Operating Requirements And Important Notes; Service Water Connection (Pressure-Tight) - Atlantic Mileo Serie Manual De Instalación

1. OPERATING REQUIREMENTS AND IMPORTANT NOTES

This appliance is intended only for heating water within enclosed spaces and may be installed only by approved specialists
(in accordance with the relevant norms, such as ÖNORM B2531-1).
The appliance may be used only under the conditions specified on the specification label (such as: ÖNORM H 5195-1).
The tanks are intended for use only under the conditions specified on the specification label.
In addition to the legally recognized national regulations and norms (Austria: ÖVE, ÖNORM, etc.), the connection require-
ments of the local electric and water utility companies as well as the installation and operation manual must be adhered to.
The hot water preparation must conform to the prevailing norms (such as ÖNORM H 5195-1).
The area in which the appliance will be used must be kept above freezing. It must be installed in a location which allows for
access in case of any necessary maintenance, repair or replacement. The costs for any necessary changes to the structural
conditions (e.g. doors and passages too narrow) are not governed by the guarantee and warranty declaration and therefore
shall be rejected on the side of manufacturer. This means that any construction which hinders work on the appliance must be
removed by the customer. When erecting, installing and operating the water heater in unusual locations (e.g., attics, interior
rooms with water-sensitive floors, closets, etc.), provision must be made for possible water leakage and means provided for
catching the water with a corresponding drain to avoid secondary damage. The appliance may be installed and operated
only in the intended configuration and on a horizontal surface which is appropriate for the weight of the tank when it is full
of water. When water with high lime content is used, we recommend installing a commercially available water softener and
operating at a maximum temperature of approx. 65°.

2. SERVICE WATER CONNECTION (PRESSURE-TIGHT)

All water heaters which indicate a rated pressure of 10 bar (formerly: atü or kp/cm²) on the specification label (in Switzerland
6 bar) are pressure-tight tanks and can be plumbed pressure-tight with the corresponding line pressure (in Switzerland 6 bar).
If the line pressure is higher, a pressure reducing valve provided by the user must be installed in the cold water supply
line.
If inappropriate or non-functioning fittings are used, or if the specified operating pressure is exceeded, all guarantees, war-
ranties and product liability for our water heaters are void. Therefore only pressure-rated fittings may be used. Component-
inspected safety devices are to be provided in the cold water supply line according to the connection diagram shown below.
A prototype-inspected safety group to DIN 1988 or ÖNORM B2531-1 for closed water heaters must be installed in the cold
water line.
The water connection may be made only through an inspected membrane safety valve or membrane safety valve combina-
tion fitting (not a piston valve)! A safety valve combination consists of a shut-off, test, non-return, waste and safety valve with
expansion water drain and is installed between the cold water feed line and cold water inlet of the tank in the order shown:
