checks detergent concentration of solution in sump. Alkaline
detergent is then injected into sump until solution reaches set
concentration level. Alkaline detergent solution is monitored and
maintained at set concentration level while recirculating and
spraying over load.

If using acid detergent with injection system, acid detergent is auto­matically injected into chamber sump during Acid Wash phase of a
cycle.

• Hot detergent solution from acid detergent tank fills sump until
required solution level is attained. Once sump is full, control
checks detergent concentration of solution in sump. Acid

Values with Access

Code Enabled

Access code feature is used to prevent unauthorized changes to
parameters of designated cycles and/or operating values by unau­thorized operators. With this feature, access to cycle values may be
selectively limited to authorized operators only, depending on secu­rity needs of washer environment. When access code is enabled,
only authorized operators can change operating values.

ADVANTAGES OF ENABLING OR DISABLING ACCESS CODE:

Enabling or disabling access code can impact efficiency of washing
operations. For that reason, supervisor should carefully consider

choices: if access code is ON, supervisor can ensure operators use
washer within predetermined parameters; if access code is OFF,

supervisor can allow operators more flexibility in determining which
cycles to use and how to use them. Deciding factor should be what
works best for facility’s operation.

WARNING – CHEMICAL
BURN AND/OR EYE INJURY
HAZARD: Washer chemicals
are caustic and can cause
adverse effects to exposed
tissues. Do not get in eyes,
on skin, or attempt to swal­low. Read and follow precau­tions and instructions on
chemical label and in Material
Safety Data Sheet (MSDS)
prior to handling detergent
containers, or servicing
detergent injection pumps,
tank, and lines. Wear appro­priate Personal Protective
Equipment (PPE) whenever
handling chemicals or servic­ing chemical injection
pumps, tank, and lines.

WARNING – SLIPPING HAZ­ARD: To avoid slippery floor
conditions, keep floor dry.
Promptly wipe up any spilled
liquids or condensation. If
spilled liquids are deterge nts
or other chemicals, follow
safety precautions and han­dling procedures set forth on
detergent or chemical label
and/or Material Safety Data
Sheet (MSDS).

CAUTION – POSSIBLE
EQUIPMENT DAMAGE:

• When choosing a deter­gent, select one with a low
chloride content. Deter­gents with a high chloride
content can corrode stain­less steel.

• Always use non-foaming
chemical for effective
cleaning and proper pump
and water level control
operation. Follow manu­facturer’s recommenda­tions for amount of
chemical to be used.

6.7.2 Storing Thermal Paper Thermal paper is subject to fading with time, humidity, and exposure

to light.

It is manufacturer’s recommendation that thermal paper be stored in
a dark place with an average ambient temperature of less than 77°F
(25°C) and a relative humidity less than 65%. Under these condi­tions, paper remains readable for at least five years. It is recom­mended that if printed data is to be retained for periods of time
longer than five years (6 -25 years), an additional photocopy should
be made for record retention. In any case, a duplicate set of records
should be maintained in files of engineering or maintenance depart­ments.

Thermal paper begins to develop color at about 158°F (70°C); how­ever, under humid conditions it might begin to develop at an acceler­ated rate. If stored for 24 hours at 140°F (60°C), paper shows some
signs of development. It also shows signs of development if stored
for 24 hours at 113°F (45°C) and a relative humidity of 90%.

Do not store thermal paper next to other chemically treated papers ­such as pressure sensitive paper or other type of recording round
charts - as this may cause fading in print. If thermal paper is to be
stored in same area, always ensure it and other chemically treated
papers are kept in separate envelopes.

Thermal paper discolors when exposed to direct sunlight.
