GENERAL FEATURES
1. GENERAL FEATURES
1.1 Presentation of the system
> GENERAL CHARACTERISTICS:
• The family of OMNIA HYBRID C hybrid heat pumps integrates the technology of the heat pump and the condensing boiler with instantaneous dhw production in
a single compact product.
• This represents the ideal solution for replacing old existing boilers, also on high temperature system with radiators.
• The compact dimensions, similar to those of a wall-hung boiler, make it easier to replace without losing significant space or requiring significant restructuring work.
• Internal electronics, by running the boiler or the heat pump as the climatic conditions vary, optimise the output of the system by always working in the most economic consumption-related modes possible.
• During heat pump operation in heating or conditioning mode, the boiler can produce dhw at the same time without interfering on heat pump operation, thereby
maximising the comfort of both services.
• If the heat pump is partially or fully blocked, the boiler can operate separately in heating and dhw production.
• it is composed of an external inverter unit available in 3 power sizes associated with an internal condensation unit with integrated hydronic module for cooling
circuit control.
• A highly versatile system that can operate in particularly cold climatic conditions (outdoor air down to -20°C).
• The split cooling circuit avoids the risk of freezing in particularly cold outdoor applications.
• The user interface is composed of a digital remote controller equipped with a large display and simple setting controls.
• Wall flue gas exhaust in cases pertaining to Lgs.D. 4 July 2014, No. 102.
> CHARACTERISTICS OF EXTERNAL UNIT:
• Approved for outdoor operation in completely exposed site.
• Breakaway starting current thanks to Inverter technology.
• Compressor with twin rotary DC INVERTER motor on vibration damping supports and wrapped in double layer of soundproofing material to reduce vibrations and
noise to a minimum.
• The compressor is also equipped with casing oil heating element.
• Two-flow electronic expansion valve, cycle inversion valve.
• Axial fans with brushless DC motor complete with protective grids.
• Outdoor air temperature probe already installed on the unit.
> CHARACTERISTICS OF INTERNAL UNIT:
• A particularly sturdy boiler, suitable for replacements even in particularly critical and resistant systems.
• Combustion module with high modulation range (1:10) with high thickness stainless steel primary exchanger, with larger passes maintaining high efficiency even
on old systems with oxidation and soiling
• M.G.R: Methane, LPG, Propane air Ready, with a simple configuration the internal unit can run on methane, lpg and propane-air without the use of any additional
conversion kits.
• MC2: Multi Combustion Control, combustion system with gas-adaptive patented technology for better adaptability of use to the varying gas network conditions
(ex. pressure fluctuations or drops)
• F.P.S: Flue gas Protection System. The standard flue gas check valve offers easy connection to pressurised collective flue systems
• Particularly suitable for operation in flues requiring “heavy duty” pipes thanks to approval for operation with flue gas exhaust with a diameter of 50mm.
• Can be combined with preheating systems for the domestic hot water.
• Place of installation: also for outdoor use in a partially protected place that is up to -5°C, as standard
• Free methane/LPG/Propane-air conversion at the time of product testing and warranty activation, by the Authorised Assistance Centre

1.5 Remote control
The user interface consists of a wired remote controller (up to 50 m from the unit)
which allows the management of:
- HEATING AND COOLING SYSTEM. The unit, if activated in heat or cool mode,
works by modulating the frequency of the compressor to maintain the temperature
of the produced water to the setpoint value set by the controller. Through parameter you can use the remote controller (eg. For single-zone systems) as a room
thermostat.
- HEATING WITH BOILER. As a function of the set parameters, can be activeted
in integration or substitution of the heat pump. The electronic board will activate
the boiler in case the heat pump does not work.
- SILENCED MODE: according to a programmed schedule, this reduces the maximum frequency of the compressor and the fan speed, to reduce the generated
noise and the power absorbed by the unit.
- ON / OFF using an external contact. The unit can be turned on and off (eg. thermostat / remote switch) via an external contact: in this case the unit will operate in
the mode set by the controller keyboard.
- HEAT / COOL via external contacts. The unit can be activated in heat or cool
mode via two external contacts (eg. thermostat that manages the heat and cool
demand / remote switch).
- ECO MODE: possibility of defining a time slot in hot mode where the heat pump
runs with a sliding setpoint defined by the chosen climatic curve. There are 8 climatic curves for low temperature systems (radiant floor) and 8 climatic curves for
fan coil or radiator systems).
- WEEKLY PROGRAMMING: this makes it possible to set a different schedule for
each day of the week defining the operating mode for each time slot (COLD/HOT)
and the work setpoint.

