CAUTION:
- If moisture or foreign matter enters the refrigeration cycle, cooling ability will be lowered and abnormal noise will occur. Always immediately plug all open fittings after removing any refrigeration cycle parts to keep moisture or foreign matter out of the cycle.
Secure the connection part of the refrigerant pressure sensor using a spanner, and remove the refrigerant pressure sensor using a deep socket (24 mm {0.94 in} size (reference)) or an equivalent.
