Series N170-M3 and LFN170-M3

Hot Water Master Tempering Valves

Installation Instructions

Installation should be in accordance with acceptable plumbing prac-

tices. Flush all pipes thoroughly before installation. Installation and field

adjustment are responsibility of the installer and shall be carried out per

following installation instructions.

1. Valves are to be installed as close to building inlet supply as possible

to prevent/minimize pressure fluctuations.

2. Valve body can be installed in multiple positions, see below. Make

sure that the union nuts and tailpieces are tightened securely if you

are using checkstops.

3. Connect inlets and outlet and check for leaks.

4. CAUTION: When N170-M3 or LFN170-M3 supplies tempered

water to self-closing and/or solenoid valves, provide a shock absorb-

er on the discharge line.

5. Before use, check discharge temperature. Reset if necessary

Temperature Adjustment

1. Turn off recirculation pump (if one is in the system).

2. Open enough fixtures to meet the minimum flow requirement of the

valve.

3. Loosen the lock nut. Turn temperature adjustment screw clockwise

to decrease or counterclockwise to increase outlet temperature.

NOTE: Please allow valve temperature to stabilize in before making

your next adjustment. Watts recommends that a temperature gauge is

installed on the tempered line and be checked at least monthly under

normal flow conditions. The gauge must be installed at least 6 ft. away

from the tempering valve.

4. When desired temperature is set, tighten the lock nut. Turn recircu-

lation pump back on. Close open fixtures.

Watts Hot Water Master Tempering Valves cannot be used for

tempering water temperature at fixtures. Severe bodily injury (i.e.,

scalding or chilling) and/or death may result depending upon system

water pressure changes and/or supply water temperature changes.

ASSE standard 1016, 1069 or 1070 listed devices such as Watts

Series MMV, LFMMV, USG, LFUSG, L111 or LFL111 valves should be

used at fixtures to prevent possible injury.

The Watts Hot Water Tempering Valves are designed to be installed at

or near the boiler or water heater. They are not designed to compensate

for system pressure fluctuations and should not be used where ASSE

standard 1016, 1069 or 1070 devices are required. These Watts valves

should never be used to provide “anti-scald” or “anti-chill” service.

Need for Periodic Inspection: Periodic inspection by a licensed

contractor is recommended. Corrosive water conditions, tempera-

tures over 210°F, unauthorized adjustments or repair could render

the valve ineffective for service intended. Regular checking and

cleaning of the valves internal components and checkstops helps

to assure maximum life and proper product function. Frequency of

cleaning depends upon local water conditions.

WARNING

ENGLISH INSTRUCTIONS
