Meaning

High pressure abnoramlity 1 (Outdoor unit): 1. When pressure sensor detects 3.87MPa or more during operations (the first time), outdoor unit stops once, mode is changed to restart mode after 3 minutes, then the outdoor unit restarts. 2. When a pressure of 3.87MPa or more is detected again (the second time) within 30 minutes after first stop of outdoor unit, mode is changed to restart mode after 3 minutes, then the outdoor unit restarts. 3. When 3.87MPa or more pressure is detected again (the third time) within 30 minutes after stop of out | High pressure abnoramlity 2 (Outdoor unit): When pressure sensor detects 0.098MPa or less just before starting of operation, error stop is observed with code No.“1302” displayed.

Possible causes

(1) Poor operations of indoor → LEV Heating (2) Poor operations of ball valve. (4) Clogging of indoor unit filter. (5) Fall in air volume caused by dust on indoor unit fan. (6) Dust on indoor unit heat exchanger. (7) Indoor unit fan block, motor trouble. (2)~(7) : Rise in high pressure caused by lowered condensing capacity in heating-only and heating-main operation. (9) Dust on outdoor unit heat exchanger. (10) Outdoor unit fan block, motor trouble, poor operations of fan controller. (8)~(10) : Rise in high pressure caused by lowered condensing capacity in cooling-only and cooling-main operation. (11) Poor operations of solenoid valves SV1 (Bypass valves (SV1) can not control rise in high pressure). (12) Thermistor trouble (TH5, TH6). (13) Pressure sensor trouble. (14) Control circuit board thermistor trouble, pressure sensor input circuit trouble. (15) Thermistor mounting failure (TH5, TH6) (16) No connector for pressure switch (63H), disconnected wire. (17) Fuse melting on the control board (F01 or F02). (1) Fall in internal pressure caused by gas leak. (2) Pressure sensor trouble. (3) Film breakage. (4) Coming off of pin in connector portion, poor contact. (5) Broken wire. (6) Pressure sensor input circuit trouble on control circuit board.
