The quantity flow rate meter has to be controlled continuously during operation of
the precoat filter. Should - for any reason - the precoat filter suck air or should the
precoat pump fail, one would recognize this at the float of the flow rate meter and
one could switch the 3-way tap to „circuit“, so that the pure water cannot be
polluted.
The flow rate meter of the chlorine dosator also has to be controlled continuously,
so that no excess or less dosing can occur.
The motor pumps and the electrical pumps must in no case
operate in dry condition. This would cause a defect at the
axial face seal or stuffing box.
IV 1.6. Dismounting of unit and storage
Thoroughly drain the plant after backwashing, with special care the flow meters at
the filter tank and at the dosator (frost!).
Let all slide valves open, so that the air has free entry into the inside of the tanks.
Connections provided with blind couplings to be closed only during the drive, open
again in the depot.
The pumps have to be thoroughly drained before packing. Open the tap or screw at
the bottom of the casing and incline the pump correspondingly (frost!).
Before packing, all plant parts have to be cleansed. If a thorough cleaning cannot
be carried out at site, it has to be repeated in the depot or at any suitable place.
Before packing the raw water and pure water tanks have to be hung up at the small
rings. the raw water tanks can be flushed with pure water, then dry and folded acc.
to the attached plan (Attachment 3).
The plant is resistant to frost, provided that all plant parts have been thoroughly
drained.
The foldable tanks are made of rot-proof, artificial material coated textile. The hose
material is rot-proof as well. Despite this, hoses and tanks should be packed only
after air drying. All plant parts have to be checked on completeness and readiness
for use after each use.
