2 SAFETY
2.1 APPLIED SYMBOLS
• During normal heat pump system design work or unit
installation, greater attention must be paid in certain
situations requiring particular care in order to avoid damage
to the unit, the installation or the building or property.
Situations that pose a risk to the safety of those in the
•
surrounding area or to the unit itself are clearly indicated in
this manual.
A series of special symbols are used to clearly identify these
•
situations.
• Pay close attention to these symbols and to the messages
following them, as your safety and that of others depends
on it.

• The text following this symbol contains information and instructions
that may be use or that require a more thorough explanation.

Instructions regarding inspections to be made on unit parts or
systems may also be included.
This appliance is filled with R32,
an odourless low burning velocity
refrigerant. If the refrigerant is

leaked, there is a possibility of
ignition if it enters in contact with
an external ignitions source.
!
D A N G E R
This symbol shows that this equipment uses a low burning
velocity refrigerant. If the refrigerant is leaked, there is a
possibility of ignition if it enters in contact with an external
ignition source.
RISK OF EXPLOSION
The compressor must be stopped before removing the refrigerant pipes.
All service valves must be fully closed after pumping down operation.

Before installation, read the installation and
operation manual, and the wiring instruction sheet.
Before performing maintenance and service tasks,
read the service manual.

and Service Handbook.
2.2 ADDITIONAL INFORMATION
!
D A N G E R
• Do not pour water into the unit. These products are equipped
with electrical parts. If the electrical components are in
contact with water, a serious electrical shock will take place.
•
Do not touch or adjust safety devices inside the unit. If these
devices are touched or adjusted, a serious accident can take
place.
• Do not open the service cover or access inside the unit with-
out disconnecting the main power supply.
• In case of fire Turn OFF the main switch, put out the fire at
once and contact your service contractor.
Disconnect the appliance from its power source during
•
service and when replacing parts.
• It must be ensured that the heat pump cannot operate
accidentally without water neither with air inside hydraulic
system.
• Check that the earth wire is securely connected. If the unit
is not properly earthed, it may lead to electric shock. Do
not connect the earth wire to gas piping, water piping,
lighting conductor or earth wire of a telephone.
Fix the cables securely. External forces on the terminals
•
could lead to a fire.
Use an ELB (earth leakage breaker, with an actuation time of
•
0.1s or less). In the event of a fault, there is danger of an
electric shock or a fire if it is not used.
•
Do not charge oxygen, acetylene or other flammable and
poisonous gases into the refrigerant cycle when performing a
leakage test or an air-tightness test. These types of gases are
extremely dangerous and can cause an explosion.
•
Do not install the unit in the following places, otherwise, it
may lead to a fire, deformation, corrosion or failure.
- Places where oil (including machinery oil) splashes.
- Places where flammable gas may generate or flow.
- Places where there is splashing water.
- Places where sulfide gas drifts such as in hot spring.
- Places where strong wind with high salinity blows such as
coast regions, or places with an atmosphere of acidity or
alkalinity.
•
Do not install the unit in the place where silicon gas drifts. If
the silicon gas attaches to the surface of heat exchanger, the
fin surface repels water. As a result, drain water splashes
outside of the drain pan and splashed water runs inside of
electrical box. In the end, water leakage or electrical devices
failure may occur.
