3 - POSITIONING

3.1 PRELIMINARY INFORMATION

Operate in compliance with safety regulations in force.
For detailed information (dimensions, weight, technical

characteristics etc.) please refer to the TECHNICAL
INFORMATION section.

Use single protection devices : gloves, glasses ecc.

During positioning consider these elements :

 technical spaces required for the machine and system
 place where the machine will be installed
 electrical connections
 water connections
 air / aeraulic ducts

Do not considerer these elements could decrease
performances and operational life of the unit.

3.2 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 TECHNICAL
INFORMATION section.

Double all functional spaces if two or more unit are aligned.

3.3 POSITIONING

Units are designed to be installed:

 EXTERNAL
 in fixed positions.

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
 max. distance allowed by the electrical connections
 control points with capacity adequate to the unit weight
 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.
Avoid installations in places subject to flooding
In case of ground installation provide a raised base to avoid

flood damages.
Protect the unit with an appropriate fencing to avoid the

access to a not authorized personnel (babies, vandals etc.)

Limit vibration transmission:

 use antivibration devices on unit bearing points;
 install flexible joints on the hydraulic.

A correct circulation of the air is indispensible to guarantee the
good working order of the machine.

Avoid therefore:

 obstacles to the airflow;
 exchange difficulties;

 leaves or other foreign bodies that can obstruct the

exchange batteries;

 winds that hinder or favour the airflow;
 heat or pollution sources close to the unit (chimneys,

extractors etc);

 stratification (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
stratification or recirculation phenomenons.

Ignoring the previous indications could:

 energy efficiency decrease;
 blocks due to HIGH PRESSURE (in summer) or LOW

PRESSURE (in winter).

3.4 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.

With extensive very cold outdoor temperatures, condensation
could freeze and block the flow, causing a slow build-up of
ice; therefore special attention must be paid to eliminating
condensation, raising the unit off the ground and evaluating
whether antifreeze elements should be installed

4.1 PRELIMINARY INFORMATION

Selection and installation of system components must be
carry out by installer.

Following you will find some indications to integrate with what
is provided by the local regulations in force and by the good
technical laws.

4.2 COMPONENTS

CUT-OFF VALVES

 Installed at inlet and outlet (both on the water technique

circuit as well as that of the hot domestic water) allow
maintenance operations without having to empty the
system .

THERMOMETERS AND MANOMETERS

 Installed at entry and exit of the main elements facilitate

inspection and maintenance.

AIR BLEED VALVE

 Installed in all of the highest points of the system allowing

the venting of the circuits air..

DRAINAGE TAPS

 Installed in the lowest points of the system to allow

bleeding.

EXPANSION TANK

 It keeps a correct system pressure when the water

temperature changes. It must be dimensioned as a
function of water plant volume and temperature.

WATER FILTER

 If not present on-board the machine, 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

SUPPORTS

 The hydraulic pipes weight mustn’t burden on the unit

connections ..

FLOW SWITCH

 The flow switch must be present as a component of the

system

4.4 WATER QUALITY

The water quality is determined by the following factors, avoid
therefore:

 Inorganic salts
 pH
 Biological load (seaweeds etc)
 Suspended solids
 Dissolved oxygen

Water with inadequate characteristics can cause:

 pressure drop increase
 energy efficiency decrease
 corrosive symptom increase

4.5 RISK OF FREEZE

If the unit or the relative water connections can be subject to
temperatures close to 0°C adopt measures for prevent risk of
freeze.

For example:

 Mix water with ethylene glycol
 Safeguard the pipes with heating cables placed under the

insulation

 Empty the system in cases of long non-use and check that:

 there are no closed taps present that could trap water

even after emptying

 there are no low points in which water can stagnate

even after emptying; carry out any blowing required .

4.6 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 (pump etc).

Do not use different glicol mixture (i.e. ethylene with
propylene)

4.7 RECOMMENDED CONNECTION

4.3 OPERATION SEQUENCE

1. Carefully wash the system with clean water: fill 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 filter cleaning
interventions and at worst cases can cause damages to the
exchangers and the other parts.

4.8 PARTIAL ENERGY RECOVERY

A configuration which enables the production of hot water free

-of-charge while operating in the cooling mode.

The partial recovery device is considered to be operating
when it is powered by the water flow which is to be heated.

The customer is responsible for the management of the
circulation pump, valves, thermostats, etc.

When the temperature of the water to be heated is particularly
low, it is wise to insert a flow control valve into the system
hydraulic circuit, in order to maintain the temperature at the
recovery output at above 35°C and thus avoid the
condensation of the refrigerant into the partial energy recovery
device.

