OPERATION IN ACCORDANCE

WITH INSTRUCTIONS

Our domestic hot water tanks are

designed and manufactured exclusively

for there-heating and storage of domestic

hotwater.

The domestic hot water heaters must only

be heated using heated water in a closed

circuit.

The tank is equipped with an electric

element of 2200 W controlled by the

thermostat of the Comfort E.

INSTALLATION

POSITION

The hot water cylinder must be installed in an area that is dry and protected from the elements.

Choose the most suitable location according to the position of the boiler and distance

tothedomestic hot water supply, in order to reduce temperature and pressure drops within the

pipe work.

The appliance should be positioned to allow the replacement of the sparge tube and

dry well during servicing, if required.

The Comfort E must be assembled with the heating electrical heating element to the

bottom (DHW pipes to the bottom).

INSTALLATION

HYDRAULIC CONNECTION

The installation of a safety unit

iscompulsory.

To avoid water discharge on to the

tank, the safety unit must never

be installed above the tank.

In certain countries the domestic

kits must be approved and

included a temperature and

pressure relief valve fitted in the

hot outlet.

To avoid any risk of corrosion,

connect the stainless steel tank

directly to the earth.

Hot water can burn!

ACV recommends using

apreset thermostatic mixer

valve in order to provide hot

water at a maximum of 60°C.

Recommendations

• The tank’s cold water supply pipe must

be fitted with a safety unit that includes

at least: an isolating valve, anon-return

valve, a domestic safety valve calibrated

to 7 bar and an expansion vessel of

suitable size.

• When the operating pressure exceeds

6 bar, a pressure reducer (2) must be

installed before the safety unit.

• Union fittings are recommended

for the easy dismantling of the DHW

connections. Ideally, the “dielectric”

version is favourable to protect

theconnections from corrosion with

the presence of different metals such

ascopper and galvanised steel.

• The installation of a domestic expansion

vessel avoids discharge from the safety

valve (loss of water).

• Capacity of domestic water vessels:

5 Litres for the models : 100 / 130

8 Litres for the models : 160 / 210

12 Litres for the model : 240

Refer to the manufacturer’s

technical instructions on the

expansion vessel for more details.
