Special instructions for chilled water circuits
Chilled water circuits, in particular freon-to-water exchangers, are highly vulnerable to frost damage.
Consequences can be signifi cant: exchanger or compressor replacement, etc. Take all necessary precautions
to avoid such problems.
The installer shall make sure that:
>
Glycol is used as antifreeze protection.
>
Water fl ow rate is suffi cient in each exchanger.
>
Appropriate precautions are taken in case of prolonged shutdown.
Failure to comply with these instructions will void equipment guarantee.
Nota:
ETT will not be liable for frost damage.
The user shall:
• control regularly, using a density meter for example, that the circuit is well protected for the
effective outside temperature;
• start units regularly when shutdown to avoid deterioration;
• drain circuits when necessary (in case of power outage, failure, etc.).
