5. UNIT INSTALLATION
5.1 General notes
5.1.1 Selection of the installation location
The indoor unit of the split system with air to water
heat pump must be installed following these basic
requirements:
• The indoor unit is intended to be installed in an
indoor place and for ambient temperatures ranging
5~30°C. The ambient temperature around the indoor
unit must be >5°C to prevent water from freezing.
• The unit is prepared to be wall mounted (wall bracket
is factory supplied), so make sure that selected wall is
flat and is made of a non-combustible surface, strong
enough for supporting the indoor unit weight.
• Be sure to maintain the recommended servicing
space for future unit servicing and guarantee enough
air circulation around the unit (See
section).
• Take into account that two shut-off valves (factory
supplied) must be installed at the indoor unit inlet/
outlet connections.
• Keep water draining provisions. The safety valve and
the air purge are provided with a drain pipe which are
located at the bottom side of the unit.
• If the event of installing the "Cooling kit" accessory,
the installer is responsible for proper installation and
draining.
• Protect the indoor unit against the entry of small
animals (like rats) which could making contact with
the wires, the drain pipe, electrical parts and may
damage unprotected parts, and at the worst, a fire
will occur.
• Install it in a no-frost environment.
• Do not install the indoor unit in a location with very
high humidity.
• Do not install the indoor unit where electromagnetic
waves are directly radiated to the electrical box.
• Install the unit in a place where in case of water
leakage, any damage to the installation space cannot
be produced.
• Install noise filter when the power supply emits
harmful noises.
• To avoid fire or explosion, do not install the unit in a
flammable environment.
• The air to water heat pump must be installed by a
service technician. The installation must comply with
local and European regulations.
• Try to avoid to put any objects or tools above the
indoor unit.
