Disinfection filter (FDi)
Item # 339919
3. Passive disinfection filter (FDi) features
The passive disinfection filter (FDi) integrates a recirculation station that allows for the recirculation of treated water towards the inlet
zone of the system. Electromechanical components are included with that station as described below.
The recirculation station is equipped with a pump, an on/off float and an alarm float. Both the floats and the pump are connected to a
control box (DCU-FDi). This control box must be installed inside the house and be visible in case its light indicator is activated. The
following information explains the purpose of control box’s components.
The light indicator is activated when a water recirculation problem occurs. In that event, the problem must be verified: communicate
with Premier Tech Aqua’s After-Sales Service Department. The light indicator may be deactivated by pressing the “RÉARMEMENT /
RESET” button. This button can also be used to test a recirculation cycle and thus check the FDi’s status. To do so, press and hold
down the button for 5 seconds.
Electrical connections
All electric connections must be done by a certified electrician. Furthermore, the use of waterproof wire connectors is mandatory with
the recirculation station’s electric connection box. Premier Tech recommends that the electric connection box be installed outside of
the station, on a post above the ground surface. That way, it won’t be submerged and it will be always accessible.
Use one (1) independent circuit breaker for the connection of the DCU-FDi. Do not connect anything else to that circuit breaker
(e.g.: electric household equipment). The Ecoflo biofilter’s electric components must also be connected to independent circuit breakers
(one (1) circuit breaker to operate the pump and one (1) circuit breaker for the alarm box). Details for the connection of the Ecoflo
biofilters are presented in its Owner’s manual.
