Table 1 Torque based upon the wrench to be used
In case of the users purchasing the machine for quick
coupler,there is no need to do the air purging procedures
and the following pipeline connection procedures should
be adopted:
1.Remove the dust caps from the indoor and outdoor units,
and the connecting pipe.
2.Align the joint counter of connecting pipe with the proper
indoor and outdoor joint conic surfaces,tighten the connecting
nut manually.Then,make it secure with a wrench as shown
Fig. 6 ,applying to above torque Table 1.
3.Remove the two valve core caps from the outdoor unit.
4.Turn on the high and low pressure valve cores with an
socket wrench,then tighten the two valve core caps of the
outdoor unit (Fig.7).
5.Finally ,wrap the hot insulating cotton around the joints
of indoor and outdoor units.
1.Connecting pipe bending minimum radius parameters
(Table 2)
2.Quick coupler assembly and disassembly limit:
the assembly and disassembly times are inadvisably
more than 7.
*Notes on installation of quick coupler:

*Special pipelines connection
(it is suitable for quick coupler)
