SYSTEM START-UP
The initial start-up of the UV system will depend mainly on how the system has
been installed but the following checks should always be carried out.
1 - Check that all pipework connections appear tight.
2 - Open both isolating valves which should be installed in the supply and return
pipe-work adjacent to the TES unit.
3 - This should flood the UV reactor body and then check for any water leakage.
4 - Start the main pool circulation pump and again check for any water leakage
now that the system is at operating pressure.
5 - Check the pressure reading at the TES unit pressure gauge to ensure that
the maximum pressure rating of 40 psi is not being exceeded.
6 - Check that the mains power supply to the unit is switched off and then
remove the top cap of the unit to allow inspection of the UV reactor thimble
and seal to ensure that there is no water leakage present.
7 - Re-instate the top cap.
8 - Switch on the mains power supply to the TES unit.
9 - The UV lamp should then be energised which will be indicated by a glow in
the top clear connection.
10 - When the power supply to the TES unit is electrically interlocked with the
main pool pump, stop the pool pump check that the lamp glow goes off.
Re-start the pump and check that the lamp energises again.
NOTE: IT IS ALWAYS PREFERABLE TO ELECTRICALLY INTERLOCK THE
POWER SUPPLY TO THE TES UNIT WITH THE MAIN POOL
CIRCULATION STARTER CIRCUIT AS A FURTHER SAFETY.
