2.2 Personal safety warnings
Always wear appropriate personal protective equipment (gloves, safety goggles, etc.)
when performing installation and/or maintenance on the unit.
Do not touch any switch with wet fingers. Touching a switch with wet
fingers may cause electric shock. Before accessing the electrical
components of the heat pump, disconnect the main power supply
completely.
Disconnect all electricity sources before dismantling the cover panel from
the electric panel or before making any connections or accessing
electrical parts.
To avoid electrocutions, be sure to turn off the power for 1 minute (or more) before
servicing the electrical parts. Even after 1 minute, always measure the voltage at the
terminals of the main circuit capacitors and other electrical parts before touching them
and make sure that the voltage is equal to or less than 50 V dc.
When the cover panels are disassembled, the energized parts can be easily
accessed. Never leave the unit unattended during installation or during maintenance
work when the cover panel is removed.
Do not touch the refrigerant pipes, water piping, or internal parts during and
immediately after operation. Pipes and internal parts may be excessively hot or cold,
depending on the use of the unit.
The hands may be burned by cold or heat in case of improperly touching pipes or
internal parts. To avoid injury, wait until the pipes and internal parts return to their
normal temperature. Alternatively, if access is required, be sure to wear appropriate
safety gloves.

2.3 Transport, storage and handling warnings
The heat pump must be transported, handled and stored vertically. Tipping the
machine may cause the compressor or other components damage.
Do not twist, loosen or pull the external electric cables of the heat pump. Do not insert
any sharp objects through the fan grille or into the fan itself.
Do not wash the interior of the heat pump with water as this may result in electric
shock or fire. For any cleaning and /or maintenance operations, disconnect the main
power supply.
2.4 Freeze protection warnings
The heat pump is a machine that is installed in the exterior of the house, so that it will
be exposed to the extreme climatic conditions of cold in the periods of frost. Due to
this, it is of paramount importance that this type of machine is protected against such
frost. The freezing of the water inside the heat pump causes the heat pump to
breakdown, with the subsequent interruption of its operation and major economic
expenses involving its repair.
It is mandatory to use a safety system in the installation to prevent the freezing of the
water in the machine. We proposes the use of glycol in the water circuit of the heat
pump, or some antifreeze valve system to empty the installation in conditions of low
temperatures. Carefully read the “Freeze Protection” section in this manual for more
detailed information on these systems. We will not cover damages caused by the lack
of any of these antifreeze safety systems.
The electronic controller of the heat pump has a function for protection against the
freezing of the water in its interior in periods of frost. For this function to remain active

- 6-
and on alert, the heat pump must be connected to the mains and have a power
supply, even if it is switched off or not in use.
A water filter should be installed in the installation, in order to avoid obstructions in the
water circuit of the heat pump. It must be installed in the return circuit of the heat
pump and MUST be installed before filling and circulating the water through the
installation. The water filter should be checked and cleaned, if necessary, at least
once a year. IN new installations, however, it is advisable to check it within the first
few months of its commissioning.
3 SYSTEM DESCRIPTION
The unit is a monoblock (single unit) air/water heat pump, specially designed for the
colder climate. There is no need for bore holes and usually the system can be
installed within 1 day.
The unit can both heat hot water effectively at high outdoor temperatures and give a
high output to the heating system at low outdoor temperatures. If the outdoor
temperature drops to a level lower than minus 0°C (factory setting), the auxiliary
heater switches on to ensure the heat pump unit works normally. The unit is also
capable of cooling in the summer. The heat pump controller is an intelligent wired
system.
The unit is rated as 6KW/9KW/12KW/18KW. The Material/components are chosen to
provide a long service life and to fully withstand harsh outdoor conditions.
The unit has two different installation options:
1). Space heating/cooling + DHW (Domestic hot water)
2). Space heating/cooling only or DHW only