INSTALLATION
■ Prepare a water drainage channel around the foundation, to drain waste water
from around the unit.
■ If water does not easily drain from the unit, mount the unit on a foundation of
concrete blocks, etc. (the height of the foundation should be about 100 mm.
■ If you install the unit on a frame, please install a waterproof plate (about 100
mm) on the underside of the unit to prevent water from coming in from the low side.
■ When installing the unit in a place frequently exposed to snow, pay special
attention to elevate the foundation as high as possible.
■ In heavy snowfall areas it is very important to select an installation site where
the snow will not affect the unit. If lateral snowfall is possible, make sure that the
heat exchanger coil is not affected by the snow (if necessary construct a lateral
canopy).
■ As the outdoor temperature is measured via the outdoor unit air thermistor,
make sure to install the outdoor unit in the shade, or a canopy should be constracted to avoid direct sunlight, so that it is not influenced by the sun’s heat,
otherwise protection may be possible to the unit.
■ Check the strength and level of the installation ground so that the unit will not
cause any operating vibration or noise after installation.
■ In accordance with the foundation drawing in the figure, fix the unit securely by
means of the foundation bolts. (Prepare four sets each of Ø10 Expansion bolts,
nuts and washers which are readily available on the market.)
■ It is best to screw in the foundation bolts until their length is 20 mm from the
foundation surface.
When installing the unit in a place exposed to strong wind, pay special attention
to the following.
Set the outlet side at a right angle to the direction of the wind.
Strong winds of >5 m/s or more blowing against the unit’s air outlet causes a short
circuit (suction of discharge air), and this may have the following consequences:
- Deterioration of the operational capacity.
- Frequent frost acceleration in heating operation.
- Disruption of operation due to rise of high pressure.
- When a strong wind blows continuously on the front of the unit, the fan can start
rotating very fast until it breaks.

6.5 Limits to the length and heigth difference of refrigerant pipes
The length of the refrigerant pipes between the indoor and outdoor units must be as short as possible and is in any case limited by compliance with the maximum
height difference values between the units.
Diminution of the difference in height between the units (H1,H2) and of the pipe lengths (L) will limit the load losses, consequently increasing the overall efficiency of
the machine.

6.10 Tightness check (recommended operation)
Before setting the system in a vacuum, it is advisable to make sure that the cooling
circuit is tight, including the connecting joints between the pipes and the indoor
unit. Proceed in the following way:
• With the service valves of the outdoor unit completely shut, remove the cap
from the service tap (1- side figure) of the gas connection (the larger one)
• Connect the service valve to a monometric unit plus nitrogen bottle (N2).
• Pressurize the system to a maximum 30 bar using the nitrogen in the bottle.
• Use liquid soap to check that the joints are tight.
Keep the bottle vertical during the pressurizing operation to prevent liquid nitrogen
from infiltrating into the system!
• Check all the connection joints on both the outdoor and indoor units to make
sure that they are tight. Bubbles will form if leaks are present. If bubbles
appear, make sure that the unions have been tightened and that the flares
are the right shape.
• Wipe off the liquid soap with a rag.
• Reduce the pressure of the nitrogen in the circuit by loosening the charge
pipe from the bottle.
• Having reduced the pressure, disconnect the nitrogen bottle.

6.11 Vacuum operation (obligatory)
ir and humidity in the cooling circuit impair the operation of the unit with effects
such as:
• Increased pressure.
• Reduced efficiency.
• Formation of ice on the capillary and subsequent blockage of the same.
• Corrosion in the circuit.
This is why a vacuum must be created in the connection pipes and indoor unit.
Proceed in the following way:
U.E.
• Connect the previously described charging pipe to the vacuum pump.
• Turn on the relative knob on the monometric unit to allow the pump to access
the cooling circuit.
• Wait until the pressure level measured by the pressure gauge is around 3 mm
Hg (400 Pa)
• As soon as the required vacuum value is reached, shut the connection cock and
stop the vacuum pump.

