STARTING - RECOMMENDATIONS - SETTINGS
1. Check that all the water valves are open and that water circulates in the appliance before making
any demand for heating or cooling.
2. Ensure that the units are connected correctly to the mains power supply (Refer to "Electrical connection"
and "Wiring diagrams") for the type of supply: "SINGLE PHASE or THREE PHASE + NEUTRAL".
3. Before attempting any start-up, ensure that the air and water temperatures are within the appliance’s
operating limits (Refer to "Operating limits").
4. Rotate the fan by hand to ensure that it turns freely and that the fan turbine is properly attached to
the motor shaft.
5. Check that the condensates drainage pipe is properly attached and free of any blockages.
6. Check the correct positioning of the filters and that they a clean and accessible.
7. Ensure that the finned heat exchanger surfaces are clean. Clean if required.
8. Check that the connection hoses are correctly fitted and ensure that the appliance’s water circuit has
been correctly bled of any air.
9. Ensure that no Alarm code is displayed when the mains power supply is switched on (Refer to the
"Alarm code" chart).
10. Carry out the usual checks on the main water loop and particularly to ensure that the water circulation
pump operates correctly.
Non-compliance with this rule may result in irreversible damage to the plate exchanger.
In addition, we recommend the use of a flow controller on the units’ inlet pipe (not
supplied).
COMMISSIONING
After performing all the above-mentioned checks, proceed with creating a demand for Cooling and Heating or
vice versa.
DEMAND FOR COOLING
1. With the MODE key on the RCL control module, select COOL mode and then set the minimum
temperature with the UP and DOWN arrows. The ambient temperature should be within the operating
limits (Refer to "Operating limits"). In the same way, during the pre-commissioning checks, the exchanger
pump(s) water loop inlet temperature should be within the limits corresponding to each operating
mode (Refer to "Operating limits").
FINAL TASKS
Place the plugs back on the valves and check that they are properly tightened.
If needed, fix the cables and the pipes on the wall with clamping collars.
Operate the air conditioner in the presence of the user and explain all functions.
Show him how to remove, clean and place back the filters.
MOTORISED WATER VALVE
The W/V output on the STORM 2 can be used for a 230 V connection to supply a motorised water valve (the valve
motor capacity must not exceed 250 Watts).
When this valve is installed on the system, it limits main circulation pump energy consumption as well as limiting
the overall pressure losses in the hydraulic circuit.
Initially closed, the valve opens 30 seconds before the compressor starts and closes 20 seconds after it stops.
It is important that the valve opening time is less than 30 seconds.
