The design of the MLC outdoor series allows servicing to be carried out readily and easily. The removal of the top side,
front and back panel make almost every part accessible.
Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface once
quarterly. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be regularly cleaned
by qualified Air Conditioner Service Technicians to ensure sufficient heat exchange and proper operation. Otherwise, the
systems life span may be shortened.
CAUTION!
Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit
when performing a leakage test or an airtight test. These gases could cause severe explosion and damage if
exposed to high temperature and pressure.
It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight test.