NOTA
■ To activate the system it is necessary to open both the liquid and gas shut-off valves of the outdoor unit: remove the caps from both valves, and then open the valves
with an Allen wrench.
■ It is advisable to open the valves when the installation of the system is complete from an electric and hydraulic point of view and it is therefore possible
to proceed with the first start-up.
6.12 Indoor unit hydraulic connections
U.I.
The safety valve outlet must be connected to a funnel or collection pipe to prevent water spurting onto the floor in case
of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and floods the room, the boiler manufacturer
cannot be held liable.
Before installation, flush all the pipes of the system thoroughly to remove any residuals or impurities that could affect
proper operation of the unit.
In case of replacement of generators in existing installations, the system must be completely emptied and cleaned of any
sludge and pollutants. For that purpose only use suitable guaranteed products for heating systems (see next section), that
do not harm metals, plastics or rubber.
The manufacturer declines any liability for damage caused to the generator by failure to properly clean the system.
Since the joints of the unit are made of brass and brass is an easily deformable material, using appropriate
tools for connecting the hydraulic circuit, inappropriate tools will cause damage to the pipes.
Make the connections to the respective points (see “fig. 6 - dimensional data and connections” on page 11) and to the symbols given on the unit.

Cod. 3541T090 - Rev. 00 - 06/2019
INSTALLATION
Antifreeze system, antifreeze fluids, additives and inhibitors
When necessary, antifreeze fluids, additives and inhibitors can be used only if the manufacturer of such fluids or additives guarantees that they are suitable and do not
cause damage to the exchanger or other components and/or materials of the boiler/heat pump and system. Do not use generic antifreeze fluids, additives or inhibitors
that are not specific for use in heating systems and compatible with the materials of the boiler/heat pump and system.
System water characteristics
The heat pumps are suitable for installation in heating systems with non-significant entry of oxygen (ref. systems “case
I” EN14868). A physical separator (e.g. plate heat exchanger) must be provided in systems with continuous entry of oxygen
(e.g. underfloor systems without antidiffusion pipes or open vessel), or intermittent (less than 20% of system water content).
The water within a heating system must have the characteristics required by UNI 8065, and comply with laws and regulations
in force and the provisions of EN14868 (protection of metallic materials against corrosion).
The filling water (first filling and subsequent replenishment) must be clear, with hardness below 15°F and treated with suitable
chemical conditioners against the initiation of corrosion, that are not aggressive on metals and plastics, do not develop gases
and, in low-temperature systems, do not cause proliferation of bacterial or microbial masses.
The water in the system must be periodically checked (at least twice a year during the season when the systems are used,
as required by UNI8065) and have: possibly a clear appearance, hardness below 15°F for new systems or 20°F for existing
systems, pH above 7 and below 8.5, iron content (Fe) below 0.5 mg/l, copper content (Cu) below 0.1 mg/l, chloride content
below 50mg/l, electrical conductivity below 200 µs/cm, and must contain chemical conditioners in a concentration sufficient
to protect the system for at least one year. Bacterial or microbial loads must not be present in low temperature systems.
Only use conditioners, additives, inhibitors and antifreeze liquids declared by the producer suitable for use in heating systems
and that do not cause damage to the heat exchanger or other components and/or materials of the boiler and system.
Chemical conditioners must ensure complete deoxygenation of the water, contain specific protection for yellow metals (copper and its alloys), anti-fouling agents for scale, neutral pH stabilizers and, in low-temperature systems, specific biocides for
use in heating systems.
Recommended chemical conditioners:
SENTINEL X100 and SENTINEL X200
FERNOX F1 and FERNOX F3
The unit is equipped with a frost protection system that activates the heat pump in heating mode when the system delivery
water temperature falls below 4°C. The device is not active if the power and/or gas supply to the unit is turned off. If necessary, for system protection use a suitable antifreeze liquid that meets the same requirements as set out above and provided
for by Standard UNI 8065.
In the presence of adequate chemical/physical system and feed water treatments and related high cyclicity controls able to
ensure the required parameters, for industrial process applications the product can be installed in open-vessel systems with
vessel hydrostatic height able to ensure compliance with the minimum operating pressure indicated in the product technical
specifications.
The presence of deposits on the indoor unit exchange surfaces due to non-compliance with the above requirements
will involve non-recognition of the warranty.
Water filter
A water filter must be installed at the entrance of the unit.
The unit is supplied as standard with two square taps. The tap with a blue handle is equipped with a filter (which can be disassembled by unscrewing the rear fitting)
and therefore acts as an interception tap and a water filter; this tap must be mounted on the system return connection (see part.10 “fig. 6 - dimensional data and
connections” on page 11). The tap with red handle must be mounted on the system delivery connection (see part 11 “fig. 6 - dimensional data and connections” on
page 11).

