Setting the system flow rate
Checking and adjusting the flow rate
Adjust the flow rate when the system is cold (approx 20°C)
(see Fig. 30).
The flow rate should be adjusted to give the optimum flow
rate depending on the number and type of collector(s)
connected.
Manually operate the solar pump (See page 28 – Manual
Operation).
Set the solar pump speed selector (Fig. 30 Item 5) so that the
required flow rate is achieved or exceeded with the lowest
possible setting. The flow limiter adjusting screw (Fig. 30
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 6).
The float in the flow meter will indicate the circulation flow
rate through the flow meter sight glass (Fig. 30 Item 4).
Adjust screw of the flow limiter (Fig. 30 Item 3) with a
screwdriver, until the upper edge of the float in the sight
glass indicates the required flow rate (Fig. 30 Item 4). Turn
the screw anticlockwise to increase the flow.
Ensure that the float is stable when the pump is running.
Unstable flows may indicate air is trapped within the system.
Follow procedure on page 24 to remove air entrapped.
Check and if necessary reset flow after removal of air.
Set manual pump operation to off (See page 28 – Manual
Operation).
12.2 Installation of the thermal insulation
Refit the controller mounting moulding (Fig. 31 Item 1) onto
the rear moulding.
Push the front thermal insulation (Fig. 31 Item 2) against the
rear thermal insulation section (Fig. 31 Item 3) until it clips
into place.
Benchmark™ Log Book
On completion of the installation and commissioning
procedures detailed in this Product Guide the Benchmark™
“Installation, Commissioning and Service Record Log,
pages 48 and 49” should be completed and signed off by
the competent installer or commissioning engineer in the
relevant sections. The various system features, location
of system controls, user instructions and what to do in
the event of a system failure should be explained to the
customer. The customer should then countersign the
Benchmark™ commissioning checklist (page 48) to accept
completion. The Service Record (page 50) should be filled
in when any subsequent service or maintenance operation
is carried out on the Megaflo Eco SolaReady unit (See
Maintenance and Servicing, page 37).

12.0 Setting the system flow rate
12.1 Checking and adjusting the flow rate
1. Adjust the flow rate when the system is cold (approx 20°C)
(see Fig. 36).
2. The flow rate should be adjusted to give the optimum flow
rate depending on the number and type of collector(s)
connected.
3. Manually operate the solar pump (See Section 11.5).
4. Set the solar pump speed selector (Fig. 36 Item 5) so that
the required flow rate is achieved or exceeded with the
lowest possible setting. The flow limiter adjusting screw (Fig. 36
Item 3) can be used to fine-tune the flow rate.
5. Depending on the number and type of collectors installed,
set the required flow rate from table (See Table 1).
6. The float in the flow meter will indicate the circulation flow
rate through the flow meter sight glass (Fig. 36 Item 4).
7. Adjust screw of the flow limiter (Fig. 36 Item 3) with a
screwdriver, until the upper edge of the float in the sight glass
indicates the required flow rate (Fig. 36 Item 4). Turn the screw
anticlockwise to increase the flow.
8. Ensure that the float is stable when the pump is running.
9. Set manual pump operation to off (See Section 11.5).
12.2 Installation of the thermal insulation
1. Refit the controller mounting moulding (Fig. 37 Item 1)
onto the rear moulding.
2. Push the front thermal insulation (Fig. 37 Item 2) against the
rear thermal insulation section (Fig. 37 Item 3) until it clips into
place.
