The lubricating oil used in the cooling circuit of the unit is of the polyester type. In any case, always refer to what is indicated on the compressor
plate.
For any further information regarding the characteristics of the refrigerating fluid and oil used, refer to the safety data sheets
available from the manufacturers of refrigerant and lubricating oils.
ENVIRONMENTAL PROTECTION: Carefully read the ecological information and the following instructions.
Users and maintenance personnel must be adequately informed about the risks due to the handling of potentially toxic
substances. Failure to observe the above instructions may cause personal injury or damage the unit.
Main Ecological Information on the refrigerants used.
2.1.3 Persistence and degradation
The refrigerating fluids used decompose in the lower atmosphere (troposphere) relatively quickly.The decomposed products are highly dispersible
and therefore have a very low concentration. They have no influence on photochemical smog, meaning that they are not one of the VOC volatile
organic compounds (as established by the guidelines of the UNECE agreement). R410A refrigerants (R32 and R125) do not damage the ozone
layer. These substances are regulated by the Montreal protocol (1992 revision) and by EC regulation no. 2037/200 dated 29 June 2000.

Discharges into the atmosphere of these products do not cause long-term water contamination.
2.1.5 Exposure control and individual protection
Use protective clothing and gloves; always protect the eyes and face.
2.1.6 Occupational exposure limits
HFC-32 TWA 1000 ppm
HFC-125 TWA 1000 ppm
2.2 HANDLING
2.3 PREVENT THE INHALATION OF HIGH VAPOUR CONCENTRATIONS
Atmospheric concentrations of refrigerant must be kept to a minimum and kept as low as possible, below the occupational exposure limit.
Vapours are heavier than air, and dangerous concentrations can form near the ground, where general ventilation is poor. In this case, ensure
adequate ventilation. Avoid contact with naked flames and hot surfaces, because toxic and irritating decomposition products can be formed.
Avoid contact between the liquid and the eyes or skin.
2.4 PROCEDURES IN CASE OF ACCIDENTAL REFRIGERANT LEAKAGE
Ensure adequate personal protection (using means of respiratory protection) during cleaning operations.
If the conditions are sufficiently safe, isolate the source of the leak. If the amount of the leak is limited, allow the material to evaporate provided
that adequate ventilation is ensured. If the leak is significant, adequately ventilate the area.
Contain spilled material with sand, earth or other suitable absorbent material.
Prevent the refrigerant from entering drains, sewers, basements or work holes, because suffocating vapours can form.

2SAFETY
Strictly follow the warnings and first aid procedures below.
2.5 MAIN TOXICOLOGICAL INFORMATION ON THE TYPE OF REFRIGERANT USED
2.5.1 Inhalation
A high atmospheric concentration can cause anaesthetic effects with possible loss of consciousness.
Prolonged exposures can cause abnormal heart rhythms and sudden death.
Higher concentrations can cause asphyxia due to the reduced oxygen content in the atmosphere.
2.5.2 Contact with the skin
Splashes of sprayed liquid can cause frost burns. It is unlikely to be dangerous due to skin absorption.
Prolonged or repeated contact may cause removal of skin fat, resulting in dryness, cracking and dermatitis.
2.5.3 Eye contact
Splashes of sprayed liquid can cause frost burns.
2.5.4 Ingestion
Although highly unlikely, it can cause frost burns.
2.6 FIRST AID MEASURES
2.6.1 Inhalation
Remove the victim from the source of exposure, keep them warm and at rest. Administer oxygen if necessary. Give artificial respiration if
breathing has stopped or shows signs of stopping. If there is cardiac arrest perform external cardiac massage. Request medical assistance.
2.6.2 Contact with the skin
In case of contact with the skin, wash immediately with warm water. Thaw the epidermal tissue with water. Remove contaminated clothing.
Clothing can stick to the skin in case of frost burns. If there is irritation or blistering, seek medical assistance.
2.6.3 Eye contact
Wash immediately with eye wash or with clean water, keep eyelids open for at least ten minutes.
Request medical assistance.
2.6.4 Ingestion
Do not induce vomiting. If the injured person is conscious, rinse the mouth with water and administer 200-300 ml of water to be drunk.

