INSTALLATION AND COMMISSIONING MANUAL

Function

Thermostatic mixing valves are used in applications where the user

must be protected from the danger of scalding caused by hot water.

The Caleffi 5213 series provides water at a safe and usable

temperature in situations where the control of the temperature of the

water discharging from a terminal ﬁtting is of the utmost importance,

i.e. within hospitals, schools, nursing homes, etc. The valve is

designed to prevent the flow of water discharging from the mixed

water outlet in the event of the failure of hot or cold supply. The Calefﬁ

5213 series is a high performance combination thermostatic and

pressure balanced mixing valve and is ASSE 1070 listed (temperature

can not exceed 120°F). The valve is complete with check valve at

both hot and cold inlets. Certiﬁed to ASSE 1070 and Low Lead Plumbing

Law by ICC-ES.

CAUTION: If the thermostatic mixing valve is not installed, commissioned and

maintained properly, according to the instructions contained in this

manual, it may not operate correctly and may endanger the user.

CAUTION: Make sure that all the connecting pipework is water tight.

CAUTION: When making the water connections, make sure that the

pipework connecting the thermostatic mixing valve is not mechanically

over-stressed. Over time this could cause breakages, with consequent

water losses which, in turn, could cause harm to property and/or people.

CAUTION: Water temperatures higher than 100°F can be dangerous. During

the installation, commissioning and maintenance of the thermostatic mixing

valve, take the necessary precautions to ensure that such temperatures do

not endanger people.

Leave this manual for the user.

Thermal shutoff

In the event of a failure of either the hot or cold supply, the piston will shut off, stopping water

discharging from the mixed water outlet. The Caleffi 5213 series thermostatic mixing requires a

minimum temperature differential from hot inlet to mixed water outlet of 18°F (10°C) to ensure the

correct operation of the thermal shutoff feature.

Sweat version

Operating principle

The thermostatic mixing valve mixes hot and cold water in such a way as to maintain constant set

temperature of the the mixed water at the outlet. A thermostatic element is fully immersed into the

mixed water. This element then contracts or expands causing movement of the piston, closing

either the hot or cold inlets, regulating the ﬂow rates entering the valve. If there are variations of

temperature or pressure at the inlets, the internal element automatically reacts to restore the original

temperature setting. In the event of a failure of either the hot or cold supply, the piston will shut off,

stopping water discharging from the mixed water outlet.

Use

The Caleffi 5213 series is a thermostatic mixing valve suitable for single or multiple point of

use applications in accordance with installation rules and indications specified in ASSE 1070

standards.

The system must be sized taking into account the current legislation with regard to the nominal

flow rate of each outlet.

1/2”, 3/4”, 1” • Cv= 2 • Kv=1.7 (m3/h)

Flow should never exceed standards for pipe size and materials.

Installation

The following instructions must be read prior to the installation of a Caleffi 5213 series thermostatic mixing

valve. The installer should also be aware of his responsibility and duty of care to ensure that all aspects

of the installation comply with current regulations and legislation.

The Caleffi 5213 series should be installed using the appropriate standard, code of practice and legislation

applicable to each state and following the details in this manual. The Caleffi 5213 series must be installed

by a licensed plumber.

Prior to the installation of the Caleffi 5213 series valve, the system must be checked to ensure that the

system operating conditions fall within the recommended operating range of the valve, i.e.

verify supply temperatures, supply pressures, risk assessments, etc.

The supply system into which the Caleffi 5213 series is to be installed must be thoroughly flushed and

cleaned to remove any debris which may accumulate during the installation. Failure to remove any debris

will affect the performance and the manufacturer’s warranty on the product. In areas that are subject to

high levels of aggressive water, provision must be made to treat the water prior to it entering the valve.

The valve can be installed in any position, whether vertical or horizontal. It is essential that the access to

the valve is not obstructed for future maintenance that may be required to the valve or associated fittings.

It is essential that when the installation is designed and/or installed, all current legislation is noted, e.g. the

maximum distance from the outlet of the valve to any terminal fitting.

The connecting hot and cold water supplies must be connected to the valve strictly in accordance with

the indications on the body of the valve. The inlets of the valves are clearly marked with the letter H (Hot)

and C (Cold). The outlet is marked with the word MIX.

Where one or both the incoming supply pressures are excessive, a Caleffi pressure reducing valve should

be installed to reduce the pressure(s) within the limits.

Any thermostatic mixing valve must be installed with isolating valves, line strainers and check valves at

both the inlets. Isolating valves are required so that the water supply to the valve can be isolated in the

event that servicing is required. Strainers are required to prevent debris from entering the valve. Check

valves are required to both hot and cold inlets to prevent cross-connection.

The Caleffi 5213 series is supplied complete with the check valves at the hot and cold inlets. The check

valve of the sweat version must be dismantled from the tail piece before soldering and then reassembled.

To ensure that the performance of the Caleffi 5213 series valve is maintained (in the event of cold water

failure), the temperature of the hot water supply at the point of entry to the valve must be a minimum of

18°F higher than the set mixed water discharge temperature.

The piping to and from the valve must not be used to support the weight of the valve.

If the valve is not installed correctly, it will not function correctly and may put the user in danger.
