1. INTRODUCTION
2. OPERATION LIMITS
• 30PA/PAC
Air-cooled water chillers.
• 30PH/PHC
Reversible heat pump units for operation in negative outdoor
temperatures (greater than -15ºC WB) for water heating and cooling.
Defrosting by reversing the cycle.
After manufacturing, all units are charged with refrigerant and
are tested at the factory, verifying the correct operation of all their
components within the operating range for which they are intended.
The units comply with European Directives: Machinery 2006/42/EC -
EMC 2014/30/EU - LVD 2014/35/EU - PED 2014/68/EC (Category 2)
- RoHS 2011/65/EU - Eco-design 2009/125/CE - Eco-labelling 2010/30/
EU; and with Harmonised Standard: EN 378-2:2012.
Those in charge of the installation, commissioning, operation and
maintenance of the unit must know the instructions contained in this
brochure and the specific technical characteristics of the installation place.
The 30PA/PH cooling only and reversible heat pumps are compact
outdoor air/water units.
Available in two versions:
• STD (Standard)
• HEE (High Energy Effi ciency)
These units have been made for operation indoors in the production
of hot and/or cold water, applicable to heating, cooling, and industry.
They are equipped with centrifugal fan (STD version) or electronic plug-
fan (HEE version), plate exchanger, hermetic scroll compressor, and
electronic control with microprocessor, components optimised for the
R-410A refrigerant.
This range is also offered with an integrated circulation pump:
30PAC/PHC.
The entire range also has the option to include a desuperheater circuit
that allows for the production of hot water at a temperature greater than
in the condensation circuits.

4. AVAILABLE CONFIGURATIONS
According to the air supply:
• Assembly M00
HORIZONTAL air supply.
• Assembly M01
VERTICAL air supply.
According to the type of supply fan:
• STD version (Standard):
Centrifugal fan coupling by pulleys and belts.
• HEE version (High Energy Effi ciency):
Variable speed electronic plug-fan.
M00 M01 STD HEE
These units work with refrigerant gas R-410A.
3. SAFETY ADVICE
To avoid any risk of accident during installation, commissioning or
maintenance, it is obligatory to take into consideration the following
specifications for the units: refrigerated circuits under pressure, refrigerant
presence, electrical voltage presence and implantation place.
Because of all of this, only qualified and experienced personnel can
perform maintenance tasks or unit repairs.
It is required to follow the recommendations and instructions
in the maintenance brochures, the labels, and the specific
instructions.
It is necessary to comply with the norms and regulations
in effect. It is recommended to consult the competent
authorities regarding the applicable regulations for users
of units or components under pressure. The characteristics
of these units or components are included on the plates of
characteristics or in the regulatory documentation provided
with the product.
In case of a leak:
- Toxicity: According to ASHRAE 34, R-410A belongs to the A1/A1 group,
i.e. with high safety both in the mix and also in the case of a leak.
- Although it is not toxic, in case of a leak to atmospheric pressure the
liquid phase evaporates. The resulting vapours are heavier than air
and can displace the technician local air. In case of an accidental
discharge in a closed enclosure, fans must be used to eliminate said
vapours.
- Although the R-410A is not flammable, when in contact with a flame
o hot spot it can decompose in fluorhydric acid HF and fluophosgene
COF2highly toxic and corrosive.
- To detect leaks, an electronic leak detector, an ultraviolet lamp or
soapy water must be used. Flame detectors do not help.
Important: Immediately repair any refrigerant leak, using
a recovery unit specific for R-410A that avoids a possible
mixture of refrigerants and/or oils.
The compressor and line surfaces can reach temperatures
above 100ºC causing burns to the body. In the same fashion,
under certain conditions these surfaces can reach very cold
temperatures that can cause freezing risks.
Use safety goggles and gloves on the job. Be careful with
sharp parts or elements in the unit.
V-220005
V-220004
Caution: Before intervening in the unit, verify that the main
power to the unit is cut off. An electric shock can cause
personal damage.
Refrigerant leaks:
A periodical check must be performed for refrigerant gas leaks as
per Regulation (CE) Nº517/2014 over certain greenhouse effect
fluoride gases. Please, consult the frequency of checks in chapter
of “Maintenance”.

7. TRANSPORT AND HANDLING
Centre of gravity coordinates
- Discharge via forklift truck:
The unit is designed to be transported safely by using a forklift truck.
The forks of the forklift truck must come in on the side of the unit,
ensuring that the centre of gravity of the unit remains within the forks,
because a misbalance in the transport may cause the unit to turn
over and fall from the forklift truck.
The recommended length for the forks will be bigger than the unit
width, so that the entire weight-bearing structure can be supported
on the forklift truck. This also prevents the possible introduction
of the truck’s fork into functional parts of the unit that may cause
damage to the unit.
The standards and recommendations of the forklift truck must also
be respected with regards to the maximum load, inclination of the
panel, elevation of the load for transport, and, in particular, the
maximum speed.
Transport
The unit must be handled with care to avoid transport damage. Thus
we recommend:
- Do not dispose of the transport supports or the packaging materials
until the unit is in its final location.
- For transport in a container, one must be selected that has an easy
load and unload to the installation location.
Discharging of the unit
The unit can be discharged using:
- Forklift truck.
- Crane with a rocker arm and cloth slings.
Any handling of the unit by other means or by gripping points different
from those described here may be dangerous for both the unit and
the personnel who are carrying out the discharging or transport work.
Always check the weight of the set and verify that the discharging
method used is approved for handling that weight.
Note: please see the weight and the gravity centre coordinates
of each model stated in the following section.
Placement on site
Once the unit is discharged, it must be freed from the transport supports
so that the inserts available for the silent-blocks can be accessed. Each
support is fixed to the crossbar using 2 M4 screws.
M4 screws for fixing the support Mounting hole
- Discharge via crane:
A rocker arm, as well as approved cloth slings, both suitable for the
dimensions and weight of the unit, must be used in order to carry out
the work safely and without causing damage to the units or to workers.
These slings will be hooked
to the two mounting holes
located on each crossbar. Make
sure that the unit is protected
from contact with the hooks to
prevent damage to the housing.
The unit must be lifted and fixed with care, with maximum
inclination of 15º, since it could harm its operation. Do not
raise by points outside of those specified here.
