Before you begin, always disconnect power sources before installing or making connections with all applications. It is
important that a system of safe working practice is applied to the installation, use and maintenance. Always ensure the
water system is drained before commencing work.
Step 1 Choose a location to install the In-Line Pressure Switch. When choosing an installation location, you must
consider the following:-
i) The location must allow access to the pressure switch for adjustment and mainentance
when required.
ii) The pressure switch must be installed in the pipework, on the outlet side of the pump before
any T pieces. This means that the opening of any tap in the system will activate the pressure
switch.
iii) The pressure switch must be screwed to a surface or suspended in the pipework.
