Pre-adjustable filling units

Function

Product Range

The automatic ﬁlling valve is a device consisting of a pressure reducing valve with compensating seat, visual system pressure setting indicator, an inlet ﬁlter, anti-scale internal parts, a shut-off valve and a check valve.

It is installed on the water inlet piping in sealed heating systems, and its main function is to maintain the pressure of the system stable at a set value, automatically ﬁlling up with water as required.

This valve has been designed as pre-adjustable, which means that it can be adjusted at the required pressure value before the system charging phase.

After installation, during the ﬁlling or topping-off phase, the water feed will stop when the set pressure is reached ﬁlling 50% faster than other valves. There are no levers to ﬂip or valve to close.

Pre-assembled with the 573 series backﬂow preventer, the AutoFill™ Combo features an atmospheric vent which is designed to protect drinking water systems from return ﬂow, caused by back-siphoning or back pressure, of contaminated ﬂuids. The 573 series has been speciﬁcally certiﬁed to standards CSA B64.3 and ASSE 1012.

These items are designed for use in closed hydronic systems. Do not use in plumbing applications. These items do not meet the low-lead plumbing standards of U.S. and Canada.

SAFETY INSTRUCTION

This safety alert symbol will be used in this manual to draw attention to safety related instructions. When used, the safety alert symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS

INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD.

WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

CAUTION: All work must be performed by qualified personnel trained in the proper application, installation, and maintenance of systems in accordance with all applicable codes and ordinances.

CAUTION: If the automatic filling unit is not installed, commissioned and maintained properly, according to the instruction contained in the manual, it may not operate correctly and may endanger the user.

CAUTION: Make sure that all the connecting pipework is water tight.

CAUTION: When making the water connections, make sure that the unit

connecting pipework is not mechanically over-stressed. Over time this could cause breakages, with consequent water losses which, in turn, could cause harm to property and/or people.

CAUTION: In the case of highly aggressive water, arrangements must be made to treat the water before it enters the unit, in accordance with current legistion. Otherwise the unit may be damaged and will not operate correctly.

Removable filter cartidge

Installation

The cartridge containing the operating mechanisms, protected by a large surface area strainer, is removable. This makes it very easy and quick to carry out inspections, internal cleaning and even replacement of the cartridge itself. Water intake is proportional to the air vented from the system.

1. Filling unit can be installed in either horizontal or vertical position. It is, however, vital that the unit is not installed upside down.

2. The special method of mechanical pre-adjustment with pressure setting indicator makes it possible to set the unit to the required value in the system before the beginning of the filling phase.

3. The unit is normally set at a pressure not less than that obtained by adding the hydrostatic pressure and 4 psi (0,3 bar).

4. During filling, the internal mechanism will automatically regulate the pressure until it reaches the required value, without the need to oversee the filling operation itself. This prevents the system being charged to a higher pressure than required.

5. Given the pre-calibrating function, the presence of the downstream pressure gauge is not essential.

6. When the system is filled, the shut-off valve can be closed. In order to restore the automatic topping-off condition, merely re-open the valve. The pressure in the system will gradually return to the set pressure.
