2. Handling mix-bed resin
Lehmann cleaning systems are delivered with full granulate bottle. The granulate
bottle is immediately ready for use. The following table displays the amount of pure
water that can be produced (in 1, right column) with one granulate bottle filling
depending on the water’s electrical conductivity (in μS; left column):
3. Replacing the mix-bed resin
The mix-bed resin must always be replaced
•
if the device measuring the water conductivity displays a value higher than
„050“ (μS).
If the measuring device displays a value higher than „010“ (μS), the granulate is
about 80% saturated and has to be replaced as soon as possible. It has to be taken
into account that the measuring value does not increase linearly but exponentially. A
working pressure of 5 bar applies to the water conducting system. Due to this, the
pressure must be removed from the granulate before replacement.
New granulate can be ordered in 25-litre-sacks (accessories), either as new granula-
te or as recycled granulate. The 25-litre-sacks must be stored in a suitable room. The
room must be well ventilated, dry and frost-free and have a clean and even ground
with sufficient load-bearing capacity. Recycled granulate has an about 80% produc
-
tivity compared to new granulate. To have the system ready for operation at any
time, it is recommended to permanently have at least one granulate bottle in reserve
(accessory).
Procedure
CAUTION
Electrical Shock Hazard! The live system and accessory parts and plugs must not be
touched with wet hands. Protective gloves must be worn.
1. Disconnect the system from power supply*
▷ Unplug the main plug
✓ The system is disconnected from the power supply.
2. Remove the system pressure
▷ Open all levers at the system and put them into position „open“ to do so
✓ The system ist pressureless.
3. Shut off the water supply and disconnect the hose connection at the quick faste
-
ner at the granulate bottle top
✓ The water supply is shut off and the quick fastener is disconnected.
4. Disassemble saturated granulate bottles
▷ Put granulate bottle into upright position
▷ Cautiously lift down the granulate bottle from the system trolley
•
The granulate bottle weighs about 30 kg in this status!
