6.4 Special function: “Scalding during polymerisation”
Scalding is possible hile the polymerisation process is under ay. The last stored
scalding time is used, not at the last stored scalding temperature, but at the default
temperature for the polymerisation process. Scalding is started by pressing Scalding
(2). The scalding process can be stopped by pressing Scalding (2) again.
Warning: All opera ions, including polymerisa ion, are s opped if you press S ar /

6.5 Manual operation
Once the unit is ready for use, you can, at any time, activate the hand spray by turning
the ball valve (horizontal). Settings should be as described under 6.2. When you have
finished, al ays return the ball valve to its original position (vertical).

55°C, ha is, he pump s ar s opera ion once he se empera ure
has been reached. On addi ion here is a safe y s ep: he hea ing
s ops au oma ically when he empera ure of he hea ing is higher
han 99 °C.
Warning: Risk of scalding!
Do no hold he hand spray by he nozzle or hose.
Do no poin he spray a living crea ures.
The wa er from he nozzle can be as ho as abou 95°C, so should
only be sprayed near he uni lid or he washbasin.
The ball valve ( op righ on housing) needs o be se horizon al
when scalding wi h he hand spray. To ake he pressure off he
hose and hand spray, always rese he valve o ver ical when hey

8 Main enance
8.1 Cleaning
In order to guarantee trouble-free operation, the unit should receive the follo ing
attention:
A leas 1x per week
−Change ater, adding Wax–Ex.
Quantity: approx. 4 ccm/1 litre ater, corresponding to approx. 90 - 110g per 20
litres.
−Clean level sensor ( hite plastic ring) ith nailbrush or similar.
Every 2 weeks
−Change filter ( hite side do n).
Every 4 weeks
−Clean unit ith Kalk–Ex.
Quantity: approx. 5ccm/1 k litre ater, corresponding to approx. 170 - 220g of Kalk-
Ex per 20 litres. – If heavy lime deposi , increase quan i y appropria ely -
The outside of the unit and fittings are best cleaned ith a sponge or soft cloth and mild
detergent.
The model pla e must al ays be easy to read and should not be removed.
- 14 -

To change he fil er and clean he level sensor (whi e ring), firs remove
he cap con ainers. The perfora ed pla e can hen be aken ou and you
can remove he fla fil er. When inser ing a new one, make sure ha he
whi e side is face down and ha he fil er fi s under he raised edge of
he base pla e. The base pla e is easily removed, giving ready access o
he level sensor and he hea er coil. Re-inser he base pla e wi h i s
raised edges facing upwards.
8.2 Maintenance
The WAPO-Ex does not need any special maintenance. Just make sure it is clean and
free of lime build-up.
8.3 Warranty
