OPERATION Display Panel D isplay panel C assette Type 5 4 3 D escription 1 Run indicator (Red) It lights on during operation. It lights off during SLEEP mode. 2 Emergency switch The filter clean indicator is reset when the switch is pressed. The unit will be started or stopped when the switch is pressed.
OPERATION Indoor Unit Control Mode Main general technical parameters (1) Remote receiver distance: 8 m. (2) Remote receiver angle: Less than 80 degrees. (3) Temperature control accuracy: ±1℃. (4) Time error: Less than 1%. Functions of the control function (1) Emergency switch Pressing the emergency button can start or stop the unit, or the unit can start up according to the automatic mode of operation.
Page 63
OPERATION Indoor Unit Control Mode (9) Auto re-start from power break When the power supply is recovered after a break, all presets are still effective and the air‑conditioner can run according to the previous setting. How to set/cancel: It can be set /canceled with wired remote controller. For details, see internal control parameter adjustment.
OPERATION Outdoor Unit Control Mode Control function Cooling Anti-Freeze Protection The indoor coil sensor functions as real time temperature detector of evaporator. It prevents the indoor unit evaporator temperature becoming too low. If the indoor coil temperature is too low, the compressor will automatically start protection mode. Overload Protection To prevent system overload caused by excessive pressure, the machine will implement real‑time detection when outdoor coil temperature is too high during cooling mode or indoor coil temperature is too high during heating mode.
OPERATION Control Logic Description (1) Outdoor fan and compressor stop. (2) Temperature setting function is disabled, and no setting temperature is displayed. (3) Indoor fan can be set to high/medium/low, but can not be set to auto. Cooling Mode Indoor fan running rules: In cooling mode, indoor fan runs all the time and the speed can be selected as high,(medium), low and auto.
Page 66
OPERATION Control Logic Description Heating Mode Indoor fan running rules: The indoor unit fan will not run until the indoor unit heat heat exchanger reches a high enough temperature. This is because the cold air prevention system is operating. After several minutes, the speed can be selected to high, medium, low, or auto.
Page 67
OPERATION Control Logic Description Auto Mode This mode can be chosen with remote controller and the setting temperature can be changed between 61°F~86°F(16°C~30) In auto mode, the unit will choose cooling, heating or fan -on ly mode according to T ( T =T1 -Ts).

OPERATION Control Logic Description Condenser High-tem perature Protection DC -Inverter outdoor unit AC will enter T3 protection if any of the following conditions is satisfied. TE1 0 TE1 1 Condition1: Cooling mode: When the outdoor coil temp. T3 keeps higher than T2 for 10 seconds, the compressor and outdoor fan will shut off.

Leak Check, Evacuation, and Charging (Triple Evacuation) Friedrich requires all installations are Leak Checked and Evacuated in accordance to the “triple evacuation” process. This process promotes a dry tight refrigeration system before opening the service valves. It recommended that a single port refrigeration manifold and hoses rated over 31.5psi be used.
