•
Choose the installation place according to the following criteria:
Customer approval
•
safe accessible position
•
technical spaces requested by the unit
•
spaces for the air intake/exhaust
•
The device prevents any impurity in the water circuit to dirt the heat exchanger.
•
verify unit weight and bearing point capacity
•
verify that all bearing points are aligned and leveled
•
install the unit raised from the ground
•
max. distance allowed by the electrical connections
•
Prefer places where the unit doesn’t disturb the neighbours.
Avoid installations next to bedrooms or windows.
A correct circulation of the air is mandatory to guarantee the good unit operating.
Avoid therefore:
obstacles to the airow
•
diculty of exchange
•
leaves or other foreign bodies that can obstruct the air coil
•
winds that hinder or favour the airow
•
heat or pollution sources close to the unit (chimneys, extractors etc..)
•
stratication (cold air that stagnates at the bottom)
•
recirculation (expelled air that is sucked in again)
•
incorrect positioning, close to very high walls, attics or in angles that could give rise to stratication or recirculation phenomenons
•
Ignoring the previous indications could:
reduce energy eciency
•
alarm lockout due to HIGH PRESSURE (in summer) or LOW PRESSURE (in winter)
•

5 Water connections
5.1 Water quality
Water features
conrming to local regulations
•
total hardness < 14°fr
•
within the limits indicated by table
•
The water quality must be checked by qualied personnel.
Water with inadequate characteristics can cause:
pressure drop increase
•
reduces energy eciency
•
increased corrosion potential
•
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.
5.2 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
•
5.3 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 dierent glicol mixture (i.e. ethylene with propylene).
5.4 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).

5.5 Operation sequence
Close all vent valves in the high points of the unit hydraulic circuit
Close all drain valves in the low points of the unit hydraulic circuit:
Heat exchangers
•
Pumps
•
collectors
•
storage tank
•
free-cooling coil
•
1. Carefully wash the system with clean water: ll and drain the system several times.
2. Apply additives to prevent corrosion, fouling, formation of mud and algae.
3. Fill the plant
4. Execute leakage test.
5. Isolate the pipes to avoid heat dispersions and formation of condensate.
6. Leave various point of service free (wells, vent-holes etc).
Neglecting the washing will lead to several lter cleaning interventions and at worst cases can cause damages to the exchangers and the
other parts.
