(it is suitable for non-quick coupler)
No dust ,foreign articles,air or moisture should be allowed to enter the air conditioning system.Careful
attention should be paid when pipeline connection for outdoor unit is made.Try to avoid repeated
curves as much as possible,otherwise hardening or cracks might be caused to the copper pipes.Suitable

to following torque Table 1).Excessive torque might damage the joints while too little torque might
lead to leakage.
