DESCRIPTION OF FUNCTION
“Tank-in-Tank”system
“Tank-in-Tank” is a heat exchanger with a built-in accumulator, made
up of two concentric tanks: the inner tank contains domestic water
to be reheated (secondary) and the outer tank contains the heating
fluid (primary) which circulates between the two tanks and transfers
its heat to the domestic water.
DomesticHotWatercylinder
The inner tank is the heart of the tank: it is subject to the
aggressiveness of the supply water, to high pressures and to
variations in temperature. This tank is made of solid chrome-
nickel stainless steel (stainless steel 304 or duplex), fully welded
under argon protection using the Tungsten Inert Gas (T.I.G.)
technique.
Before assembly, the convex bottoms are pickled and passivated in
order to improve the tank’s lifespan and in particular its resistance to
corrosion. The shell is corrugated all the way up using an exclusive
manufacturing process. This design gives considerable resistance to
pressure and limits the adherence of lime scale by allowing the tank
to expand and contract.
Outertank
The outer tank containing water from the primary circuit arriving
from the boiler, is made of carbon steel STW 22.
ThermalInsulation
This is carried out using high density injected polyurethane
foam, 50 mm containing no CFCs.
Lining
The tank is covered using polypropylene, a plastic material
which offers a high resistance to shocks and which is also very
pleasing to the eye.
OptionalheatingelementforSLE
The SLE tanks can be installed with a self- controlled heating
element with built-in control and safety thermostats.
The control thermostat of the tank can not control the heating
element.
INTRoDuCTIoN
DESCRIPTION OF OPERATION
Operatingcycle
The thermostat is triggered and starts up the pump which circulates
the heating water. This water circulates around the inside tank and
heats up the domestic water. When the required temperature is
reached, the thermostat stops the primary circulating pump.

Recommendations
• The pipe feeding the tank with cold water must be fitted with
a safety unit comprising at least the following:
- An isolating valve [1]
- a non-return valve [3]
- a safety valve [5]: (set to < 10 bar)
- a sanitary expansion vessel of appropriate dimensions.
• When the operating pressure exceeds 6 bar a pressure
reducer [2] must be installed before the safety unit.
• Union fittings are recommended for easy removal of the
connections. Ideally the “dielectric” version is preferable
in order to protect the connections against corrosion in
the presence of dissimilar metals such as copper and
galvanised steel.
• The installation of an expansion vessel avoids safety valve
runoff (loss of water).
• Domestic hot water expansion vessel capacity:
8 Litres: for the following models: 130 / 160
12 Litres: for the following models: 210 / 240 / 300
Please see the technical instruction manual of the

WHAT TO CHECK START-UP?
• Safety valves (domestic hot water) and (central heating)
correctly installed and discharge connected to the drains.
• Domestic hot water tank and primary circuit filled with
water.
• Air bleed correctly carried out on both circuits.
• Air valve sealed.
• Both hot and cold water pipes correctly connected to the
tank’s hot water circuit.
• Heating feed and return correctly connected to the tank.
• The electrical cabling is correct.
• The tank’s thermostat is set according to the instructions
shown in § “Setting the thermostat”.
• Connections checked and free of leaks.
SETTING THE THERMOSTAT
Factorysettings
The thermostat of the tank is factory preset to the minimum
recommended by the standards, over a range of settings from
60 to 90°C.
To increase the temperature: turn the button clockwise.
To reduce the temperature: turn the button anticlockwise.
When adjusting the tank’s thermostat, make sure that the
boiler temperature is set to a value at last 10°C higher than
tank’s thermostat.
Recommendations

• The water heated to wash clothes, dishes and for other
purposes can burn and cause serious injury.
• Children, the elderly, the sick or the disabled are the most at
risk from burns due to very hot water. Never leave them on
their own in a bath or under the shower. Never allow young
children to turn on hot water taps or fill their own baths.
• Set the water temperature appropriately according to the
intended use and plumbing codes.

3. Bleed the air in the circuit by opening the air vent located on
the upper part of the tank.
4. Follow the instructions supplied with the boiler for filling.
5. When the tank is full and the air has been removed, the
bleed valve should be closed.
 Ensurethatthebleedvalveisproperlysealed.
6. If any antifreeze is needed in the primary circuit it mus be
compatible with Public hygiene rules and not be toxic.
A food-type Propylene Glycol is recommended.
Consult the manufacturer to ensure that the antifreeze is
compatible with the tank’s construction materials.

3. Open the drain valve [4] and drain the hot water off.
4. To speed up the process, open the air vent located on the
upper part of the tank.
5. When the emptying is finished, close the drain cock again
then screw the air valve up again.
PERIODICAL CHECKS BY THE USER
• Check the pressure of the boiler’s pressure gauge: it should
be between 0.5 and 1.5 bar.
• Carry out a monthly visual inspection of the valves,
connections and accessories in order to detect any leaks
or malfunctions.
• Periodically check the air valve located on the upper part of
the tank to make sure that it is not leaking.
• If you notice anything unusual, contact a technician or your
heating engineer.
ANNUAL SERVICE
The annual service, carried out by a technician, must include
the following:
• Checking the air valve:
The air bleed can lead to water being added to the system.
Check the pressure on the boiler’s pressure gauge.
• Manually activate the domestic hot water safety valve once
a year. This operation will lead to a discharge of hot water.
 Beforedrawinganyhotwaterthroughthesafetyunit,
makesurethatthedischargegoesdirectlytothedrain
inordertoavoidanyriskofburningordamage.
• The discharge pipe should be open to the atmosphere.
• If the safety unit occasionally “drips” this may be due to an
expansion problem or to clogging of the valve.
• Follow the circulator’s maintenance instructions.
• Check that the valves, cocks, controllers and any electrical
accessories installed are working properly (see the
manufacturer’s instructions if necessary).
