The units have been designed and built according to the current state-of-the-art and technical rules in force regarding
residential water-water heat pumps that exchange heat with the external ground. Applicable laws, provisions, regulations,
decrees and directives to such machinery have been complied with.
The materials used and the parts of equipment, as well as production procedures, quality and control assurance comply with
the highest standards of safety and reliability.
Unit performance, continuous operation and durability are maintained by using the above-mentioned materials and parts
for the purposes specied in this user manual, handling them with due care and performing thorough maintenance and
up-to-standard service.
The MANUFACTURER cannot be held liable for accidents caused when using the unit, due to the user not complying with
laws, provisions, regulations and standards in force regarding uid chillers and heat pumps.
THE MANUFACTURER cannot be held liable in case of malfunctions and damage if the unit:
- is used for purposes other than those intended;
- is not handled and maintained according to the operating rules specied in this manual;
- is not serviced regularly and continuously as prescribed or non-original spare parts are used;
- is either modied or a component is replaced without written authorisation from the MANUFACTURER, especially when
the eciency of the safety systems is intentionally reduced or eliminated;
- is used beyond the ambient temperature limits allowed.
2.2.1 Safety warnings
2.2.2 Accident prevention safety
2.2.3 Operational safety
Personal injury is prevented by not using worn or damaged, low quality or makeshift tools.
Routine maintenance specied in this manual must only be performed by authorised and trained personnel.
Contact the MANUFACTURER for maintenance or repairs not specied in this manual.
Stains of oil and grease and scattered tools or broken parts are hazardous as persons can slip or fall. Always keep the unit
area clean and tidy.
Do not use diesel or petroleum to clean the unit as they leave an oily layer that increases dust adhesion, and neither solvents
must be used (even if weak) as they damage the paint and increase the formation of rust.
If a jet of water penetrates the electrical equipment the contacts oxidise and the unit may malfunction.
Therefore, do not use jets of water or steam on the sensors, connectors or any electrical part.

Many accidents and damage are due to maintenance errors, such as:
- lack of water in the circuit;
- incorrect percentage of refrigerant in the circuit;
- inadequate refrigerant;
- failure to keep the unit area clean;
- circuit ineciency (pipe connections, loose pipes, screws, etc.).
Maintenance must be performed carefully even for personal safety.
Never delay repairs.
Only specialised or authorised personnel must perform repairs.
Always comply with the following safety standards, even when you are completely familiar with all the operating elements:
- Always keep the unit and its surrounding area clean.
- Before starting work check that the safety devices are in perfect working condition.
- Make sure that no unqualied or unauthorised persons enter the unit area.
2.3.4 Care and maintenance
3 - DESCRIPTION OF THE PRODUCT AND TECHNICAL DATA
3.1 THE SERIES
3.1.1 Identication of the unit
HHP is a multi-purpose air-water heat pump that, by exchanging heat with the outside air, and with no combustion or ame,
warms, cools and produces domestic hot water in a fully autonomous way, as a priority.
During winter and autumn operation it heats the room or produces domestic hot water. The inertia of the system, increased
by the storage tank, which we recommend combining with the machine even on the heating system, also enables the
priority production of domestic hot water without discomfort.
During summer operation it cools the water for air conditioning purposes and, if necessary, dehumidies the rooms and
produces hot water as an alternative priority to cooling.
Here are the features shared by the units of the series:
• Split unit with compressor mounted in the indoor unit so as to reduce the emission of sound outdoors and to have
a lightweight outdoor unit that can be positioned at a height with simple brackets, or an outdoor unit running from
indoors, ductable, compact with reverse blade fans driven by a synchronous EC motor with permanent magnets.
• EEV (electronic expansion valve) to benet from the possibility of generating thermodynamic cycles with reduced
pressure surges and therefore signicant COP advantages.
• Integrated controller of the pump on the system circuit and DHW circuit: the pump is managed directly by the unit.
• AISI 316 stainless steel brazed high-eciency plate heat exchangers.
• Advanced electronic control to adequately address the needs of capacity control of loads for optimal operation of partial
loads, increasingly the subject of evaluation and discerning technical choices by heat engineering designers.
• Scroll or twin-rotary compressors, both with BLDC inverter
Dual hydraulic circuit:
• Air conditioning circuit with reversible cooling circuit side and variable set-point between min/max with potential-free
contact or with 0-10V or 4-20mA signal.
• DHW circuit managed with a 3-way valve installed inside the unit

HF61GJ0181C
The structure of the HHP series units has the following features:
• Indoor unit: side panelling in galvanised sheet metal painted with polyester epoxy powders and polymerised in the
oven at 180°C and a front cover with a built-in display. The unit is fully panelled, but can be accessed on 3 sides since the
panels can easily be removed, thus simplifying maintenance and/or inspections. All routine maintenance is performed
from the front of the machine.
• Outdoor unit: side panelling in galvanised sheet metal painted with polyester powders and polymerised in the oven
at 180°C. The unit is entirely faired, panelled and available in RAL9002. Axial 6-pole fans, with high degree coverage of
blades, combined with asynchronous motors with external rotor (or synchronous motors with permanent magnets) and
constant modulation of the rotation speed.
• Remote unit for indoor installation: panelling in galvanised sheet metal painted with polyester powders and polymerised
in the oven at 180°C. The unit is entirely faired and is available in RAL9002. Radial fans with brushless motors are used,
which are ideal for continuous and ecient modulation.
The components are distributed to guarantee easy access and the layout ensures optimum weight distribution on the unit’s
base.
