HYDRAULIC SYSTEM
Overview
The hydraulic system in the Synesso™ is comprised of all parts through which water flows
starting with where it enters the machine from the water treatment/filtration system. This
chapter will detail the flow of water and some of the associated electrical componentry.
Water requirements:
Proper water filtration and regular filter changes are a requirement to keep your fac -
tory warranty valid and your machine functioning properly. It is highly recommended
that you contact a professional water filtration specialist in your area and have your water
tested to determine the proper filtration system. Good water treatment systems will remove
tastes and odors as well as particulate matter that can block valves and cause issues with
the machine. Hard water will cause scale to develop inside the machine which adversely
affect the water flow and heating processes, so it is vital to have water hardness in the
recommended range. It is important to note that many municipalities change their water
sources throughout the year, so additional water tests may become necessary.
Water Standards to keep your warranty valid:
Total Dissolved Solids (TDS) 30 to 200 ppm (parts per million)
Total Hardness -(in ppm) Less than 85 ppm
Total Hardness – (in grains per gallon) 3 to 5 grains (divide ppm by 17.1 to get gpg)
pH 6 pH to 8 pH – above 8 is very harmful
Chloride 0 ppm – any Chlorides can be corrosive and harmful
Total Alkalinity Less than 100 ppm
Chlorine 0 ppm
Iron 0 ppm
Synesso™s utilize 3/8” braided stainless hoses (supplied with machine) to connect to the
water treatment system. Once the machine is set up and the water quality is checked, the
machine is ready to be connected to the water treatment system. The water then passes to
the pump and motor.
On single inlet machines, the water then travels through one hose to the machine and sup-
plies both the coffee boiler system and the steam boiler.
On dual inlet machines, the water splits off at the pump: the water for the coffee boiler goes
through the pump and the water for the steam boiler splits off and goes through a separate
line to fill the steam boiler. The next 3 pages show the dual, single, and Hydra inlet water
paths.
