1. Safety Protection
(1) Time Delay for Safety protection
z3 minutes delay for compressor ---The compressor is ceased for 3minutes before restarting to
balance the pressure in the refrigeration cycle in order to protect the compressor.
z2 minutes delay for 4-way valve---The 4-way valve will be ceased for 2 minutes late after
compressor to prevent the refrigerant-gas abnormal noise when the HEATING
operation is
OFF or switch to the other operation mode.
(2) Discharge temperature protection
There is a temperature sensor on top of compressor, when temperature on top of
compressor
exceeded the limit, system control will shut down the compressor and the display board will
show the error code.
(3) Lower voltage protection
When AC voltage 158V and keep it for 10 seconds, unit will be shut down for protection.
(4) Over voltage protection
When AC voltage 260V, unit will be shut down and recover while AC255V.
(5) Over current protection
When the current of outdoor unit is overload, controller shut down the unit immediately and show
error code.
(6) Compressor abnormity protection
When compressor start on or in the process of running, if there is no feedback to controller or
load of compressor is abnormity, the air conditioner will shut down, and show error code.
(7) IPM module protection
IPM module has high temperature & over current protection itself, if there is signal feedback to
IPM, the outdoor unit will shut down, LED on outdoor PCB will show the error code.
2. “Feel” Mode Operation
(1) When the “Feel” mode is selected, the operation mode and initial temperature set are
determined by the initial room temperature at start-up of the operation except to turn off the air
conditioner and operates it again.
(2) If the mode is change to “Feel” from other mode, the “Feel” mode doesn’t operate until
compressor stop for more than 3 minutes.
Mode Initial Room Temperature Initial Set Temperature
COOLING RT=26ഒ23ഒ
DRY 26ഒ!RT20ഒRT-2ഒ
HEATING for Heat Pump/
FAN for Cooling Only RT<20ഒ-
zIn the “Feel” mode, when the controller receives the up or down signal of temperature,
the set
temperature can adjust by 1ഒupper or lower. The biggest you can adjust by 2ഒupper or lower.
3. “COOLING” Mode Operation
(1) Compressor frequency control
According to difference room temperature and set temperature (¥t = RT-ST), running frequency of
compressor is controlled by electronic controller. When room temperature is much higher than set
temperature, the compressor will start at a high frequency, and as room temperature goes down, the
compressor running frequency will go down. When room temperature is lower than set temperature,
6
thecompressor will run at very low frequency. In general, unit will change its running frequency
according to¥t to make room temperature closing to set temperature.
(2) Outdoor temperature affects running frequency of the compressor
Outdoor temperature affect compressor’s running frequency. Difference inlet temperature of
outdoor unit is adapted by difference compressor running frequency. While outdoor temperature is
about 30ഒ, the compressor will run in high frequency.
If unit run in “cooling” mode and outdoor temperature is less than -2ഒWKHcontroller will shut down
compressor and show error code, while the ambient temperature is over 1ഒthe compressor will run
automatically
(3) Auto fan control in cooling mode
In cooling mode (include cooling in “feel” mode), fan speed is determined by
į
t, as the following
diagram:
4.“DRY” Mode Operation
(1) The system for DRY operation used the same refrigerant circle as the cooling one.
(2) When the system operates in DRY mode, at first it operates in cooling mode, the set
temperature (ST) is “RT-2ഒ´. After that, t he system will operate in cooling mode with lowest
fan speed for 30 minutes and then change to middle speed for 30seconds as a cycle. During
the course of this operation, you can’t use remote controller to adjust the fan speed but you can
control the vane direction.
(3) In the dry mode, when RTื12ഒWKHFRPSUHVVRUZLOOVWRSDQGRSHUDWHVDJDLQDW57ุഒ
5. “HEATING” Mode Operation (available for Heat Pump only)
(1) Frequency control
Same as the frequency control in cooing mode, the running frequency of compressor is
controlled by controller. Unit change its running frequency according to
į
t to make the room
temperature closing to the set temperature.
(2) Indoor fan motor control
1) Cold Air Prevention Control
zThe function is intended to prevent cold air from being discharged when heating mode
selected or while in defrosting.
zThe indoor fan speed will be controlled as following.

