1 Features
The proven Wassermann WAPO - Ex combination unit, now with an easy-to-read
multifunction display, is an extremely compact piece of bench top equipment, which is
used for scalding wax and for polymerisation. It can take 4 half-caps for scalding and/or
6 caps in a denture for polymerisation. A housing and chamber in stainless steel
contribute to its long service life.
The unit has a low-water monitor to protect the heater, and for scalding small items,
there is a recessed lid and a hand-held spray in non-heat-conducting plastic.
The special WAPO-Ex / IVOCAP model has an automatic water-level regulator.

3 Applications
The WAPO - Ex is used for scalding up to 4 half-caps and up to 6 caps for
polymerisation. A divider in the trough creates two separate chambers. You can also
scald small items using a hand spray.
Only use the device for this type of application.
4 Before you start
4.1 Unpacking / Transport
- Open the cartons, remove the packing materials, and carefully lift out the instrument
and accessories. Check that the accessories are correct (see 8.4).
− When transporting the unit, make sure that it has been disconnected from the power
supply. Use appropriate packing materials to avoid accidental damage.
4.2 Set-up and storage
− Set the unit up on a level surface.
− Use clamps to attach the drain hose supplied firmly to the unit and arrange a suitable
drainage system.
− Always set the unit up with sufficient workspace around it (check its dimensions). Do
not set it up out of doors.
- If the unit is to be stored for an extended period, protect it from dust and moisture.
It is very important to have the unit connected rigidly to a drainage
system as very hot water (about 95°C) is involved. It will also facilitate
emptying the unit completely for cleaning, for example.

5 Start-up
− Insert the power plug into the mains socket (220-240 V / 50/60 Hz).
− Insert the filter white side down.
− Fill the unit with water (about 20 litres) at least up to the white plastic ring in the
container.
− Turn on the main switch (green rocker switch).
− The unit immediately heats up to its default setting (65°C), or to the last stored
scalding temperature.
− When the desired temperature has been reached, the yellow LED (9) goes out and
the unit is ready for operation.
Wear heat-resistant gloves when working with the WAPO-Ex.
The WAPO - Ex has a dry-run protection device to prevent the heater
burning out due to a lack of water (red LED). A warning signal also
sounds while the program is running.
Make sure that the water level is always above the white plastic ring (in
the container), otherwise the heater will cut out automatically and the
red LED will flash.
If the unit is not to be used for an extended period, pull out the power plug.
