Activity control

Time for execution

Checking the function of water treatment system

A commissioning and after each prolonged seasonal unemployment.

Then each month.

Check the amount of chemicals stored

A commissioning and after each prolonged stop.

Thereafter every week.

Check the concentration of TAB1

Weekly.

Compare the parameters of the recirculating water quality parameters with reference
