Check the water system (flush
or tap left running or obvious or
hidden leak). Manually open the
inlet valve if no leak is found, or
call COMAP after-sales service.
Screen frozen, touch screen

Firmware inoperative
Program updated via USB key via
a qualified technician. Contact
COMAP after-sales service
Water leak in the machine
Badly tightened unions, damaged
seals, old seals, crack following an
overpressure, shocks, etc.
Close the device's inlet valve, set
it to bypass (shunt), and contact
COMAP after-sales service.
Disconnect the power supply cable from the unit. The unit will restart in Maintenance
Mode, powered by the battery unit. Next, remove the cover by removing the
four screws.
If the electrical power supply is absent, the anti-scaling treatment and disinfection
treatment (UVc lamp) functions will not be provided. The device's power operated
inlet valve will be closed via an interlock via the battery unit. The power operated
valve can be opened to obtain untreated water (the 90μm/40μm filtration and
anti-drop, micropollutant treatments are still active) by actuating the pushbutton
(Fig. VII-1) using a fine screwdriver. If the power cut continues for a long time, you can
switch the battery unit OFF to preserve battery life. Note: this operation will prevent
the power-operated inlet valve from being operated again (closed or opened) without
mains power being restored.
Disconnect the device's power supply cable before any maintenance operation takes
place. The unit will restart in Maintenance Mode, powered by the battery unit. Next,
remove the cover by removing the four screws.
Clean quartz tube and replace O-rings and quartz tube bearing seals. We
recommend you call on a certified technician or call COMAP after-sales service to
find out the details and procedures of these preventive maintenance actions.
Replacing the pressure sensors: the inlet and outlet pressure sensors are intended
to be recalibrated via the maintenance menu on the touch screen. Contact
COMAP after-sales service to obtain the recalibration procedure or to replace any
defective sensors.
Replacing the power operated valves: these valves are designed to perform many
opening and closing cycles. Contact COMAP after-sales service in case of any
defect.
Replacing the filter bowl O-rings: the filter bowl seals are wear parts that can
deteriorate over time and after repeated handling. Plan for their preventive or
corrective replacement in case of incorrect placement in the filter bowl groove
(pinching).
Prefilter mesh: self-cleaning. Can also be deep-cleaned by removing the bowl
from the prefilter and using a brush. Contact COMAP after-sales service to obtain
a procedure.
Seals: the purpose of the flat O-rings is to seal the device. They should be replaced
preventively within five years because of ageing.
Flow meter: the turbine must be cleaned preventively, or correctively in the event
of a clog. Contact COMAP after-sales service to find out the procedure.
Electronic board: to be replaced only in the event of failure. Remember to
disconnect it in the event of a storm or voltage surge. Contact COMAP after-sales
service in case of any malfunction.
Touch screen: the touch screen must be cleaned once a year using a product
suitable for touch screens. Do not use water, detergents, or any other product
not described as being suitable for cleaning touch screens. Do not carry out this
operation whilst the device is in operation.
