TECHNICAL CHARACTERISTICS
The storage tanks for technical water have been designed for residential applications for stabilising the
primary circuit. They are set up to operate in conjunction with our Vitocal 100-A heat pumps which can be
properly mounted on the unit thanks to the appropriate fasteners. Isolation from vibrations is assured by the
supplied anti-vibration supports to be installed between the storage tank and the heat pump. All water tanks
are properly insulated with thermal insulation material with a thickness of 50mm.
There are also: the connections to insert any expansion vessel, which can be easily installed inside the
structure without the need for additional spaces, and connections to add an electric heater for technical
water heating. In addition, each model is supplied with a charge/discharge valve for easier maintenance and
cleaning operations.

FRAMEWORK
All the external panels of ACT units are made up of hot-galvanised sheet metal; most of them are painted
with polyurethane powder enamels at 180°C. The frame is self-supporting with two removable panels for
easier inspection, maintenance of the inner parts and of any installed kits. All screws and rivets for outdoor
installation are in galvanised steel.
The colour of ACT units is the same as the painting of Vitocal 100-A units.

STORAGE TANK
The water tanks are made of steel coated with insulation material 50mm thick, in order to get high efficiency
to maintain the temperature of the stored technical water.
5.3
CONNECTION JOINT BETWEEN ACT AND Vitocal 100-A UNITS
An extendable-flexible fitting is provided for the connection between the
water tank and the heat pump which should be mounted on top of the
storage tank. Use the supplied appropriate elbow fitting for the
connection between ACT unit and the extendable pipe. In addition it is
recommended to insulate the pipe with suitable protective material.
For any other type of connection, it is recommended to use a flexible
pipe in order to avoid vibrations between the two units. See Chapter 0
for the installation references.
