Test Run & Fault Code

Your air conditioner may be subject to any change owing to the improvement of Haier products.
MRV series multi zone air conditioning systems can operate multiple indoor units in heating or cooling. When in cooling,

only units set to cool will run. Same logic applies for heating..
Turn power on for 12 hours prior to start-up to allow the crankcase heater adequate time to protect the compressor. All
indoor units on the same refrigeration system should use the unified power switch to
ensure that all indoor units are all powered on during system operation.
