Reduced flow rate
Malfunction
Solution
The flow drops below
15 L/min (4 gpm)
The pressure difference between the water supply line and the counter-
pressure from the system is too low. Open the pressure reduction valve again.
The flow is weak despite the
unrestricted supply line
The fine sieve in the outlet (right side) of the cartridge is blocked.
Loosen screw, rinse out fine sieve and reattach. See Fig. 7 below.

Drain sieve for residual water
Damage!
Preventative solution
The residual water in the resin tank can freeze causing
components to burst!
Frost damage can be prevented by blowing out residual
water with the supplied drain sieve. See Fig. 8 below.
In order to change the resin, the drain sieve must be
removed.

Apply drain sieve before blowing out residual water in the tank.
