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 thermostrip is ONE TIME USE ONLY for initial system
temperature setting. Check expiration date printed on
temperature strip to ensure temperature reading
accuracy. If necessary, contact your Honeywell distributor
to obtain a replacement thermostrip, part number TS205-
064.
Thermostrip only included in models without the
temperature gauge.

Post Installation Procedure

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.
To clean and/or replace the lower assembly, shut off water
and:
1.
With a screwdriver, 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 1.
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.
E.
Reposition handwheel and insert screw. Turn handwheel to
desired temperature setting.
