memorised automatically.
7. After exiting programming mode, hold down
Stop/Start (8) for approximately one second to
start up the shower program. The program can
also be stopped at any time by holding down
Stop/Start (8) for around 5 seconds.
For the shower to operate the following conditions
must prevail:
The water temperature in the tank must not be
•
less than 55 ºC: otherwise the wax dissolved in
the water may solidify and clog the pump shaft.
The water temperature must not be more than
•
95 ºC, otherwise bubbles caused by boiling will
appear, leading to cavitation in the pump. If the
temperature exceeds 95 ºC the machine
disconnects the heating elements and attempts
to drop to this level.
When the shower is running lamp (4) is lit. The time
shown on display (2) is the time remaining until the
shower stops, while the figure shown on display (1)
is the shower water temperature.
LONG PROGRAM
SHOWER)
It is extremely easy to program a heating and
shower sequence for the water in the tank. Merely
proceed as follows:
1. Press the long program key (6 L). The lamp for
the long program (polymerisation + shower) will
light up.
2. Press function key (12) to enter programming
mode. Check that the top display reads "A0",
thus indicating that this step can now be
programmed. The LED for A0 (waiting time) on
the synoptic display should also light up.
3. Use the Up/Down keys (11 & 13) to bring up the
desired first step time on the lower display (2).
4. Press function key (12). Check that the top
display reads "A1", thus indicating that this step
can now be programmed. The LED for A1 (1st
ramp time) on the synoptic display should also
light up.
5. Use the Up/Down keys (11 & 13) to bring up the
desired second step time on the lower display
(2).
6. Press the function key (12) again. This time the
display will read "U1" to indicate that the end
temperature for
programmed.
7. Proceed in this way until the times and
temperatures for all steps are programmed in.
8. The sequence in which the steps appear on the
display when the unit is in programming mode
is as follows:

9. When programming is complete, or ant any
time during programming, programming mode
can be exited by pressing W/T (9), which acts
as an escape key. The program is memorised
automatically.
10. After exiting programming mode, hold down
Stop/Start (8) for approximately one second to
start up
program. The program can also be stopped at
any time by holding down Stop/Start (8) for
around 5 seconds.
Should you wish the program to end at step A2 and
miss out the second ramp and plateau, merely
allocate a time of 00.00 for steps A3 and A4 and
the same temperature for U2 as for U1.
The temperature may not exceed 110 ºC at the
plateaux U1 and U2. If you try to program a higher
temperature, display (2) will show "A" at step U1. If
+
you accept this, the water in the tank will be held at
boiling point throughout plateau 2.
Water may boil at slightly above or below 100 ºC,
depending on altitude above sea level, water
composition
means that if the boiling point programmed into the
unit is 100 ºC the polymerisation process may not
proceed to the next step because the set
temperature may never be reached.
Likewise, the polymeriser may go on to the next
step without the water having boiled properly. This
problem can be solved by selecting "A" at step U1.
The R-080060 polymeriser will then automatically
detect when the water boils and hold it at that
temperature throughout the step in question.
Another possibility is to detect the exact boiling
point in
programmed
parameters: A0=00.00, A1=00.00, U1=110ºC. The
temperature of the water in the tank will rise slowly
to a level at which it holds steady. This is the
laboratory boiling point, and this temperature
should be programmed whenever you wish to
polymerise at boiling point.
To prevent excessive moisture due to steam given
be
off by the
Mestraitua, S.L recommends that you do not
program the unit for more than 96 ºC. Remember
also that the fan of the unit will remain on until main
switch D is switched off, to prevent the control
module from overheating.
