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.
