For R/RY-C/D Outdoor Models
The design of the R/RY-C/D 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 air tight test. These gases could cause severe
explosion and damage if expose to high temperature and pressure. It is recommended that only
nitrogen or refrigerant be charged when performing the leakage or airtight test.
