Drain the coils during commissioning.
It is recommended to carry out a bacteriological analysis (detection of ferrobacteria,
bacteria producing H2S and reducing sulphates) and a chemical analysis (to avoid
problems with scaling and corrosion) of the water.

Humidity).
- Recommended supply air temperature:
To prevent any inopportune opening of the thermo-actuators on control valves with
thermal motors, the temperature of the air surrounding the thermo-actuators should
not exceed 50°C. This is especially important for units installed in confined spaces
(e.g. in suspended ceilings).
To protect against the risk of condensation when using chilled water, lagging should
be placed along the entire lengths of pipes and completely sealed at its ends.
When using the water coil and electric heater, we advise against using cross-linked
the electric heater could cause the water temperature to rise briefly. This could cause
We recommend using stainless steel braided (or equivalent) hoses for hydraulic
connections.
