WARNING

Prepare water supplies per ROUGHING-IN DIMENSIONS. Make sure the ﬁnished wall is between the minimum and maximum rough dimension.

ROUGHING-IN THE VALVE

Install VALVE at indicated height and depth. Make sure the "TOP" marking on the PLASTER GUARD is up.

Connect the hot and cold water supplies. Assemble all connecting pipes. Flush lines to remove any dirt. Connections are 3/4" NPT.

Assemble the connection pipe to one of the MIXED OUTLETS of the VALVE. Cap the other MIXED OUTLET. (Tub port is ﬁtted with a plug at the factory).

IMPORTANT! INSTALL ANY REQUIRED SHUT OFF OR DIVERTER VALVES INTO THE PIPING SYSTEM.

DO NOT SOLDER DIRECTLY TO THE VALVE BODY; THIS WILL DAMAGE THE TEMPERATURE CONTROL ELEMENT AND CHECK STOP VALVES.

Unscrew PLASTER GUARD SCREWS and remove PLASTER GUARD.

Check that arrow marking B points vertically upwards. If not, push the BLACK CLAMP on the SECURING RING to the right, pull off KNOB MOUNT and reinstall KNOB MOUNT with arrow "B" pointing upwards.

For 100 F adjustment, turn the water supply on. Turn KNOB MOUNT until the spout temperature is 100 F. Check that arrow marking A on the KNOB MOUNT still points upward after adjusting the thermostat to 100 F. If not, pull out the RED LOCKING DEVICE. Remove KNOB MOUNT by pulling it towards you while standing directly in front of the valve.

Reinstall the KNOB MOUNT so that the arrow marking A points upwards.

The maximum mixed water temperature is set at 109 F at the factory. This setting can be changed if desired.

Remove the TEMPERATURE LIMIT STOP (H shaped Black Plastic part). Reinstall it at the desired notch as indicated in the diagram to limit the maximum mixed water temperature to 104 F or 112 F.

Reinstall RED LOCKING DEVICE.

If the CHECK STOPS (4, 5) were removed during installation, ensure the hot and cold CHECK STOPS (4, 5) are not reversed. The hot CHECK STOP (4) has a red top and the cold CHECK STOP (5) has a blue top.

CHECK STOPS (4,5) are supplied in the open position. Closing using 5/32" (4 mm) hex wrench to pressure test and to check for leaks.

Reassemble PLASTER GUARD (2) and FINISH WALL.

Beware of Freezing. No water should remain in the MIXING VALVE if freezing is a possibility. Remove the CHECK STOPS (4,5) to completely drain the MIXER UNIT (1).

Remove PLASTER GUARD (2) if still installed. Turn on water supplies and check for leaks.

To ﬂush lines, remove the CHECK STOPS (4,5) and run water. If desired, the TEMPERATURE CONTROL UNIT can be removed. Reinstall CHECK STOPS (4,5) and CONTROL UNIT (6), if it was removed.
