When the pressure is equalised at the manometers, the system is ready for compressor start up.
The fine-
tuning (remaining load) of the system must be carried out via the “
LOW
”
aspiration pipe
very slowly (with
the compressor in operation). To this end the loading must be carried out slowly by the Aspiration Line until we
attain a difference of 20 ºC between the atmospheric Temperature and the aspiration Temperature (for low pressure
manometers with readings in
VAPOUR
!!).
Or there should be as close an approximation as possible to the following aspiration pressure values for the
respective exterior temperature (atmospheric temp. at the panels). This values are estimated for water return
temperatures of between 25

You may not achieve exactly the desired pressure as this depends on some factors such as:
✓
Direct solar radiation on the panels;
✓
Ventilation;
✓
Relative humidity of the air;
✓
Variation in distances and unevenness of the installation piping;

Hydraulic Connections
The installation of the hydraulic system must be carried out by a competent professional, always
respecting the indications supplied by ENERGIE.
The Combi Block is fitted with a water circulator pump, according with the following graphic:
