f) Observe the evaporator coils
i) If the air temperature is below 20°C, an even coating of
ice should cover the entire evaporator coil
ii) If the temperature is above 20°C, droplets of condensed
water should cover the entire evaporator coil.
4. Leave the unit to run for approximately 42minutes (from compressor
starting), after which the unit should go through a 4 minute defrost cycle.
During the defrost cycle the defrost solenoid valve is energized and a
warming of the evaporator coil can be felt.
If after carrying out the above checks the unit does not appear to
function correctly refer to the repairs section or your supplier.