4 INSTALLATION
4.1 General points for installation engineer
4.1-1 Preparation before installation
Make sure the site is large enough to hold all the equipment and has enough
operation space.
Measure the hoisting path to ensure that the path to the installation site is
unobstructed and prevent the equipment from reaching the site during
Installation.
Confirm that the power meter capacity and the wire capacity are sufficient and
the phase (three-phase, two-phase) meets the requirements.
Plan the layout of the equipment according to the customer’s site. And strive to
have the shortest and the most straight water pipe and enough space for
operation and maintenance.
For the heat pump with side outlet wind, consider the local wind direction and
choose a reasonable installation direction to avoid the wind direction being opposite.
Current regulations require the heating installation to be inspected before it is commissioned.
The inspection must be carried out by a suitably qualified person and should be documented.
If the heat pump is replaced, the installation must be inspected again. In the event of
installation with unvented (closed) heating systems, make sure the pipeline has an exhaust
valve (an automatic air exhaust valve is included in the heat pump). If necessary, installation
engineer may add additional air exhaust valves to the pipeline.
4.1-2 Sitting the heat pump
The heat pump should be firmly fixed to a base, preferably a concrete base，It
is the most suitable that the right end is 5-10mm higher than the left end. As
shown below:

- 8-
The receiving surface of the device must:
- Allow a solid fixation (Preferably concrete).
- Fully support its weight.
- Have a permeable area below the condensate drainage hole (earth, gravel
bed, sand, etc).
- Do not transmit any vibration to the home, recommending the installation of the
anti-vibration dampers supplied with the heat pump.
In case of installing the device on wall mounts, it will be especially important to isolate the
machine from the transmission of vibrations and noise inside the house, it may be
necessary to install more suitable anti-vibration dampers for the wall mount in addition to
those supplied with the heat pump. Nevertheless, the installation on the ground is the most
advisable.
Straighten the heat pump well to ensure that the condensate water cannot exit through
any paths other than the intended drain hole.
Fasten it firmly using 4 sets of M12 bolts suitable for the base material, with nuts and
washers (available on the market). Make sure that the protruding distance of the bolt does
not exceed 10mm inside the metallic support of the device(leg).
4.1-3 Location requirements between machine and building
The heat pump must be installed exclusively outside the home and, where possible, in a
completely clear area. If a protection is needed around the appliance, it should have wide
openings on the 4 sides and the installation separations indicated in the following figure
must be respected. No obstacle should prevent the circulation of air through the
evaporator and the fan outlet.

- 9-
Consult with the user before choosing the location of the device. It should not be placed
next to sensitive walls, such as on the wall next to a bedroom. Make sure that the location
of the heat pump is not disruptive to neighbors (sound level, air currents generated, low
temperature of the air blown with risk of freezing plants in the path, etc.).
Choose a location that preferably has sunlight and is protected from strong and cold winds.
If the heat pump is exposed to gusts of wind that make it possible to overturn it, it should
be supported by suitable guys, as indicated in the figure.

- 10-
The device must be sufficiently accessible for subsequent installation and maintenance
work. Make sure that the passage of the hydraulic and electrical connections to the interior
of the house is possible and comfortable. The spacing measures indicated in the figure
above are those strictly necessary to ensure correct operation of the device; however,
sometimes, it will be essential to provide more space for maintenance work.
The heat pump is a device specially designed for outdoor installation. Nevertheless, avoid
installing it in a place where it may be exposed to significant water stains or spills (e.g.
under a faulty gutter, near gas outlets,etc.) . Move the appliance away from heat sources
and flammable products.
In areas where abundant and copious snowfalls occur, special care must be taken to
protect the heat pump from possible obstructions due to accumulation of snow around it.
The obstruction of the air inlet and/or outlet of the machine due to the accumulation of
snow may cause malfunction of the unit and possible breakdowns. The heat pump must
be raised at least 100 millimeters above the maximum expected snow level. In turn, the
roof should be protected from accumulation of snow, by means of a roof projecting from
the building or a similar structure.
4.1-4 Condensate drainage
In normal operation, the heat pump can evacuate large amounts of water, for which the
heat pump provides a hole in the bottom of the appliance. Be sure not to obstruct this hole
during the installation process of the appliance.

- 11-
Preferably install the device in a well-drained place. To do this, it is advisable to provide a
bed of gravel, sand or similar materials below said hole. If the drain hole of the heat pump
is covered by a mounting base or by the floor, lift the unit to leave a free space of at least
100mm below it.
If it is installed on a terrace or facade, the condensate outlet must be led to a drain to avoid
inconvenience and/or damage caused by the dripping of condensate water. If the
installation is carried out in a region where the temperature can be below 0°C for a long
period of time,
4.1-5 Accessories supplied
The following accessories are supplied in the interior of the heat pump. Before proceeding
with the installation of the machine, make sure that you receive them and that they are in
good condition.
Documentation: Inside the machine, open the front door to find the
documentation bag, where all the manuals and documents
necessary for the use and installation of the heat pump are
included.
Controller: It is supplied inside the machine and can be found by removing
the cover of the electronic boards. Before connecting the
power supply to the machine, the controller should be installed
inside the house.

