Service & Maintenance
Pre start up maintenance
(After extended shutdown)
Q Inspect thoroughly and clean indoor and outdoor units.
Q Clean or replace air fi lters.
Q Clean condensate drain line.
Q Clean clogged indoor and outdoor coils.
Q Check fan imbalance before operation.
Q Tighten all wiring connections and panels.
Q Check for refrigerant leakage.
The design of the R/RY-C/D outdoor series allows servicing to be carried out readily and easily. The removal
of the top/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 qualifi ed Air Conditioner Service Technicians to ensure suffi 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.
