2.1 Additional items
Screw connections
All screw connections are metric threads / sizes unless otherwise stated.
Screw securing
All retaining screws with diameters larger than 3mm should also be secured before they are tightened, with a separate
adhesive such as, recommended, Loctite 586 or similar.
Screw Torques
All retaining screws should only be tightened finger tight without additional leverage
Sealant
For areas requiring sealing with silicone we recommend Sista F 109 or similar.
Cleaner
For surface cleaning of components we recommend commercially available washing agents based on soap. Ensure all
parts are fully dry before reassembly.
Disinfectant
For standard disinfection of the work area we recommend spraying down with commercially available broad range
disinfectants. Wash down with distilled/deionised water then wipe down thoroughly with 70% ethanol or Isopropyl
alcohol. DO NOT USE COMPOUNDS CONTAINING HYPOCHLORITE SOLUTIONS OR CHLORINE
COMPOUNDS. These will adversely affect the stainless steel.