Water connections must be performed carefully as for the
evaporator (filter, circuit washing, etc).

Perform all necessary interventions to avoid the RISK OF
FREEZING (tubes insulation, emptying of circuit, addition of
glycol, anti-freeze resistances).

Water temperature can reach high temperatures (up to 100°C)
Avoid the RISK OF BURNS by adopting the necessary

precautions (insulation of tubes, temperature detecting station
on water if the sanitary use is foreseen, etc.)

Install safety valves and specifically dimensioned expansion
tanks in the hydraulic circuit.

3. Make sure that all the service outlets are closed with

proper caps; if caps are not present a leak of refrigerant

can be possible.

6.4 HYDRAULIC CIRCUIT

1. Before realizing the unit connection make sure that the

hydraulic system has been cleaned up and the clearing
water has been drained

2. Check that the water circuit has been filled and

pressurized

3. Check that the shut-off valves in the circuit are in the

"OPEN" position.

4. Check that there isn’t air in the circuit, if required,

evacuate it using the air bleed valve placed in the system
high points.

5. When using antifreeze solutions, make sure the glycol

percentage is suitable for the type of use envisaged.

The working out of the limits can cause irreversible damages
and voids the warranty.

6.6 COMPRESSOR CRANKCASE RESISTANCES

Connect the oil resistances on the compressor crankcase at
least 8 hours before the compressor is to be starter :

 at the first unit start-up
 after each prolonged period of inactivity

1. Supply the resistances switching off the unit isolator
switch.

2. To make sure that hte resistances are working, check the
power input .

3. At start-up the compressor crank-case temperature on the
lower side must be higher at least of 10°C than the outside
temperature.

Do not start the compressor with the crankcase oil below
operating temperature.

8 - MAINTENANCE

8.1 GENERAL

Maintenance must be done by authorized centres or by
qualified personnel
The maintenance enables:

 maintain the unit efficiency
 Reduce the deterioration speed to whom every equipment

is subject over time

 Assemble information and data to understand the state of

the unit efficiency and avoid possible damages

8.2 INSPECTIONS FREQUENCY

The inspections should be carried out at least every six months
The frequency, however, depends on the use .

In the event of frequent use it is recommended to plan
inspections at close intervals :

 frequent use (continuous or very intermittent use, near the

operating limits, etc)

 critical use (service necessary) .

8.3 MACHINE BOOKLET

It’s advisable to create a machine booklet to take notes of the

unit interventions.
In this way will be easier marker the various interventions and
will be e facilitate any troubleshooting.

Report on the booklet :

 data
 type of intervention effected
 intervention description
 Carried out measures etc ..

8.4 PUT A REST

If a long period of inactivity is foreseen

 Turn of the power in order to avoid electrical risks or

damages by lightning strike

 avoid the risk of frosts (empty or add glycol in the plant

sections subjected to temperatures below zero , power
antifreeze resistances if are present )

It’s recommended that the starter after the period of detention

is made by a qualified technician, especially after seasonal
stops or seasonal switch.
When restarting, refer to the START-UP section .
Schedule technical assistance in advance to avoid hitches
and be able to use the installation when necessary.

8.6 WATER EXCHANGER

It is very important for the exchanger to be able to provide the
maximum thermal exchange. Therefore, it is essential for the
inner surfaces to be clean of dirt and incrustations.
Periodically check the difference between the temperature of
the supply water and the condensation temperature. If the
difference is greater than 8 °C – 10 ° C it is advisable to clean
the exchanger.
The clearing must be effected :

 With circulation opposite to the usual one
 With a speed at least 1,5 times higher than the nominal one
 With an appropriate product moderately acid (95% water +

5% phosphoric acid

 After the cleaning rince with water to inhibe the detergent

rests.

8.7 ELECTRIC FANS

Check :

 the fans and the relative protection gridsare well fixed
 The fan bearings (evident by noise and anomalous

vibrations )

 the terminal protection covers are closed and the cable

holders are properly positioned

8.8 AIR COIL

Contact with the exchanger fins can cause cuts. Wear
protective gloves to perform the above described operations.
It is extremely important that the battery gives the maximum
thermal exchange; therefore, its surface must be cleaned from
dust and deposits. Remove all impurities from the surface.
It is extremely important that the battery gives the maximum
thermal exchange; therefore, its surface must be cleaned from
dust and deposits. Remove all impurities from the surface.
Using an air pressure gun, clean the aluminum surface of the
battery. Be careful to direct the air in the opposite direction of
the fan air movement.
Hold the gun parallel to the fins to avoid damages. As an
alternative, an aspirator can be used to suck impurities from
the air input side.
Verify that the aluminum fins are not bent or damaged. In the
event of damages, contact the authorized assistance center

and get the battery “ironed out” in order to restore the initial

condition for an optimal air flow

8.9 CIRCULATION PUMPS

8.5 WATER FILTER

Verify that there are no impurities which hinder the smooth
passage of water.

