Laundry Facility

Provide a supporting floor that is strong and rigid enough to support—with a reasonable safety
factor and without undue or objectionable deflection—the weight of the fully loaded machine and
the forces transmitted by it during operation. Provide sufficient clearance for machine movement.

The laundry facility must provide protection from the elements. Do not install the machine

where it will be exposed to the weather.

As of this writing, the National Electrical Code requires a clearly marked electric disconnect
switch within sight of the machine and no farther away from the machine than 50 feet. Local
codes may have additional requirements.

You are urged to consult your licensed electrician and take immediate steps to comply if your
installation does not meet the National Electrical Code requirement and/or local codes.

Under certain conditions, hydrogen gas may be produced in a hot water system that has not been
used for 2 weeks or more. Hydrogen gas is explosive. if the hot water system has not been used
for such a period, before using a washing machine, turn on all hot water faucets and let the water
flow from each for several minutes. This will release any accumulated hydrogen gas. As the gas
is flammable, do not smoke or use an open flame during this time.

Preface

Laundry owners, managers and employees must familiarize themselves with these hazards and
actively prevent any condition in their facility which might make accidents from these hazards
more likely. These hazards are described in more detail below.

PELLERIN MILNOR CORPORATION

Preface

iii. 1.

The Danger of Child Entrapment and Scalding

There have been child entrapment incidents with machines from various manufacturers. In
each instance, a small child was placed, climbed, or was helped to climb into a front loaded
coin machine and the door was closed behind him. The door locked, the machine started
running, and in one instance, the child was scalded to death.

WARNING 9 : Entrapment/Scald Hazards

—

• Never let a child climb into, operate, or play around this machine. Soon after door is
closed, door may lock and basket may fill with very hot water or spin.

• Do not open door if water is in machine.

®

Milnor

C4E and CGE coin operated washer-extractors have a door interlock which, to protect
against entrapment, permits opening the door during the first 60 seconds after closing the door
and starting the wash program. As additional protection against entrapment, once the door

locks, it may be unlocked by removing power at the wall-mounted disconnect switch or
circuit breaker, which must be part of the installation. The owner/manager must determine,

based on laundry operation, how to best address such an entrapment emergency. For example, the
owner/manager may wish to post clearly visible signs alerting customers to this, or, if an
attendant is always on duty, to make the attendant responsible for responding to such an
emergency.

iii. 2.

The Danger of Amputation Related to a Rotating Cylinder

A tremendous amount of energy exists in the rotating cylinder of any washer-extractor,
even at slow speeds. If someone tries to pull goods from a turning basket, the goods can
wrap around his/her arm, entangling the arm and twisting it off.

WARNING 10 : Amputation Hazard

—Turning basket can twist off arms.

• Never reach into or pull clothes from a turning basket.

• Machine pauses between reversals. Do not reach into basket until it remains stopped and
“U” flashes on display.

To protect against child entrapment, the controller used on coin machine models in the Milnor

®

C4E and CGE lines permit opening the door during the first 60 seconds after closing the door and
starting a wash program. The door locks after 60 seconds (see Note 1).

Note 1:

halts, the drain valve opens immediately, the motor stops driving the basket, and—if the machine still has
electric power—a brake is immediately applied to the basket. If the machine did not lose power, closing the
door will cause the wash program to resume where it was interrupted and the door lock delay time to be
reset so that the door can again be opened for 60 seconds from when the door was subsequently closed.

During the first 60 seconds of the cycle, the door may be opened. If this occurs, the wash program

Once the door locks, it remains locked, until one of the two following conditions occurs:

• When the wash cycle runs to completion without interruption, the door unlocks after the cycle
ends and the safety delay time expires. The safety delay allows time for the machine to coast
to a complete stop before allowing the user to open the door and retrieve the goods inside.

• If power is lost during the wash cycle, the door unlocks to allow the user to open the door and
retrieve the goods (see Note 2).

Note 2:

power is restored and the door is closed, the customer can start the wash cycle from the beginning by
inserting more coins, or the attendant can turn the
starting the machine without coins.

The Danger from Flammable Materials

Preface

WARNING 11 : Fire Hazard

—Never place items containing gasoline or other flammable

fluids in machine.

Washer-extractors are not designed to handle flammable materials. This includes goods
containing flammable substances as well as flammable cleaning materials such as solvents. In
either case, highly flammable vapors can be given off, especially when the material is heated.
Any source of spark or flame, such as the machine's motor, can then ignite the vapors, resulting in
fire or explosion. Additionally, washing with water and detergent may not fully remove
flammable materials from the goods, posing a severe risk of fire when those goods are placed in a
dryer.

iv. Daily Test of Door Interlock

The C_E door interlock is designed to lock the door after the machine has been running 60
seconds with the door closed. Test this vital safety mechanism daily to verify that it is functioning
properly.

Notice 12

: Daily test of coin counter not required.

placards used on some older coin-operated models, is not required on current C_E models.
Current models require only the daily door interlock test.

CAUTION 13 : Scald Hazards

—Contact with hot bath liquor can scald you.

• During the following test, hold the door firmly closed as shown in Figure 3 to prevent the
door from springing open if the latch retracts during this test.

—This test, referred to in safety

Figure 3: Hold Door Shut when Testing the Door Latch Interlock

Verify the door locks as follows:

1. Permit the wash program to progress for 90 seconds, but not much longer.

2. Holding the door closed, attempt to depress the door latch handle.

a. If the latch retracts (if the door unlocks), remove the machine from service until the

problem is identified and corrected.

b. If the latch does not retract (if the door is locked), and assuming no other evidence of

safety problems exists, return the machine to normal operation.
