05. Operational Precautions
ACCESS PANELS AND GUARDS:
NEVER remove any access panels or guards as this could cause injury from electric shock
and burns from extremely hot components. Never allow any bodily parts such as fingers or objects to protrude through
the fan guards or any other opening as they could cause personal injury and damage the air conditioner.
SUPERVISION OF CHILDREN AND INFIRM PERSONS
: This appliance is not intended for use by young children or infirm
persons unless they have been adequately supervised by a responsible person to ensure that they can use the appliance
safely. Young children should be supervised to ensure that they do not play with the appliance.
RETURN AIR FILTER:
The air conditioner must never be operated without a return air filter as this will cause a build
up of dust and other contaminants on the indoor coil. This is very difficult to clean and causes the system to operate
inefficiently or even fail.
CRANKCASE HEATER PRECAUTION:
The main power ( Outside switch board ) to the system must be kept ON at all times
to prevent damage to the outdoor compressor unit. Should the main power be disconnected or interrupted for 6 hours
or longer, then no attempt should be made to start the system for 2 hours after the power has been restored to outdoor
unit. This allows the compressor to warm up, and remove any liquid refrigerant that may cause damage.
