Connect the drain line to the connection in the
BOTTOM of the automatic drain valve. The
threaded connection in the side of the automatic
drain valve is a cleanout hole only.
The Miltrol timer is equipped with a step-down
transformer to lower the voltage at the contact
fingers to 24 volts. Some electrical components
in the timer operate on 24 volts (the lamps, timer
relays, water valves, etc.). Provide a line
disconnect switch for each washer, so any
washer in your installation can be turned off for
repairs without affecting the operation of the
Adjust the level control for the desired high- and
low-water levels. The level control is set at the
factory to deliver the approximate water depths.
However, the final adjustment must be made in
Connect the supply injector unit to a source of
water for flushing. Use one size larger if the
pipe run is more than 5 feet. When the water
piping for the supply injector is too small, the
supply injector does hot flush the supplies
properly. When available, hot water should be
used for flushing but only if your hot-water
source is dependable, has at least 20-psi
pressure, and does not occasionally boil over
and produce steam in the hot waterline. If hot
water is not available, use cold water.
Five solenoid valves are within the supply
injector. These valves can handle a maximum
of 30 psi. They are adequately protected against
higher pressure by the pressure-reducing valve
that has been properly set at the factory to
deliver between 25 to 28 psi. Be sure to check
the pressure gauge and reset it to 25 to 28
pounds, as vibration and/or handling in
shipment may cause the regulator to get out of
Maintenance and Repair
The Milnor washer should be inspected at regular
intervals to ensure that it works properly. If an
inspection reveals adjustments or repairs are needed,
they should be made promptly.
Some models are equipped with electric
drain valves that do not require air or
water pressure connections.
The inspection of a washer should ensure that
proper conditions exist. These conditions include the
The machine is level.
All bolts, nuts, and screws are tight.
Latches on cylinder doors work properly.
The thermometers are accurate.
Switches are properly adjusted and working
Timers are in good working order.
Water level gauges are correct.
All electric controls are working.
you should make special inspections as follows:
In addition to the regular scheduled inspections,
EVERY 2 MONTHS:
Check the gearbox oil level and replenish with
fresh oi I, if necessary.
Lubricate the clutch drag spring with two or
three drops of light machine oil between the
left-hand chassis end frame and the chart drag
spring holder, a shown by arrow (1) in figure
Drain the gearbox and replenish it with fresh oil.
The drain plug in the bottom of the gearbox has a
small magnet in its end to attract metallic
particles in the oil. Be sure to clean off the
magnet each time the gearbox is drained and
before reinserting the drain plug.
Clean the motor clutch assembly, as shown by
arrow 2 in figure 5-11, with one or two squirts of
Navy-approved nonflammable cleaning fluid.
Wipe the fluid off with a clean, dry rag and
lubricate with two or three drops of light
machine oil to prevent the clutch spring from
"gumming up" and allowing the clutch to slip.
Wipe off excess lubricant.
The washer is a rugged machine, but from time to
time you can expect trouble. A troubleshooting chart
for the Milnor washer is contained in table X of
appendix II of this TRAMAN.
