In installation, please check specially the below items:
• If the connected units quantity and the total capacity is in the allowable range?
• If the refrigerant pipe length is in the limited range?
• If the pipe size is proper? And if the pipe is installed horizontally?
• If the branch pipe is installed horinzontally or vertically?
• If the additional refrigerant is counted correctly and weighed by the standard balance?
• If there is refrigerant leakage?
• If all the indoor power supplies can be on/off simultaneously?
• If the power voltage is in compliance with the data marked on the rating label?
• If the address of indoors has been set?
(1) Before installation
1) Before installation, check if the model, power supply, pipe, wires and parts purchased respectively are correct.
2) Check if the indoors and outdoors can be combined as the following.
Notice:
Total capacities of indoor units being used ≤ 100% of
rated capacities of outdoor unit.
Notice:
The branch pipe should be installed horizontally, the
maximum error angle should not exceed 10 degrees.

(2) Installation place selection
Air-conditioner can't be installed
in the place with inammable
gas. Or it will cause re hazard.
The unit should be installed at the
place with good ventilation. No
obstacle at the air inlet/outlet. And no
strong wind blows the unit.
The installation space refers to the
latter info.
The unit should be installed at the strong
enough place. Or it will cause vibration and
noise.
• The unit should not be installed at the
below places or it will cause damage.
• A place where there is corrosive gas
(spa area etc). A place blowing salty air
(seaside etc).
• A place with strong coal smoke.
• A place with high humidity.
• A place where there is device emitting
electrical interference.
• A place where voltage uctuations
• occur.
• A place where the water can drain
easily.
• A place where no other heat
sources will affect the unit.
• Consider snow depth when
installing outdoor unit.
• Install the anti-vibration rubber
between the unit and the bracket.
The unit should be installed in a
place where the cold/hot air or
noise will not interfere with the
neighbors.
