1. Firstly, read the SDS and the detailed ‘Safe Operating Procedure’ (SOP).
  2. Turn off the glycol system.
  3. Connect required beer lines to the wash out line.
  4. We recommend flushing out remaining beer in the system with water, this allows the new chemical to be attacking the biofilm on the wall linings and not the beer itself; and it helps to reduce the temperature of the beer font. Maxi-Enzyme is most effective when font is closer to ambient temperature.
  5. Connect line from siphoning pump to the wash out line. Smaller
    venues can simply connect a drop lead from the ‘siphon spear’ to the wash out line, the system’s FloJet beer pumps will siphon.
  6. Fill ‘wheely bin’ (or suitable container) with sufficient 50°C hot water add dilution as indicated on the label.
  7. Open beer taps and continue until the liquid is light blue (see below), we recommend using a small bar glass for reference. Keep the taps open until the colour blue is the same as in the container in the coolroom. Maxi-Enzyme changes colour when it is working and removing contaminants, we wish to rest the once the ‘easy to remove’ dirt has been removed.
  8. Once all the lines are full of Maxi-Enzyme, begin 60 minutes rest.
  9. We recommend checking all taps to ensure full of Maxi-Enzyme.
  10. After 60 minutes rest (longer is ok), disconnect the line from the siphoning pump and connect the water (potable).
  11. Flush the lines minimum 4 x line volume, for example if line holds 3L, then flush minimum 12L of water through the line.
  12. Maxi-Enzyme once activated is pH9.2, so pH test strips can be used.
  13. Reconnect all beer lines to their respective beer kegs.
  14. Open the taps until beer reaches the taps, stop at first sign of foam.
  15. We recommend checking all taps to ensure full of beer.
  16. Turn on the glycol pump on the glycol chiller unit.
Container with siphoning spear.
Maxi-Enzyme is blue in colour, its a great reference there is cleaner in the system.
