Caution
!
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 qualified Air Conditioner Service Technicians to ensure sufficient
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.
Pre Start Up Maintenance

• Clean or replace air filters.
• Clean condensates drainline.
• Clean clogged indoor and outdoor coils.
• Check fan imbalance before operation.
• Tighten all wiring connections and panels.

The design of the outdoor series allows servicing to be carried out easily. The removal of the top, front
and side panels makes almost every part accessible.