3 TECHNICAL SPECIFICATIONS
3.1 UNIT DESCRIPTION
The series heat pumps are particularly suitable for use in groundwater or geothermal probes. These units find their ideal application in
combination with radiant panel heating systems or in all situations in which maximum efficiency is required in heating mode. The units have
been designed to have an extremely efficient heating performance and can operate with a water temperature of up to 60°C.
The units are available in various versions both in the 2-pipe configuration on the utility side and in the 4-pipe configuration on the utility
side. All versions are able to produce domestic hot water; the 2-pipe versions through the activation of an external 3-way valve, the 4-pipe
versions using a dedicated hydraulic circuit used for domestic hot water which allows its production regardless of the unit's operating mode.
The available versions and the wide range of accessories make it possible to identify the model and the most suitable solution for the type of
system served.
3.1.1 Carpentry
All units are produced in hot-dip galvanised sheet metal and painted with polyurethane powders in the oven at 180°C to ensure the best
resistance to atmospheric agents. The carpentry is self-supporting with removable panels to facilitate inspection and maintenance of the internal
components.
3.1.2 Cooling circuit
The refrigerant gas used in these units is R410A. The refrigeration circuit is created using components from leading international companies and
according to the regulations concerning the brazing and welding processes.
The cooling circuit includes: filter drier, electronic thermostatic valve, cycle reversing valve, Schrader valves for maintenance and control and
a safety device (according to the PED regulation).
3.1.3 Compressor
The compressors are of the scroll type, optimised for heating applications with a particular structure that offers high efficiencies especially when
the source temperature is low. The compressors are supplied with a thermal protection relay embedded in the electric windings. Inspection of
the compressors is possible through the front panel of the unit which allows maintenance even with the units in operation.
3.1.4 Source exchanger
The source side exchangers, with braze-welded plates, are made of AISI 316 stainless steel. They are of the single circuit type. Use of this type of
heat exchangers greatly reduces the refrigerant charge of the unit compared to traditional shell and tube evaporators, and increases its cooling
capacity. The exchangers are insulated in the factory using closed cell material and are protected by a temperature probe used as an antifreeze
protection probe.
3.1.6 Utility exchangers
The utility side exchangers are made of braze welded plates and AISI 316 stainless steel. They are of the single circuit type. All units are equipped
with a "sub-cooler" to increase the efficiency of the refrigeration cycle. The exchangers are insulated in the factory using closed cell material.
3.1.7 Electrical panel
The electrical panel is made in compliance with the European standards EN60204. Access to the electrical panel is possible by removing the
front panel of the panel, being sure to position the main door interlock switch in the OFF position. The following components are also present
as standard: Main switch, thermomagnetic circuit breakers to protect the compressors and fuses to protect the pumps and auxiliary circuits,
compressor relay and pump relay. The panel is also equipped with a terminal board with a configurable digital input and voltage-free digital
outputs.
3.1.8 Microprocessor
All units are equipped with microprocessor control. The microprocessor controls the following functions: water temperature regulation,
antifreeze protection, compressor timing, compressor start-up sequence, alarm reset, alarm management and operation LED. On request the
microprocessor can be connected to remote BMS control systems. The technical office is available to study, together with the customer, different
solutions using the most popular communication protocols.
3.1.9 Control and Protection Devices
All the units are supplied as standard with the following control and protection devices: supply water temperature probes on source side
heat exchanger and on utility side heat exchanger, manual reset high pressure switch, compressor uniperometric protection, pump thermal
protection, high and low pressure transducers, source circuit and utility circuit differential pressure switch.
3.1.10 Hydraulic kit
The HFE series units are equipped with a hydraulic kit consisting of the following:
• utility circuit: variable speed circulation pump, expansion vessel (on some models), water flow sensor (differential pressure switch),
connection for filling and draining water;
• source circuit: variable speed circulation pump (or modulating two-way valve, for the well version) regulated by the microprocessor
to optimise the operating conditions of the cooling circuit, expansion vessel (on some models), water flow sensor (pressure switch
differential for the probe and flow switch version - to be installed on site - for the well version), connection for filling and draining
water;
• sanitary circuit (for the R version): variable speed circulation pump regulated by the microprocessor to maximise the recovery of
condensation heat.
The HFS series units are not equipped with the components described above which, however, can be installed on the system and managed by
the unit's microprocessor. The units include a flow sensor (flow switch) on the utility exchanger and on the source one.
Rev. C 09-2020MTEC.3810.GB-C-1 Operation and maintenance manual serie WZA English

The units are equipped with a hydraulic kit consisting of the following:

