• Instructions regarding inspections to be made on unit parts or systems
may also be included.
2.2 ADDITIONAL INFORMATION ABOUT SAFETY
!DANGER
• DO NOT CONNECT THE POWER SUPPLY TO THE INDOOR UNIT
PRIOR TO FILLING DHW CIRCUITS WITH WATER AND CHECKING
WATER PRESSURE AND THE TOTAL ABSENCE OF ANY WATER
LEAKAGE.
• Do not pour water over the indoor unit electrical parts. A serious
electrical shock may occur if the electrical components enter in
contact with water.
• Do not touch or adjust the safety devices inside the sanitary hot
water heat pump. Touching or adjusting these devices may cause
a serious accident.
• Do not open the service cover or access the sanitary hot water
heat pump without disconnecting the main power supply.
• In case of re, turn the main switch off immediately, put out the
re at once and contact your service contractor.
• It must be made sure that the sanitary hot water heat pump
cannot operate accidentally either without water in the hydraulic
system or with air inside it.
!CAUTION
• Do not use any sprays such as insecticide, lacquer, hair spray or other
ammable gases within approximately one meter from the system.
• If the circuit breaker in the installation or the fuse in the unit are
triggered often, stop the system and contact your service contractor.
• Do not make service or inspections tasks by yourself. This work must
be performed by a qualied service person.
• This appliance must be used only by adult and capable people,
having received the technical information or instructions to handle the
appliance properly and safely.
• Children should be supervised to ensure that they do not play with the

• Do not let any foreign body into the water inlet and outlet piping of the
sanitary hot water heat pump.
GENERAL INFORMATION
PMML0451 rev.2 - 03/2018

2.3 IMPORTANT NOTICE
• PLEASE READ THE MANUAL CAREFULLY BEFORE
STARTING TO WORK ON THE INSTALLATION OF THE
SANITARY HOT WATER HEAT PUMP SYSTEM. Failure to
observe the instructions for installation, use and operation
described in this documentation may result in operating
failure including potentially serious faults, or even the
destruction of the sanitary hot water heat pump system.
• This sanitary hot water heat pump has been designed for
the production of sanitary hot water for human consumption.
Do not use it for other purposes such as for drying clothes,
heating foods or for any other heating process.
• Refer to the codication of models to conrm the main
characteristics of your system.
• Check and make sure that the explanations of each part of
this manual apply to your specic model of sanitary hot water
heat pump.
• Verify that all the information required for the correct
installation of the system is correct according to the manuals
bundled with outdoor and indoor units. Contact your
distributor if it is not the case.
• Signal words (NOTE, DANGER and CAUTION) are used
to identify levels of hazard seriousness. Denitions for
identifying hazard levels are provided in the rst pages of this
document.
• This manual should be considered as an integral part of the
sanitary hot water heat pump, and must be kept for future
reference.
• Both the indoor and outdoor unit must be installed at a
location, structure or support prepared to withstand a heavy
weight. Otherwise, noise and vibration may increase, and the
units may collapse and cause damage to property or physical
injuries, particularly in case of an earthquake or a similar
phenomenon.
• Keep the water temperature of the system above the freezing
temperature (above 5 ºC).
• Please install a thermostat-type mixer tap in each hot water
supply spot to prevent scald accidents, and a drain trap in the
drainage piping.
• Please use dielectric joints to prevent the electrolysis
phenomenon.
• Piping parts around the tank such as the pressure-relief valve
and the drain valve must be easily accessed for maintenance
and inspection.
• Be sure to use the specied piping set for R410A. Otherwise,
this may result in damage to copper pipes and operational
failure.
• Make sure that nothing but the specied refrigerant (R410A)
is inside the refrigerant cycle when installing or removing the
sanitary hot water heat pump. If air or moisture remain in the
refrigeration cycle, pressure may become abnormally high
and cause rupture.
• Ventilate the room if any refrigerant has leaked out during the
installation work. The refrigerant produces a poisonous gas if
exposed to re.
• The drainage gas ows backward if there is no drain trap,
which may increase the corrosion of the hot water pump
considerably, leading to breakdown.
• Be sure to use a dedicated power circuit. Never use a power
circuit shared with another appliance.
• For wiring, use a cable long enough to cover the entire
distance with no intermediate connections. The power circuit
must be a dedicated one, without additional loads on the
power supply. Failure to do so may result in abnormal heat,
electrical shock, or re.
• Be sure to connect both outdoor and indoor units to ground.
An improperly made or incomplete ground connection may
cause damage or short-circuits that could result in electrical
shock and re. A high surge current from lightning or other
sources may cause damage to the outdoor unit. Ground
connections must not be made to utility pipes, gas pipes,
water pipes, surge absorb, lightning rods or telephone ground
connections.
• Be sure to install an earth leakage and a circuit breaker
according to local regulations. Failure to do so may result in
electrical shock.
• The operation modes of these units are controlled by the unit
controller.
• HITACHI pursues a policy of continuous improvement in

