3.2 Functional spaces

The functional spaces have the aim of:

 guarantee good operation of the unit  allow maintenance operations  protect the authorised operators and exposed

persons. Respect the functional spaces indicated in the TECHNICAL INFORMATION chapter Double the functional spaces if more units are aligned.

3.3 Positioning

The units have been designed to be installed :

 OUTDOORS  INDOORS (OPTION)  in permanent position.

Choose the place of installation depending on the following criteria:

 level of sound emissions admitted by the local

standards

 Customer approval  safely accessible position  technical spaces requested by the unit  maximum distance admitted from the electric

connections

 support points with adequate capacity for the unit

weight

 spaces for air ejection and suction  disposal of condensate water

Prefer places where the unit does not disturb neighbours. Avoid snow accumulating obstructing the coils Avoid places that may be subject to floodings Install the unit lifted from the ground. Protect the unit with suitable fence in order to avoid access to unauthorised personnel (children, vandals, etc.) Limit the transmission of vibrations:

 use anti-vibration devices or neoprene strips on the

unit support points

 install flexible joints on the hydraulic connections  install flexible joints on the aeraulic connections.

A correct air circulation on the coil is essential to guarantee the good operation of the machine. Avoid:

 obstacles to air flow (strong prevailing winds, hedges,

fences, etc.)

 difficulty of exchange  leaves or other bodies that can obstruct the exchange

coils

 winds contrasting or favouring the air flow  heat sources near the unit (chimneys, extractors, etc.)  sources of dust or pollutants  stratification (cold air that stagnates at the bottom)  recirculation (ejected air that is taken back via suction)  positioning underneath the ground level, near very

high walls, underneath roofs or in corners (can give rise to stratification or recirculation phenomena).

Neglecting the previous indications can lead to:

 worsening of the energy efficiency.  blocks due to HIGH PRESSURE (in summer) or LOW

PRESSURE (in winter). Avoid snow and ice accumulation in front of the external air outlets and of the exhaust air ejection.

4 - HYDRAULIC CONNECTIONS

4.1 Condensate drain

The condensate must be disposed of in order to avoid damaging things and persons.

 Unit drain coupling: the connection must not transmit

mechanical stresses and must be carried out paying attention not to damage the unit drain coupling.

 Foresee a siphon that, by eliminating the depression

caused by the fan, prevents suction of air from the drain piping.

 The piping must have adequate slope to allow out flow.  Anchor the piping with an adequate number of supports.  On the contrary, cracking in the piping and air pockets

obstructing the outflow, are generated.

 Isolate piping and siphon to avoid condensate dripping.  Connect the condensate drain to a rain drain network.  DO NOT use white waters or sewage drains to avoid

possible inhaling of odours in case of evaporation of the water contained in the si phon.

 At work end, check the regular outflow of the condensate

by pouring water in the bowl.

4.2 Risk of freezing

Adopt measures to prevent risk of freezing if the unit or relative hydraulic connections can be subject to temperatures near 0°C.

 isolate the piping  protect the piping with heating cables laid underneath

the insulation

4.3 Hydronic recovery - option

The device is shipped filled with water and glycol.

Siphon height calculation T = 2P S = T/2 P is the pressure determined by the fan in correspondence of the condensate collection bowl (approx. 1 mm = 9.81 Pa)

Example :

P = 300 Pa = 30 mm T = 2P = 60 mm S = T/2 = 30 mm

4 - HYDRAULIC CONNECTIONS

4.4 Immersed electrodes humidifier - option

SUPPLY WATER The humidifier must be supplied with mains water having the

following features:

 pressure between 0.1 and 0.8 Mpa (1 – 8 bar)  temperature between 1 and 40°C

Do not use :

 water treated with softeners: it can corrode the

electrodes and form foam with possible faults/ malfunctionings

 pit, industrial or potentially polluted (chemically or

bacteriologically) water

 disinfectants or anti-corrosive substances mixed with

water, as potentially irritating

Supplying the humidifier with water treated with reverse osmosis filtering system gives the following advantages:

 reduces limescale deposits  reduces energy consumptions  reduces maintenance costs  increases humidifier duration.

Check that the filter guarantees a water flow rate higher than the flow rate of the installed humidifier.

DRAINAGE WATER It can reach a temperature of 100°C. It contains the same substances of the supply water but in

higher concentration. As it is not toxic, it can be disposed of with white waters.

5 - AERAULIC CONNECTIONS

5.1 Generality

The dimensioning and correct execution of the aeraulic connections are fundamental to guarantee good unit operation and adequate level of silence in the room.

When designing and manufacturing the channels, consider LOAD LOSSES, AIR FLOW AND SPEED that must be consistent with the unit features.

Particularly consider that load losses higher than the unit useful prevalence, lead to reduction in flow rate, with consequent unit blocks.

 the weight of the channels must not burden on the

connection flanges

 place anti-vibration joints between channels and unit  connection to the flanges and between the various

sections of the channels must guarantee air seal, avoiding dispersions penalising the overall efficiency of the system

 limit the load losses by optimising the path, the type and

number of bends and junctions

 use wide bends evaluating the opportunity of equipping

them with deflectors (in particular with high air speed or bends with reduced radius).

5.2 Treated air channelling

The internal surface of the channel must be smooth, enable its washing and must not contaminate the air

Thermally isolate the channels and the flanges to avoid energy losses and forming of condensation

DIFFUSERS INLETS GRILLES A correct diffusion of the air in the room is determining for the

level of comfort. When choosing and positioning the grilles, inlets and

diffusers, avoid:

 excessive air speed  forming of stagnant and stratification areas  cold air delivery in room  forming of localised currents (also due to uneven

distribution of air)

 excessive room temperature variations, vertically and

horizontally

 short circuits of the supply air towards the return air.

