4 Water connections
4.1 Water quality
Water features
•
conrming to local regulations
•
total hardness < 14°fr
•
within the limits indicated by table
The water quality must be checked by qualied personnel.
Water with inadequate characteristics can cause:
•
pressure drop increase
•
reduces energy eciency
•
increased corrosion potential
Acceptable water quality values:
Provide a water treatment system if values fall outside the limits.
The warranty does not cover damages caused by limestone formations, deposits and impurities from the water supply and / or failure from
failed system clearing to clean system.
4.2 Risk of freezing
If the unit or the relative water connections are subject to temperatures close to 0°C:
•
mix water with glycol, or
•
safeguard the pipes with heating cables placed under the insulation, or
•
empty the system in cases of long non-use
4.3 Anti-freeze solution
The use of an anti-freeze solution results in an increase in pressure drop.
Make sure that the glycol type utilized is inhibited (not corrosive) and compatible with the water circuit components.
Do not use dierent glicol mixture (i.e. ethylene with propylene).
4.4 Water ow-rate
The project water-ow must be:
•
inside the exchanger operating limits (see the TECHNICAL INFORMATION section)
•
guarantee, also with variable system conditions (for example in systems where some circuits are bypassed in particular situations).
4.5 Minimum system water content
Minimum system water volumes are described within ‘General technical data’ section and they have to be satised to avoid continuous
compressor switching on and o.
