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 airow
•
exchange diculties
•
leaves or other foreign bodies that can obstruct the exchange batteries
•
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)
•
positioning below the level of the threshold, close to very high walls, attics or in angles that could give rise to stratication or recirculation
•
phenomenons
Ignoring the previous indications could:
energy eciency 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.

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.

5 Water connections
5.1 Water quality
The water quality can be checked by qualied personnel.
Water with inadequate characteristics can cause:
pressure drop increase
•
energy eciency 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 dierent 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.

7.4 Refrigeration circuit
1. Check carefully the refrigerating circuit: the presence of oil stains can mean leakage caused by transportation, movements or other).
2. Verify that the refrigerating circuit is in pressure: Using the unit manometers, if present, or service manometers.
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.
4. Open the cocks of the refrigerant circuit, if there are any.
7.5 Refrigerant 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 lled and pressurized.
3. Check that the shut-o 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.
Weight of glycol (%) 10 20 30 40
Freezing temperature (°C) -3.9 -8.9 -15.6 -23.4
Safety temperature (°C) -1 -4 -10 -19
7.6 Electric Circuit
Verify that the unit is connected to the ground plant.
Check the conductors tightening: the vibrations caused by handling and transport might cause loosing.
Feed the unit by closing the sectioning device, but leave it on OFF.
Controllare i valori di tensione e frequenza di rete, che devono essere entro i limiti:
400/3/50 +/-10%
•
230/1/50 +/-10%
•
Control the unbalancing of the phases: it must be lower than 2%
Example:
The working out of the limits can cause irreversible damages and voids the warranty.
7.7 Compressor crankcase resistances
Connect the oil resistances on the compressor crankcase at least 8 hours before the compressor is to be starter:
at the rst unit start-up
•
after each prolonged period of inactivity
•
1. Supply the resistances switching o 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.
7.8 Voltages
Check that the air and water temperatures are included in the operating limits.
Start-up the unit.
With operating unit, i.e. in stable conditions and next to the operating ones, check:
