Machines equipped with automatic supply
injection may also be operated manually at any time.
To operate manually, however, you must turn the chart
to the uncut position. When required, the Milnor
washer can be supplied with an electrically operated
tempering control to thermostatically control the
temperature of the water for the washer.
Milnor washers, when required, can be furnished
with a device to inject supplemental steam
automatically when called for by the formula chart and
raise the water temperature above that available from
the hot-water source. This device can also be used to
maintain minimum hot-water temperature in the
generate enough hot water to keep up with the
hot-water demand of the plant or to raise the water
washer when the normal hot-water source is unable to
tern perature near the boiling point.
The steps required to install the Milnor washer are
1. Install the washer on a steady, level floor, or
foundation. Make sure the machine is properly
bolted down to prevent vibration.
2. Assemble the water inlet valves on the rear shell
of the washer. (The water inlet valve assembly
and two water inlet valve strainers are shipped
inside of the washer.) Assembling the inlet
valves consists of plugging in a twist-lock
connection to the rear of the Miltrol timer or
plugging bullet connectors into rubber sleeves,
as shown on the inside of the Miltrol box.
On some models, the inlet valves are
control and do not require installation.
permanently attached and wired to the
3. Connect the hot and cold waterlines to the hot-
and cold-water inlet valves. (The hot-water
valve is on the left, and the cold-water valve is on
the right when you face the front of the washer.)
4 . Install one of the strainers in each of the
waterlines just ahead of the solenoid valve.
Note that some machines have water valves that
do not require strainers, so when this type of
valve is used, no strainers are shipped inside of
the washer cylinder.
Some models are furnished with a "Steam Boil"
circuit to allow any or all of the washing
operations at boiling temperature. In such cases,
connect the steam line to the steam solenoid
valve near the bottom of the washer shell at the
rear of the machine.
To eliminate water hammer when the inlet
valves close, connect the inlet valves to the
water main with a short piece of rubber hose
(about 15 to 24 inches long) between the water
main and the upstream side of the strainers. The
elasticity of the rubber hose prevents the
pounding noise that might otherwise occur
every time an inlet valve is closed.
Water inlet valves are rated to handle a
maximum of 90-psi pressure. A pressure-
reducing valve should be used to limit water
pressure when the pressure exceeds this figure.
The steam valve (when furnished) is rated to
handle a maximum of 110-psi pressure, and a
pressure-reducing valve should be used to limit
steam pressure when it exceeds this figure.
Connect the pressure supply for the automatic
drain valve to the air line or to the cold waterline.
The automatic drain valve requires a minimum
of 25-psi pressure AT ALL TIMES.
