This value
must be measured between where the inlet and outlet air ducts connect to the machine and thus includes all suction
and discharge pressure drops caused by the inlet and outlet duct work, plus any external lint filter, roof-top wind
loads, etc.
Most external lint collectors with cloth filters have proven to be inadequate because fine
meshcloth filters tend to block rapidly duringa drying cycle, while coarse mesh clothfilters
tend to pass unacceptable quantities of lint.
Choose the correct duct size and routing to keep the total pressure drop below the recommended maximum
pressure. Note that round ducting is best because it minimizes pressure drop and tends to reduce lint build-up in the
duct. However, data for both round and rectangular ducts is given in a table in this section.
ÊPrecautions for Fabricating Ducting
1. The blower is adequately sized to overcome the pressure drop mentioned above, providing the pressure
drop is relatively constant. Moreover, different positions of the automatic airflow dampers in the dryer can
be selected to cope with different inherent but steady-state pressure drops in the duct. However, a variable
pressure drop (possibly caused by a lint filter that becomes progressively loaded or blocked during the
drying cycle) will significantly reduce productivity because of the following:
a. If the dampers are selected for a suitable airflow at the beginning of the drying cycle, when the lint filter is
newly stripped and relatively free, the airflow (and productivity) will be drastically reduced toward the
end of the drying cycle as the filter becomes loaded with lint.
b.If the dampers are selected for a suitable airflow at the end of the drying cycle, after the pressure drop has
increased because of the lint on the filter, the airflow at the beginning of the drying cycle will be so
great that the goods will tend to plaster themselves against the perforations inside the cylinder. This will
also effectively reduce the actual airflow through the goods and thus drastically reduce productivity.
2. Do not employ “turning vanes” in any external ducts connected to your machine. Turning vanes may
quickly clog with lint. Lint build-up in the ducts will reduce the airflow and the dryer’s performance, and
also cause a fire hazard!
3. Do not employ right angle elbows. Use only elbows with radii no smaller than that shown in FIGURE 1.
4. Adequately sized inspection covers should be placed near every elbow for the periodic removal of lint.
5. All transitions should be smooth. Transitions may be considered as straight duct if the taper is less than 7 1/2o.
6. Because the resultant varying pressure drop will prevent the machine from performing correctly, never con-
nect two or more machines to a common exhaust duct.
7. Two or more machines may be connected to a common powered wet or dry type lint collector, providing:
a. Separate ducts must be run from each machine to the collector, and,
b. The lint collector’s fan capacity must be capable of accommodating the maximum combined flow from all
machines connected to it. The lint collector must have a variable speed motor or other equivalent means
responsive to the number of dryers actually running to maintain a constant back pressure not greater
than .5" (13) water column, nor less than zero.
8. This information is intended to be general in nature and is provided only as a guide. MILNOR accepts no
responsibility nor liability resulting from the use of this information. You may find it advisable to employ
the services of a professional engineer licensed to practice in your area.
