Spillage
In the event of spillage or glassware fracture, do
not touch the mantle. Disconnect the product
from the mains electricity supply and allow the
product to cool. Wearing suitable hand
protection, carefully remove any pieces of broken
glassware. Wipe off all excess liquid from the
mantle and surrounding area using an absorbent
soft cloth. Drain off any residual fluid retained in
the mantle.
In the case of excessive spillage/ flask fracture,
invert the mantle and allow it to drain for
minimum of one hour. Then proceed with the
following drying out procedure. Place the
complete mantle, correct way up, in a heated
oven at 50°C for a minimum period of 40 hours.
Before further use, the mantle must be subjected
to electrical safety testing by competent service
personnel.
