9. HYDRAULIC DIAGRAMS AND CONFIGURATIONS
CAUTION:
Managing the primary circuit flow rate is essential to
ensure product performance and service life. The flow
setting value must be adapted to suit the application.
Refer to the sizing study.
It is essential to install regulator valves (not supplied) on the decoupling tank return and
on the return from every heat pump if a cascade installation is used.
When a cascade installation is used, the flow must be balanced between all units. We
recommend performing this balancing using balancing valves so that individual flow
levels can be measured over time.
CAUTION:
Flow adjustment and checking are the responsibility of
the installer/operator and will not be performed by Ideal.
When the system is commissioned, a balance check
will be required by Ideal. If no check is performed,
commissioning will be refused.
