NOTE

1 When numbers in brackets represent the equivalent length of all liquid pipes < 90m, means the

selected pipe size value.

2 It’s advised to use the Max. HP unit as the main unit. See above figure W4 outdoor unit (main unit),

Arranging the units with a sequence of Max. to Min.（i.e. W4>W3>W2>W1）.

3 The above figure is only available for the models such as D3,V4 and V4+ series with R410A refrigerant

when they are paralleled connected.

4 Please select T-style three direct links according to user guide of the external packaging bag; please

dumping the redundant T-style three direct links in the accessories and do not use for other purposes.

5 Pipe diameter of outdoor unit :

V4+:8～10HP, Gas/Liquid side:Φ25.4/Φ12.7;12～16HP, Gas/Liquid side:Φ31.8/Φ15.9;

V 4、D3:8～12HP, Gas/Liquid side:Φ25.4/Φ12.7;14～16HP, Gas/Liquid side:Φ31.8/Φ15.9.

6 All the pictures in this manual are for explanation purpose only. They may be slightly different from the

air conditioner you purchased(depend on model).The actual shape shall prevail.
