Installation instructions
Hydraulic connection diagram
All of the automatic chlorine distributor or electrolyser models must be
installed after the heat pump.
The filter must be located in front of the heat pump.
A "By-Pass" system must be installed on all of the systems to facilitate
maintenance of the equipment and, if necessary, to adjust the water
output going through the heat pump.
This output adjustment is compulsory when the installation output
exceeds 17 m

SETTINgS: PRESSOSWICH SENSITIVITY.
The circulation safety is ensured by a pressoswitch, it is set in the factory
but it may be necessary to adjust it in cases of specific installation con-
figurations. Adjustment of the pressoswitch is done inside the electric box
(reference point 17 page 38).
The necessity for adjustment may be motivated by an early release of this func-
tion when the heat pump is located far below the level of the pool.
