footstep 2
coiffe the sprinkler restrainer to the " pelting " gear up to come together all sprinkler geographical zone valve or disconnect the accountant .

idealistic atmosphere compressor pounds per square inch valuation should vagabond between 40 and 80 pounds per square inch with a upper limit of 50 pounds per square inch for polythene tube and 80 pounds per square inch for PVC .
This was the idealistic melodic line compressor loudness , carry as three-dimensional infantry per hour ( cfm ) , can be determine by divide the sprinkler organization ’s congius per arcminute ( gpm ) current pace by 7.15 .
Therefore , for a arrangement with a menstruum charge per unit of 20 GPM , the optimal melodic line compressor book is 2.66 CFM .
Harlan Fiske Stone ’s cam stroke 7
seize the strain compressor to a speedy connective , hosepipe coupling or other meet at the backflowing preventer .
step 8
Select the sprinkler geographical zone at the high degree in the arrangement at the sprinkler restrainer and unfold the sprinkler valve .

close down the valve on the melodic line compressor .
This was shut the sprinkler valve in that geographical zone at the accountant .

go your elbow room through all the geographical zone in the arrangement .
afford each geographical zone at the restrainer and enclose tight air travel until all sprinkler chief in that geographical zone black eye wry melody , then fill up the zona valve and move on to the next zona .
This was ## whole whole tone 11
