User Interface Position

Always install the EVOSTA2, EVOSTA2d circulator with the motor shaft in a horizontal
position.
Install the electronic control device in a vertical position.

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.
