General Maintenance - VWR VAPOUR-Line lite II Manuel D'instructions

3) The air vent/cover lock may be removed for occasional cleaning or for replacing the small
gasket. Wash all parts in warm, soapy water. Use a soft cloth or small nylon brush to clean the
cover hole. The small gasket must be in place when re-assembling the air vent/cover lock.
4) The overpressure plug can be removed for cleaning by pulling it out of its opening from the
bottom part of the cover. After cleaning, re-insert the plug by pushing the round side of the plug
into the opening from the bottom part of the cover. When the overpressure plug is properly
installed the word (TOP) will be visible when viewing the outside of the cover. The dented portion
of the overpressure plug is visible when the bottom part of the cover is viewed. If the
overpressure plug is ever forced out of its cover opening due to excess pressure while sterilising,
it is important to have the vessel properly inspected before further use. Do not attempt to replace
the overpressure plug and ask for servicing.
5) Be sure the vent pipe is open before each use. Clean the vent pipe with a small brush or pipe
cleaner.
6) When your unit is not in use, invert the cover on the body and store in a dry place. Storing the unit
with the cover locked on may deform the sealing ring.

General maintenance

1) CAUTION: To ensure safe operation and satisfactory performance, replace the overpressure
plug every time you replace the sealing ring, or sooner if it becomes hard or deformed. In any
case replace the overpressure plug every 2 years. Failure to follow these instructions could
result in bodily injury or property damage.
2) If the body or cover handles become loose, tighten with a screwdriver.
3) If leakage of moisture or steam develops while using your unit, check the following possible
causes:

The formation of a small amount of moisture under the pressure regulator is normal when
heating first begins. This condensation is a result of the temperature of the pressure
regulator being lower than the rest of the vessel. If excess condensation continues, the vent
pipe may be loose and should be tightened with an adjustable wrench.

Leakage between the cover and body is usually caused by shrinkage of the sealing ring after
prolonged use. Replace the sealing ring, overpressure plug and pressure gauge adaptor.

A small amount of leakage around the air vent/cover lock is normal when sterilising first
begins. If leakage continues, the cover handles may not be fully aligned with the body
handles and, therefore, the cover lock cannot engage. Clean the air vent/cover lock
occasionally to ensure that it operates correctly.

A small amount of steam or moisture may be visible around the overpressure plug as
sterilisation begins. This will stop when the overpressure plug seals. If leakage continues,
clean or replace the overpressure plug.
