4 WATER CONNECTION
WATER QUALITY
The water quality can be checked by qualified
personnel.
Water with inadequate characteristics can cause.

pressure drop increase

energy efficiency decrease

corrosive symptom increase
Water features

confirming to local regulations

Water hardness < 14°fr

within the limits indicated by table
Anti-freeze solutions
Consider that the use of anti-freeze solution
determines an increase in a pressure drop.
Make sure that the glycol type utilized is inhibited (not
corrosive) and compatible with the hydraulic circuit
components (pump etc).
Do not use different glicol mixture (i.e. ethylic with
propylene)
Water flow-rate
The design water flow-rate must be:

inside the exchanger operating limits (see the
TECHNICAL INFORMATION chapter)

guaranteed also with variable system conditions
(for example, in systems where some circuits are
bypassed in particular situations)
Minimum system water content
Minimum system water contents are given in the
‘General technical data’ section and they have to be
satisfied to stop the compressor from continuously
switching on and off.
Victualic connections
Standard: type Victaulic
Option: to be welded

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 from failure to clean the systems.
Risk of freeze
If the unit or the relative water connections can be
subject to temperatures close to 0°C

Mix water with ethylene glycol

Safeguard the pipes with heating cables placed
under the insulation

Empty the system in cases of long non-use

Water filter
Use filter with mesh pitch:
0,5 mm (30 mesh)

Must be installed immediately in the water input of
the unit, in a position that is easily accessible for
cleaning.

The filter never should be removed, this operation
invalidates the guaranty
