THERMOSTATIC MIXING VALVES

Installation Guide

Application

Legend thermostatic mixing valves are designed for applications requiring temperature control, scald

prevention and reduction of thermal shock in domestic potable water distribution (ModelT-45NL)

and radiant heating installations (ModelT-46NL). The three-way thermostatic mixing design permits

controlled water temperatures to individual or multiple ﬁxtures, gang showers or hydronic heating loops.

Before beginning, check your local code requirements. Select the correct model for your application, as it

pertains to at-the-source, individual or multiple ﬁxtures, point-of-use or heating systems applications:

Model T-45NL: Certiﬁed in compliance with ASSE 1017, 1069, 1070, and ANSI/NSF 61

Model T-46NL: Certiﬁed in compliance with ASSE 1017 and ANSI/NSF 61

CAUTION!

PLEASE READ THESE INSTRUCTIONS BEFORE INSTALLING AND OPERATING!

Note: Both models feature optional union-connection types in MNPT, compression, press-t, push-t, PEX barb (F 1807), and sweat:

THERMOSTATIC MIXING VALVES

Installation Guide

Applications

1. Valves must be installed in an accessible location, to permit adjustment, servicing and cleaning procedures. It is strongly recommended

that ball valves are installed upstream of the hot and cold inlet connections, to allow for the removal and servicing of the mixing valve:

Installation Guide

Installation

1. Select the correct connection types to be used, at each of the three connections: HOT inlet, COLD inlet

and MIX outlet.Verify that the line lengths are correct, to permit union attachment of the valve’s body

to each connection:

2. Install the union nuts onto the tubing or pipe ﬁrst, in the correct orientation. For copper

press and PEX crimp (F 1807) connections, install onto the tubing in accordance with the tool

manufacturer’s instructions. For threaded pipe, copper tubing sweat, compression and Insta-Loc II™

push-ﬁt connections, apply the correct industry installation practice.

Note: Insta-Loc II™ push-t connections’ insertion depths are as follows: ½” tubing: 15/16” ¾” tubing: 1-1/8”.

3. Verify that the union gaskets are in-place and install the body onto the three union connections.

Tighten the union nuts ﬁrmly.

4. Pressurize the system and check for leaks. Leakage at a union connection may occur if the union

nut is over-tightened.

Adjustment: T-45NL

All adjustments should be performed by a licensed, qualiﬁed contractor. Adjustments

must be made while the valve is pressurized.

1. Using the forked tool (included) pry upward, at the base of the setting knob until the brass bonnet is

exposed: (See photos A & B)

2. Turn the knob CLOCKWISE to INCREASE the cold water ﬂow to the mixed outlet, LOWERING the

delivered water temperature.Turn the knob COUNTER-CLOCKWISE to INCREASE the hot water

ﬂow to the mixed outlet, RAISING the delivered water temperature. (See photo C)

3. Using a thermometer placed in the water ﬂow, verify the mixed water temperature. Adjust the knob

until the desired temperature is reached.The factory pre-set temperature is 107.6°F

4. Lock the setting by pushing the setting knob downward until it seats.Verify that the knob is locked

into place by attempting to turn it. It should not rotate. (See photo D)

Installation Guide

Adjustment: T-46NL

All adjustments should be performed by a licensed, qualiﬁed contractor. Adjustments

must be made while the valve is pressurized.

1. Using a Phillips-head screwdriver, loosen and remove the screw at the top center of the setting knob.

Remove the setting knob. (See photo E)

2. Using a 21 MM wrench or adjustable wrench, loosen the stem locknut by turning it counter-

clockwise at least one complete revolution. (See photo F)

3. Using a 12 MM socket and ratchet, turn the stem CLOCKWISE to INCREASE the cold water ﬂow to

the mixed outlet, LOWERING the delivered water temperature.

Turn the stem COUNTER-CLOCKWISE to INCREASE the hot water ﬂow to the mixed outlet,

RAISING the delivered water temperature. (See photo G)

4. Using a thermometer placed in the water ﬂow, verify the mixed water temperature. Adjust the stem

until the desired temperature is reached.The factory pre-set temperature is 107.6°F

5. Lock the setting by turning the 21 MM stem locknut clockwise, until it’s tightened against the bonnet.

6. Replace the setting knob. Tighten the screw.

Installation Guide

Operation

When properly installed, under the correct operating parameters and properly adjusted, both models

will operate automatically.

The correct operating parameters must be present:

Factory pre-set: 107.6°F

T-45NL

Temperature adjustment range: 86°F to 120°F

Cold water supply temperature range: 41°F to 68°F

Hot water supply temperature range: 132.8°F to 149°F

Accuracy of mixed water temperature: +/- 3.8°F

Minimum temperature diﬀerential between hot supply and MIX outlet: 21.6°F

Supply pressure: Static: 145 psi

Dynamic: 72.5 psi

Maximum allowable imbalance: 2:1 ratio

Minimum ﬂow rate: 0.5 gpm @ 0.8 psi (see note A)

Maximum ﬂow rate: 15 gpm @ 125 psi (see note A)

T-46NL

Temperature adjustment range: 86°F to 130°F

Cold water supply temperature range: 41°F to 68°F

Hot water supply temperature range: 132.8°F to 149°F

Accuracy of mixed water temperature: +/- 3.8°F

Minimum temperature diﬀerential between hot supply and MIX outlet: 21.6°F

Supply pressure: Static: 145 psi

Dynamic: 72.5 psi

Maximum allowable imbalance: 2:1 ratio

Minimum ﬂow rate: 0.5 gpm @ 0.8 psi (see note A)

Maximum ﬂow rate: 15 gpm @ 125 psi (see note A)

Note A: Should not be used for valve selection or system sizing. The Cv valve listed on the product

submittal sheet should be used for valve selection.

Maintenance

Annually inspect the unit for any leakage. Correct as necessary. Annually check the mixed temperature

supply. Over time, performance could diminish due to hard water conditions or pipe scale causing

binding of the internal piston. Shut oﬀ the water supply and remove the unit by loosening and detaching

the union ends. Inspect the internal waterways. If they’re clogged with debris, it is likely that the unit’s

piston is binding. Immersion and soaking of the unit in the appropriate de-scaling formula should

restore function. DO NOT DISASSEMBLE the unit! If after soaking the unit continues to malfunction,

REPLACE the entire unit.
