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.
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").
Reminder: if one of these factors is situated at its minimum or maximum level, the other should be
situated at a normal level in order to ensure the unit’s correct and normal operation.
2. Ensure that the thermostat is connected properly and set the set temperature below the ambient
temperature of the zone to be cooled. After 3 minutes, the compressor starts operating.
3. When the appliance has been operating for a few minutes, check the presence of cold air at the
blowing grille.
4. When the appliance has been operating for a few minutes, check the temperature of the unit’s outlet
water. Generally, this should be around 5°C above the unit’s water loop inlet temperature. A variance
lower than 3.5°C indicates that the water flow is too high, whilst a variance higher than 8°C indicates
that the water flow is too low.
5. Adjust the isolation/balancing valve on the outlet water pipe to obtain the appliance’s nominal water
flow (Refer to the Maker’s Plate)
6. Check that the condensates drainage system is working properly and check that a siphon is included
in the drainage line.
7. Check for the absence of vibrations and water leaks.
8. When all the above tests have been completed, adjust the system to maintain the desired comfort
level.
