Repair Kits
The smaller torsion springs will not return the Àappers contained in the 40415.1, 40415.2, 40425.1 and 40425.2
kits to a fully closed position if the valve is mounted vertically or upside down. Ensure that these mounting positions are
avoided if the smaller springs are used with the 4041RK1, 4041RK2, 4042RK1 and 4042RK2 kits.
