Service and Maintenance
For ALC Outdoor Models
The design of the ALC outdoor series allows servicing to be carried out easily. The removal of the top, front and
side panels makes almost every part accessible.
Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface
once every 3 months. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must
be regularly cleaned by quali
fi
ed Air Conditioner Service Technicians to ensure suf
fi
cient 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
