Install the device in a suitable working area. The air conditioning system can be controlled through the shut-off valve body 1. During installation, the copper pipe is directly inserted into the ZPUSH interface. The copper pipe is locked by the internal first check ring 7 and second check ring 9 to form an anti-reverse self-locking mechanism.
