Outdoor Models
The design of the MX-B 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.
• 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.
