Nozzle Cleaning Instructions
Remove and clean the sprays in sequence (do not mix sprays with other spray groups).
Chamber top to bottom: Cool down sprays x 1, Top sprays x 2, and rotary nozzles x 1,
Urine bottle sprays x 2 bottle hooks (unscrew from inside chamber)
Hold under tap and pressurise through the nozzle outlet in opposite direction of normal flow or clean in ultrasonic cleaner
if available. An appropriately sized Oxy-Acetylene tip cleaner pin may be used to clean out spray nozzle orifices. In areas
with hard water or high minerals in water supply, chemical de-scaler may be the quickest and easiest means to remove
build-up of deposits. Replace before removing next spray group
Stainless Steel Maintenance/Care
Under normal usage, stainless steel products require regular cleaning with a soft clean rag moistened with a mild detergent
followed by a water-moistened clean rag and then a dry rag.
The #4 satin finish steel should be protected against Muriatic acid and caustic or abrasive materials and harsh cleaning
detergents. In the event such agents cause discoloration, polish with a stainless-steel cleaner such as 3M Stainless Steel
Cleaner & Polish and a pad.
