Add the refrigerant according to the installation instruction for outdoor units. The addition of the R410A refrigerant
must be performed with a measure gage to ensure the specified amount is added. Compressor failure can be
caused by filling too much or too little refrigerant.
Proceed with the flare tube connecting operation to connect all the refrigerant tubes.
• Dual wrenches must be used for connecting the indoor unit tubing.
• For mounting torque, refer to the table on the right.
1. Connecting circular terminals:
The connecting method of the circular terminal is
shown in the Fig. Remove the screw, connect it to the
terminal tier after inserting it through the ring at the end
of the lead and then tighten it.
2. Connecting straight terminals:
The connection method for circular
terminals is shown in the Fig.
Loosen the screw before inserting
the line terminal into the terminal tier, tighten the screw
and confirm that it has been clamped by pulling the line
gently.
3. Pressing connecting line:
After line connection is completed, press the
connecting line with clips that should be pressed on the
protective sleeve of the connecting line.

Cutting or enlarging pipes should be carried out by
installation personnel according to the operating
criterion, if the tube is too long or the flare opening
is broken.
Cutting and Enlarging
Vacuumize from the stop valve of outdoor units with
vaccum pump. Refrigerant sealed in indoor machine
is not allowed to use for vaccumization.
Vacuumizing
Open all the valves of outdoor units. [NB: oil balancing
stop valve must be shut up completely when only
connected one main Unit].
Open All Valves
Check if there is any leakage at the connecting part
and bonnet with hydrophone or soapsuds.
Check for Air Leakage
