11.Reinstall the pump in the isolation enclosure. Use the two mounting holes to the left of the holes used previously, to allow clearance for the fluid regulator.
12.Connect tube (A1) to the air inlet of fluid regulator (504). Connect tube (507) to the pump air inlet.
13.Connect the waterborne fluid hose to the fluid regu- lator outlet fitting (501).
