NOTES FOR EUROPEAN TRIM:
For European trim, add 3.75 inches/95 mm to the D, D1, and F dimensions to
account for the additional water motor alarm shutoff valve.
For 1 ½-inch/48.3-mm European trim, add 14.10 inches/358.14 mm to the “A”
dimension to account for the two Victaulic rigid couplings, the water supply
main control valve, and the grooved x grooved nipple with outlet hole.
For 2-inch/60.3-mm European trim, add 14.21 inches/360.93 mm to the “A”
dimension to account for the two Victaulic rigid couplings, the water supply
main control valve, and the grooved x grooved nipple with outlet hole.