INSTALLATION
Tips for a successful installation
For a correct design and installation of the hydraulic plant comply the local laws governing safety matters and sound.
The following information is suggestion for a correct installation of the unit.
• Before connecting the unit to the system wash adequately the pipes using clean water, filling and emptying and cleaning the filters.
• Only after that proceed connecting the unit to the system; this operation is crucial to ensure proper start-up without the need to have repeated stops to clean the
filter, with the possible risk of damage to heat exchangers and other components.
• Check by qualified personnel the quality of the water or of the mixture used; avoid the presence of inorganic salts, biological load (seaweeds, etc.) suspended
solids, dissolved oxygen and the pH. Water with inadequate characteristics can cause a pressure drop increase due to a rapid fouling of the filter, energy efficiency
decrease and corrosive symptom increase that can damage the unit.
• The pipes must have the least possible number of bends to minimize load losses and must be adequately supported in order to prevent the connections of the
unait from being excessively stressed.
• Install on-off valves near components that need to be serviced to isolate them when maintenance work needs to be done and to allow them to be replaced without
having to discharge the system.
• Before isolating the pipes and charging the system, carry out preliminary inspections to make sure that there are no leaks.
• Isolate all the chilled water pipes to prevent condensation from forming along the pipes themselves. Make sure that the material used is the steam barrier type,
failing this, cover the insulation with an appropriate protection. Also make sure that the air venting valves can be accessed through the insulation.
• The circuit can be maintained under pressure using an expansion vessel (present in the unit) and a pressure reducer. A system filling device can be used that
automatically, under a pressure value, provides for the loading and maintenance of the desired pressure.
• Check that all plant components are able to withstand the maximum static pressure (depending on the height of the building to be served).
☞
NOTE
• If there is no glycol in the system (antifreeze) or if the unit is not able to remain electrically powered for possible blackouts, in order to avoid possible icing problems,
empty the water during winter.
• The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the water piping.
• Water connections must be made in accordance with the outlook diagram delivered with the unit, with respect to the water intake and water outlet (refer to section
“DIMENSIONAL AND PHYSICAL DATA”).
• If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting the water circuit:
• Use clean pipes only.
• Hold the pipe end downwards when removing burrs
• Cover the pipe end when inserting it through a wall so that no dust and dirt enter.
• Use a good thread sealant for sealing the connections. The sealing must be able to withstand the pressures and temperatures of the system.
• When using non-brass metallic piping,make sure to insulate both materials from each other to prevent galvanic corrosion. Never use Zn-coated parts in the water
circuit. Excessive corrosion of these parts may occur as copper piping is used in the unit’s internal water circuit.
Filling with water
1. Connect the water supply to the relevant connection (see part 9 “fig. 6 - dimensional data and connections” on page 11) and open the valve.
2. Make sure the automatic air purge valve is open (at least 2 turns).
3. Fill with water until the manometer indicates a pressure of approximately 2.0 bar. Remove air in the circuit as much as possible using the air purge valves. Air present
in the water circuit might cause malfunctioning of the backup heater.
☞
NOTE
During filling, it might not be possible to remove all air in the system. Remaining air will be removed through the automatic air purge valves during the first
operating hours of the system. Topping up the water afterwards might be required.
The water pressure indicated on the manometer will vary depending on the water temperature (higher pressure at higher water temperature). However, at
all times water pressure should remain above 0.3 bar to avoid air entering the circuit.
Piping insulation
The complete hydraulic circuit that includes all the pipes must be insulated to avoid heat loss, condensation during operation, reduction of heating or cooling capacity,
as well as to prevent freezing of water pipes during winter.
6.13 Boiler gas connection
Before making the connection, ensure that the unit is arranged for operation with the type of fuel available.
The gas must be connected to the corresponding union (vedi fig. 6) in conformity with current regulations, with a rigid
metal pipe or with a continuous flexible s/steel tube, installing a gas cock between the system and boiler. Make sure
that all the gas connections are tight. Otherwise there may be a risk of fire, explosion or suffocation.
