the use of clear silicone sealing materials. Recommended deck hole
Ø 1-3/8” for center hole and
Ø 1-3/8” for two side holes.
1. Place flange NUT (2),and SPACER (3) on VALVE (4). Insert VALVE (4), (blue/cold and red/hot), through the hole in the
mounting surface (5) and thread into inverted mounting NUT (1) until it bottoms out. The top of VALVE (4) will be
1-3/8” for 3100 & 3120 above the top of mounting surface. Before tightening down flange NUT (2). check alignment
of HANDLE (14). Any adjustments for rotational alignment must be made to the valve BODY (4), not to the CAR-
TRIDGE (15). Place escutcheon (5a)over VALVE (4). See Figure 1 and 1a.

nection with a wrench ¼ turn.) Repeat on other side. See Figure 2.

ment must be made to the valve BODY (4), not to the CARTRIDGE (15). Repeat on other side. See Figure 4.
