2.4.4. Door Bearings (Grease)
Grease the upper and lower door hinge bearings with Mobilith AW2. Refer to Fig. 5-3.
2.5. Auto Steam Exhaust (ASE) Assembly
ASE Blower Motors are lubricated for life. No additional lubrication is required.
2.6. Chemical Concentration
There are two methods to test chemical concentration and maintain the proper chemical
charge:
1. Titration Test
Titration is the estimation of the strength of a compound by measuring the
amount of another compound of known strength that is required to produce
an observable reaction.
Almost all titration kits supplied with cleaning compounds use
phenolphthalen (indicator P) as a reactant, and an acid (hydrochloric or
phosphoric) as a neutralizer. The indicator P turns red or pink or blue when
added to a sample of the solution. By counting the drops of acid it takes to
turn the solution back to its original color, you can arrive at a good
estimate
of the chemical concentration.
Titration Testing Guidelines :
·
Perform a titration test weekly.
·
Contact your chemical supplier for test kits.
·
Use a kit designed specifically for your chemical.
·
Follow test kit instructions.
·
Add chemical based on the results of the test.
When you perform a titration test , do the following:
1. Allow the sample solution to cool to room temperature.
2. Filter the cooled solution to remove impurities.
3. Hold the titration reagents vertical when you add drops to the
sample. This ensures "size accuracy" of the drops coming
out of the reagent bottles.
