3.1 Safety and Best Practice When Loading and
Unloading
BNWUUO02.C01 0000214781 B.2 E.2 C.2 9/11/20 8:44 AM Released
If you are responsible to load and unload the machine:
• Put safety first.
• Use correct load sizes.
3.1.1 Loading and Unloading Safety
BNWUUO02.C03 0000214879 B.2 E.2 C.2 9/11/20 8:46 AM Released
Loading and unloading activities have associated risks that are addressed by safety placards on
the machine. Before you use your Milnor®washer-extractor for the first time, read the safety
placards. If there is anything you do not understand, get clarification from your supervisor or
laundry management.
There can also be other risks associated with the type of laundry facility and the allied (non-Mil-
nor®) equipment you use, such as laundry carts, sling systems, chemicals and chemical systems.
Milnor®advises you to obtain and read the safety literature provided for your facility and for all
equipment you use.
Examples of possible risks related to the type of laundry facility or to allied equipment are:
• goods handling:
– sharp objects such as scalpels and syringes left in OR gowns
– biological contamination in patient gowns and diapers
– just processed goods that are hot to the touch
– poisonous or flammable chemicals in the soiled goods
• laundry carts of the wrong size that cause unnecessary effort in loading or unloading
• laundering chemicals:
– leaks in supply lines
– skin or eye irritation from contact with spilled chemicals or chemical containers
3.1.2 Load Size Best Practice BNWUUO02.C02 0000214780 B.2 E.2 C.4 9/11/20 8:47 AM Released
For your machine, there is a correct load size for each type of goods you process.
Pellerin Milnor Corporation 9

load size the dry weight (in pounds or kilograms) of a load of goods. Specific goods types can
require specific load sizes and these can vary significantly.
capacity the load size rating for a washer-extractor, as stated in the specifications shown on the
product brochure. This rating does not reflect factors such as goods type and soil content.
You will get the best performance from your machine if you use the correct load sizes. Under-
loading can make it difficult for the machine to distribute (balance) the goods before extraction.
This can cause excessive recycles (when the machine repeatedly tries to distribute the goods). Oc-
casional small loads may be necessary, but keep these to a minimum. Over-loading can put in-
creased stress on machine components and reduce wash quality.
CAUTION: Incorrect load sizes — can cause premature machine wear, excessive re-
cycles (which extends formula time), and poor wash quality.
�Use a chart of goods types and load sizes from your supervisor or laun-
dry management.
�Minimize the number of small loads.
�Use a scale to determine when a load is the correct size.
�On a divided-cylinder machine, put approximately the same weight of goods in each
pocket.
When your machine was purchased, your Milnor®dealer worked with your laundry personnel to
determine the optimum machine for your needs. This took into account factors such as the types
of goods to be washed and the expected soil content of the goods, which can cause the correct
load size to vary greatly among goods types. For example, the more bulky the goods, the smaller
the permissible load size. The correct load sizes will be what was previously determined when
the machine was purchased. If you do not already have a chart of the goods types to be processed
and their correct load sizes, request one from your supervisor or laundry management.
3.1.2.1 Weighing Goods
BNWUUO02.C04 0000255516 B.2 E.2 11/19/20 10:15 AM Released
Build loads of the correct size for the best performance from your machine. The most accurate
method to build loads of the correct size is to weigh each load as you assemble it.
You can weigh the goods using a separate laundry scale, weighing-type load conveyor, etc. If
your machine is connected to a Mildata®network and configured to pass weight data, be sure to
record the weight of each load so that you can enter it into the Remote Formula window (Figure
7: Remote Formula Window, page 15 ) before you run a formula.
