Leakage Detection
1. With a leakage detector:
c. Check for leaks.
2. With soap water:
a. If a leakage detector is not available, use soap water for leakage
detection. Apply the soap water at the suspected position and let
sit for more than 3 min. If air bubbles emit from this position, there
is a leak.
I Feel Control Mode
After the controller receives an I FEEL signal and the ambient
temperature sent by the remote controller, the controller works
according to the ambient temperature sent by the remote controller.
Compulsory Defrosting Function
1. Start up compulsory defrosting function − Under the ON status,
set the heating mode with the remote controller and adjust the
temperature to 60.8
_
F. Press “+, −, +, −, +,−” successively within
5s and the complete unit enters the compulsory defrosting status.
Meanwhile the heating indicator on the indoor unit turns on for
10s and then off for 0.5s successively.
NOTE: If the entire unit malfunctions or stops operating due to the
protection function, the compulsory defrosting function can be started
after the malfunction or protection resumes.
2. Exit compulsory Defrosting Mode − After the compulsory
defrosting starts up, the entire unit exits the defrosting operation
according to the actual defrosting result, and the entire unit
resumes the normal heating operation.
Refrigerant Recovery Function:
1. Enter Refrigerant Recycling Function − Within 5 minutes after
energizing (unit ON or OFF status is ok), press LIGHT 3 times
within 3s to enter the Refrigerant Recycling mode. The Fo
indicator appears and the Refrigerant Recycling function starts.
At this moment, an authorized service technician closes the
liquid valve. After 5 minutes, stick the thimble of the
maintenance valve with a tool. If there is no refrigerant spraying
out, close the gas valve immediately and turn off the unit to
remove the connection pipe.
2. Exit Refrigerant Recycling Function − After entering the
Refrigerant Recycling mode, if the unit receives any remote
control signal or enters the Refrigerant Recycling mode for 25
minutes, the unit exits the Refrigerant Recycling mode
automatically. If the unit is in the standby mode before
refrigerant recycling, it remains in the standby mode after
Refrigerant Recycling is complete. If the unit is in the ON
status before the refrigerant recycle, it will still run in the original
operation mode.
Ambient Temperature Display Control Mode:
1. When the user sets the remote controller to display the set
temperature (corresponding remote control code: 01), the current
set temperature appears.
2. Only when the remote control signal is switched to the indoor
ambient temperature display status (corresponding remote
control code: 10) from the other display status (corresponding
remote control code: 00, 01,11), the controller displays the
indoor ambient temperature for 3s and then turns back to display
the set temperature. Under this mode, the indoor fan operates at a
set fan speed. The compressor, outdoor fan, 4−way valve and
electric heating tube stop operating. Users can select the indoor
fan to operate at either the high, medium, low or auto fan speeds.
The temperature setting range is 60.8−86.0OF.
Off−Peak Energization Function:
Adjust the compressor’s minimum stop time. The original minimum
stop time is 180s. The time interval between the compressor’s two
start−up times can not be less than 180+T s(0 T 15).
IMPORTANT:
T is a controller variable.
The compressor minimum stop time is 180s−195s. Read−in T into the
memory chip every time the user refurbishes the memory chip. After a
power recovery, the compressor can only start after 180+T s at least.
SE Control Mode
The unit operates at SE status.
X−Fan Mode
When the X−fan function is turned on, after turning off the unit, the
indoor fan still operates at a low speed for 2 minutes. Afterwards, the
entire unit turns off. When the X−Fan mode is turned off, after turning
off the unit, the entire unit turns off directly.
8º Heating Function
Under the Heating mode, you can set an 8
_
heating function with the
remote controller. The system operates at the 8
_
set temperature.
Turbo Fan Control Function
Set the Turbo function under the Cooling or Heating mode to engage
the turbo fan speed. Press FAN SPEED to cancel the turbo wind
function.
NOTE: There is no turbo function under the Auto, Dry or Fan modes.
Auto-Restart Function
The indoor unit is equipped with an Auto-Restart function, which is
carried out through the auto-restart module. In case of a sudden power
failure, the module memorizes the setting conditions prior to the power
failure. The unit automatically resumes the previous operation settings
(not including the swing function) 3 minutes after the power returns.
If the memorization condition is the Forced Cooling mode, the unit
runs in the Cooling mode for 30 minutes and returns to Auto mode at
a 75

set temperature. If the equipment was off before the
power went off, and it is required to start up after this power failure, the
compressor will have a 1 minute delay when powering on. In other
conditions, the compressor will have a 3 minutes delay at re-start.
