Instructions for Use

General Information.

VAREM fixed or interchangeable membrane expansion tanks and/or pressure tanks are manufactured with respect to the essential safety requirements of the European Directive 97/23/CE. These instructions are drawn up in compliance and in relation to article 3.4— attachment 1 to said Directive 97/23/CE and are attached to the products.

Description and product use.

Heating: the AQUAFILL expansion tank is necessary in order to absorb the volume increase of the water due to its thermal expansion caused by the rise in temperature, therefore limiting the pressure increase in the plant.
AQUAFIT pressure tank with the membrane is a component necessary for the long-lasting and regular operation of the drinking water distribution and pumping plants, constituting a reserve of pressurized water and therefore limiting pump interventions.
All of the tanks and/or pressure tanks are designed for use with group 2 fluids; any other type of fluid is not accepted (unless declared specifically in writing by Va re m Spa).
The AQUAFILL expansion tanks and pressure tanks are made up of a closed metal container fitted with an internal membrane. The AQUAFILL membranes have a balloon-like conformation with attachment to the flange, which prevents direct contact of the water with the metal sides of the tank

Technical Features.

The technical features of the expansion tank and/or the pressure tanks are given on the plate applied to each individual product. The data shown is Code, Serial NG., Date of manufacture, Capacity, Operating temperature (TS), Pre-charge, MAX operating pressure (PS). The label is applied to the VAREM expansion tank and/or the pressure tank and must not be removed or its contents modified. The product must be used in compliance with the technical features stated on the label by Varem Spa and the limits prescribed cannot be violated for any reason.

Installation.

Correct dimensioning of the tank with respect to its use; an incorrectly dimensioned tank and/or pressure tank can cause damage/injury to objects/persons. Dimensioning must be performed by specialized technicians.
Correct installation performed by specialized technicians in compliance with current national Standards, respecting the prescribed tightening torque values of the fitting (fig. 1) and the assembly suggestions (fig. 2). In the event of several tanks in series or parallel, they must be connected at the same height. If tanks with volumes over 12 I are mounted with fitting upwards, suitable support is necessary (fig. 3); do not install the tank cantilevered if it is not supported (fig. 4).
The heating tank must be installed in proximity to the boiler and connected to the return or backflow piping (fig. 5)
The pressure tank must be positioned in pump flow (fig. 6).
A safety valve must be present in the plant, with pressure calibration lower than or equal to the maximum pressure of the tank and/or pressure tank; the absence of the safety valve with the max operating pressure exceeded can cause serious injury/damage to persons, animals, and objects.
Initial pre-charge pressure stated on the label and for standard applications; can be regulated 0.2 bar lower than the pressure switch start setting; within the range ±20%. The pre-charge must be controlled (with calibrated manometer applied to the valve) before product installation.
Prevent corrosion of the painted tank by not exposing it to aggressive environments. Make sure that the tank does not constitute a conductive part and that there are no stray currents in the plant in order to prevent the risk of tank corrosion.

Maintenance.

Maintenance and/or replacement must be performed by specialized and authorized technicians in compliance with current national standards, making sure that:
All plant electrical equipment is not live
The expansion tank has cooled down sufficiently
The expansion tank and/or pressure tank are completely drained of water and the air pressure is discharged before performing any operations on the same. The presence of pre-charge air is very dangerous for the projection of pieces, which can cause serious injury/damage to persons, animals,s, and objects. The presence of water in the tank increases its weight greatly.
Periodic checks

Pre-charge: once a year check that the pre-charge pressure is indicated on the label, with a tolerance of +/-20%. IMPORTANT: To perform the operation the water must be emptied completely from the tank (empty tanks).
If the tank and/or pressure tank is discharged, the pre-charge value must be taken to that indicated on the label.
Once a year, visually check the lack of corrosion on the tank. The tank MUST be replaced in the event of corrosion.

Safety precautions for residual risks.

Failure to comply with the following provisions can cause lethal wounds, damage to objects and property, and make the tank unusable. The pre-charge pressure must be regulated within the range of 0.5-3.5 bar; the initial value is for standard applications. It is prohibited to drill and weld the expansion tank and/or pressure tank with flame. The expansion tank and/or pressure tank must never be uninstalled when in work conditions. Do not exceed the maximum operating temperature and/or maximum pressure accepted. It is prohibited to use the expansion tank and/or pressure tank differently than its declared use. Every VAREM expansion tank and/or pressure tank is tested, controlled, and packaged before being dispatched. The manufacturer is not liable for any damage caused by incorrect transport and/or handling if the most suitable means are not used, which guarantees the integrity of the products and the safety of persons. VAREM DOES NOT accept any type of responsibility for damage/injury to objects/persons deriving from dimensioning, incorrect use, installation, or improper use of the product or of the integrated system. Do not use the heating ranges for sanitary use.
