IMPORTANT!
Please Read Before Starting
This Air-to-Water must be installed by the sales dealer or
installer.
This information is provided for use only by authorized
persons.
Be sure to read the installation instructions relevant to
the VRF system connected to this Air-to-Water and all
appliances connected to the VRF system.
For safe installation and trouble-free operation, you must:
Carefully read this instruction booklet before beginning.
Follow each installation or repair step exactly as shown.
This Air-to-Water shall be installed in accordance with
National Wiring Regulations.
For water circuit installation work, follow to relevant
European and national regulations (including EN61770)
and local plumbing and building regulation.
The unit is only for use in a closed water system.
Utilization in an open water circuit may lead to excessive
corrosion of water piping and risk of incubating bacteria
colonies, particularly Legionella, in water.
Pay close attention to all warning and caution notices
given in this manual.
WARNING
This symbol refers to a hazard or unsafe
practice which can result in severe
personal injury or death.
CAUTION
This symbol refers to a hazard or unsafe
practice which can result in personal injury
or product or property damage.
If Necessary, Get Help
These instructions are all you need for most installation
sites and maintenance conditions. If you require help for a
special problem, contact our sales/service outlet or your
certified dealer for additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
WARNING
Do not modify the wiring of indoor/outdoor
unit for installation of other components
(i.e. heater, etc). Overloaded wiring or wire
connection points may cause electrical
shock or fire.
CAUTION
Do not apply excessive force to water
pipes that may damage the pipes. If water
leakage occurs, it will cause flooding and
damage to other properties.
Carry out drainage piping as mentioned in installation
instructions. If drainage is not perfect, water may enter the
room and damage the furniture.
SPECIAL PRECAUTIONS
WARNING
WARNING When Wiring
Risk of Electric Shock
WARNING
ELECTRICAL SHOCK CAN
CAUSE SEVERE PERSONAL
INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD
ATTEMPT TO WIRE THIS
SYSTEM.
•Do not supply power to the unit until
all wiring and tubing are completed or
reconnected and checked.
•Highly dangerous electrical voltages are
used in this system.
Carefully refer to the wiring diagram and
these instructions when wiring. Improper
connections and inadequate grounding
can cause accidental injury or death.
•Connect all wiring tightly. Loose wiring
may cause overheating at connection
points and a possible fire hazard.
•Provide a power outlet to be used
exclusively for each unit.
•Provide a power outlet exclusively for
each unit, and full disconnection means
having a contact separation in all poles
must be incorporated in the fixed wiring
in accordance with the wiring rules.
•To prevent possible hazards from
insulation failure, the unit must be
grounded.
•This equipment is strongly recommended
to be installed with Earth Leakage
Circuit Breaker (ELCB) or Residual
Current Device (RCD). Otherwise, it may
cause electrical shock and fire in case
of equipment breakdown or insulation
breakdown.
When Transporting
Be careful when picking up and moving
the indoor and outdoor units. Get a partner
to help, and bend your knees when lifting
to reduce strain on your back. Sharp
edges or thin aluminum fins on the air
conditioner or Air-to-Water can cut your
fingers.

When Installing…
Select an installation location which is
rigid and strong enough to support or
hold the unit, and select a location for
easy maintenance.
…In a Room
Properly insulate any tubing run inside a
room to prevent “sweating” that can cause
dripping and water damage to walls and
floors.
WARNING
CAUTION
Keep the fire alarm and
the air outlet at least
1.5 m away from the unit.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete
blocks to provide a solid, level foundation
for the outdoor unit. This prevents water
damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down
with bolts and a metal frame. Provide a
suitable air baffle.
…In a Snowy Area (for Heat Pump-
type Systems)
Install the outdoor unit on a raised
platform that is higher than drifting snow.
Provide snow vents.
…In laundry rooms
Do not install in laundry rooms. Indoor
unit is not drip proof.
When Connecting Refrigerant Tubing
Pay particular attention to refrigerant
leakages.
WARNING
WARNING
• When performing piping work, do not
mix air except for specified refrigerant
(R410A) in refrigeration cycle. It
causes capacity down, and risk of
explosion and injury due to high
tension inside the refrigerant cycle.
•If the refrigerant comes in contact
with a flame, it produces a toxic gas.
•Do not add or replace refrigerant
other than specified type. It may
cause product damage, burst and
injury, etc.
•Ventilate the room immediately, in the
event that is refrigerant gas leaks during
the installation. Be careful not to allow
contact of the refrigerant gas with a
flame as this will cause the generation
of toxic gas.
•Keep all tubing runs as short as
possible.
•Apply refrigerant lubricant to the
matching surfaces of the flare and union
tubes before connecting them, then
tighten the nut with a torque wrench for
a leak-free connection.
•Check carefully for leaks before starting
the test run.
•Do not leak refrigerant while piping work
for an installation or re-installation, and
while repairing refrigeration parts.
Handle liquid refrigerant carefully as it
may cause frostbite.
When Servicing
•Turn the power OFF at the main
power box (mains) before opening
the unit to check or repair electrical
parts and wiring.
•Keep your fingers and clothing away
from any moving parts.
•Clean up the site after you finish,
remembering to check that no metal
chips or bits of wiring have been left
inside the unit.
WARNING
WARNING
•This product must not be
modified or disassembled under
any circumstances. Modified or
disassembled unit may cause fire,
electric shock or injury.
•Do not clean inside the indoor and
outdoor units by users. Engage
authorized dealer or specialist for
cleaning.
•In case of malfunction of this
appliance, do not repair by yourself.
Contact the sales dealer or service
dealer for repair.

WARNING
CAUTION
• Do not touch the air inlet or the
sharp aluminum fins of the
outdoor unit. You may get injured.
• Ventilate any enclosed areas when
installing or testing the refrigeration
system. Leaked refrigerant gas, on
contact with fire or heat, can produce
dangerous toxic gas.
• Confirm after installation that no
refrigerant gas is leaking. If the gas
comes in contact with a burning
stove, gas water heater, electric room
heater or other heat source, it can
cause the generation of toxic gas.
Others
WARNING
CAUTION
• Do not sit or step on the unit, you
may fall down accidentally.
• Do not touch the air inlet or the
sharp aluminum fins of the
outdoor unit. You may get injured.
• Do not stick any object into the
FAN CASE.
You may be injured and the unit
may be damaged.
