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 relating directly to your safety.
●
Not taking these instructions into account could lead to
serious, very serious or even fatal injuries to you and
others.
●
The text following this symbol contains information and
instructions relating directly to your safety.
●
Not taking these instructions into account could lead to minor
injuries to you and others.
●
Not taking these instructions into account could lead to unit
damage.
●
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.
Caution, risk of fire!
This appliance is lled 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.
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.
Symbol Explanation
Before installation, read the installation and
operation manual, and the wiring instruction sheet.
Before performing maintenance and service tasks,
read the service manual.
For more information, see the Technical,
Installation and Service Handbook.
2.2 ADDITIONAL INFORMATION
●
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 re Turn OFF the main switch, put out the re 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 re.
●
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 re if it is not used.
●
Do not charge oxygen, acetylene or other ammable
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 re, deformation, corrosion or failure.
- Places where oil (including machinery oil) splashes.
- Places where ammable gas may generate or ow.
- Places where there is splashing water.
- Places where sulde 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 n 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.
