Recommended Installation by a Professional Plumbing Contractor
Note: The use of petroleum base plumbers putty on our products will nullify the warranty. We recommend
the use of clear silicone sealing materials. Recommended deck hole Ø1.25.
1. Place the spout SHANK (1) through base RING (2) and center hole of mounting surface. Secure spout into place with
WASHER (3) and NUT (4), (align the WASHER (3) slot in direction of pop-up rod). See Figure 1.
2. Place flange NUT (5) and WASHER (6) on valve BODY (7). Insert BODY (7), (blue cold & red hot), through hole in the
mounting surface. Adjust and secure with additional WASHER (6) and flange NUT (5) so that the top of valve is 2-7/16"
(1090) & 2-9/16” (880C) above top of mounting surface. Before tightening down flange NUT (5), check HANDLE (15)
alignment by placing onto Valve (7). Any adjustments for rotational alignment must be made to the valve BODY (7), not
to the cartridge. See Figure 1.
3. Insert rubber WASHER (8) into TEE (9) and attach to spout SHANK (1). See Figure 2.
4. Connect large end of flexible HOSE (10) to side outlet of each valve BODY (7). Attach other end of HOSE (10) to
either side of the TEE (9). (Hand-tighten and secure each connection with a wrench ¼ turn.) See Figure 3.
5. Connect hot/cold water supply to appropriate 1/2” NPSM valve BODY (7), utilizing one of the three following types of
risers. Supply risers not included. See Figure 3.
a. 1/2” IPS flexible riser:
discard rubber nosecone WASHER (11), friction WASHER (12) and coupling NUT (13).
b. 3/8” or 1/2” OD bullnose riser: utilize friction WASHER (12) and coupling NUT (13).
c. 1/2” copper riser: utilize rubber nosecone WASHER (11), friction WASHER (12) and coupling NUT (13).
6. Place ESCUTCHEON (14) and HANDLE (15) to cartridge. Secure HANDLE (15) into place with SETSCREW (16). Any
adjustments for rotational alignment must be made to the valve BODY (7) - not to the cartridge. (Note: Allow mini-
mum spacing between HANDLE (15) and ESCUTCHEON (14) to prevent damage to the surface finish.) See Figure 4.
7. Remove drain PLUG (17) from FLANGE (18). Place FLANGE (18) and white WASHER (19) through sink drain open-
ing. (Clear silicone may be used in place of white washer.) From bottom side of sink, place cone shaped rubber WASH-
ER (20) onto FLANGE (18) and slide up against sink bottom. Note: Cone portion of WASHER (20) to face upward.
Next slide on clear flat WASHER (21) and secure with flange NUT (22). Place clear WASHER (23) into drain BODY
(24) & tighten to FLANGE (18). Apply thread sealant to TAILPIECE (25) and attach to drain BODY (24). Attach TAIL-
PIECE (25) to p-trap drain (not included). See Figure 5.
8. Place drain PLUG (17) into FLANGE (18). Insert pop-up ROD (26) through spout and secure to STRAP (27), approx-
imately 1" from end of ROD (26), with SCREW (28). Insert ball ROD (29) into the drain's rod opening, secure with ball
rod NUT (30). Adjust the rise of the plunger and CLIP (31) into place. Adjust ball ROD (29) and pop-up ROD (26) so
drain will open and close properly. See Figure 6.
9. Remove AERATOR (32) from spout, turn on water supply, and flush both valves until water is clear. Check for leaks and
make any final adjustments required. Re-attach AERATOR (32) to the spout.
