M01Z40E12-03 WSA-XSC2 432-120D 9
3 Positioning
During positioning consider these elements:
• Technical spaces requested by the unit
• Electrical connections
• Water connections
• Spaces for air exhaust and intake
3.1 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.
3.2 Positioning
Units are designed to be installed:
• INTERNAL
• in xed positions
Limit vibration transmission:
• use antivibration devices on unit bearing points
• install exible joints on the hydraulic connections
Choose the installation place according to the following criteria:
• safe accessible position
• 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
A correct circulation of the air is mandatory to guarantee the good unit operating.
Avoid therefore:
• obstacles to the airow
• diculty of exchange
• leaves or other foreign bodies that can obstruct the air coil
• 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)
• incorrect positioning, close to very high walls, attics or in angles that could give rise to stratication or recirculation phenomenons
Ignoring the previous indications could:
• reduce energy eciency
• alarm lockout due to HIGH PRESSURE (in summer) or LOW PRESSURE (in winter)
3.3 Saftey valve gas side
The installer is responsible for evaluating the opportunity of installing drain tubes, in conformity with the local regulations in force (EN 378).
3.4 Air channelling
When designing and manufacturing the ducting, consider LOAD LOSSES, AIR FLOW AND SPEED that must be consistent with the unit features.
Limit the load losses by optimising the path, the type and number of bends and junctions.
Consider that excessive external static pressure will lead to a reduction in ow rate, with consequent alarm lockout.
Ensure ducts are thermally insulated.
The weight of the ducting must not burden the connection anges.
Place anti-vibration joints between channels and unit.
Connection to the anges and between the various sections of the channels must guarantee air seal, avoiding dispersions penalising the
overall eciency of the system.

10 WSA-XSC2 432-120D M01Z40E12-03
Vertical outlet standard (1)
Rear outlet option (2)
Provide:
• water discharge (3-A)
• grilles to restrict access to small animals (3-B)
• deectors (3-C) to avoid the by-pass between the two air ows
• safety grille (4-D)
Avoid therefore:
• angle curves and narrowings (5)
• direct air ow on people (6-7), windows, doors, plants, obstacles in general
• obstacles that prevents the air inow to the coil (8-9)
• installations next to silent rooms

M01Z40E12-03 WSA-XSC2 432-120D 11
4 Water connections
4.1 Water quality
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.
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 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.

12 WSA-XSC2 432-120D M01Z40E12-03
4.6 Racommended connection
The installer must dene:
• component type
• position in system

2 piping support 10 thermometer
3 exchanger chemical cleaning bypass 11 shut-o valve
4 shut-o valve 12 lter
5vent 13 lling valve
6 expansion vessel 14 shut-o valve
7 safety valve 15 Internal storage tank
8 Flow Switch 16 Cleaning system bypass
4.7 Water lter
It must be installed immediately in the water input of the unit, in a position that is easily accessible for cleaning.
The lter never should be removed, this operation invalidates the guaranty.
4.8 Hydraulic connections
A - standard
B - standard quick connections ush to the unit
C - connections ush the unit (option)
An option which simplies the hydraulic connections which would otherwise be carried out within the unit (with the responsibility of the
client).
Includes internal piping to the external unit panel, two fast ttings ush to the unit, two outlet connections for the system connections which
are to be soldered by the client.

5 Electrical connections
The characteristics of the electrical lines must be determined by qualied electrica 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 all short circuit current, the value must be determined in accordance with
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 qualications required by the regulations in force
and being informed about the risks relevant to these activities.
Operate in compliance with safety regulations in force.
5.1 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.
The matriculation plate shows the indications foreseen by the standards, in particular:
• 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.
5.2 Connections
1. Refer to the unit electrical diagram (the number of the diagram is shown on the serial number label).
2. Verify that the electrical supply has characteristics conforming to the data shown on the serial number label.
3. Before starting work, ensure the unit is isolated, unable to be turned on and a safety sign used.
4. Ensure correct earth connection.
5. Ensure cables are suitably protected.
6. Before powering up the unit, make sure that all the protections that were removed during the electrical connection work have been
restored.
5.3 Signals / data lines
Do not exceed 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.
5.4 Power input
Fix the cables: if vacated may be subject to tearing.
The cable must not touch the compressor and the refrigerant piping (they reach high temparatures).
