• Use caution when hoisting cables to lift the unit as the centre of balance is not at the
installation centre.
• Use expansion bolts to fix the mounting supports on the wall.
• Use bolts and nuts to fix the outdoor unit firmly on the supports and keep on the
same level.
• If the unit is installed on the wall or rooftop, the supports have to be firmly fixed so it
can resist strong weather conditions.
ORDINARY PIPELINE CONNECTIONS AND AIR PURGING
No dust, foreign objects, air or moisture should be allowed to enter the air conditioning
system. Careful attention should be paid when the pipeline connection to the outdoor unit
is made. Try to avoid curves as much as possible, as hardening or cracks may occur to the
copper pipes. Suitable wrenches should be used when the pipeline connection is done, so
as to ensure appropriate torque (refer to torque table below). Excessive torque may damage
the joints, while too little torque may lead to leakage.
