CHEMICAL REQUIREMENTS
The
SAPPHIRE SCIENTIFIC MODEL Apex 570
Truck mount unit’s unique last step chemical injection system can
be used with a wide variety of water diluted chemical compounds, either acidic or alkaline, depending on the
work to be performed. We recommend using only
SAPPHIRE SCIENTIFIC
brand chemistry.
WATER REQUIREMENTS
Because hard water deposits will damage the plumbing and heat exchange systems on this unit, Sapphire Scientific
recommends that a high quality water softener be used in areas where the water hardness exceeds 3½ grains. If a water
softener is used, it must have a flow capacity of at least five (5) GPM or greater, without any hose constrictions.
The use of a water softening system will reduce maintenance and reduce down time caused by hard water scaling. It will
also enhance the performance of cleaning chemicals, which will result in greater efficiency in lower concentrations.
See the chapter in Section 3 of this manual for instructions on descaling your system.
NOTE:
Using lower service class oil or
extending oil change intervals longer
than recommended can cause engine
damage.
