Ed. 04/2012
Robur is not liable for ensuring that water quality is always compliant with what reported in
Table 20 is not’s. Non-compliance with indications above may jeopardize the proper
operation, integrity and reliability of Robur appliances, invalidating the warranty.
For any further detail, please contact directly Robur S.p.A. (tel.+39 035.888.111).
Examples of typical water system layouts with the required components for the ACF can
be seen in Figure 15, Figure 14 and Figure 16 starting on page 46; which are:
FLEXIBLE CONNECTORS for the ACF water and gas connections;
PRESSURE GAUGES installed on the delivery and return tubing;
FLOW CONTROL VALVE, balanced slide valves or intermediate slide valves can be
used;
WATER FILTER installed on the ACF return tubing;
BALL VALVES for the blocking of the water and gas piping of the appliance;
WATER SYSTEM CIRCULATION PUMP, connected to the water return piping for the
pumping of water to the ACF (see “ACCESSORIES”, page 81 for the pump, and Figure 14
on page 45 for the plant diagram), chosen for the characteristics of the plant;
SAFETY VALVE - 3 bar (eventual);
PLANT FILLING system. If an automatic filling system is used, the percentage of
monoethylene glycol in the plant should be checked every season.
DRAIN VALVE (approximately ؽ”) to be installed on the piping to facilitate emptying
when necessary;
Devices for the RELEASE OF AIR in the tubes.
EXPANSION VESSEL of appropriate volume for the requirements of the plant.
The ACF60-00 is not equipped with an expansion vessel: it must therefore be
installed on the plant by a plumber. The size of the expansion vessel (closed type)
should be suitable for the maximum temperature range and the maximum
operational water pressure of the plant.
A suitable temperature control system must be installed on the ACF60-00, which acts as a
control switch.
A Direct Digital Controlleris available as an accessory, see SECTION 6, page 81
There must ALWAYS be a constant circulation of water inside the ACF chillers: so
that the required flow of water is constant and always guaranteed, both while
running and during shutdown periods. If the water pump is directly connected to the
electronic circuit board (clean contact N.O. CIRC), the pump must continue the
circulation of water for an additional 7 minutes after shutdown of the ACF.
