CIAT COMFORT LINE Instruction Manual page 39

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.

Cooling coil inlet minimum water temperature: 5°C
Heating coil inlet maximum water temperature (2-tube application without electric
heaters): 70°C
Heating coil inlet maximum water temperature (2-tube application with electric heaters
operating simultaneously): 55°C
Heating coil inlet maximum water temperature (4-tube application):
Maximum operating pressure: 16 bar
Interior return air min./max. temperature: +0°C/+40°C
Indoor return air maximum humidity level:
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).
CIAT shall not be liable for damage to valves caused by faulty design of the hydraulic
supply network or incorrect commissioning.
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
polyethylene (PEX) pipes to supply water to the unit. This is because overheating
of the electric heater could cause the water temperature to rise briefly. This could
cause the rapid deterioration of the PEX pipe near the unit and cause it to burst. We
recommend using stainless steel braided (or equivalent) hoses for hydraulic connections.
