Set point stability, turnover, filtration and disinfection are the figures that decide whether a unit is fit for commercial use. Thresholds are anchored to PWTAG TN71, Ice Baths (August 2024).
How to use it
Work through section four with the supplier in the room, record the answers on the scorecard, then assign the verdict. A supplier who cannot give stability, turnover, disinfection or verification data has answered the question: the absence is the finding.
Before you buy
The question set we send suppliers covers what a specification sheet leaves out: set point stability under load, turnover, disinfection residual and the water testing log.
