2.O4 Tubing
With all the components mounted, they can be connected with the
delivery hoses. A flexible, reinforced, transparent, chemically-compatible
hose of the proper inside diameter is recommended. On U.S. systems the
delivery hose connections are 1/2” barb and must be secured with worm-
gear hose clamps. Check the fittings on the washers and the chemical
drum pickup systems, in case an adapter will be required.
Water Inlet
The product delivery system will require
water flow of about 1 to 2
gallons per minute (gpm)
at a dynamic (valves open)
water pressure
of 20 to 30 psi (1.5 to 2 bar)
. Do not use a water source that feeds other
equipment, if during that feed flow/pressure drops below the requirements.
Water of a higher pressure will require a pressure regulator
before
the connection to the Dositec system. If necessary, install the appropriate
Hydro Booster Tank to supply water at the proper flow and pressure.
Chemical Pickup
These are the hoses that connect the chemical drum pickup system to the Collection Manifold on the main panel. They allow
product to be drawn into the delivery channel by the pneumatic pump during the dosage cycle.
Consider how you want the chemical drums positioned to avoid having incompatible chemicals too close together, and to
allow a neat routing of the hoses to the collection manifold on the main panel. Notice the water inlet is always the “first” valve
(in the direction of flow) on each collection manifold. Also notice how the products are numbered and connected, starting next
to the water, then progressing in the direction of the flow.