Verify :

 no leaks
 Bearing status (anomalies are highlighted by abnormal

noise and vibration)

 The closing of the terminals cover and the correct

positioning of the cable glands.

or damage to the unit itself.

Check that the installation has been implemented by qualified technical
personnel only and that the instructions contained in the present manual
and the local regulations in force have been adhered to.

The installation of the unit in a place where even infrequent leaks of
inflammable gas and the accumulation of this gas in the area
surrounding the area occur could cause explosions or fires.

Carefully check the positioning of the unit.
The installation of the unit in a place unsuited to support its weight and/

or guarantee adequate anchorage may cause the fall or the tipping of
the unit with the consequent damage to things, people or the unit itself.

Carefully check the positioning and the anchoring of the unit.
Easy access to the unit by children, unauthorised persons or animals

may be the source of accidents, some serious.
Install the unit in areas which are only accessible to authorised person

and/or provide protection against intrusion into the danger zone .
General risks
Smell of burning, smoke or other signals of serious anomalies may

indicate a situation which could cause damage to people, things or the
unit itself.

Electrically isolate the unit (yellow-red isolator).
Contact the authorised service centre to identify and resolve the problem

at the source of the anomaly.
Accidental contact with exchange batteries, compressors, air delivery

tubes or other components may cause injuries and/or burns.
Always wear suitable clothing including protective gloves to work inside

the danger zone.
Maintenance and repair operations carried out by non-qualified

personnel may cause damge to persons, things or the unit itself.
Always contact the qualified assistance centre.
Failing to close the unit panels or failure to check the correct tightening

of all of the panelling fixing screws may cause damage to persons,
things or the unit itself.

Periodically check that all of the panels are correctly closed and fixed.
If there is a fire the temperature of the refrigerant could reach values that

increase the pressure to beyond the safety valve with the consequent
possible projection of the refrigerant itself or explosion of the circuit parts
that remain isolated by the closure of the tap.

Do not remain in the vicinity of the safety valve and never leave the
refrigerating system taps closed.

Electric parts
An incomplete attachment line to the electric network or with incorrectly

sized cables and/or unsuitable protective devices can cause electric
shocks, intoxication, damage to the unit or fires.

Carry out all of the work on the electric system referring to the electric
layout and the present manual ensuring the use of a system thereto
dedicated.

An incorrect fixing of the electric components cover may favour the entry
of dust, water etc inside and may consequently can electric shocks,
damage to the unit or fires.

Always fix the unit cover properly.
When the metallic mass of the unit is under voltage and is not correctly

connected to the earthing system it may be as source of electric shock
and electrocution.

Always pay particular attention to the implementation of the earthing
system connections.

Contact with parts under voltage accessible inside the unit after the
removal of the guards can cause electric shocks, burns and
electrocution.

Open and padlock the general isolator prior to removing the guards and
signal work in progress with the appropriate shield.

Contact with parts that could be under voltage due to the start up of the
unit may cause electric shocks, burns and electrocution.

When voltage is necessary for the circuit open the isolator on the
attachment line of the unit itself, padlock it and display the appropriate
warning shield.

Moving parts
Contact with the transmissions or with the fan aspiration can cause

injuries.
Prior to entering the inside of the unit open the isolater situated on the

connection line of the unit itself, padlock and display the suitable sign.
Contact with the fans can cause incurie.
Prior to removing the protective grill or the fans, open the
display the appropriate warning sign.
Refrigerant
The intervention of the safety valve and the consequent expulsion of the

gas refrigerant may cause injuries and intoxication. Always wear suitable
clothing including protective gloves and eyeglasses for operations inside
the danger zone.

Should the gas refrigerant leak please refer to the refrigerant "Safety
sheet".

Contact between open flames or heat sources with the refrigerant or the
heating of the gas circuit under pressure (e.g. during welding operations)
may cause explosions or fires.

Do not place any heat source inside the danger zone.
The maintenance or repair interventions which include welding must be

carried out with the system off.
Hydraulic parts
Defects in tubing, the attachments or the cut-off parts may cause a leak

or water projection with the consequent damages to peopl, things or
shortcircuit the unit