3TECHNICAL SPECIFICATIONS
3.1.11 Electronic thermostatic valve
All the units are equipped with an electronic thermostatic valve, in order to optimise the functioning of the cooling circuit and to maximise the
energy efficiency of the system in all operating conditions that can be implemented on the system.
3.2 VERSIONS AVAILABLE
All units are hot/cold reversible, with cycle inversion on the cooling circuit.
3.2.1 Version (without heat recovery)
The units in this version are equipped with a single heat exchanger on the utility side to produce hot water in heating operation or chilled water
in cooling operation (the two operating modes are alternatives to each other). The unit must be installed on a "two-pipe" type system.
3.2.2 Version with domestic hot water diverter valve management
The units in the version without heat recovery can be configured to manage a diverter valve to heat a storage tank to be used for the production
of domestic hot water. In this way, in each of the operating modes described above, if the temperature in the domestic hot water storage tank
falls below a selected value, the unit will be set up to bring it back to the determined set value, positioning the diverter valve appropriately. This
operating mode is a priority and an alternative to operation for the utility (in heating or cooling).
The unit must be installed on a "two-pipe" type system; a three-way diverter valve (not included in the machine) must be installed on the unit's
outlet connection for heating of the domestic hot water storage tank.
The configuration of the control to manage the diverter valve should be performed in the factory and as such it is necessary to communicate
this requirement during the order phase.
3.2.3 Version /P4S (with total heat recovery)
The units in the version with total heat recovery, in addition to the one on the utility side, are equipped with an additional heat exchanger
dedicated to domestic hot water heating. This exchanger is installed on the compressor discharge line, upstream of the cycle reversing valve,
through which the high pressure and temperature refrigerant passes both in heating and in cooling operation; this exchanger is sized in such a
way as to completely dissipate the condensation heat of the refrigeration circuit.
Thanks to this component, the units in version /R can perform all the functions described in the previous paragraph, but with some considerable
advantages. Firstly, if the conditions exist to do this, it is possible to transfer to the storage of heat recovered by the domestic hot water exchanger
while the unit is operating in heating or cooling mode. Furthermore, when switching from cooling to domestic hot water operation or vice-versa,
there will be no mixing of water at different temperatures between the utility circuit and the sanitary circuit, as in the case of the diverter valve.
The unit must be installed on a "four-pipe" type system (two for the utility circuit and two for the domestic hot water circuit - in this case, the
two circuits are completely separate). If the temperature in the domestic hot water storage tank falls below a selected value, the unit will be set
to return it to the determined set value, transferring heat through the dedicated exchanger. In heating mode, if the necessary conditions exist,
the unit will simultaneously transfer high-temperature heat to the domestic water storage and heat to a temperature below the utility circuit; in
this case, the advantage is to transfer the share of heat at high temperature to an efficiency comparable with that of low temperature heating. In
cooling mode, if the necessary conditions exist, the unit will extract heat from the utility circuit and transfer it, as far as possible, to the sanitary
circuit, disposing of the remainder in the source; in this case the heat transferred to the sanitary circuit is produced completely free, as, if it were
not recovered, it would be dissipated in source.
In both cases, the heat recovery mechanism can occur even if the temperature in the domestic hot water storage has reached the set point; this
is why it is not uncommon for the domestic hot water storage to be found at temperatures above the set temperature.
The sanitary exchanger circuit must be created by providing an expansion vessel, a safety valve, a filling and discharge connection (not included
in the unit).

The nominal water flow refers to a temperature difference between input and output of the utility exchanger of 5°C. The maximum permissible
flow rate is the one with a temperature difference of 3°C. Higher values can cause overly high pressure drops.
The minimum permitted water flow is the one with a temperature difference of 8°C.
Insufficient water flow rates can cause abnormal operating temperatures in the cooling circuit resulting in intervention of the safety devices and
the unit stopping.
3.5.2 Utility hot water temperature (winter operation)
Once the system is fully operational, the temperature at the entrance to the utility and/or domestic hot water exchanger must not fall below
30°C; lower values can cause compressor malfunctions with the possibility of breakage.
The maximum outlet water temperature of the utility exchanger must not exceed 65°C from size 06 to 40 and 60°C from 60 to 100. Otherwise
the action of the safety devices stops the unit.
3.5.3 Chilled water temperature (summer operation)
The minimum temperature permitted at the utility heat exchanger outlet is 5°C; it is possible to produce water up to -5°C by adding an adequate
quantity of glycol in the utility circuit. For lower temperatures the unit requires structural changes. In this case, contact our technical department.
The maximum water temperature produced is 18°C.
3.5.4 Source water temperature
The minimum water outlet temperature from the source side exchanger (with glycoled water), in heating mode, is -20°C for sizes from 06 to 40
and -10°C for sizes from 60 to 100.
The appliances, in their standard configuration, are not suitable for installations in a saline environment.
The units are built according to the technical standards and safety rules in force in the European Community. The units
have been exclusively designed for heating, air conditioning and domestic hot water (DHW) production and must be
used for this purpose, compatibly with their performance characteristics. Any contractual or non-contractual liability of
the Company is excluded for damage caused to persons, animals or property, installation errors, adjustment and mainte-
nance or for improper use. All uses not expressly indicated in this manual are not permitted.
In case of operations outside of these values, please contact the Company.

The correction factors of the water flow rate and the pressure drops must be applied to the values obtained without the use of glycol. The
water flow rate correction factor is calculated in such a way as to maintain the same temperature difference that would be obtained without
the use of glycol. The pressure drops correction factor is applied to the correct water flow value of the water flow correction factor.
