Installation Schematics Measuring for Ideal Tub/Shower Performance

Installation of this product at non-recommended measurements may leadto issues such as water discharge from the showerhead during tub fill mode.

Tub/Shower

Position the valve body 32 inches from the floor of the tub basin. The shower arm should be placed 78 inches above the floor of the tub basin (recommended installation of the shower arm is with a flanged elbow fitting – not included – and attached to a wood brace). The tub spout is to be no less than 6 inches and no greater than 11 inches below the valve. If installing a threaded tub spout, connect to the valve with 1/2 inch pipe or 1/2 inch copper tubing with a threaded adapter. If installing a slip-fit tub spout, connect to the valve with only copper tubing – no threaded adapter is needed.

See step 4.3 for tub spout tube length.

Screen Shot 2019-02-15 at 3.55.43 PM.png

Shower Only

The center of the valve should be 45 inches to 48 inches above the shower stall floor. The shower arm should be placed 78 inches above the floor of the shower stall floor (recommended installation of the shower arm is with a flanged elbow fitting – not included – and attached to a wood brace).

Installing Your Valve

Thin Wall Installation

  1. The “Thin Wall” method is used when the tub/shower wall is less than 1/4 inches thick (such as fiberglass tub surround) and will be the main source of support for the valve.
    The plaster ground (E) remains attached to the valve. A 2-1/4 to 3-1/2 inches diameter hole is cut thru the wall for this method.
  2. Break away the black plastic protective cover using pliers and rotating clockwise.
  3. Remove the escutcheon screws (G), place product identification label (Z) on back of escutcheon, place the escutcheon (F) over the stop tube (B). Then reinstall the screws (G). A gasket on the back of the escutcheon provides a seal against the finished wall.

Thick Wall Installation

  1. The “ThickWall” installation method is used when the tub/shower wall is greater than 1/4 inches thick.
    “ThickWalls” are usually built up with materials usch as cement board, dry-wall, tile, etc. The valve is secured by straps holding the water inlet lines to the framing memebers (2X4’s) as shown in steps 2.1 and 2.2. The valve also features mounting holes to screws the valve to a cross member attached behind the valve if desired.
    The plaster gorund (E) is positioned so that it is flush with the finished wall. This ensures that the valve will be at the correct position to accept the trim. The hole in the wall should be the same size (4-1/2 inches) as the plaster ground (E). This hole will allow access for future servicing if necessary.
  2. Attach the plaster ground (E) to the valve body using the 2-3/16 inches escutcheon screws (G). Keep the plaster gorund (E) attached to the valve until the valve has been positioned and secured. Once the valve is secured in place, remove the escutcheon screws (G) and the plaster ground (E). Keep the escutcheon screws (G) for installation of the escutcheon (F) and discard the plaster ground(E).
  3. Place production idetification label (Z) on back of escutcheon, place the escutcheon (F) over the stop tube (B) then re-install the screws (G). A gasket on the back of the escutcheon provides a seal against the wall.

Moen suggest testing for functionality and checking for leaks before sealing walls. An access panel behind the valve is recommended.

  • Thread hose (X) onto handheld showerhead (Y).

Threaded Tub Spout Installation

Screen Shot 2019-02-18 at 9.44.35 AM.png

If this is a shower only installation, skip to step 4.4

IPS (threaded) spouts are designed to screw onto a pipe with 1/2 inch male pipe threads. To determine the proper pipe length, measure from the inside elbow shoulder to the wall (y) and from the threaded adapter inside of the tub spout to the base of the tub spout (x), then add 1/4”. Place thread seal tape around the pipe threading adn a sealant (plumbers putty or caulk) around the base of the pipe to prevent leaking behind the wall.

Slip Fit Tub Spout Installation

Screen Shot 2019-02-18 at 9.47.05 AM.png Screen Shot 2019-02-18 at 9.47.33 AM.png Screen Shot 2019-02-18 at 9.47.59 AM.png

Some models may feature a slip fit installation with no threaded adapter in the tub spout. For these installations, slip the tub spout onto pipe pointing up and slightly tighten the set screw. Rotate tub spout to final position and fully tighten set screw in place.

Now you are ready to attach the handle. Rotate so the notch at the end of the stem is facing down towards the drain. Insert the key stop (C) and the adjustable limit stop (D) into stop tube as shown.

For Lever Handles Installed with Plastic Handle Adapter (J)

Screen Shot 2019-02-18 at 9.52.30 AM.pngPosiTemp_Install35.png

  • If this is a lever handle that attaches with the lever handle adapter (J), attach the plastic handle adapter (J) to the cartridge stem using the 1/2 inch adapter screw (K). Make sure the ridges on the back of the adapter (J) are to the left of the tab on limit stop (D).
  • Place the lever (L) on the lever handle adapter – the stop on the back of the lever handle adapter (J) should be in the 11:00 position when being attached with the lever pointing down.

Other Possible Handle Type Installations

Screen Shot 2019-02-18 at 9.56.02 AM.png

  • Place the knob handle (P) – onto the cartridge - make sure the indicator on the knob is pointing down.
  • Place the lever (T) onto catridge – make sure the lever is pointing down.

Screen Shot 2019-02-18 at 9.59.28 AM.png Screen Shot 2019-02-15 at 3.41.48 PM.png

  • Turn on the hot and cold water supply to check for leaks and set temperature limit stop.
  • Rotate the lever OR knob counterclockwise until the water is to the maximum desired temperture, not to exceed 120 degrees F (49 degrees C). Seasonal maintenance of the maximum outlet temperature may be required due to changes in groundwater temperature. TURN LEVER OR KNOB TO THE OFF POSITION ONCE THE TEMPERATURE IS SET.
  • If temperature exceeds 120 degrees, go to step 5.3
  • If temperature is less than 120 degrees, go to step 5.4

Screen Shot 2019-02-18 at 10.01.18 AM.png

  • Remove the lever (L) and lever handle adapter (J). Note the position of the stop. Position the adjustable temperature limit stop (D) so the lever or knob stops at the position. The prevents the lever or knob form being turned into an unsafe temperature.
  • Remove the knob handle (P). Note the position of the stop. Position the adjustable temperature limit stop (D) so the lever or knob stops at that position. This prevents the lever or knob from being turned into and unsafe temperature.
  • Remove the lever (T). Note the position of the stop. Position the adjustable temperature limit stop (D) so the lever or knob stops at that position. This prevents the lever or knob from being turned into an unsafe temperature.

Screen Shot 2019-02-18 at 10.02.47 AM.png

  • After setting the adjustable temperature limit stop to the desired position, remove the lever (L), reattach the lever handle adapter (J), adapter screw (K), and lever (L) – make sure ridges on back of (J) are to the left of the tab on (D).
  • After setting the adjustable temperature limit stop to the desired position, reattach the double D washer (O) and knob (P) – make sure indicator on the knob is pointing down.
  • After setting the adjustable temperature limit stop to the desired position, reattach lever (T).

Screen Shot 2019-02-18 at 10.08.13 AM.png

  • Using 7/64 inches hex wrench (N), insert and tighten hex screw (M) into lever (L).