For sound comfort, consider that :

 the air diffusers must be chosen verifying the sound power

generated at nominal flow rate conditions

 the cut-off to diffusers must be carried out with flexible

elements

 the return grilles must be widely dimensioned.

Thermally isolate the channels and the flanges to avoid energy losses and forming of condensation

7.1 Preliminary information

The indicated operations must be carried out by qualified technicians and specifically trained on the product.

Upon request, the after-sales assistance centres execute startup.

The electric, hydraulic connections and the other work of the system are the responsibility of the installer.

Agree the start-up date with the after-sales assistance centre with sufficient advance

7.2 Preliminary checks

Before starting any check, verify that :

 the unit is perfectly installed and in compliance with that

reported in this manual

 the electric power supply line of the unit is isolated at start-

 the isolation device of the line is open, blocked and

equipped with relative signal.

7.3 Cooling circuit

7.5 Electric circuit

Check the unit is connected to the earth system. Check fastening of the conductors: the vibrations caused by handling and transport may cause loosening.

Power the unit by closing the isolation device but leave in OFF.

Check the network frequency and voltage values, that are within the limits:

400/3/50 +/- 10% Check the unbalancing of the phases:

must be below 2% . Example :

1. Visually check the cooling circuit: any oil stains can be symptom of leaks (caused by, for example, transport, handling or other).

2. Check the cooling circuit is pressurised: use the machine pressure gauges, if present, or service pressure gauges.

3. Check all service sockets are closed with relative plugs; their absence may determine coolant leaks

7.4 Hydraulic circuit

Only with hot water coil - humidifier options

1. Find out if, before connecting the unit, the hydraulic

system has been washed and the washing water drained.

2. Check the hydraulic circuit has been loaded and

pressurised.

3. Check the shut-off valves on the circuit are in "OPEN"

position.

Operation outside the limits can entail irreversible damages.

7.6 Compressor carter resistors

Power the compressor oil heating resistors for at least 8 hours before starting the compressor itself:

 upon unit commissioning  after every prolonged stop period with unit not

powered

Power the resistors by closing the unit isolator. Check electric absorption of the resistors to be sure they are

working. Execute start only if the temperature of the compressor casing

on the lower side is at least 10°C higher than the outdoor temperature.

Do not start the compressor with carter oil not in temperature.

7 - START-UP

7.7 Voltages

Check the air and water temperatures are within the operational limits.

Start the unit; refer to the "Adjustment" section for indications on the control system.

With the unit running, meaning in stable conditions and near the work ones, check:

 power supply voltage  unit overall absorption  absorption of the individual electric loads.

7.8 Scroll compressors (size 2, 3, 4, 5, 6)

The Scroll compressors have only one direction of rotation. In the event that the direction is reversed, the compressor will

not be damaged, but its noisiness will increase and pumping will be negatively affected.

After a few minutes, the compressor will stop because of the activation of the thermal protection.

In this event, cut the power and reverse the 2 phases on the machine power.

Prevent the compressor from working with in reverse rotation: more than 2-3 anomalous starts up can damage it.

Make sure the direction of rotation is correct, measure the condensation and suction pressure.

Pressure must clearly differ: at the start, the suction pressure decreases whilst the condensation pressure increases.

7.9 Remote consents

Check the remote controls (ON-OFF, etc.) are connected and, if necessary, enabled with relative parameters

(ELECTRIC CONNECTIONS sections and following pages)

Check the probes or optional components are connected and enabled with the relative parameters.

7.14 Start-up report

To detect the objective operational conditions is useful to control the unit over time.

With the unit running, meaning in stable conditions and near the work ones, detect the following data:

 Overall absorptions and voltages with unit in full load  Absorptions of the various electric loads

(compressors, fans, pumps etc)

 Temperatures and flow rates of the various fluids

(water, air) at input and output of the unit

 Temperatures and pressures in the feature points of

the cooling circuit (compressor, liquid, suction drain/ unload)

The detections must be kept and made available during maintenance interventions.

7.15 EC Directive 97/23 PED

From Directive 97/23 EC PED derive the prescriptions for the installers, the users and the maintenance operators of the unit also.

Refer to the local implemented standards; in synthesis and for merely indicative purposes:

 Compulsory check of first system:

only for units assembled on site by the installer (e.g. condensing + direct expansion unit)

 Declaration of start-up:

for all units

 Periodical checks:

to be carried out as frequently as defined by the Manufacturer

(see MAINTENANCE section) .

7.10 Operation type setting

Refer to 7.11, 7.12, 7.13.

1. Define operation type

- maximum capacity available (MC)

- constant supply control (CS)

- high air flow (HA)

2. set air flow setpoint

3. set temperature setpoint

4. set humidity setpoint

5. confirm setting

7 - START-UP

7.11 Maximum capacity available (MC)

In this operating mode, the supply air temperature (T_SA) can vary in accordance with the temperature of the air extracted from the room (T_RA) and their deviation from the set value.

Therefore, there is feedback from the room. In cooling mode the humidity control of the supply air is standard and a priority.

7.12 Constant supply control (CS)

In this operating mode the external air is treated based on the supply conditions set in accordance with one of the following two criteria:

 with two fixed seasonal setpoints, for operation in cooling and heating mode  with two dynamic seasonal setpoints, in which the supply temperature is offset automatically in accordance with the external dry

bulb temperature T_OA, with climatic regulation.

There is no feedback from the room. In cooling mode the humidity control of the supply air is standard and a priority.
