As I see it QR should be used for both above and at the cloud. "UNLESS" this is a renovation of an existing system.

LH=QR sprinkler heads. _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
