Preparing the installation of the outdoor
unit
Choose a sufficient space for carrying the unit to the installation
location in advance.
Do not choose a location where a lot of dust is created such as a
construction work site.
WARNING
• The refrigerant inside the unit is A3- highly flammable (R-290).
• Do not install where there is a risk of combustible gas leakage
or heat sources.
• To handle, purge, and dispose the refrigerant, or break into the
refrigerant circuit, the worker should have a certificate from
an industry-accredited authority in order to be compliant with
regulations.
• Verify that the air to water heat pump is not installed in an
easily accessible area (vandalism/ sabotage/ other harmful
activities).
Choosing the installation location
NOTE
• Read the precautions and requirements in the part "General
safety information".
• The outdoor unit is designed for outdoor installation only, and
for the following ambient temperatures:
– Space heating mode -25~35 °C
– Domestic hot water mode -25~43 °C
–
Space cooling mode 10~46 ℃
Decide the installation location regarding
the following condition and obtain the user’s
approval.
• Choose a location that is dry and sunny, but not exposed to
direct sunlight or strong winds.
• Do not block any passageways or thoroughfares.
• Choose a location where the noise of the air to water heat
pump when running and the discharged air does not disturb
any neighbours.
• Choose a position that enables the pipes and cables to be
easily connected to the other hydraulic system.
• Install the outdoor unit on a flat, stable surface that can
support its weight and does not generate any unnecessary
noise and vibration.
• Position the outdoor unit so that the air flows directly towards
the open area.
• Place the outdoor unit where there are no plants and animals
because they may cause malfunction of outdoor unit.
• Maintain sufficient clearance around the outdoor unit,
especially from a radio, computer, and stereo system.
• The outdoor unit shall be installed in an open space that is
always ventilated.
• Observe the suggested safety zone.
Do not install the air to water Heat Pump in the
following locations:
• A location where there are any potential dangerous substances
like: combustible gas, carbon fiber, mineral oil, arsenic acid,
flammable dust, thinner or gasoline, etc.
• A location where corrosive gas such as sulfurous acid gas
generates from the vent pipe or air outlet. The copper pipe or
connection pipe may corrode and refrigerant may leak.
• A location where the outdoor unit can easily overheat by
solar radiation or if the ambient temperature exceeds 35°C
during cooling mode. A larger installation space is required for
protection against direct solar radiation.
• A location where strong winds may affect the unit. Please also
consider enough clearance to avoid issues with the exhaust air
from the unit if directed at people.
• A location where air is trapped and may short circuit over the
unit. Or where not enough service space is available.
• A too narrow location, as it can lead to problems and potential
damage to the product. Also it can lead to the injuries during
installation or service work.
• A location where not enough ventilation space exists,
especially when installing multiple outdoor units. Obstacles
may disturb the airflow over the unit and can potentially cause
short circuiting between exhaust air and inlet air and may lead
to malfunction.
