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.

where enough space can be ensured for maintenance.
where the lengths of the piping between indoor units and
outdoor units are within the allowable range (refer to Installation
of Outdoor Units)
where the distance of at least 3.28ft (1m) between indoor
units, outdoor units, mains supply, connecting wires and television
or radio should be kept as to avoid the image disturbance and
noises of the above electrical appliances. (Even if 3.28ft (1m) can
be ensured, noise might occur if there is strong electric wave.)
Additionally, equipments, television or other valuables can’t be
put under the unit as to avoid the condensed water of the unit
from dropping into the above articles, causing damaging.
