Unit description
The steam steriliser ‘VAPOUR-LINE iite consists of:
Pressure gauge
The pressure gauge registers pressure (PSI). The pointer moves around the dial indicating precisely
the pressure within the unit.
Pressure gauge adaptor
The pressure gauge adaptor connects the pressure gauge to the vessel cover.
Pressure regulator
The pressure regulator is a solid one-piece unit. Accurate pressure readings can be controlled and
maintained by adjusting heat settings.
Air vent pipe
The pressure regulator fits over the vent pipe and allows excess pressure to be released.
Air vent cover lock
The air vent/cover locks automatically ‘vents’ or exhausts air from the vessel and acts as a visual
indication of pressure in the unit.
Locking bracket
The locking bracket on the inside of the vessel body engages with the air vent/cover lock to prevent
the cover from being opened when there is pressure in the unit.
Sealing ring
The sealing ring fits into the vessel cover and forms a pressure-tight seal between cover and body
during sterilisation.
Overpressure plug
The overpressure plug is located in the vessel cover. It will automatically pop out and release steam
in case the vent pipe becomes clogged and pressure cannot be released normally.

Electrical supply
220 – 240 V – AC single phase, 1300 W.
This unit must be earthed. It is delivered with a mains plug with safety contacts.
If replacing the mains plug, the mains lead (coloured green and yellow) must be connected to the
earth terminal on the new plug.
If using a mains supply without a protective earth, the unit must be connected to a safe earth.
Before using for the first time
1) Remove the air vent/cover lock from the vessel cover.
The cup portion of the air vent/cover lock, on the inside of the cover, unscrews from the pin.
2) Remove the sealing ring by simply pulling from the sealing ring groove.
3) Wash the cover and body with hot, soapy water. Do not submerge the cover in water or let the
gauge come in contact with any liquid. The inside mechanism of the gauge may be damaged if it
is submerged or if water is allowed to run over it. Scrub the sealing ring groove to remove the
manufacturing oils. Scour the inside of the canner body and cover with a non alkaline, aluminium
cleaner or a steel wool pad. Rinse with warm water and dry.
4) Re-insert the air vent/cover lock making sure the small gasket is in place.
5) Replace the sealing ring in the sealing ring groove.
The sealing ring is pre-lubricated; therefore, it is not necessary to apply oil to it. Frequent oiling
may cause swelling of the sealing ring.
6) If the cover is difficult to open or close use a pastry brushes, a piece of cloth or your fingertips to
apply a light coating of oil to the underside of the lugs on the vessel body. The cover should open
and close easily.
Be sure the vent pipe is open before each use by holding the cover up to the light and looking
through the vent pipe. If the vent pipe is blocked, excess pressure cannot be released through it.
Pressure will continue to build until the over pressure plug pops out of its cover opening.
Pressure is indicated on the dial gauge which registers the pressure inside the unit at all times. The
pointer will move across the dial as pressure is increased or reduced within the vessel. The
one-piece regulator is designed to rock only at 15 pounds pressure.
Do not strike the rim of the vessel body with any utensil as this will cause nicks which may damage
the rim and allow steam to escape. Pouring water into a dry overheated vessel may crack the metal.
The vessel has been designed so the cover will go on in only one position and rotate only in the
directions indicated for closing and opening. Press down on the cover handles to compress the
sealing ring and make the cover easier to close. The cover has the words CLOSE/OPEN embossed
on the top surface near a cover handle. Align the ‘V’ on the cover with the mark on the body handle
ENGLISH

for proper cover and body alignment. Turn the cover in the direction indicated to close until the cover
handles are centred directly above body handles.
Do not rotate the cover beyond this point.
When the cover is rotated to the closed position, the air vent/cover lock passes under the locking
bracket. When the handles are aligned, one over the other, the pressure regulator is placed on the
vent pipe and heat is applied, pressure will then begin to build within the vessel.
At this point, the air vent/cover lock lifts and locks the unit. The cover will remain locked as long as
there is pressure in the vessel. When pressure is reduced completely, the air vent/cover lock drops
allowing the unit to be opened.
Preliminary operations
1) This steam steriliser must only be used for a maximum pressure of 1.08 bar (121 °C).
2) The steam steriliser should be positioned in an area where there is adequate means for removal
of steam.
3) Connect plug to mains supply.
4) Introduce distilled water or demineralised water into the sterilisation chamber to cover the
heating system. Using distilled water avoids the production of calcareous deposits on the
heating element. 20 minutes of sterilising will use approximately 500 ml of water.
5) Two displays are lit on time/temperature command panel.
6) Before programming, it is necessary to erase the protection of the parameters (safety keys), see
paragraph 16.

Cleaning after use
1) The outside surface may be kept bright and shiny by cleaning with a good silver polish or simply
by washing with soap and water. Iron and various minerals in water may darken the inside but
this discoloration will in no way affect sterilisation. These stains are harmless and may be
removed by using a solution of water and cream of tartar. For each quart of water, use one
tablespoon of cream of tartar. Pour enough solution into the vessel to cover the discoloration (do
not fill over 2/3 full), then close cover securely. Place regulator on vent pipe and heat until 15
pounds pressure is reached. Switch off and allow the unit to stand for two to three hours.
Remove regulator, open and empty contents. Scour thoroughly with a soap impregnated steel
wool cleaning pad; wash, rinse and dry.
2) Each time the vessel is washed, remove the sealing ring and wash in warm, soapy water, rinse,
dry and replace in cover.
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.
4) If the pressure vessel becomes difficult to open or close and the sealing ring has expanded,
replace the sealing ring.
5) IMPORTANT: In time, the sealing ring may shrink and the air vent/cover lock, small gasket,
overpressure plug and pressure gauge adaptor may become hard and deformed. When this
happens, replace the sealing ring, small gasket, overpressure plug and pressure gauge adaptor.
The sealing ring, overpressure plug and pressure gauge adaptor should be replaced at least
every 2 years.
Before inserting a new sealing ring, clean the sealing ring groove with a brush. To ensure safe
operation of your unit, it is recommended that the pressure gauge adaptor and overpressure
plug be replaced whenever the sealing ring is replaced.
6) Anti-corrosion technique: When two different metals, with different chemical properties, come in
contact through an electrolyte an electron exchange is established. This process is known as
galvanic corrosion which starts oxidation of the weakest metal. In an aluminium autoclave this
natural effect can eventually lead to severe damage to the vessel.
