11. High and Low Pressure Sensors

W-2WAY ECO-i SYSTEM Outdoor Unit Repair Procedures

The outdoor unit connection ports for the high and low pressure sensors employ Schrader-type push-to-release valves. Therefore it is not necessary to recover refrigerant when removing and installing them.

11-1. Removing the High and Low Pressure Sensor

(1)Follow the instructions in “1. Removing Panels” and “2. Removing Electrical Component Box and Duct” and remove the corresponding components from the outdoor unit where the high pressure sensor will be removed.

(2)Disconnect the high & low pressure sensor connector socket (3P) (BLK) & (WHT) from terminals CN009 and CN024 on the outdoor unit control PCB of the outdoor unit where the high & low pressure sensor will be removed.

(3)Use 2 adjustable wrenches in combination to remove the high & low pressure sensors.

CAUTION

When removing the high & low pressure sensors, internal pressure will be applied by

the refrigerant in the outdoor unit. The high & low pressure sensor connection ports on 2 the outdoor unit employs a Schrader-type valve.

11-2. Installing the High and Low Pressure Sensors

(1) Use 2 adjustable wrenches in combination to install the high and low pressure sensors.
