The supply line must be sized so that it can supply the minimum indicated pres-
sure and water volume when connected to this equipment. When dimensioning
the water supply, it is recommended to increase the available volume with 15-20
% compared to the minimum requirements listed in the table.
Note: It is recommended to mount a mixing system on the water
connection immediately before the outlet which is used.
Recomented water hardness 14-18 dH°. The equipment will
operate with water hardness exciding this level however, de
scaling of pump system, injectors and like must be
expected depending on use pattern and water quality.
Furthermore, wear of the mechanical parts will increase as well.
If not supplied, lter should be mounted.
5. Power supply
Connection instruction is mounted on the cables.
The phase order is subordinated.
Earth Leakage Circuit Breaker (ELCB).
When using an earth leakage circuit breaker (ELCB) also known as a residual
current device (RCD) or a residual current circuit breaker (RCCB) in a system
that incorporates a variable speed drive connected to 3 phase 400 V.
The trip level of the ELCB has to be 300 mA.
(30 mA used in house hold will malfunction due to earth leakage)
Service Switch:
The unit must always be connected to the main supply through a separate
service switch.
NB! Installation must always be in accordence with local legistration.
