The design of the outdoor series allows servicing to be carried out readily and easily. The removal of the
top side, front and back panel make almost every part accessible.
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 expose to high temperature and pressure.
It is recommended that only nitrogen or refrigerant be charged when performing the leakage
