INSTALLATION

IMPORTANT
Mounting must comply with all local codes.
NOTE TO INSTALLER: This product should be installed by a qualified individual, in accordance with local codes and ordinances. It is the responsibility of the installer to properly select, install and adjust these devices as specified in these instructions. For installations that require compliance with Building/Mechanical/Plumbing Codes, the appropriate AM-1 Series valve must be chosen and installed, and the discharge temperature set and locked according to these instructions. AM-1 “C” Series models with the temperature range, 70°F– 120°F (21°C–49°C) and “Standard” models with temperature range 70°F–145°F (21°C–63°C) are ASSE 1017 (point of source application) certified, and CSA ® ®a ® and IAPMOlisted.These models shall be used to supply water to tubs, showers, bathing facilities, and other outlets. These valves should be installed where they will be accessible for cleaning, servicing or adjustment.
ASSE 1017 Applications—Point of Source
These AM-1 Series models can be installed in any position consistent with the intended use. For domestic hot water supply, the valve must be installed as shown in Fig. 1. There shall be no shut-off valves installed between the cold water line and the cold water connection on the AM-1 Series valve. Check valves shall be installed as indicated for NPT  models; all AM-1 model with union fittings are supplied with integral check valves on both the hot and cold ports. A cold water service valve may be installed, as indicated, between the cold water supply line to the distribution system and the cold water line supplying both the water heater and the AM-1 Series valve.

Installation of Union Sweat, CPVC, neon Propress, Push Connect, and PEX Connections
— Union sweat connections, if used, should be soldered prior to assembly to the valve, or without the sealing gasket or optional check valve present. After the joint has cooled,  the sealing gasket and/or check valves may be installed.
— CPVC fittings are limited to a system maximum temperature of 180° F (82° C) and 100psi (689 a).
— PEX fitting and crimp ring (provided by Installer) are designed to meet ASTM F1807 requirements.
— PEX tubing used with PEX fittings must meet ASTM F876 requirements.
— Press connections, using press tools, and installation practices compatible with Viega systems.
— Push connect fittings can be used with both copper and LDPE (plastic). Utilize the included tube liners for non-copper applications.

Installation of Temperature Gauge Adapter

IMPORTANT
Union sweat connections must be soldered before the thermowell with O-ring and sealing gasket are installed. Install the thermowell with O-ring and sealing gasket after the joint has cooled.

1. Install thermowell with O-ring to the thermometer adapter body.
2. Tighten to 75 LB-IN ± 10 LB-IN. DO NOT OVERTIGHTEN.
3. Install the thermometer into the thermowell until seated and tighten the set screw to secure it in place.

VALVE ADJUST CEMENT

To adjust the temperature setting of the mixing valve, attach the mo strip (supplied with the valve) to the piping connected to the Mix port of the valve. Loosen handwheel screw, lift handwheel and turn to the desired temperature as indicated on the most rip. Reposition the handwheel and retighten the screw.
Temperature Setting Procedure
It is possible to limit the temperature range. To use this feature:

M27487A

1. LOOSEN SCREW, LIFT HANDWHEEL.
2. TURN THE HANDWHEEL CLOCKWISE OR COUNTERCLOCKWISE TO ADJUST TEMPERATURE.
3. REPOSITION HANDWHEEL TO LOCK POSITION.
4. RETIGHTEN SCREW.

Thermostrip Installation

Clean pipe and firmly apply Thermostrip on mix outlet of the 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 a water thermometer at the faucet outlet.
The thermostrip is ONE TIME USE ONLY for the initial system temperature setting. Check the expiration date printed on the temperature strip to ensure temperature reading accuracy. If necessary, contact your Resideo distributor to obtain a replacement thermostrip, part number TS205-064.
Thermostrip is only included in models without the temperature gauge.

Post Installation Procedure
1. Write temperature setting on CAUTION label and sign in space provided.
2. Attach CAUTION label to AM-1 valve.
3. Explain the CAUTION label to the owner.
4. Deposit this instruction sheet with the 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.

To clean and/or replace the lower assembly, shut off water and:

1. With a screwdriver, remove the screw and handwheel.
2. Loosen upper nut (do not remove) to allow engaging an adjustable wrench on the 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 the 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 the instructions below or use a new replacement kit assembly. For the correct kit number, see Table 1.

Install spring, diffuser, and lower assembly:

1. Insert spring onto the diffuser.
2. Insert diffuser with spring end first into the body.
3.  Fit valve top assembly into lower assembly and insert into the valve.
4. Tighten lower nut.
5. Reposition the handwheel and insert the screw. Turn the handwheel to the desired temperature setting.
