3.6.5 Abnormal high pressure

In cooling mode

Check item

Detail

Does the outdoor unit fan run
normally?

Visual inspection

Is the outdoor unit heat exchanger
clogged?

Visual inspection

Is there clogging before or after the
expansion valve (capillary)?

▪

Check if there is a temperature
difference before and after expansion
valve (capillary).

▪

Check if the main valve unit of
expansion valve operates (by noise,
vibration).

Is the High Pressure Switch normal?

Check continuity by using a tester.

Is the outdoor unit installed under such
conditions that short circuit easily
occurs?

Visual inspection

Is the piping length ≤5 m?

Visual inspection

Does air enter the refrigerant system?

Conduct refrigerant collection and
vacuum drying, and then add proper
amount refrigerant.

Is the refrigerant overcharged?

Conduct refrigerant collection and
vacuum drying, and then add proper
amount refrigerant.
