7.5 PROTECTION
-3 minutes delay at restart for compressor.
-Discharge temperature protection of compressor, compressor stops when the temp. of discharge is more than 115℃ and
last out 10 s. compressor runs when the temp. of discharge is less than 90℃.
-Temperature protection of compressor top, compressor stops when the temp. of top of compressor is more than 120℃,
compressor runs when the temp. of top of compressor is less than 105℃.
-When AC voltage ℃ 265V for 30 seconds, Outdoor Unit stops operation and alarms. When AC voltage ℃ 265V for 30
seconds, Outdoor Unit resumes operation.
-Inverter module Protection , Inverter module Protection itself has a protection function against current, voltage and
temperature.
-Sensor protection at open circuit and breaking disconnection
-Fan Speed is out of control. When Indoor Fan Speed is too high(higher than High Fan+300RPM)or too low(lower than
400RPM), the unit stops and LED displays failure information and can’t return to normal operation automatically.
-Cross Zero signal error warning. If there is no Cross Zero signals in 4 minutes, the unit stops and LED displays failure
information and can’t return to normal operation automatically.
-Current protection: When the current is more than ‘X’ A, the compressor stops.
(X is 7A for 14K 1x2 unit, is 14A for 18K 1x2 unit, is 13.5A for 21 1x3 unit, is 15A for 27K 1x3 unit, is 16A for 27K 1x4 unit and
is 21.5A for 36K 1x4 unit. )
-Outdoor condenser high temperature protection: Under cooling mode, if T3>65℃ for 3 minutes, the compressor will
stop. When T3<52℃, the protection is not valid.
-Pressure protection (just be available for 27K and 36K 1x4 unit): If low pressure is lower 0.03MPa, the compressor will
stop and when low pressure is higher than 0.10MPa, the compressor will restart. If high pressure is higher than 3.3MPa,

the compressor will stop and when high pressure is lower than 2.4MPa, the compressor will restart.
-Compressor pre-heating function: When the outdoor temperature is lower than 3℃ and the compressor stops operation
for more than 3 hours, or the outdoor temperature is lower than 3℃ and the power is just put on, the compressor enters
into pre-heating condition. When outdoor temp. is more than 5℃ or user operate it, pre-heating condition will finish.

the fan speed is kept at low speed.
-Heating: The set temperature decrease 1ºC per hour. Two hours later, the set temperature will maintain as a constant and
the air circulation is kept at low speed (Cold air proof function takes precedence over all).
-Auto: The Sleep Mode running function operates in accordance with selected running mode by auto
mode.
-After 7 hours, unit cancels this mode automatically.
