See Figures 24~29 for installation of various models of wall connectors, which are for user’ s reference and are subject to change as per the actual application. When installing them, users should pay attention to the following points:

The sizes of the hole in the batten wall or the head tank should be proper. Too small sizes are not convenient for installation and may result in the threads’ damage. Too large sizes will affect the seal and location.

Locate the parts properly in their installation, especially the seal piece. Otherwise, the airtight property will be affected.

The producer has applied the sealing-glue (it is effective after several times of dismantling and installing) on the threads that need to be sealed when the product is delivered. Properly tighten the parts may ensure the seal.

When installing the slip head wall connector, properly apply the lubricant before putting the wall-crossing pipe through the valve’s seal washer for convenient installation.

There should not be any substance between threads. Apply the lubricant if necessary. Tighten the crossing pipe and nut properly to avoid any damage to threads.
