MECHANICAL INSTALLATION
The following installation guidelines should be read carefully and understood
prior to fitting the system.
1 - The TES units are supplied ready assembled with exception of the two inlet
and outlet half unions, union seals and pressure gauge.
2 - The bottom connection is the “INLET” connection and the top connection is
the “OUTLET” connection. Never reverse these connections.
3 - The bottom connection should be fitted with the solid half union tailpiece
and the top connection should be fitted with the clear tailpiece connection.
4 - Two white union gaskets are supplied with the units and care should be
taken to ensure that the gasket is installed with the raised half round bead
fitting into the tailpiece face which has a matching groove to correctly locate
the gasket within the union.
5 - Place the gaskets onto the face of the union tailpieces and then secure in
position by threading the half union nut on the TES unit onto the tailpiece.
NOTE: DO NOT OVERTIGHTEN THE UNION NUT.
HAND TIGHTENING SHOULD BE SUFFICIENT.
OVERTIGHTENING WILL BREAK THE UNION NUT.
6 - The TES unit is supplied with a pressure gauge which should be fitted into
the top clear union tailpiece. When installing the pressure gauge into the fitting,
only use the square brass boss on the back of the gauge when using a spanner
but care should again be taken not to over-tighten the gauge.
NOTE: DO NOT OVERTIGHTEN THE PRESSURE GAUGE.
OVERTIGHTENING WILL STRIP THE PLASTIC THREAD.
DO NOT USE THE GAUGE BODY TO TIGHTEN.
The gauge should be fitted in a vertical position and never facing upwards as
water could enter the gauge and destroy it.
The gauge is used to indicate the pressure the pool pump is operating at and to
ensure that the maximum operating pressure of the TES unit of 40psi. is not
exceeded.
NOTE: DO NOT EXCEED THE MAXIMUM OPERATING PRESSURE
