1. With a screwdriver remove screw and hand wheel.

2. Unscrew lower nut (counterclockwise). This removes top 

assembly.

3. Brass assembly will pop up. Remove lower assembly, 

diffuser and spring.

4. Carefully remove any scaling (calcium deposits) or 

foreign particles from valve seat and other internal parts. 

Use vinegar to remove calcium. Soak parts until calcium 

becomes soft and can be scrubbed and washed off.

5. Replace cleaned spring, diffuser and lower assembly 

following instructions below or use new replacement kit 

assembly.

A. Insert spring onto diffuser.

B. Insert diffuser with spring end first into body.

C. Fit valve top assembly into lower assembly and 

insert into valve. Tighten lower nut. Line up arrow on 

handwheel Stop with raised arrow on body and hold 

while tightening upper nut.

D. Place handwheel on valve.

E. Turn handwheel to desired temperature setting and 

insert screw.

Thermostatic Mixing Valve certified to ASSE 1017, ASSE 1070 

and CSA approved. Temperature Setting Range (as required, 

see page one), Maximum Pressure rating of 125 psi (862 kPa), 

maximum Hot inlet temperature of 212° F (100° C), Nickel 

plated Brass/Bronze Construction, Teflon coated valve body 

wear surface, Teflon coated brass shuttle, EPDM O-rings, 

Proportional design (simultaneous control of hot and cold 

ports), with either sweat union, NPT (female) union or NPT 

(female) connections. Valve for domestic hot water 

applications shall have temperature lock. Design shall be 

straight thru, with hot and cold ports at the same level. The 

design shall permit easy access for maintenance, with 

replaceable thermostatic element.

The AM-1 Series valves are “in-line” plumbing components 

(NSF 61 Section 8) in the context of ANSI/NSF 61, Drinking 

Water System Components - Health Effects. They are not end 

point devices (NSF 61 Section 9). They are all made of various 

metals, none of which exceeds 8% lead content, which is the 

limit imposed by NSF 61 for lead content. They all therefore 

comply with the Safe Drinking Water Act of 1974, as amended 

in 1996. Lead free models contain less than .25% lead which 

complies with lead free codes.
