Connect water to the G4. ¾" hose is the best but you can also use ½". Turn on water.
G4 water connector, connect water from water supply here
Close all the water release valves on the G4, they are the ones leaking water when the water was turned on. If
nothing was leaking water then valves were already closed. Check water pressure. Needs to be at least 2.5 lbs, if
lower than 2.5 then need a water booster pump if one is not built into this particular machine. If pressure falls
below 2.5lbs then machine will shut off.
