OPERATION AND PERFORMANCE
The cooling and heating operation in a VRF system
In extremely strong winds, please prevent the air from flowing
backwards into the outdoor unit.
● Each indoor unit can be controlled alone. The indoor units in the
same system cannot run cooling and heating at the same time.
Choose an appropriate place where the noise and hot or cold
wind blown out of the outdoor unit will not cause
inconvenience to your neighbors or affect the growth of an
animal or plant.
● Explanation of priority mode operation
Priority mode can only be set on the master unit. When an indoor
unit is in mode conflict with the outdoor units the unit displays the
mode conflict error.
Do not place appliances that have naked flames under or
near the unit, as heat from the appliance can damage the
unit.
1.
Auto priority mode (default): In auto priority mode, the
outdoor unit will operate in heating priority mode or cooling
priority mode according to the outdoor ambient temperature.
Do not allow children to play near this unit, as doing so risks
injury.
2.
Heating priority mode:
a)
During cooling operation: If an indoor unit requests
heating, the outdoor units stop and then restart in
heating mode after 7 minutes. Indoor units requesting
heating then start in heating mode and indoor units
requesting cooling display the mode conflict error.
b)
During heating operat ion: If an indoor unit requests
cooling, the outdoor units ignore the request and
continue to run in heating mode. The indoor unit
requesting cooling displays the mode conflict error. If all
the indoor units requesting heating are later turned off
and one or more indoor units are still requesting cooling,
the outdoor units restart in cooling mode after 7 minutes
and any indoor units requesting cooling then start in
cooling mode.
This unit should not be operated by children or by adults that
are not capable of operating the unit safely.
When disposing of this unit, ensure that all applicable
legislation regarding the disposal of refrigerant, oil and other
materials is adhered to.
Leave the power on for a minimum of 12 hours prior to
running the system to ensure that the crankcase heaters
have heated the compressor oil sufficiently.

TROUBLES AND CAUSES
CAUTION
The following operation is performed in order to prevent the
heating capacity from dropping or cold air from blowing
This unit should only be serviced and maintained by a
professional air conditioning service engineer. Incorrect
servicing or maintenance can cause electric shock, fire or
leakage of water. If the unit displays protection or error code,
contact your dealer for servicing and maintenance.
● Defrost operation
a) When the system is running in heating mode, the outdoor unit
may frost in low ambient temperature. To increase efficiency,
the unit will start defrosting automatically (after 2-10 minutes),
and then water will drained out from the outdoor unit.
b) In order to prevent cold air from blowing out of an indoor unit
at the start of heating operation, the indoor fan is automatically stopped. It may take some time before the fan starts. This is
not a malfunction.
Please read following information before asking for maintenance.
4.1 Symptoms that are not air conditioner troubles
Symptom 1: Outdoor unit makes a hiss noise
Protection mode
● In protection mode the system will stop automatically and the
outdoor main PCB will display the specified protection code. If
the unit displays protection or error code, contact your dealer for
servicing and maintenance.
● A slight hiss noise is caused by the heat-expansion and
cold-contraction of the heat exchanger as the temperature
changes.
● At the beginning or end of the defrosting process, a slight
hiss noise is caused by the four-way valve action.
● Error
When the system has error, the system will stop automatically
and the outdoor main PCB will display the specified error code. If
the unit displays protection or error code, contact your dealer for
servicing and maintenance.
● At the beginning or end of the running process, a sound
like water flowing in the valve occurs, which will be
amplified after 3-15 minutes. This sound may be caused by
refrigerant flow or discharge the drain water.
NOTE
Symptom 2: Outdoor unit heat exchanger discharge mist or water
Please switch off the power supply when protection or error
occurs. Do not restart until the problems are solved.
