A2Z Ozone SP - Series - Manual (Page 7)

Schematic diagram of injector manifold point of installation with “Hartford loop”
DETAILS OF VENTURI INJECTOR MANIFOLD:
Attention: Install venturi with bypass valve on water recirculation pipeline. Arrow on venturi
MUST be set as the same direction as water flow.
Turn water pump on and close the by- pass valve until vacuum is created at venturi input.
Note1: Use the installed flow-meter to check vacuum -2 to -3 PSI (-0.14 to -0.21 bars) or place
finger over end of venturi valve to feel vacuum while adjusting the by-pass venturi valve. At this
point, the air is injected into the water line; you will observe the air as bubbles in the water of
the swimming pool.
MAIN POWER:
Use the power cable provided to connect the SP-Series to a properly rated and
grounded receptacle. If the ozone generator will be used where water is present, a
ground fault circuit interrupter must protect the circuit.
