If necessary, install a pressure booster pump or consult a
plumber
Replace pre-filter cartridges
Measure permeate flowrate by closing tank valve 6 and
opening faucet 3. Use a measuring cup to check if the time it
takes to produce 1 L drinking water is as follows:
– 8 minutes with 50 gpd membrane;
– 5-6 minutes with 75 gpd membrane;
– 4 minutes with 100 gpd membrane.
If it took twice as long or more to produce 1 liter of water, the
membrane may need to be replaced (refer to the store where
you bought this product)
Straighten the tube
Pressure in the empty tank should be 0.4-0.6 bar (6-9 psi).
Charge the tank to the above pressure
The air will go away by itself with continued
operation of the system
Check your water supply pressure. If necessary, install a
pressure regulator or refer to a plumber
