Check condition of hose test machine. Make sure caps are on fire hose outlet connection Pressure up to 10% higher than service test needed. 330 Hold pressure for 3 minutes with pump off. TEST OF MACHINE DONE
12
Time to test hose Apply nozzle to no more than 300 ft of hose. Charge hose to 45 psi, make sure to discharge air from line. Check all couplings tighten with spanner. Raise pressure no more than 15psi per sec. until desired pressure is reached. Allow 1 minute of stabilization per 100ft Hold service test pressure for 3 minutes
13
INFO If you walk the layout stay 15 ft from the left side of the hose. The left side is defined as the side that is left when facing the free end Never stand in front of the free end of the hose, the right, and no less than 15 ft on the left side. Never straddle the hose.
