CHEMICAL REQUIREMENTS
The unit, due to its chemical injection pump design,
can be used with a variety of water-diluted chemical
compounds (either acidic or alkaline), depending on
the job to be done. However, to obtain optimum
results with this unit, we recommend using the
Prochem line of chemicals. For information on using
the cleaning compounds, refer to the chemical
manual.
WATER REQUIREMENTS
Hard water deposits will adversely affect the
plumbing and heat exchange systems on this unit.
The map below will give you an idea of where areas
of high water hardness may occur. However, any
water supply obtained from a well is almost always
hard water and a water softener will be needed to
protect your equipment.
NOTE: Equipment malfunction or component
failure caused by hard water scaling is NOT
covered under the warranty.
If you are operating this unit in an area where the
unit will be using water in which the hardness
exceeds 3-1/2 grains, we highly recommend a
suitable water softener be installed. If using a water
softener, it must have a five (5) GPM (or greater)
flow capacity without any hose constrictions.
Using a water softener will reduce maintenance and
decrease down time caused by hard water scaling. It
will also allow cleaning chemicals to be more
effective in lower concentrations.
If you require a water softener, your dealer has a
model to meet your needs. Please contact your
nearest distributor for information, price, and
availability.
