4 Positioning
During positioning consider these elements:
• Shafts required by the unit
• Electrical connections
• Water connections
• Spaces for air exhaust and intake
4.1 Functional spaces
Functional spaces are designed to:
• guarantee good unit operation
• carry out maintenance operations
• protect authorized operators and exposed people
Respect all functional spaces indicated in the DIMENSIONS section.
Double all functional spaces if two or more unit are aligned.
4.2 Positioning
Units are designed to be installed:
• EXTERNAL
• in xed positions
Limit vibration transmission:
• use antivibration devices on unit bearing points
• install exible joints on the hydraulic
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
• avoid ood-prone places
• 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
• condensate water draining
Prefer places where the unit doesn’t disturb the neighbours.
Avoid installations next to bedrooms or windows.
Avoid snow accumulations on batteries.
A correct circulation of the air is indispensible to guarantee the good working order of the machine.
Avoid therefore:
• obstacles to the airow
• exchange diculties
• leaves or other foreign bodies that can obstruct the exchange batteries
• winds that hinder or favour the airow
• heat or pollution sources close to the unit (chimneys, extractors etc..)
• stratication (cold air that stagnates at the bottom)
• recirculation (expelled air that is sucked in again)
• positioning below the level of the threshold, close to very high walls, attics or in angles that could give rise to stratication or recirculation
phenomenons
Ignoring the previous indications could:
• energy eciency decrease
• blocks due to HIGH PRESSURE (in summer) or LOW PRESSURE (in winter)
A. Keep the min. distances from the podestrian areas.
B. Provide windbreaks in locations with strong winds.
C. Avoid snow accumulations on batteries.
D. Install the unit lifted from the ground.
E. Provide a protection.

M0R940E13-00 WSAN-XIN 21-141 11
4.3 Condensate water
When a heat pump is running it produces a considerable amount of water due to the defrosting cycles of the external coil.
The condensation must be eliminated in a manner to avoid wetting pedestrian areas.
The unit anti-freeze electric resistance prevents the ice from forming inside the tray.
With extensive very cold outdoor temperatures, condensation could freeze outside the unit blocking the ow and causing a slow build-up of
ice; therefore special attention must be paid to eliminating condensation, raising the unit o the ground and evaluating whether antifreeze
elements should be installed.
A. Condensation collection basin
B. Unit support
C. Condensate discharge connection Ø 13

5 Water connections
5.1 Water quality
The water quality can be checked by qualied personnel.
Water with inadequate characteristics can cause:
• pressure drop increase
• energy eciency decrease
• corrosive symptom increase
Acceptable water quality values:
Provide a water treatment system if values fall outside the limits.
5.2 Risk of freeze
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
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.
Do not use dierent glicol mixture (i.e. ethylic 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
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.

6 Electrical connections
The characteristics of the electrical lines must be determined by specialized personnel able to design electrical installations; moreover, the
lines must be in conformity with regulations in force.
The protection devices of the unit power line must be able to stop the presumed short circuit current, whose value must be determined in
function of system features.
The power cables and the protection cable section must be dened in accordance with the characteristics of the protections adopted.
All electrical operations should be performed by trained personnel having the necessary requirements by the regulations in force and being
informed about the risks relevant to these activities.
Operate in compliance with safety regulations in force.
6.1 Electrical data
The serial number label reports the unit specic electrical data, included any electrical accessories.
The electrical data indicated in the technical bulletin and in the manual refer to the standard unit, accessories excluded.
It reports the regulations indications such as:
• Voltage
• F.L.A.: full load ampere, absorbed current at maximum admitted conditions
• F.L.I.: full load input, full load power input at max. admissible condition
• Electrical wiringdiagram Nr.
If the DHW module is present, consider the electric resistance absorption in the power supply line dimensionino.
6.2 Connections
1. Refer to the unit electrical diagram (the number of the diagram is shown on the serial number label).
2. Verify that the network has characteristics conforming to the data shown on the serial number label.
3. Before starting work, verify that the sectioning device at the start of the unit power line is open, blocked and equipped with cartel
warning.
4. Primarily you have to realize the earthing connection.
5. Shelter the cables using adequate measure fairleads.
6. Before power the unit, make sure that all the protections that were removed during the electrical connection work have been restored.
6.3 Signals / data lines
Do not overpass the maximum power allowed, which varies, according to the type of signal.
Lay the cables far from power cables or cables having a dierent tension and that are able to emit electromagnetic disturbances.
Do not lay the cable near devices which can generate electromagnetic interferences.
Do not lay the cables parallel to other cables, cable crossings are possible, only if laid at 90°.
Connect the screen to the ground, only if there aren’t disturbances.
Guarantee the continuity of the screen during the entire extension of the cable.
Respect impendency, capacity and attenuation indications.
