Installation Guide

INSTALLATION
For Complete Valve Installation, Start Here.
For RESS Retrofit Installations, Start at Step 5.
Step 1 — Install Control Stop (Figures 2 & 3)
Install the Sloan Bak-Chek Control Stop to the water supply line with the
outlet positioned as required.
For Sweat Solder applications, refer to the following instructions and
Figure 3:
1A. Measure distance from finished wall to centerline of fixture spud. Cut
water supply pipe 1¼" (32 mm) shorter than this measurement.
Chamfer O.D. and I.D. of water supply pipe.
1B. Slide Threaded Adapter onto water supply pipe until end of pipe rests
against shoulder of Adapter. Sweat Solder Adapter to water supply pipe.
1C. Determine length of Covering Tube by measuring distance from finished
wall to the first thread of Adapter (Dimension “X” in Illustration 1C
below). Cut Covering Tube to this length.
1D. Slide Covering Tube onto water supply pipe. Slide Wall Flange over
Covering Tube until it rests against the finished wall.
Install the Sloan Bak-Chek Control Stop to the water supply line with the
outlet positioned as required. Refer to Figure 2.
Step 2 — Flush Out Supply Line (Figure 4)
Open Control Stop. Turn on water
supply to flush line of any debris or
sediment. Close Control Stop.
Step 3 — Install Vacuum Breaker Flush Connection
(Figure 5)
Slide the Spud Coupling, Nylon Slip Gasket, Rubber Gasket and Spud
Flange over the Vacuum Breaker Tube. Insert Vacuum Breaker Tube into
fixture spud. Hand tighten Spud Coupling onto fixture spud.
If cutting Vacuum Breaker Tube to size, note that Critical Line (C/L) on
Vacuum Breaker must typically be 6” (152 mm) above fixture. Consult Code
for details.
Step 4 — Install Flushometer (Figures 6 and 7)
SLOAN ADJUSTABLE TAILPIECE (Figure 6)
The Sloan Adjustable Tailpiece
compensates for "off-center" roughing-in
on the job. Maximum adjustment is ½"
(13 mm) IN or ½" (13 mm) OUT from the
standard 4¾" (121 mm) (centerline of
Flushometer to centerline of Control Stop).
IMPORTANT: WITH THE EXCEPTION
OF CONTROL STOP INLET, DO NOT
USE PIPE SEALANT OR PLUMBING
GREASE ON ANY VALVE OR OPTIMA
PLUS COMPONENT!
Refer to Figure 7
Insert Adjustable Tailpiece into Control Stop. Wet O-ring Seal with water to
lubricate. Secure by hand tightening Tailpiece Coupling.
Align Flushometer body on top of Vacuum Breaker Flush Connection and
secure by hand tightening Vacuum Breaker Coupling.
Align Flushometer body and securely tighten Tailpiece Coupling, Vacuum
Breaker Coupling and Spud Coupling, respectively.
IImmppoorrttaanntt NNoottee::
Use a smooth jawed wrench to secure all couplings. This will
eliminate damage to chrome or special finish that normally occurs when slip-
joint pliers, pipe wrenches or other "toothed" tools are used.
