1. The warranty is valid from the date of installation.
3. Warranty period: Two-years machine warranty for the consumer in EU territories. The warranty
does not include consumables (consumables include filters, RO membranes, and storage tanks).
4. Please keep the warranty in a safe place, for maintenance you must have your purchase invoice,
only then is the warranty effective.
5. The final seller provides the warranty service.
6.
The final seller can change the warranty conditions if the system installation wasn't made by seller's
specialist. The installation should be operated by professionals from the seller's side.

Failure
Experienced
Reason
Resolution Method
The machine
will not start
The power source is not connected
Check the power source or the power
source plug
Low inlet water pressure or no water
Check the inlet water pressure
Low-pressure switch failure, cannot connect the
power source
After connecting the inlet water,
measure the resistance, replace
High-pressure switch cannot be restored
After letting off the pressure, measure
the resistance, replace
Switch Mode Power Supply is burned out
Measure the output voltage, replace
The high
pressure pump
is working
properly, but no
water is being
produced
High-pressure pump has lost pressure
Measure the water pump pressure,
replace
Inlet water solenoid valve is faulty, no water can
get in (no pure water)
Replace the solenoid valve
A pre-filter is blocked
Observe the pure water and waste
water, replace the pre-filter
Non return valve is blocked (waste water, no
pure water)
Replace the non return valve
The RO Membranes is plugged
Clean or replace the RO membrane
The machine is
turned off but
waste water
has not stopped
Inlet solenoid valve failed, cannot effectively cut
off the water supply
Observe the waste water, replace the
inlet solenoid valve
Non return valve has lost pressure (small waste
water flow rate)
Observe the waste water, replace the
non return valve
After the
machine is filled
with water, the
machine starts
repeatedly
Non return valve has lost pressure
Replace the non return valve
High-pressure switch failure
Replace the high pressure switch
System is exhibiting a loss of pressure
After checking the non return valve,
check whether there is water leakage in
the pipelines
The pure water
flow is small or
not flowing
Pre-filter is plugged
Replace the pre-filter
RO membranes is plugged
Wash or replace the RO membrane
Inlet solenoid valve failure
Replace the inlet solenoid valve
Non return valve is plugged
Replace the non return valve
Coconut activated post carbon filter is plugged
Replace the post-carbon filter
High pressure pump pressure is not enough
Measure the high pressure pump water
pressure, replace