6 Test and check
5.3.1 General notes before performing piping
work
• Arrange locally-supplied copper pipes.
• Select pipes of the appropriate material, with sufcient
thickness to withstand pressure.
• Select clean copper pipes. Make sure that there is no dust
or moisture inside the pipes. Blow the inside of the pipes
with oxygen-free nitrogen to remove any dust and foreign
materials before connecting them.
?NOTE
A refrigerant system with no moisture or oil contamination will yield
maximum performance and life cycle, whereas a poorly prepared system
will not. Take particular care to ensure that all copper piping is clean and
dry internally.
• Cap the end of the pipe when it is to be inserted through a
wall hole.
• Do not put pipes on the ground directly without a cap or vinyl
tape at the end of the pipe.
• If piping installation is not completed until the following day or
over a longer period of time, braze off the ends of the piping
and charge with oxygen-free nitrogen through a Schrader
valve type access tting to prevent moisture and particle
contamination.
• It is advisable to insulate the water pipes, joints and
connections in order to avoid heat loss and dew condensation
on the surface of the pipes or accidental injuries due to
excessive heat on piping surfaces.
UNIT INSTALLATION
PMML0451 rev.2 - 03/2018

• Do not use insulation material that contains NH3, as it can
damage copper pipe material and become a source of future
leakage.
• It is recommended to use exible joints for the inlet and outlet
of water piping, in order to avoid the transmission of vibration.
• The refrigerant and water circuits must be installed and
inspected by a licensed technician and must comply with all
the relevant European and national regulations.
• It is recommended to perform a thorough water pipe
inspection after completion of piping work to make sure that
there is no water leakage in the space heating circuit.
5.3.2 DHW pipe connection
The connection between the DHW installation and the DHW tank
must be done taking the following considerations into account:
1 A pressure and temperature relief valve must be installed at
the DHW inlet connection (as close as possible to the tank) to
provide the following functions:
• Pressure protection
• No-return function
• Shut-down valve
• Filling
• Draining
If not, a specic device for each function should be installed.
2 A shut-down valve (eld supplied) must also be installed in
the DHW system.
!DANGER
Do not connect the power supply to the indoor unit prior to lling the
DHW circuit with water and checking water pressure and the total
absence of any water leakage.

?NOTE
The discharge pipe should always be open to the atmosphere, free of frost
and obstruction, and in continuous descending slope in order to let water
out in case that a leakage occurs.
5.3.3 Requirements and recommendations for
the hydraulic circuit
• When the unit is stopped during shutdown periods and the
ambient temperature is very low, the water inside the pipes
may freeze, thus damaging the pipes. In these cases, the
installer shall ensure that the water temperature inside the
pipes does not fall below the freezing point.
• Fresh water must circulate inside the water circuit of the
DHW tank at least once every day during the rst days
after the installation has been performed. Additionally, it is
advised to ush the system with fresh water when there is no
consumption of DHW during long periods of time.
• A pressure with a nominal value of 7 bar must be tted in
case that the pressure of domestic cold water inlet is higher
than the design pressure of the equipment (6 bar).
• The installation must satisfy the requirements of applicable
legislation in terms of piping connection and materials,
hygienic measures and testing, as well as the possible
requirements for the use of some specic components such
as thermostatic mixing valves, differential pressure overow
valves, etc.
5.3.4 Filling the DWH tank with water
Follow the steps below when starting up the unit for the rst time
or when it has not been used for an extended period of time
1 Open the outlet water taps of the DHW, to expel all the air
from inside the tank.
2 Turn on all the connected mixer taps (hot water side).
3 Open the inlet valve of the DHW tank in order to ll the tank.
If there is a shut-down valve installed in the DHW tank outlet,
open it to allow circulation through the DHW installation.
4 When water begins to ow from the outlet water taps of the
DHW installation, close all these taps.
5 Turn off all the connected mixer taps.
6 Inspection
-1 After lling the tank, check all pipe, heater and anode
joints and the tank for leakage.
-2 Check operation of the pressure relief valve.
-3 After heating water for the rst time, check water
leakage from the pipe, heater and anode joints and the
tank once more.
!CAUTION
• Check carefully for leaks in the water circuit, connections and circuit
elements.
• Check that the water pressure in the circuit is lower than 7 bars.
• Fill the circuit with tap water. Water that conforms to the drinking
water regulation in each country must be used. Do not use water from
sources not subject to sanitary control like wells, rivers or lakes, since
it may have a high content of impurities, salinity, lime, etc.
• Please install the a water softening device when the hardness of water
is high. (Maximum hardness French degree 25 °F or equivalent rules)

?NOTE
Do not perform connection work with only one wrench. Always use two
wrenches (keeping one of them xed, while using the other to tighten the
connection). Refrigerant leakage may occur if the screwing procedure is
performed with only one wrench.
4 After having performed the connection of refrigerant piping,
seal the open space between the knock-out hole and
refrigerant pipes with insulation material.
5 Follow the instruction “3) Remove air from the Pipe and gas
leakage inspection” as indicated in the installation manual of
the outdoor units.
!CAUTION
• Check for refrigerant leakage in detail. If a large refrigerant leakage
occurred, it would cause difculty with breathing. Also, harmful gases
would be generated if there was a re in the room.
• If the are nut is tightened too hard, it may crack over time and cause
refrigerant leakage.
Maximum permitted concentration of HFCs
The R410A refrigerant (charged in the outdoor unit) is a non-
ammable, non-toxic gas. However, if leakage occurs and the
room becomes lled with gas, it may cause suffocation. The
maximum permissible concentration of HFC gas according to
EN378-1 is 0.44 kg/m3, and the volume of the installation room
must be greater than 3.2 m3in order to avoid suffocation in case
of leakage.
The formula used for the calculation of the maximum refrigerant
concentration allowed in case of refrigerant leakage is the
following:
R
— = C
V
R: Total quantity of refrigerant charged (kg)
V: Volume of the room (m³)
C: Refrigerant concentration
If the volume of the room does not meet this minimum value,
some effective measures must be carried out after installation to
prevent suffocation in case of leakage.
