The pump, which includes a frequency converter is supplied as a complete
unit for mounting on the wall and includes filters, mechanical thermal cutout,
pressure sensor, safety valve, bleed screws, manometer, solenoid valve,
high-pressure hose, etc.
The pump is used where the lowest rate of flow at partial load exceeds 5%
of the max. capacity at 70 bar. This means, for example, that the minimum
flow is 0.3, 0.6 and 1.1 l/min. for the pumps supplying 6, 12 and 21 l/min. re-
spectively at 70 bar.
The pump is supplied including mounting kit.
The mounting kit consists of:
2 x drain ball valve, 12 mm pipe
1 x straight connector
1 x T-connector
1 x drain plug valve ¾"
2 x threaded rod M10, 495 mm
3 x dowel 10 mm
3 x coach screw 10x70
2 x washer 6x14
4 x nut M10
1 x hose ¾" with collar band

437527 Electronic lime decomposer complete
Use of an electronic lime decomposer is recommended if water hardness
exceeds 20 dH.
The lime decomposer do not remove the lime, they break the lime crys-
tals down into smaller particles.
Most effective when the system is running continuously and not turned off.
To be mounted on the pipe after the pump and connected to 230 V. The
calcium decomposer comes with clip and assembly instruction.
Counteracts calcareous deposits in pipes and nozzles.
437439 Chemical filter w/clear glass non-return valve
Filter housing with 2 x 3/4" inside pipe thread and bleed port + statutory au-
tomatic non-return valve in front of the filter housing.
It is fitted with 437444 Phosphate cartridge which slowly releases phos-
phate and thus reduces the limescale on the nozzles quite substantially.
Phosphate filters are intended only for continuous use.
If the cooling unit is not running, the phosphate rock will dissolve into a thick
mass, which will damage the system.
The filter housing has a transparent glass to visually check the degree of
clogging, if any. But in general, the system is difficult to use.
