10 START-UP AND CONFIGURATION

The unit should be configured by the installer to
match the installation environment (outdoor climate,
installed options, etc.) and user expertise.
CAUTION
It is important that
chapter is read sequentially by the installer and
that the system is configured as applicable.
10.1 Initial start-up at low outdoor
ambient temperature
During initial start-up and when water temperature is
low, it is important that the water is heated gradually.
Fail to do so may result in concrete floors cracking due to
rapid temperature change. Please contact the responsible
cast concrete building contractor for further details.
To do so, the preheating function for floor can be used.
(Please refer to "SPECIAL FUNCTION" in "FOR
SERVICEMAN")

10.2 Pre-operation checks

Checks before initial start-up.
DANGER
Switch off the power supply before making any
connections.
After the installation of the unit, check the following
before switching on the circuit breaker:
Field wiring：Make sure
between the local supply panel and unit and valves
(when applicable), unit and room thermostat (when
applicable), unit and domestic hot water tank, and
unit and backup heater kit have been connected
according to the instructions described in the
chapter 9.6 "Field wiring", according to the wiring
diagrams and to local laws and regulations.
Fuses, circuit breakers, or protection devices Check
that the fuses or the locally installed protection
devices are of the size and type specified in 15
"TECHNICAL SPECIFICATIONS". Make sure that no
fuses or protection devices have been bypassed.
Backup heater circuit breaker：Do not forget to
turn on the backup heater circuit breaker in the
switchbox (it depends on the backup heater type).
Refer to the wiring diagram.
Booster heater circuit breaker：Do not forget to
turn on the booster heater circuit breaker (applies
only to units with optional domestic hot water tank
installed).
Ground wiring: Make sure that the ground wires have
been connected properly and that the ground
terminals are tightened.
Internal wiring: Visually check the switch box for
loose connections or damaged electrical
components.
Mounting：Check that the unit is properly mounted,
to avoid abnormal noises and vibrations when
starting up the unit.
Damaged equipment: Check the inside of the
unit for damaged components or squeezed pipes.
Refrigerant leak：Check the inside of the unit for
refrigerant leakage. If there is a refrigerant leak, call
your local dealer.
Power supply voltage：Check the power supply
voltage on the local supply panel. The voltage must
correspond to the voltage on the identification label
of the unit.
Air purge valve: Make sure the air purge valve is
open (at least 2 turns).
Shut-off valves: Make sure that the shut-off valves
are fully open.

10.3 Failure diagnosis at first installation
If nothing is displayed on the user interface, it is
necessary to check
abnormalities before diagnosing possible error codes.
-Disconnection or wiring error (between power supply
and unit and between unit and user interface).
-The fuse on the PCB may be broken.
If the user interface shows "E8" or "E0" as an error
code, there is a possibility that there is air in the
system, or the water level in the system is less than
the required minimum.
If the error code E2 is displayed on the user interface,
check the wiring between the user interface and unit.
More error code and failure causes can be found in
14.3 "Error codes".
10.4 Installation Manual

10.4.1 Safety precaution

Read the safety precautions carefully before installing
the unit.
Stated below are important safety issues that must
be obeyed.
Conform there is no abnormal phenomena during test
operation after complete, then hand the manual to
the user.
Meaning of marks:
Means improper handling may lead to personal
death or severe injury.
Means improper handling may lead to personal
injury or property loss.
Please entrust the distributor or professionals to
install the unit.
Installation by other persons may lead to
imperfect installation, electric shock or fire.
Strictly follow this manual.
Improper installation may lead to electric shock or
fire.
Reinstallation must be performed by professionals.
improper installation may lead to electric shock or
fire.
Do not disassemble your air conditioner at will.
A random disassembly may cause abnormal
operation or heating, which may result in fire.
The wired controller should be installed indoors and
not be exposed to sunlight directly.
Do not install the unit in a place vulnerable to leakage
of flammable gases.
Once flammable gases are leaked and left around the
wired controller, fire may occure.
The wiring should adapt to the wired controller
current.
Otherwise, electric leakage or heating may occur
and result in fire.
The specified cables shall be applied in the wiring.
No external force may be applied to the terminal.
Otherwise, wire cut and heating may occur and result
in fire.
