under pressure. Wear Full Face Mask, Gloves and full length clothing and other PPE as required.
Ensure no product is inside the Autoclave during testing.
Clean drain and flush with boiling clean water regularly to prevent build up.

the unit serviced.
Have the unit inspected by a registered boiler inspector annually. ( Ensure chamber is registered
with the appropriate body for pressure vessels)
The cabinet is finished with stainless steel and to maintain appearance should be wiped over with a non
abrasive cleanser. The chamber is manufactured from stainless steel and may be cleaned with a solvent
and if grained stainless steel chamber a stainless steel scratch pad may be used. The pad should be
rubbed in the same direction as the grain pattern of the stainless steel.
The silicone gasket should be cleaned with detergent only, ensuring it is dried completely after washing. To
prolong life it may be stored at cool temperatures in a container of water. Gasket lubricant is available to
provide prolonged life and better sealing on the gasket.
The locking pins should be regularly greased with high temperature grease to reduce binding in the guides.
