4 Description of the product
4.1 General description
The EL 110 SL domestic hot water tank comes ready for connection to a
condensing or non-condensing oil boiler.
EL 110 SL domestic hot water tanks can be connected to boilers used for
heating domestic hot water.
Main components:
The tank is made of high quality steel and is lined with food safe quality
enamel vitrified at 850°C, which protects the tank from corrosion.
The tank is protected against corrosion by a magnesium anode.
The coil-shaped heat exchanger welded into the tank is made of smooth
piping, its external surface, which comes into contact with drinking wa
ter, being enamelled.
The appliance is insulated by CFC-free (chlorofluorocarbon-free) polyur
ethane foam, which helps to reduce heat losses to a minimum.
The outside casing is made of painted steel sheets.
This domestic hot water tank is offered exclusively as a package with the
products listed in the table below and cannot be used as an independent
tank.
Note
The energy labels, product fiches and technical specifications per
taining to product packages are available on our internet site.

5 Before installation
5.1 Regulations governing installation
Note
The installation must comply on all points with prevailing regula
tions and directives, which govern work and interventions in indi
vidual homes, blocks of flats and other buildings.
Note
Only qualified professionals are permitted to install the domestic
hot water tank, in accordance with prevailing local and national
regulations.
Caution
In compliance with the safety rules, fit a sealed safety valve to the
domestic cold water tank inlet on the domestic hot water tank.
Caution
The components used for the connection to the cold water supply
must comply with the prevailing standards and regulations in the
country concerned.
5.2 Installation requirements
5.2.1 Water operating pressure
The tanks on our domestic hot water heaters can run at a maximum oper
ating pressure of 1.0 MPa (10 bar). The recommended operating pressure
is under 0.7 MPa (7 bar).
5.2.2 Domestic water quality
In regions where the water is very hard (Th > 20°f), we recommend fitting
a softener.
The water hardness must always be between 12°f and 20°f to be capable
of providing effective protection against corrosion.
The softener does not bring about a derogation from our warranty provi
ded that it is approved and set pursuant to the codes of practice and the
recommendations given in the instructions for the softener and is regularly
inspected and maintained.
