Before turning water on during either rough-in or
trim-out, ensure that the cartridge retainer clip is
in place. The cartridge and retainer clip were
properly installed and tested
prior to leaving the factory.
While unlikely, it is possible
that due to handling the
retainer clip may not be
properly installed. If the
retainer clip is not properly
installed, water pressure could
force the cartridge out of the
casing causing personal injury
and/or water damage.
To Operate Shut-off Stops
This type is integral with casting, actuated by a
screwdriver, requiring a 90° turn to open or
close. When the screwdriver slot is vertical the
stop is closed; when horizontal the stop is open.
MAKE SURE ALL WATER
SUPPLIES ARE OFF.
Rough-In
Install the casting with the arrow pointing up or
the word “TOP” facing the ceiling. If the valve is
used for shower only, plug the bottom outlet. If
the valve is used for both a tub and shower,
connect the top outlet to the shower and the
bottom to the tub spout. Secure all pipes and the
shower ell and/or tub drop ell. Use Teflon tape
on all threads.
Caution: This valve is equipped with the
Moen long-life POSI-TEMP
cartridge
designed for smooth, trouble free operation.
When soldering do not heat valve any higher
than necessary. Overheating may damage
the cartridge or rubber stops. Following this
direction will allow you to solder without
removing the cartridge or rubber stops.
Warning: The cartridge and rubber stops
MUST BE REMOVED before brazing or
resistance (electric) soldering.
Flushing
Important: Before closing wall openings,
pressure test valve and complete system using
flushing instructions.
Pipe chips, sand and other solids found in new
and renovated plumbing can damage the sealing
surfaces of the cartridge causing leakage or
spool blockage. To avoid damage,
DO NOT
TURN ON SUPPLY VALVES
until instructed.
Make sure both hot and cold supplies are off.
Rotate cartridge stem until the notch flat points
up to relieve pressure and insure complete shut-
off. Remove the cartridge (see Disassembly).
Slowly turn on both hot and cold supplies and
flush out the body and lines. Close the hot and
cold supplies and replace cartridge (see
Reassembly). Turn on both supplies and check
the system for leaks.
If the balancing spool becomes stuck, apparent
during the trim-out test, the valve will only deliver
a trickle of water or will only deliver hot or cold
water. If this occurs, proceed as follows:
Make sure that both hot and cold service lines
are ON and ensure that the integral stops are
open (stop models). The valve will not operate
unless both supplies are on.
If the valve still does not function properly, turn
off both hot and cold supplies and remove
cartridge. The inner spool in the cartridge should
shake back and forth freely. If this does not
happen, remove the stem assembly from the
cartridge sleeve, remove the cap from the
assembly and remove the balance spool.
Carefully clean any foreign material from the
balance spool and stem assembly and
reassemble. Caution: DO NOT DAMAGE O-
RINGS. If the spool still does not free up,
replace the entire cartridge.
Make sure the o-rings are free of foreign material
and are lubricated. Reassemble stem assembly
into cartridge sleeve. Reassemble cartridge into
valve (see Reassembly). Turn on both water
supplies. The valve should function properly.
Slip-Fit spouts
C.C. SPOUT:
The Moen slip fit spout is designed with an o-ring
seal, specifically for installation with copper
water tube. Lookout must be free of burrs inside
and out. The edge must not be rolled. The
outside surface must be free from nicks and
scratches.
Press and twist the spout onto the lookout
upside down. Tighten clamp screw with a 5/32”
hex wrench until it starts to bind. Correctly
position spout against the wall and tighten by
hand. Further tightening with pliers or hex
wrench is not needed. Do not overtighten.
IPS SPOUT:
CAUTION:
This spout is ABS plastic and will
crack when in contact with some pipe thread
compounds. We recommend using Teflon Tape.
Screw tube spout onto pipe and tighten by hand.
If final turn by wrench is needed, use small
wrench with smooth jaws or pad wrench teeth
with rag. Pull outward to avoid scratching wall.
DO NOT INSERT TOOL INTO SPOUT END TO
TURN SPOUT.
