5.12 Refrigerant Amount to be Added
Calculate the added refrigerant according to the diameter and
the length of the liquid side pipe of the outdoor unit/indoor unit
connection. Calculate the refrigerant adding amount, adding
refrigerant R410A.

NOTE: R410A refrigerant should be added in liquid quantifiedly by
electronic scale.
5-13 Manifold installation key points
Install it in a horizonal level, error angle should less than 10°.
It may result in damage if installing in a wrong way
6. ELECTRICAL WIRING
CAUTION
Please select power source for indoor unit and outdoor unit
respectively.
The power supply has specified branch circuit with leakage
protector and manual switch.
The outdoor unit model which corresponding to different outdoor
unit power supply should refer to the nameplate.(Please set all
the indoor unit power of one system into the same branch circuit.)
Please put the connective wire system between indoor unit and
outdoor unit with the refrigerant system together.
Use 3-core shielded wire as indoor unit and outdoor unit signal
wire.
The installation should comply with local electric standard.
Power wiring should be engaged by specialized electrician.
