IOM SYSAQUA 20 40 (IOM AQA 04 N 4GB)

14 SYSAQUA
For refrigeration only units, the total volume on the level of the primary water circuit must never below:
² application air conditioning
 3.5 L/kW refrigeration power
² application process
 10 L/kW refrigeration power
10.3. MINIMUM WATER VOLUME REQUIREMENTS
To ensure that the system operates correctly you must use suitably sized and properly routed pipes for the
hydraulic links between the SYSAQUA and the mains network. Proper operation of the regulation and safety
devices is ensured only when the water volume is sufcient.
10.3.1. SYSAQUA COOLING ONLY VERSION
10.3.2. SYSAQUA HEAT PUMP VERSION
For reversible units, a water volume equal to 12.5 L/kW is recommended, so that energy reserves are full
enough to ensure the defrosting cycle without any discomfort for the end user.
If the total volume of the primary hydraulic circuit does not allow to reach these recommendations, a buffer
tank must be added to the installation to increase the water volume up to the value required.
If the unit runs with a low volume of water (with air treatment plant…) or if it is used for industrial processes,
a buffer tank is compulsory to guarantee sufcient thermal inertia and satisfactory temperature stability.
10.4. MAXIMUM WATER VOLUME REQUIREMENTS
The maximum water volume is limited by the sizing of the unit's expansion tank and/or the expansion tank
present in the facility's hydraulic circuit. Expansion tanks must be sized according to the glycol percentage
in the hydraulic circuit.
Fully rinse all water pipes before nal connection to the SYSAQUA.
When using an off-the-shelf acid rinsing solution, implement a temporary branching around the SYSAQUA
to prevent damaging internal components (particularly the plate exchanger, ow switch, pump...).
10.5. RINSING THE CIRCUIT
Internal water tank :
² SYSAQUA 20-25-30-35-40  100L
The volume of the expansion tanks selected with Single pump and double pump options are :
The expansion tank should be installed at the pump suction, and the pressure inside will be adjusted by
taking into account the whole hydraulic circuit.

Before lling the installation, check it and remove any contamination such as sand, stone, welding
chips and other materials likely to damage the SYSAQUA.
