Pre Start Up Maintenance
(After Extended Shutdown)
Inspect thoroughly and clean indoor and outdoor units.
Clean or replace air fi lters.
Clean condensates drain line.
Clean clogged indoor and outdoor coils.
Check fan imbalance before operation.
Tighten all wiring connections and panels.
Check for refrigerant leakage.
Outdoor Models
The design of the A5LCY 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 qualifi ed Air Conditioner Service Technicians to ensure suffi 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.
