N O T E
Please refer to the Installation and Operation Manual of the outdoor unit for
information on the installation of the outdoor unit.
5.1.2 Selection of the installation location
The YUTAMPO tank of the split system with sanitary hot water
heat pump must be installed satisfying these basic requirements:
• The YUTAMPO tank is intended to be installed in an indoor
environment with an ambient temperature range of 5~30 °C.
The ambient temperature around the indoor unit must be
>5°C to prevent water from freezing.
• The indoor unit is designed to be floor mounted. The floor of
the place chosen for installation must be flat, with the surface
made of a non-burnable material, and must be strong enough
to withstand the weight of the indoor unit as well as the weight
of the DHW tank when it is completely full of water.
• The floor at the place of installation must be waterproof and
have a proper drainage, in order to limit the extent of damage
in case of water leakage.
• The recommended servicing space must be kept to allow
servicing as well as a sufficient circulation of air around the
unit.
• Enough space must be reserved for the installation of a
required pressure and temperature relief valve at the DHW
inlet connection of the tank (as close as possible to the tank).
A shut-down valve (field supplied) must be also installed at
the DHW outlet connection.
• It is the responsibility of the installer to ensure that installation
and draining works are compliant with regulations.
• The indoor unit must be protected against the intrusion of
small animals (like rodents) which could damage the wiring,
drain pipes or electrical parts, causing a fire in the worst case.
• The installation environment shall be free of frost and
excessive humidity.
• The unit shall not be installed in locations where it is exposed
to oil, smoke, dust or particles, such as kitchens or factories.
• The unit shall not be installed in locations where it is exposed
to large voltage fluctuations or electromagnetic interference,
such as hospitals or workshops.

• If the unit is to be installed in a coastal area where it is
exposed to salty air, in a hot spring area or other areas where
special environmental conditions prevail, consult your dealer
before installing the unit.
• Do not install the indoor unit where electromagnetic waves
are directly radiated to the electrical box.
• Install the YUTAMPO system at a distance of 1 m or more
from TV sets, radios, radio antennas or similar devices. In
areas with poor reception, increase the distance so that units
do not interfere with reception.
• The unit must be installed in a place where no damage can
be produced as a result of water leakage.
• A noise filter must be installed when the power supply emits
harmful noise.
• To avoid fire or explosion, do not install the unit in a
flammable environment.
• The sanitary hot water heat pump must be installed by a
service technician. The installation must comply with local
and European regulations.
• Do not put any objects or tools on top of the indoor unit.
5.1.3 Unpacking
All units are supplied with a wooden base, packed inside a
cardboard box and covered with a plastic bag.
For unpacking, first place the unit on the assembly area, as close
as possible to its final installation location, to avoid damages
during transport. Two persons are required.
1 Cut the strapping bands and remove the adhesive tapes.
2 Remove the cardboard cap and then the plastic bag around
the unit. Afterwards, remove the rest of cardboard parts.
3 Lift the YUTAMPO unit from the wooden base and place it
carefully on the floor, as near as possible to its final location.

C A U T I O N
• Two or more persons are required when lifting because of the heavy
weight of the unit (50 or 56 kg, depending of the model)
• Be specially careful with the mounting foot once the unit is on the floor.
Avoid harsh handling of the unit, as it could cause damage to the foot.
