9. 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.

10. 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 others.

11. 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 the field.

12. 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.

13. 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 adjustment.

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.

NOTE

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 following:

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 correctly.

Timers are in good working order.

Water level gauges are correct.

All electric controls are working.

In addition to the regular scheduled inspections,

you should make special inspections as follows:

EVERY 2 MONTHS:

Check the gearbox oil level and replenish with fresh oi I, if necessary.

SEMIANNUALLY:

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 5-11.

ANNUALLY:

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.

Troubleshooting

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.
