Filling the boiler with water - VAP 6
6.6.1
The first time the VAP 6 steam generator is switched on or when the water in the boiler is
running out, the "water low" warning light (6) comes on; simultaneously the element is switched off,
thus causing the "element on" indicator light (5) to go out.
The element will remain off until the boiler is refilled.
To fill the boiler with water proceed as follows:
• switch off the element via the main switch (4);
• release the steam in the boiler by pressing the gun trigger (9);
• unscrew, slowly and cautiously, the plug (15) so as to release any residual steam in the
boiler;
• fill the boiler with water;
• replace the plug and tighten it securely (15);
• turn the element switch (4) to ON.
To prevent temperature imbalance, do not use cold water when filling a
boiler that is still hot.
Regenerating the AD 8 water softener
6.6.2
To regenerate the AD 8 water softener proceed as follows:
• turn the water softener knob (30) to position 2 as illustrated in fig. 2, section 3.4.
Loosen the lid knob (25) and wait for the pressure to be released.
• Remove the lid by unscrewing the knob (25), then introduce the salt.
• Clean off any salt or resin that may have deposited on the lid seal, replace the lid and screw it
back in place properly.
• Turn the knob (30) to position 3 as illustrated in fig. 3, section 3.4, and let the salt water drain
from the hose (31) until it becomes fresh (this takes about 40 minutes).
• Turn the knob (30) to position 4 as indicated in fig. 4, section 3.4, wait about 30 seconds,
then bring the knob (30) to position 1 as illustrated in fig. 1, section 3.4.
In the intervening 30 seconds the unit will not be supplied with softened water.
When regeneration is being carried out the steam generator connected to the
softener is still supplied with water, but the latter is not softened.
Regeneration frequency depends on how often the AD 8 softener is used and the
degree of purity of the water. The installer will be able to provide
information regarding the hardness of the water at the installation site.
To maintain AD 8 water softener performance use the chart enclosed with this
manual to record regeneration data.
Use only NaCl (common cooking salt) to regenerate the softener. Do not use acid or
basic substances, solvents or chemical products.