- 12-
Drain valve: It is supplied inside the machine, tied with a flange to one leg of
the compressor. This key must be installed in the drain socket
on the back of the heat pump before filling the water in the
heating/cooling circuit.
4.1-6 Controller
The unit is equipped with an external electronic controller that handles all functions
necessary for heat pump operations. Defrosting, stop at max/min temperature,
connection of the compressor heater as well as enabling the aux electrical heater,
monitoring of motor protection and pressure sensors are all controlled.
The number of starts and the operating time after this power-on can also be read.
The controller is set during installation and can be used during a service.
Under normal operating conditions the home owner does not need to have access to
the controller. The unit has an integrated electronic outlet water temperature sensor
that limits the outlet temperature up to 60°C.
4.2 Installation design
The unit can be installed in several different ways.
The safety equipment must be installed in accordance with current regulations for all
installation options.
When connecting with the unit, the total water volume in the heat pump pipe system
and buffer tank must be at least 10 liters per KW of output.

4.3 Pipe Connection
Schematic diagram of water pipe connection between heat pump
and buffer tank.
For the pipe size is: diameter 28mm, 1 inch, and pipe joint specification. is DN25,
material can be copper or stainless steel.
The pipe must be flushed before the heat pump is connected, so that any
contaminants do not damage the components parts.
The heating/cooling water inlet and outlet direction must be connected according to
the marked areas on the heat pump.
A water filter must be installed in the water circuit of the heat pump, in order to avoid
obstructions or narrowing caused by dirt in the installation. The filter MUST be installed
before filling the installation with water and in the return branch of the machine, to avoid the
entry of dirty water into the heat exchanger (condenser). The type of filter installed must be
adapted to the particular characteristics of each installation (type and material of the water
pipes, type of
water used, water volume of the installation, etc.). The water filter should be checked and
cleaned, if necessary, at least once a year. In new installation, however, it is advisable to
check it within the first few months of its commissioning.
A flexible damping pipe must be installed between the heat pump and the buffer tank to
balance the height difference between the machine and the pipe and reduce the
transmission of vibration.
We recommend inserting cut-off valves between the installation piping and the heat pump
to simplify maintenance tasks.
Leave a free space around the heat pump for carrying out any maintenance and repair
operations.

- 17-
Air vent valves and suitable devices should be fitted for the correct removal of air from the
circuit during the filling stage.
All water circuit piping MUST be insulated to prevent condensation during
operation in cooling mode and reduction of the cooling and heating capacity, as well as to
prevent freezing of outside pipes during winter. The minimum insulation thickness of the
pipes should be 19mm(0.039W/mK), preferably comprising a closed cell insulation or a
vapour barrier. In outdoor areas exposed to the sun, the insulation must be protected from
the effects of degradation.
The water circulation pump must at all times be operational (even if unit is not
running) to prevent any possible damage due to freezing. Even when in standby
mode, the circulation pump is controlled directly from the unit, which takes the
outdoor temperature and temperature in pipe into consideration to decide whether to
circulate water within the system.
Important: Even though the unit has anti-freeze protection, if the circulation pump
fails or there is a problem with the power supply, there is still a risk of damage due to
freezing. During the installation Anti-freeze (Ethylene Glycol) is strongly
recommended. If the air temp is ever lower than 0°C, it must use enough glycol.
4.4 Electrical Connection
The electrical installation of the heat pump and its electrical accessories should be carried
out by qualified personnel, subject to the current installation regulations on the matter. The
electrical installation must be connected so that the heat pump can be fully isolated and
disconnected for the safe execution of any maintenance operations.
Th machine has 2 holes with cable grommets in its back side to introduce all connection
cables inside the machine. The cables exposed to the weather conditions of the exterior
should be protected by means of protective raceways or pipes. Alternatively, they should be
of a suitable category for use outdoors (H07RN-F type or higher). It is also advisable to
keep the high -voltage cables (general supply, diverted valves, electrical heaters, circulation
pumps, etc.) at a minimum distance of 25 mm low-voltage cables (controller board cable,
temperature sensors, room sensor, etc.) and drive them through independent pipes.
IMPOTTANT: Before carrying out any work on the electrical installation
of the heat pump, always ensure it is disconnected from
the mains.
