Symmons Carrington SRT-4470 Installation And Service Instructions

Roman Tub Faucet
Installation and Service Instructions
Compliance: ASME A112.18.1/CSA B125.1

Installation Procedure:

Drill three 1 1/4" holes into the deck (maximum deck
1.
thickness 1-3/8" ).
Cut 1/2" copper tubing (RT-108) to length required.
2.
Example: If a 10" valve center to valve center is required,
the tubing should be cut to 3 7/8". The maximum overall
center to center dimension with supplied tubing is
18-1/4".
For greater widths the installer will need to provide their
own tubing.
Ensure the centerbody nut (RT-103N) is threaded onto
3.
the centerbody (RT-100) and then install 3/8" plug (RT-
105).
Solder the branch of the tee (HPT-10) to the centerbody.
Cut to proper length and solder the two 1/2" copper
tubing (RT-108) into the run of the tee (HPT-10) and
into the valve bodies (RT-103).
Push assembly through deck holes from the bottom with
4.
hot on left.
Slip retaining plate (RT-101) over the centerbody (RT-
100) making sure the retaining plate (RT-101) slides over
the flange of the centerbody.
Then turn the retaining plate 90 degrees under the
nut on the centerbody (RT-100) to hold in place. The
soldered assembly should be held in position on the
deck making sure the hot cartridge is on the left.
Ensure the tops of the valve bodies measure
approximately 1-7/8" from the finished deck by
adjusting centerbody and valve body nuts (RT-103N).
Note: If tile or finished surface will be installed while
the plumbing is in a "roughed in state" the retaining
plate (RT-101) should be shimmed the thickness of the
finishing material.
Tighten the centerbody nut (RT-103N) under the deck.
5.
Thread valve body nuts (RT-103N) up to base of deck
but do not tighten.
Solder 1/2" hot and cold supplies to valve bodies
6.
(RT-103).
The system can be tested at this time.
7.
Remove plug (RT-105) when the spout (RT-135) is to be
assembled onto the faucet.

Caution: Be sure to turn off hot and cold water supplies before
installing or servicing faucet.
Grease o-ring (T-2) in the bore of the spout.
8.
Assemble spout onto centerbody with gasket (RT-165)
under the spout.
Tighten spout (RT-135) in place with set screw
(SC-15A).
Important: O-ring (T-2) can be damaged if set screw
(SC-15A) is overtightened during installation. If faucet
begins to leak from under spout, replace o-ring (T-2).
Thread handle escutcheons (RT-104) onto valve bodies.
9.
Thread collar (LN-112) onto the valve body until it
reaches the escutcheons (RT-104).
Tighten three body nuts (RT-103N) securely.

Faucet handle installation:

10.
Place handle on valve spindle and thread screw
(LN-121A) into valve.
It is very important to thoroughly flush the supply lines
11.
to prevent foreign matter, i.e. copper chips, sand, stones,
etc. from damaging the sealing surfaces of cartridge.
Remove aerator and open hot and cold to full open then
open both supplies.
Let water run through hot and cold long enough to flush
supply lines thoroughly.
Shut off faucet and replace aerator. Check for leaks.

Cartridge Replacement (KN-113 or KN-114)

Remove plug button (LN-243C or LN-243H), loosen
1.
Philip head screw (LN-121A) and remove handle (LN-
177).
Remove collar (LN-112) by turning counter clockwise.
2.
Caution: Do not use wrench as this may damage the
surface finish.
Place wrench on cartridge hex nut (KN-113, KN-114).
3.
Turn wrench counter clockwise until cartridge is
removed.
Install new cartridge. Turn cartridge with wrench until
4.
cartridge does not turn easily then turn 1/4 to 1/2 turn
further. Reassemble handle in reverse fashion.
