Harrington Brass Works Installation Information for Thermostatic Mixer with 1 Shut Off 00-386NR-000 Servicing & Maintaining the Temp. Cartridge Sedimentation in the water will clog the filter screens around the cartridge. This is also true especially in new installations. To maintain and clean the mixer cartridge, follow the instructions below: 1 Shut off water supply on the main water inlets, or the integral stop/check valves on both inlets . 2 R emove the temperature handle assembly Å - É by using a hex wrench and removing the set hex set screw Ç and the temperature limit stop Ñ. 3 U nscrew the cartridge using adjustable wrench with smooth flat jaws. Rinse the strainers around the cartridge under running water or leave to soak in vinegar or de-scaling agent. 4 Before re-assembling cartridge, clean its housing with wet cloth and lubricate the o-rings around the cartridge. 5 Re-assemble cartridge into body. 6 Replace the stepped plastic temperature limit washer Ñ according to the drawing and turn spindle A until you reach required temperature 100.4ºF (38ºC). 7 R eplace the temperature control handle. Before You Begin Hot Water Supply Temperature . Maximum inlet hot water temperature is 185ºF (85ºC) and the minimum inlet cold water temperature is 41ºF (5ºC). The recommended hot water inlet temperature is 149ºF (65ºC). The minimum temperature difference between the hot inlet water temperature and the mixed tempered water temperature is 50ºF (10ºC). B A Operating pressure . The recommended maximum inlet water pressure is 75 PSI (5 bar). Minimum water inlet pressure is 1.5 PSI (0.1 bar). Piping should installed properly to maintain a balance between Hot and Cold inlet operating pressure to maintain maximum efficiency and consistent mixed water temperature. When water pressure exceed 75 PSI, a pressure reducing valve needs to installed upstream of the mixer.

The mixer is furnished with a maximum temperature limit stop set at 10 9.4ºF (43ºC). Mixer inlet and outlet ports are ¾” NPT. The bottom outlet may be used for a bath spout or plugged with a standard ¾” NPT pipe plug. A separate shut off valve must be used in conjunction to control on/off function and flow control. A temperature variation will occur if water is dually supplied by both the top and bottom port at the same time. Plumbing recommendations · Large runs of pipe work will cause frictional loss of pressure. · Flush all piping thoroughly before installing the valves to prevent clogging of filter screens. · Ensure adequate supply of both hot and cold water can be maintained. building code compliance. The mixing valve complies with ANSI/NSF61 standard and should be installed in compliance of local building codes. Before Removing the Cartridge Screw the 2 threads of non-return valve before removing the cartridge (see drawing). In case of reduction of flow rate, close the two main inlets and check if the filter at the bottom of the non-return valves are dirty, in this case clean them. Servicing & Maint. Integral Stop/Check Valves otating the 2 screws on the stop/checks will shut off the water to the cartridge R for service and maintenance. If you are experiencing a reduction of water flow to the mixer, you may have an obstruction of debris in the check valve or in the strainer at the bottom. Shut off the water for both the hot and cold at the main inlet; remove the stop/check assembly. Clear the strainer and check valve of any debris and replace back into the inlets. This should be done before removing or servicing the cartridge. Be certain to fully open the integral stop after service. 00-386NR-000 Installation Information for Thermostatic Mixer (Less Valve) Specifications 3/4 NPT 6” / 150mm 3.125” / 80mm 3/4 NPT 3/4 NPT 1.125” 28mm 3/4 NPT 4.75” / 120 mm Exploded Parts Diagram 0.75” 20mm Wall Specifications NPT 3/4" 3.25" / 80mm 2.25" / 57mm NPT 3/4" 3" / 75mm 6" / 151mm 9.25" / 235mm P000000114 Valve Holder with closure 0 - 0.75” 2”-2.8” P000000005 Chromed ring Ø2” with O-Ring P000000105 Thermostatic 6.25" / 160mm cartridge with stop ring 5.5” / 138mm 6.125” / 156mm Care/Cleaning of Your Product After installation, the finished trim portion should be maintained by wiping with a soft, damp, clean cloth and then polished with a dry dust cloth. Never use abrasive cleansers or detergents. Cleaners containing alcohol, acid or corrosive chemicals should not be used. Some household bleaches and denture cleaners can damage the finished pieces, and if splashed onto the trim, it should be immediately washed off with cold water. 4.75” / 120mm If these instructions are followed, the fitting will give many years of satisfactory use. There is a policy of continuous improvement and the manufacturer reserves the right to change specification without notice.
