Mount a male coupling on the water tap.2. Connect (a) on the BA valve to the water tap.3. Mount a female coupling on the water inlet hose.4. Connect (b) on the BA valve to the water inlet hose.5. Connect the water inlet hose to the high pressure washer.6. Turn on the water and start the machine.At least once a year, check the function as follows:1. After work, switch off the high pressure cleaner.2. Close the water tap valve.3. Release the pressure in water the supply hose by triggering thespray pistol.4. Dismount the backflow preventer. Water has to come out of thedrain opening (c) (max. 100ml) to ensure separation of the potablewater.5. If this is not the case, try cleaning the BA valve or contact yourNilfisk representative.This high pressure washer/cleaner is only allowed to be con-nected with the drinking water mains, when an appropriatebackflow preventer has been installed, Type BA according toEN 60335-2-79.The BA valve can be ordered under number:• BA valve including GARDENA couplings: 106411177• BA valve including NITO couplings: 106411178• BA valve including GEKA couplings: 106411179• BA valve without couplings: 106411184The couplings can be ordered under number:• 3/4” GARDENA (a): 1608629• 3/4” GARDENA (b): 32541• 3/4” NITO (a): 1602945• 3/4” NITO (b): 1600659• 1/2” NITO (b): 1604669• 3/4” GEKA (a): 1718• 3/4” GEKA (b): 1311CAUTION• The backflow preventer can be mounted either vertically or hori-zontally, and the drain opening (c) must be mounted pointingdownwards.• Water flowing from the drain opening (c) must be able to flowfreely.• If there is a risk of running sands in the inlet water (i.e. from yourown well), an additional filter should be mounted between thewater tap and backflow preventer.• The length of the hose between the backflow preventer and thehigh pressure washer must be at least 12 metres (min diameter3/4 inch) to absorb possible pressure peaks.• As soon as water has flown through the BA valve, this water isnot considered to be drinking water any more.• Protect the backflow preventer to any exposure to frost.• Keep the backflow preventer clean, and free of dirt.
