This operation must be done by using gas cylinder and a
precise weighing machine obligatorily. The additional charge
is top up into the outdoor unit by suction valve via service

• Connect the low pressure manifold to the suction service
port, center manifold to the cylinder tank and close the
high pressure manifold (see figure below).
Purge all the flexible hose with refrigerant gas.
• Start the air conditioner unit.
