AVOID DAMAGE TO YOUR WASHER !
READ AND FOLLOW THESE INSTRUCTIONS !
EMC Parts Washers are Designed for Use
with Non-Flammable, Water-Soluble SOAP,
with Rust Inhibitors !
DO NOT use Petroleum Solvents !

A. SOAP & WATER SOLUTION :
1. Check with your local chemical suppliers as to the
proper soap to use for your cleaning situation.
Follow your individual soap manufacturer instructions and precautions as to
the use and handling of Soap products and Hot water, and the use of
protective gear such as: face shields, rubber aprons, gloves, boots, etc., to
prevent injury from contact with Soap and HOT parts.
2. DRY SOAP MUST BE PROPERLY MIXED with WATER !
! CAUTION !
Undissolved Soap, clumped up on floor of washer, can create
a chemical reaction, capable of corroding through the steel
floor! . . .
(see following section
:
B. BULLETIN
)
A. Soaps must be
Pre-mixed
with warm water
,
in a container or bucket, (allow up to 30 min.) . . .
. . . OR . . .
B. Soaps can be Pre-mixed in the washer, as follows:
1) Fill the Washer with Water, to the proper level
( see section: C. WATER LEVEL )
2) Set Thermostat to 160º F, and bring the water up to
Operating Temperature (usually 160º F in most cases)
3) Place proper amount of soap in a pan on the Turn Table.
-
Check with your Soap Supplier
*
for correct
amount of soap to use.
4) Run Washer for up to 30 minutes, until soap is properly mixed

B. BULLETIN:
RUST & CORROSION of PARTS WASHERS
with Carbon Steel Components
It is well known that ordinary carbon steel exposed to plain water will oxidize
or ‘rust’. The vast majority of
Water Based Solution Automatic Parts
Washers
are made of Carbon Steel. Alth
ough Stainless Steel is available, it’s
cost often makes it prohibitive.
Therefore, carbon steel Parts Washers are designed for use with
water and
soap with rust inhibitors.
The rust inhibitors not only protect the washer
cabinet but also the customers steel and iron items being washed in it.
Without the proper rust inhibitor, the washer cabinet and the parts you wash
in it, will rust!
There are basically 3 reasons why a parts washer will rust
:
1. Using a soap, which has
no
rust inhibitor in it.
- Make sure the product being used is designed for this application.
-
If pressed too hard for price, some suppliers will sell a “cheaper”
product (i.e. laundry soap).
2.
Too little concentration of soap, - which means too little rust inhibitor.
- Check your water to soap mixing ratio as recommended by the soap
manufacturer / supplier.
- Soap may be carried out on parts being washed.
- If you only add make up water without additional soap, you have in
turn reduced the soap concentration.
3.
Often, operators will dump powdered soap into the parts washer with no
concern about whether the soap is properly mixed with the water
. . .
Despite clear instructions to the contrary in our operator’s manual !
- The unmixed soap will settle on the washer floor, turning into what
may look like
“ a chunk of concrete”
or “a slab of salt”.
A chemical
reaction between the block of solid soap and the floor of the washer
can corrode holes in the floor of the washer.
- Also, since the soap, and its rust inhibitors, are on the floor and not
mixed with the water, the interior of the washer may begin to rust.
To wrap up, quite simply, steel will react with what it comes in contact with.
Over the years and thousands of washers later, we have only seen steel
rust when exposed to things which ordinarily cause rust, . . . .
. . .
such as
.
. .
water without rust inhibitors !

C. WATER LEVEL:
1. Fill and Maintain Water Level to top of Filter Bags.
a) Open the washer door and fill the tank with water using a
hose or buckets.
b) Maximum Water Level is up to the top of Filter Bags, or
in the range of the 2” ball valve Variable Weir skimmer.
c) Washer is equipped with a Low Water Level, Float Switch,
Shut-Off System.
. . . Do Not rely on the Low Level Switch for
maintenance of Water Level !
d)
Water Level should be checked each day, until your water
usage pattern is established.
HINT:
If Washer fails to operate, check if Water Level is too Low !
WARNING !
If Water Level drops too Low, heating elements can be
damaged !
