■ Operation range
(*) The unit can not operate in cold weather conditions below -15℃. If
it is necessary to operate, an external auxiliary heat source must
be added as a backup heater. the backup heater also serves as a
backup in case of malfunctioning of the unit and for freeze
ptrotection of the outside water piping during winter time.
These models have an antifreeze function that allows the use of
heat pumps to keep the water system free from freezing under all
conditions. If there is an accident or intentional power outage, it is
recommended to use ethylene glycol.

This installation & ow
ner's man
ual does not include the selection
procedure and water system design procedure. Only some
precautions and tips and tricks about the design of the water circuit
are given in a separate chapter of this manual. Once the selection is
done and the water system is designed, this manual describes the
procedures for handing, installing and connecting the unit, This
manual has been prepared to ensure adequate maintenance of the
unit, and it will provide help if problems occur.
This unit is designed to cool/heat water and must be
used in applications compatible with its performance
characteristics, i.e. residential or commercial applications
combined with a fan coil unit, low temperature radiators
and underfloor heating. It should never be used for
underfloor cooling, as doing so may damage the plate
heat exchanger.

3. SAFETY CONSIDERATIONS
The precautions listed here are divided into the following types.
They are quite important, so be sure to follow them carefully.
Meanings of DANGER, WARNING, CAUTION and NOTE symbols.
DANGER
Indicates an imminently hazardous situation which if not
avoided, will result in death or serious injury.
WARNING
Indicates a potentially hazardous situation which if not
avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It is also
used to alert against unsafe practices.
NOTE
Indicates situations that could only result in accidental
equipment or property damage.
■ Before touching electric terminal parts, turn off power switch.
■ When service panels are removed, live parts can be easily
touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
■ Do not touch water pipes during and immediately after operation
as the pipes may be hot and could burn your hand. To avoid injury,
give the piping time to return to normal temperature or be sure to
wear protective gloves.
■ Do not touch any switch with wet fingers. Touching a switch with
wet fingers can cause electrical shock.
■ Before touching electrical parts, turn off all applicable power to
the unit.
DANGER
WARNING
■ Tear apart and throw away plastic packaging bags so that children
will not play with them.
Children playing with plastic bags face danger of death by
suffocation.
■ Safely dispose of packing materials such as nails and other metal
or wood parts that could cause injuries.
■ Ask your dealer or qualified personnel to perform installation work
in accordance with this manual. Do not install the unit yourself.
Improper installation could result in water leakage, electric shocks
or fire
■ Be sure to use only specified accessories and parts for installation
work.
Failure to use specified parts may result in water leakage, electric
shocks, fire, or the unit falling from its mount.
■ Install the unit on a foundation that can withstand its weight.
■ Insufficient physical strength may cause the equipment to fall and
possible injury
■ Perform specified installation work with full consideration of strong
wind, hurricanes, or earthquakes.
Improper installation work may result in accidents due to equipment
falling.
■ Make certain that all electrical work is carried out by qualified
ersonnel according to the local laws and regulations and this
manual using a separate circuit.
Insufficient capacity of the power supply circuit or improper electrical
construction may lead to electric shocks or fire.
■ Be sure to install a ground fault circuit interrupter according to local
laws and regulations.
Failure to install a ground fault circuit interrupter may cause electric
shocks and fire.
■ Make sure all wiring is secure. Use the specified wires and ensure
that terminal connections or wires are protected from water and
other adverse external forces.
