unwanted effects or cause damage as described below:
• The pressure in the system rises.
• Power consumption rises.
• Cooling or heating efficiency drops.
• Moisture in the refrigerant circuit can lead to frozen and blocked capillary pipes.
• Water can cause corrosion of parts of the cooling system.
