Monobloc Outdoor Unit Installation Manual
11.0 Start Up
Before operating your system, for the first time, please complete the following checks:
1. Is there any shipping damage?
2. Unit is level in its installation
3. Power supply agrees with the unit name plate
4. Electrical circuit wiring has been sized and installed properly
5. Unit ground wire has been connected
6. Unit neutral wire has been connected
7. All terminals are tight
8. All cables and thermistors have been inspected for crossed wires
9. All plug assemblies are tight
10. All air handlers are operating
11. All water valves are open
12. All fluid piping is connected properly
13. All air has been vented from the system
14. Water pump is operating with the correct rotation
15. Water pump control has been properly interlocked with the heat pump
16. Unit has been leak checked (including fittings): Locate, repair, and report any refrigerant leak
17. All incoming power voltage is within rated voltage range
As part of the setup for your system it is important that the nominal flow rate, for the system is determined and that
all air is purged from the water pipework / heating circuit. Details on how to set the nominal flow rate and how to
purge the air from your system are shown below:
11.1 Nominal system water flow control:
The water circulation pumps of the RUA-CP***1H units have been sized to allow the hydronic modules to cover
all possible configurations based on the specific installation conditions, i.e. for various temperature differences
between the entering and the leaving water (ΔT) at full load, which can vary between 3 and 10 K.
This required difference between the entering and leaving water temperature determines the nominal system flow
rate. Use this specification for the unit selection to find the system operating conditions. In particular, collect the
data to be used for the control of the system flow rate:
• Unit without a hydronic module (with external main pump): nominal unit pressure drop (plate heat exc
internal piping),
• Unit with fixed speed pump: nominal available external static pressure,
• Units with variable speed pump-control on adjustable constant speed: nominal flow rate,
• Units with variable speed pump - control on temperature difference: heat exchanger ΔT (variable flow).
If the information is not available at the system start-up, contact the technical service department responsible
for the installation to get it. These characteristics can be obtained from the technical literature using the unit
performance tables for a ΔT of 5 K at the water heat exchanger.
