4. To limit the low temperature range at a set minimum (higher than
pos. 1 to pos. 4): Place arrow on handwheel as closely as possible
to the right of the L-slot bracket (facing arrow) (see Fig. 2).
5. SAFETY CHECK: To make sure above procedure has been
followed correctly, ascertain that actual mixed temperatures
maximum or minimum are set at the desired limit.
NOTE: After adjusting for limited temperature, handwheel position
numbers no longer agree with Table 1.

Thermostrip Installation

Clean pipe and firmly apply Thermostrip on mix outlet of valve. Flow
water and adjust mixed outlet temperature for desired setting range.
Actual mixed water temperature is indicated in green with 2° F (1° C)
increments. Blue means slightly lower and brown means slightly higher.
WARNING
Water Temperature above 120°F (49° C) can cause serious
injury. Mixing valve temperature setting should be done
by licensed contractor per local code requirement. To
ensure correct temperature control, use water
thermometer at faucet outlet.
The thermal temperature indicator strip is ONE TIME USE ONLY for initial
system temperature setting. Check date code printed on temperature
strip to ensure temperature reading accuracy.

Post Installation Procedure

1. Write handwheel setting on CAUTION label and sign in space
provided.
2. Attach CAUTION label to AM-1 valve.
3. Explain CAUTION label to owner.
4. Deposit this instruction sheet with owner.
OPERATION
The AM-1 series valve provides for automatic operation through the use
of a thermostatic element in the product. The element will control the
mixing of the hot and cold supply to provide mixed tempered water to
connected fixtures. This provides constant water temperature under
different working conditions.

MAINTENANCE PROCEDURES

Hard water conditions may result in scale deposits, causing binding of
internal parts in extreme cases. Cleaning the internal parts will usually
restore the valve to proper operating conditions. In some cases, it may be
necessary to replace the lower assembly.
NOTE: Field Calibration of AM-1 Series Valves when testing apparatus is not available.

To clean and/or replace the lower assembly, shut off water and:
1. Pierce center circle of nameplate with a screwdriver and remove
screw and handwheel.
2. Loosen upper nut (do not remove) to allow engaging an adjustable
wrench on lower nut. Unscrew lower nut (counterclockwise). This
removes top assembly.
3. Brass top assembly will pop up. Remove lower assembly, diffuser
and spring.
4. Carefully remove any scaling (calcium deposit) 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. Do not use solvents or scratch metallic /

Teflon coated surfaces.
5. Replace cleaned spring, diffuser and lower assembly following
instructions below or use new replacement kit assembly. For
correct kit number, see Table 2 below.
Install spring, diffuser and lower 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.
D. Tighten lower nut. Line up arrow on Handwheel Stop with raised
arrow on body and hold while tightening upper nut.
E. Turn plastic star wheel clockwise until it stops, then back as shown
in Table 2.
F. Place handwheel on position 1 over raised arrow and insert screw.
Turn handwheel to desired temperature setting.
