Figure 3: Assembly Position - DAB EVOSTA2 OEM Installationsanweisung Und Wartung

The circulator may be installed in heating and conditioning systems on either the delivery pipe or the return pipe; the arrow marked
−
on the pump body indicates the direction of flow.
Install the circulator as far as possible above the minimum boiler level and as far as possible from bends, elbows and junction
−
boxes.
To facilitate control and maintenance operations, install an interception valve both on the suction pipe and on the delivery pipe.
−
Before installing the circulator, accurately flush the system with only water at 80°C. Then drain the system completely to eliminate
−
any harmful substance that may have got into circulation.
Avoid mixing additives derived from hydrocarbons and aromatic products with the circulating water. It is recommended that the
−
addition of antifreeze, where necessary, should not exceed 30%.
In the event of heat insulation use the special kit (if provided) and ensure that the condensate draining holes in the motor casing
−
are not closed or partly blocked.
In the case of maintenance, always use a set of new gaskets.
−
Never insulate the electronic control device.
