2.4Checking and adjusting the flow rate

Adjust the flow rate when the system is cold (20°C) (see Fig. 5).

The flow rate should be adjusted to give the optimum flow rate depending on the number and type of collector panels connected.

Turn the slot of the adjusting screw (Fig. 5 Item 1) below the return temperature gauge horizontally to close the non-return valve.

Turn the l.h. isolating valve with integral thermometer in the flow (Fig. 5 Item 2) as far as it will go in the direction indicated by the arrow to close the non-return valve (dot on bezel on top).

Turn the slot of the adjusting screw (Fig. 5 Item 3) in the return vertically to open the flow limiter on the flow meter (Fig. 5 Item 4).

Manually operate the solar pump (see section 3.1.7).

Set the solar pump switch (Fig. 5 Item 5) so that the required flow rate is achieved or exceeded with the lowest possible setting.The flow limiter adjusting screw (Fig. 5 Item 3) can be used to fine-tune the flow rate.

Depending on the number and type of collectors installed, set the required flow rate from table (See Table 1).

The float in the flow meter will indicate the circulation flow rate through the flow meter sight glass.

Adjust screw of the flow limiter (Fig. 5 Item 3) with a screwdriver,until the upper edge of the float in the sight glass indicates the required flow rate.

Set manual pump operation to off.

2.5Installation of the thermal insulation

Refit the controller mounting moulding (Fig. 6 Item 1) onto the rear moulding.

Push the front thermal insulation (Fig. 6 Item 2) against the rear thermal insulation section (Fig. 6 Item 3) until it clips into place.