seconds since the stop of compressor.
2) Auto fan control (heating)
In heating mode (include in “I feel” mode) , fan speed is determined by įtas the following:
(3) 4-way valve control
In heating mode, 4-way valve will power on ahead of compressor for 5 seconds, and cut off
for 2 minutes later than compressor. 4-way valve will not power off unless the machine to be
switched off, mode changed or on the process of defrosting.
(4) Defrosting
Defrosting is controlled by the microprocessor.
When one of the following conditions is satisfied, unit comes into defrosting:
a.
Outdoor heat exchanger Temperature (OPT) is continuously less than 3ഒwhile the unit runs
for more than 40 minutes, and OPT is keeping under -6ഒfor more than 3 minutes.
b.
Outdoor heat exchanger Temperature (OPT) is continuously less than 3ഒmeanwhile the
unit runs for more than 80 minutes, and OPT is keeping under -4ഒfor more than 3
minutes.
c.
Outdoor heat exchanger Temperature (OPT) is continuously less than 3ഒwhile the unit runs
for more than 120 minutes, and OPT is keeping below -2ഒfor more than 3 minutes.
Before the air con comes into defrosting, compressor running frequency drop down to a
lower frequency firstly, then the compressor shuts down.
In defrosting, the max. frequency of compressor is F9 (a little less than the highest
frequency ). In this period all protection function are available.
In defrosting, LED showing by winking.
No matter what AC come into or out of defrosting, indoor fan motor speed is the same as Cold
Air Prevention Control.
While one of the following conditions is satisfied, unit comes out of defrosting and shifts to
heating mode:
a.
Outdoor coil Temperature (OPT) ı15ഒ
b.
The time of defrosting keeps for more than 10 minutes.

Air Conditioner Service Manual
zInstall the indoor unit at a height of at least 2.5m
from the ground.
To install, proceed as follows:
9.2.1Installation of the mounting plate.
1) By using a level, put the mounting plate in a
perfect square position vertically and horizontally.
2) Drill 32mm deep holes in the wall to fix the plate.
3) Insert the plastic anchors into the hole.
4) Fix the mounting plate by using the provided
tapping screws.
5) Check that the mounting plate is correctly fixed.
Note: The shape of the mounting plate may be
different from the one above, but installation
method is similar.
9.2.2Drilling a hole in the wall for the piping
1) Decide where to drill the hole in the wall for the
piping (if necessary) according to the position of
the mounting plate
2) Install a flexible flange through the hole in the
wall to keep the latter intact and clean.
The hole must slope downwards towards the
exterior.
Note: Keep the drain pipe down towards the
direction of the wall hole, otherwise leakage may
occur.
9.2.3Electrical connections---Indoor unit
1).Lift the front panel.
2).Take off the cover as indicated in the picture
(by removing a screw or by breaking the hooks).
3).For the electrical connections, see the circuit
diagram on the right part of the unit under the
front panel.
4).Connect the cable wires to the screw terminals
by following the numbering, Use wire size
suitable to the electric power input (see name
plate on the unit) and according to all current
national safety code requirements.
5).The cable connecting the outdoor and indoor
units must be suitable for outdoor use.
6).The plug must be accessible also after the
appliance has been installed so that it can be
pulled out if necessary.

7).An efficient earth connection must be ensured.
8).If the power cable is damaged, it must be
replaced by an authorized Service Centre.
9.2.4 Refrigerant piping connection
The piping can be run in the 3 directions indicated
by numbers in the picture. When the piping is run
in direction 1 or 3, cut a notch along the groove on
the side of the indoor unit with a cutter.
Run the piping in the direction of the wall hole and
bind the copper pipes, the drain pipe and the
power cables together with the tape with the drain
pipe at the bottom, so that water can flow freely.
9.2.5Connecting the pipes.
zDo not remove the cap from the pipe until
connecting it, to avoid dampness or dirt
from entering.
zIf the pipe is bent or pulled too often, it will
become stiff. Do not bend the pipe more
than three times at one point.
zWhen extending the rolled pipe, straighten
the pipe by unwinding it gently as shown in
the picture.
9.2.6Connections to the indoor unit
1).Remove the indoor unit pipe cap (check that
there is no debris inside).
2).Insert the fare nut and create a flange at the
extreme end of the connection pipe.
3).Tighten the connections by using two wrenches
working in opposite directions.
9.2.7Indoor unit condensed water drainage
The indoor unit condensed water drainage is
fundamental for the success of the installation.
1).Place the drain hose below the piping, taking
care not to create siphons.
2).The drain hose must slant downwards to aid
drainage.
3).Do not bend the drain hose or leave it protruding
or twisted and do not put the end of it in water. If
an extension is connected to the drain hose,
ensure that it is lagged when it passes into the
indoor unit.
